Keto Tuna Salads

Paleo Italian Tuna Salad

– Paleo Flourish

36 Totally Transformative Keto Tuna Recipes

Ingredients: sun-dried tomatoes, tuna, celery, extra virgin olive oil, garlic, parsley, lemon juice, salt, pepper.

The garlic and sun-dried tomatoes in this dish give the Italian influence and work well with the soft tuna. Canned tuna can be sourced quite cheaply, so this would be a budget-friendly dish for the family for lunch. You can serve this in cucumber boats or. Instead of adding the chopped celery, you could cut the celery into pieces and load the tuna salad onto them.

Lemon Black Pepper Tuna Salad

– Paleo Flourish

Ingredients: cucumber, avocado, lemon juice, tuna, Paleo mayo or olive oil, mustard, salt, salad greens (optional), black pepper.

Tuna is a delicious meaty fish and if you are using canned, it can be a great way to make a satisfying meal at a reduced cost, making it great for people on a lower budget. Combining the fish with fresh cucumber and creamy soft avocado gives you a combination of flavor and texture that will be guaranteed to please for a light summery meal or a quick snack.

Roasted Cauliflower Broccoli Tuna Bowl

– Paleo Flourish

Ingredients: cauliflower, broccoli, olive oil, lemon, salt, tuna (in brine or olive oil), fresh parsley or cilantro, tahini, gluten-free tamari soy sauce, sesame oil.

Roasting vegetables gives them a milder and sometimes sweeter flavor and cauliflower is perfect for roasting. The tahini gives this dish a bit of a kick, but it goes really well with the fish. This dish is simple but packed with flavor and texture and makes the ideal packed lunch, filling and satisfying, to keep you going through a busy day.

Ingredients: canned tuna fish, “real” mayonnaise (Duke or Hellman), dried onion flakes, salt, pepper.

Like a lot of quick and simple recipes, this one gives you basic instruction for a delicious tuna salad that you can experiment with if you want to. If you don’t have dried onion, you can use fresh, but I would suggest you use red onion as it has a milder, sweeter flavor than white onions. If you don’t want to use real mayonnaise, there are a load of recipes for Keto-friendly mayo out there!

Ultimate Dill Tuna Salad

Ingredients: tuna, mayo, dried or fresh dill, salt, pepper, hamburger dills.

If you are like me and are a great fan of tuna salad, here is a fantastic recipe for you to try! Make these for a tasty lunch and you will really enjoy the combination of soft and creamy tuna salad with the zingy taste of the pickles. Using small pickles would also make these ‘sandwiches’ perfect as party food. If you don’t like pickles you can substitute cucumber, but you will lose some of the flavor.

Avocado Tuna Salad

– Peace, Love and Low Carb

Ingredients: canned tuna, avocado, rib celery, garlic, mayonnaise, red onion, spicy brown mustard, Italian flat leaf parsley, salt, pepper.

This is such an easy recipe with only a few ingredients, and using the avocado shells to serve makes it look so appetizing and cuts down on the dreaded washing-up! Tuna salad is a great lunch-time meal and ideal for using up leftover tuna. If you are not too keen on adding onions, try using red ones instead as they are sweeter and not so strong.

Tuna Stuffed Endive with Avocado Oil Vinaigrette

– Ketogasm

Ingredients: endive, canned solid albacore tuna, red onion, avocado oil, apple cider vinegar, salt.

This salad recipe is quite straightforward, but the emphasis is on the flavor of the tuna. When you add the apple cider vinegar you will find it adds sharpness and cuts through any fatty taste from the fish. I would advise you taste the tuna salad mixture before adding seasonings, as some canned tuna is already salty enough. Can’t find endives? Just serve this on lettuce leaves!

Thai Tuna Salad Wraps

– Autoimmune Wellness

Ingredients: canned tuna, red onion, green onions, ginger, coconut cream, lime juice, fish sauce, Thai basil, romaine lettuce.

