Cheesy Keto Breakfast Casserole

keto breakfast casserole


  • 8 slices bacon
  • 1 onion, diced
  • 2 tablespoons butter
  • 1 pound ground breakfast sausage
  • 8 eggs
  • 1 cup heavy cream
  • 1 teaspoon Kosher salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 3 cups shredded sharp cheddar cheese, divided


  1. Cook the bacon in a skillet at medium-low heat or in the oven at 350°F until crispy. Reserve the bacon fat and chop the bacon up finely once it has cooled. This step can be done ahead of time.
  2. In a large skillet, melt the butter with reserved bacon fat and sauté the onion at medium-high heat for about 5 minutes until it begins to soften. Add the ground breakfast sausage to the skillet and stir continuously, cooking until browned.
  3. Preheat oven to 375°F. Whisk together eggs, heavy cream, salt, pepper, and garlic powder. Then whisk in the bacon, onion, and sausage with the egg and cream mixture. Finally, mix in 2 cups of the cheese.
  4. Pour the egg mixture into a greased/sprayed 9x13 casserole pan. Bake for about 35 minutes (rotating the pan after 15-20 minutes). Sprinkle the last cup of cheese on top and continue baking for another 10-15 minutes until golden brown and cooked all the way through.
  5. Cut into 8 equal pieces and serve (or refrigerate for a later meal).
