This Keto breakfast casserole is perfect for a Saturday morning or a Sunday brunch. It’s full of savory sausage and moist zucchini. Make it for a crowd on the weekend or cook one up on Sunday to enjoy for breakfast for the rest of the week. However you serve it, this casserole is sure to be a hit.

Choosing Your Sausage

Breakfast sausage might seem like the obvious choice but there is no need to limit yourself. You can use leftovers, whatever sausage you have on hand or check out the list below for some ideas. Just remember to keep an eye on the nutritional values.

  • Italian Sausage – A classic, leftover Italian sausage from dinner can easily become breakfast the next day.
  • Chorizo Sausage – Add some Spanish spice to your breakfast casserole, a little chorizo goes a long way so try mixing it with another type of sausage.
  • Turkey Sausage – Switch it up with some turkey sausage, if your family isn’t convinced yet this a great recipe to convert them turkey sausage lovers.
  • Or try this recipe to make your own Keto sausage patties.

One Recipe, Endless Casserole Variations

Casseroles are great because with the same basic template, you can make hundreds of variations. Everyone has their favorite in my family and I’m sure yours will too. Be mindful of the nutritional values if you substitute but don’t be afraid to go for bold flavors, eggs and coconut cream are the perfect canvas for your masterpiece.

  • Go Tex-Mex with jalapeños, chopped bell pepper, and tomato.
  • Add your own twist on a French classic, Quiche Lorraine, with bacon, onions, leeks, and mushrooms.
  • Go California-style with a spoonful of mashed avocado and lime on the side.
  • Go down south to Louisiana, with bell peppers, celery, and onion, with some Cajun spice mix.
  • Or try my dad’s favorite breakfast casserole, with bacon, ham, spinach, and onions, sprinkled with paprika on top.

A Keto Brunch

This casserole is a filling breakfast on its own, but why not make it the centerpiece in a lavish Keto brunch. The trick to any good men is variation. When I make a brunch menu I always try to include something savory, something sweet, something baked, and something cold.