The Thai inspiration in this dish comes from the ginger, lime and fish sauce and can give you a lovely alternative to your normal tuna salad. The Thai basil has an aniseed flavor which is different to normal basil, but sets off the flavor of the tuna really well so it is worth giving it a go. If you are serving these as snacks you could serve on smaller leaves such as Baby Gem lettuce.

Tuna Blueberry Salad

– Adventures In Partaking

Ingredients: tuna, avocado, cucumber, kale leaves or salad greens, blueberries, radishes and/ or spring onion greens, lime juice, sea salt.

You might think it is a bit unusual to find fruit in a tuna salad, but I would suggest you try it first! The blueberries add a lovely burst of juice and fresh flavor, complementing the salty tuna. If you don’t much like kale you can use other salad greens like spinach for the bulk of this dish. This salad travels well, so you can pack it in a mason jar and take it to work for a lunch full of flavor and texture.

Keto Tuna Melts

Italian Tuna Mousse

– Adventures In Partaking

Ingredients: baby spinach, parsley, dried oregano, lime juice, avocado, tuna packed in olive oil.

This mousse can be made as smooth or as textured as you prefer, which makes it suitable to use as a dip or spread. It takes just a few minutes to make and can be made quite cheaply, yet is a delicious and tasty dish to serve at a party with crudités. If you can’t get tuna in oil, buy the one in water and drain well first, then you can add some olive oil to the mixture later.

Tuna Melt Stuffed Tomatoes (Contains Dairy)

– Beauty and The Foodie

Ingredients: tomatoes, tuna, mayonnaise, celery, parsley, mustard, lemon juice, golden flax meal (optional), sea salt, black pepper, cheddar cheese.

Serving a tuna melt in tomato halves instead of on bread makes it easier to eat, lower in carbs and very pretty to serve to guests. These ones have a creamy filling thanks to the mayonnaise and a little bit of heat from the mustard, which goes really well with the cheese. You can use any canned tuna, but if yours is packed in water, it might be a good idea to drain the fish first to remove excess moisture.

Easy Cheesy Baked Tuna Balls (Contains Dairy)

– Beauty and The Foodie

Ingredients: tuna, egg, grated cheddar cheese, parmesan cheese, golden flax meal, mayonnaise, garlic powder, onion powder, sea salt, olive oil or avocado oil, almond flour, black pepper.

What a lovely way to make tuna a much more interesting dish! These tasty, cheesy balls have a great crispy coating and would make a lovely lunch dish served with some dip of your choice. You could also serve these as an appetizer along with some fresh green salad leaves, although they are quite filling so restrict your portion size if necessary.

Zucchini Tuna Melt Boats (Contains Dairy)

– News For Chews

Ingredients: zucchinis, can of tuna, stalk of celery, Greek yogurt or use mayo if desired, lemon juice, dill, salt, pepper, garlic salt, onion powder, chili powder or cayenne pepper, extra virgin olive oil, cheddar cheese.

It can be very impressive when you serve stuffed vegetables, and these zucchini boats win out for a great dinner idea. The recipe can be made quite cheaply, so this is a great student dish or if you have a large family to feed. If you want to ramp up the flavor a bit you could add in some cayenne to give the tuna a real kick, or try using a smoked cheese instead of cheddar.

Keto Tuna Cheese Melt (Contains Dairy)

– Diet Doctor

Ingredients: mayonnaise or sour cream, celery stalks, dill pickles, tuna in olive oil, lemon juice, garlic, salt, pepper, cheese, cayenne pepper or paprika powder.

This is a two-in-one recipe as you not only have the tuna salad recipe, but also for the Keto-friendly bread it is served on! You have smooth and creamy tuna salad heaped on the bread slices with cheese bubbling on the top – perfect for lunch on a busy day as this will fill you up and keep you going till dinner. Tuna melts are also great for kids, but you might want to miss out the dill pickle.

Keto Tuna Melts (Contains Dairy)

– Bad Tuber

Ingredients: can of tuna, mayo, sour cream, eggs, cheese, sea salt or table salt, parsley.

