Ingredients and Variations

Eggs – Use fresh whole eggs, liquid eggs in a carton, or a carton of liquid egg whites, if desired.

Meat – Ground beef, cooked and crumbled oven bacon, or leftover chicken, turkey or sausage patties will work!

Vegetables – Use the veggies in this recipe or toss in other keto faves like sliced zucchini, finely chopped broccoli, tomatoes, or chopped kale.

Variations – Go meatless and place a layer of cauliflower rice or tofu on the bottom. As long as the ingredients are roughly the same size, any low-carb add-ins will work (perfect for using up leftover meats and veggies to save some bucks)!

How to Make Sausage Egg Casserole

  1. Cook sausage and onion in a pan. Add peppers, spinach, and mushrooms and cook until tender (as described in the recipe card, below).
  2. Whisk eggs with cottage cheese and seasonings.
  3. Spread meat and veggie mixture in a prepared pan and pour over whisked eggs.
  4. Sprinkle cheese over the top and bake until set and the cheese is golden brown. Top portions with a dollop of sour cream, a scoop of salsa, or avocado dip.

Tips for Success!

  • Small curd cottage cheese helps everything stick together and makes the casserole fluffy.
  • Be sure to break up the sausage so it’s in fine pieces while it’s cooking so the bottom of the casserole is more firm.
  • For best results, let the casserole rest before cutting so it firms up.
  • Keep sausage casserole covered in the refrigerator until it’s ready to serve again for up to 3 days. To reheat, simply pop it in the microwave, and add a little salt and pepper or other favorite seasonings!

    Can I use egg whites with this recipe? My cholesterol is pretty high so all the eggs are going to raise my cholesterol!

    1. Egg whites should work fine. But if your doing straight keto your cholesterol should go down any way, since your body will be burning fat for fuel instead of glucose.
