Beef Wellington has long been a symbol of high-quality cuisine. Utilizing luxurious ingredients and a preparation that requires patience, the dish is a classic for high-end restaurants. It is easy to see why whenever you get the chance to try a Wellington for yourself. The textures and flavors are so well established that it is nearly impossible to not enjoy each bite.

Though the traditional dish is fantastic, there is one problem that presents itself for those practicing the Keto diet: the puff pastry. But, that is what the Keto Summit is all about, finding delicious alternatives and new ideas so that nobody misses out on exquisite meals such as these. This Keto beef wellington takes advantage of all the best parts of the dish with some healthy alternatives to keep you on track.

Let’s Make This a Great Keto Dish

So, if that puff pastry is so valuable for the desired texture of a beef wellington, then how do we combat that? The answer is, we don’t really need to. The whole concept of the dish is excellent from the inside out. Honestly, there is nothing wrong with a delicious piece of filet mignon on its own. The other ingredients are a bonus.

Quality beef wrapped in mushrooms and prosciutto sounds good enough to us. Who needs the added carbs. When baked, prosciutto creates a crisp outside that may even be better than the original.

A Few Tips On Putting Together a Great Wellington

Sure, beef wellington is typically reserved for special evenings at fancy restaurants, but that doesn’t mean we can’t treat ourselves at home once and a while. Cooking up these meals with special names is not as intimidating as they seem. Remember food is food, once you are comfortable in a kitchen no dish is too hard to make.

Here are a few tips to help you through assembling a perfect Keto beef Wellington:

  • Start with quality ingredients. If you have the best elements, then the dish will emulate that.
  • Duxelle mushrooms are essential to this dish and should not be skipped. You can look up other recipes that involve many types of mushrooms, all of which should be Keto friendly.
  • Wrapping a tight wellington is critical. Using plastic wrap will help to get a grip and push out all of the unwanted space.

Make a Romantic Dinner For Two

If you are looking to make a romantic dinner for that special someone, then you have found it. Beef Wellington is a dish for two, and it is the perfect date meal. Plus, all of that work that you put into making the meal won’t go unnoticed. I mean, who wouldn’t love it if somebody made them a dinner as exquisite as this one. It would make anyone feel appreciated.

No pastry makes this beef wellington Keto and delicious.


For the Duxelles:

  • 3 large button mushrooms
  • 1 Tablespoon (10 g) onions, chopped
  • 1 teaspoon (3 g) garlic powder
  • 1/2 teaspoon (3 g) salt
  • 2 Tablespoons (30 ml) olive oil

Other Ingredients:

  • 1 9-ounce (252 g) filet mignon
  • 8 thin slices of prosciutto (or 4 ham slices)
  • 1 Tablespoon (14 g) yellow mustard
  • 1/2 Tablespoon (7 g) salt
  • 2 Tablespoons (30 ml) olive oil to cook in


  1. Preheat oven to 400 F (200 C).
  2. Make the duxelles by blending the mushrooms, onions, garlic, salt, and olive oil together until pureed.
  3. Then heat the mixture in a pan for 10 minutes on medium heat.
  4. Place a large piece of cling-film onto the counter and place the slices of prosciutto side-by-side (overlapping slightly) to form a rectangular layer.
  5. Spread the duxelles over the prosciutto layer.
  6. Sprinkle the 1/2 Tablespoon of salt over the filet mignon.
  7. Pan-sear the filet mignon in 2 Tablespoons of olive oil.
  8. Spread the 1 Tablespoon of mustard on the seared filet mignon and place in the middle of the prosciutto and duxelles layer.
  9. Use the cling-film to wrap the prosciutto around the filet mignon. Then wrap the cling-film around the package to secure it. Use a second piece of cling-film to pull the prosciutto-wrapped package tighter together. Place in fridge for 15 minutes.
  10. Remove the cling-film from the refrigerated prosciutto-wrapped beef and place on a greased baking tray.
  11. Bake for 20-25 minutes (it should be pink when you cut into it).
  12. To serve, carefully cut the Beef Wellington in half.