These lovely tuna melts are baked in a muffin tin, so you can regulate the portion control easier. You can use whatever cheese you prefer, but I recommend you use quite a strong cheese like a mature cheddar, as the flavor of mild cheese can virtually disappear with baking. This recipe also works with chopped pre-cooked chicken instead of tuna and tastes great with parmesan.

Avocado Tuna Melt Bites (Contains Dairy)

– Ruled Me

Ingredients: canned tuna, mayonnaise, avocado, Parmesan cheese, almond flour, garlic powder, onion powder, salt, pepper, coconut oil.

With these wonderful tuna melt bites, the almond flour makes them look as if they have been coated in breadcrumbs and gives them a fantastic crispy coating which complements the soft and creamy inside. The avocado and tuna together are so rich that you won’t need too many of these! If you want a slightly different flavor you could try crab meat instead of tuna.

Mini Tuna Melts (Contains Dairy)

– Butter Is Not A Carb

Ingredients: tuna packed in oil, yellow onion, eggs, mayonnaise, sour cream, cheddar cheese, parsley flakes, salt, pepper.

If you are like me and have a bit of a problem working out portion sizes, perhaps making these mini bites will help. They are full of the traditional tuna melt flavors of tuna, cheese and cream but without the added carbs of the bread they are usually based on. Remember to grease the muffin tins really well, as some cheeses have a greater tendency to stick to the pan.

No-Bread Tuna Melt (Contains Dairy)

– Our Paleo Life

Ingredients: canned tuna, paleo lime mayo, baby dill pickles, cheddar cheese, scallions, salt, ground black pepper.

Here is another great recipe for tuna melts that don’t have the bread we normally would use. As these little tuna bites are baked in a muffin tin, they tend to set on the outside, making them easier to eat on the go, so these would be a good item to include in a lunchbox. As with many other tuna recipes, taste the mixture before you add any salt as some tuna can be naturally quite salty.

Keto Tuna Cakes & Boats

Paleo Coconut Tuna Fish Cakes

– Paleo Flourish

36 Totally Transformative Keto Tuna Recipes

Ingredients: tuna, fresh basil, jalapeno, eggs, coconut flour, coconut flakes, olive oil, salt, coconut oil.

Fish cakes are a real favorite with many families and these are quick and easy to prepare. You can use salmon instead of tuna if you prefer and these can be served on their own, with a salad or with a tomato or fruity salsa. This recipe is also good for batch-cooking, as you can prepare them and store them in the fridge and cook when required.

Smoky Tuna Pickle Boats

Ingredients: albacore tuna, smoked tuna, sugar-free mayonnaise, dehydrated onion flakes or onion powder, garlic powder, ground black pepper, whole dill pickles.

These pickle boats make a lovely dish for a family picnic as they are easy to eat with the fingers. The tang of the pickles sets off the smoky flavor of the tuna and we all know how well tuna and mayo go together! To make them look even more appealing for a party dish, sprinkle them with a little paprika or a few pink peppercorns for garnish.

Asian Tuna Cakes

Ingredients: canned tuna, eggs, shallot, garlic, Italian flat leaf parsley, coconut aminos or gluten-free soy sauce, fresh ginger, toasted sesame seeds, red pepper flakes, sea salt, black pepper, olive oil.

Fish cakes are a great dish to serve to make sure your family eats healthier as even the youngest members will love these. Canned tuna is normally quite cheap, so this recipe would also suit if you are a student or working to a budget. Just remember to drain all the water from the fish as this can make the cakes very crumbly. Serve these with green salad leaves and a wedge of lemon for a lovely filling lunch!

Tuna Mushroom Egg Bake

Ingredients: eggs, coconut milk, cayenne, garlic powder, Himalayan pink salt, dried chilies, onion, chestnut cremini mushrooms, bell pepper, spring greens, black pepper, canned tuna.

If you like frittata for breakfast, you are going to love this recipe! You have the ease of an egg bake but with the variety of flavors from the tuna and vegetables, giving you a hearty and satisfying start to the day. Any kind of mushrooms work well in this dish, but I like to change things up and use a variety of different ones as our local store sells mixed packs.

Ingredients: pumpkin, tuna, green onions, eggs, serrano pepper, salt, chili powder, garlic powder, black pepper, ghee or butter.

The color on the outside of these amazing patties is so rich that you just know they are going to taste great! Obviously these are a great way to use up pumpkin, but I often serve these at Halloween parties as the kids absolutely love them, although I tend to miss out the chili powder for kids. You can even serve these in Keto-friendly buns to make them super-easy to hold and eat.

Bacon Tuna Boats

– Popular Paleo

Ingredients: tuna fish, bacon, scallions, fresh flat-leaf parsley, rib celery, Mrs. Dash Original Seasoning Blend or any seasoning blend of choice, avocado, fresh lemon juice, black pepper, English cucumbers.

This is a perfect recipe for people who don’t, or can’t, use mayonnaise to bind the salad together. The creamy texture of the avocado makes a fabulous substitute, making this salad a great filling for cucumber boats. You may like to peel the cucumbers first as the skin can be slightly tough, but you can tell when you cut them whether you need to do this.

Tuna Fish Patties And Quick Coleslaw

– The Healthy Foodie

Ingredients: yellow fin tuna in water, egg, kalamata olives, green olives, fresh parsley, red onion, coconut flour, Himalayan or fine sea salt, cracked black pepper, birds eye chili.

These tuna patties have the added bonus of the earthy flavors of the olives, which would make these a great idea for serving for an Italian-inspired meal. Obviously it is totally up to you whether you use the chili or not, but the tuna carries the heat really well so don’t worry about it being overpowering. The coconut flour acts as a binding agent, but does not give off a coconut taste at all

Keto Tuna Cakes (Contains Dairy)

– iSave A to Z

Ingredients: cans of tuna in water, eggs, shredded cheese, pork rinds, Pico de Gallo (chopped onion, tomato and jalapeño).

When we were growing up, fishcakes were usually made with a mixture of fish mashed within an inch of life, and mashed potato. How I wish we could have had these instead! These little cakes are crunchy on the outside because of the pork rinds, and there is a little bit of heat from the jalapenos, but this is not enough to mask the flavor of the fish.

Waffled Tuna Cakes With Lemon Dill Aioli

– All Day I Dream About Food

Ingredients: Genova albacore tuna in olive oil, almond flour, avocado oil mayonnaise, green onions, salt, pepper, egg whites, fresh lemon juice, fresh dill, garlic.

Cooking these tuna cakes in a waffle maker gives them little pockets that hold the wonderfully fresh tasting aioli! The flavors of garlic and lemon go so well with the tuna and we all know how well dill matches with fish! If you are using any canned tuna, it’s best if you drain the fish well before attempting to cook these amazing waffles.

Other Keto Tuna Recipes

– Low Carb Yum

Ingredients: butter, garlic, heavy cream, unsweetened almond milk, Parmesan cheese, dried parsley, canned tuna, frozen spinach, provolone or mozzarella cheese.

If you are lucky enough to live in a country where you can buy bags of frozen spinach which is already cooked with heavy cream then this recipe can be super-quick to make. However if you don’t, it is quite easy to make from scratch. Just follow this recipe and you are good to go! I sometimes like to make this casserole without the cheese as it is already packed with flavor.

Incredible Tuna Pie (Contains Dairy)

– Low Carb Yum

Ingredients: almond flour, coconut flour, grated cheddar cheese, salt, paprika, butter, canned tuna, eggs, sour cream, mayonnaise, green beans, onion.

The inside of this amazing pie is creamy and delicious, with little pops of green from the beans to liven up the look of the dish. As this pie has vegetables inside it, there is no real reason to serve any side dishes here as the pie is filling on its own. If you really don’t like green beans, this amazing dish could be adapted by using broccoli florets instead, although you might want to par-cook it first.

Tuna “Noodle” Casserole

– My Heart Beets

36 Totally Transformative Keto Tuna Recipes

Ingredients: canned tuna, cream of mushroom soup, peas, spaghetti squash, fine sea salt, ground black peppercorns, turmeric powder, almond flour, butter or ghee.

This casserole uses spaghetti squash to give the ‘noodles’ and the sauce in the dish comes from mushroom soup. This gives the whole dish a richness of flavor along with the tuna and healthy turmeric. If you prefer, this could be made with zucchini noodles, but the cooking time would need to be adjusted so the noodles were not too soft.

Grilled Tuna Oscar

– Seasonal and Savory

Ingredients: tuna steaks, asparagus spears, crabmeat, butter, egg yolks, lemon juice, salt, ground white pepper.

This has got to be one of the most impressive tuna dishes available, and would be perfect to serve to guests at a dinner party. Fresh tuna is so meaty and has a totally different flavor to canned, and it is better slightly under-cooked than well done as it can be quite dry. So if you are out to impress, take your fishmonger’s advice and choose the best quality steaks you can get.

Tuna Avocado Lettuce Wraps

– The Healthy Foodie

Ingredients: hard-boiled eggs, canned light tuna, (Wild Planet), avocado, green olives, extra virgin olive oil, cumin, smoked paprika, garlic powder, cayenne pepper, white pepper, salt, black pepper, Boston lettuce leaves.

In this wrap recipe the olives and cumin give the earthy notes we expect from this Mediterranean-inspired dish, and they all sit well with the salty tuna. I find that some tuna salad recipes can be a bit dry, so if you find this you can add in a little peeled and chopped cucumber at the end of preparation and this should make sure the salad is moist and tasty.

Paleo Tuna Stroganoff

– Paleo Effect

Ingredients: paleo cream of mushroom soup, white albacore tuna, coconut milk, duck fat, yellow onion, garlic, coarse sea salt, black pepper, green peas, broccoli, baby portabella mushrooms, paleo breadcrumbs, toasted onion flakes.

Here is another case where the crunchy crumb topping helps to make this dish look amazing! Then inside you find moist chunks of fish and vegetables in a creamy mushroom sauce…even talking about it makes your mouth water! This would make a lovely family meal any time as it doesn’t take long to prepare; just remember if using canned tuna to drain it first otherwise the dish will be watery.

Seared Ahi Tuna Sushi Bowls

– PaleOMG

Ingredients: coconut aminos, sriracha, sesame oil, rice wine vinegar or coconut vinegar, salt, tuna steak or sushi grade tuna, avocado oil, cauliflower rice, cucumber, avocado, green onions, pickled ginger, black sesame seeds, white sesame seeds.

This amazing dish gives you all the flavors of sushi but without the hassle of having to arrange it and roll it up! Try to use the best quality tuna you can find as this makes a big difference to the whole dish, and marinade it for a few hours to allow the flavors to soak into the fish. You have a lovely mix of textures here, thanks to the creamy avocado and crunchy seeds, making this a show-stopper!

Tuna And Avocado Wraps

– Nom Nom Paleo

Ingredients: canned albacore tuna in water, scallion, jalapeno, avocado, lime juice, Kosher salt, freshly-ground black pepper, butter lettuce leaves, Pure Wraps or toasted nori (optional).

This is a great recipe for a tuna salad if you don’t want to use mayonnaise, as this one uses guacamole to bind the fish instead. This adds richness and creamy smoothness to partner with the fish. You have a bit of a kick from the jalapeno, but if you want to ramp up the heat you could add in a touch of harissa paste or tahini if you have it.

Spicy Tuna Deviled Eggs

– Keto Diet Blog

Ingredients: eggs, tuna, mayonnaise, Sriracha sauce, spring onion, salt, pepper.

Deviled eggs make excellent snacks, light lunch ideas or to serve as party food when you are entertaining and they can be prepared in just a few minutes. These ones have a bit of spice from the sriracha, but this could be reduced if you don’t want them too spicy. Garnish with finely chopped green onions or a sprinkle of paprika for a dish that looks and tastes amazing.
