Why You’ll Love This Recipe

  • Yielding 8 servings with a massive 20g of protein in each, this High Protein Egg Bake with Cottage Cheese is the perfect way to meal-prep delicious breakfasts for the week – just gently warm portions through in the microwave each morning.
  • Breakfast sausage, mushrooms, bell pepper and cheese add plenty of bold flavors and textures to this egg bake, while the cottage cheese helps give it a creamy, tender texture. It’s not just there to add extra protein!
  • This high protein egg bake is happily gluten-free, as long as you make sure they have not snuck any added ingredients into your bulk breakfast sausage.

Chef’s Tips

  • Sausage, mushrooms and bell pepper are a classic breakfast combo, but pretty much any ingredient that would work in a quiche, frittata or omelette will work in this egg bake recipe – it is also perfect for clearing the refrigerator!
  • In a hurry, slices of this egg bake are delicious by themselves (or perked up with a few shakes of your favorite hot sauce!) but you could also add fresh fruit or a smoothie on the side if you need or prefer a bigger breakfast.

Equipment

  • 9 x 13 inch casserole dish
  • immersion blender or regular blender

Instructions 

  • Heat oil in a medium skillet over medium heat. Add turkey sausage and cook for approximately 10 minutes, or until fully cooked. Transfer the sausage to a separate dish.
  • In the same skillet, add onion, garlic, and bell peppers. Sauté over medium heat for 4-5 minutes, until the vegetables are softened. Remove from heat and allow to cool.
  • While the sausage and vegetable mixture cools, prepare the egg mixture. In a medium bowl, combine eggs, cottage cheese, cheddar cheese, and salt and pepper. Blend thoroughly using an immersion blender or a regular blender.
  • Add the cooked turkey sausage and vegetables to the blended egg and cottage cheese mixture, stirring until fully combined.
  • Pour the mixture into a 9×13 inch casserole dish (or a slightly larger dish) that is nonstick or lightly sprayed with oil.
  • Bake for approximately 40-50 minutes, or until the egg bake is firm in the middle. If the top begins to brown excessively, cover with aluminum foil for the last 10 minutes of baking.
  • Allow the egg bake to cool for at least 10 minutes before cutting into even slices.

Notes

  • Breakfast sausage, mushrooms and bell pepper are a classic breakfast combo, but pretty much any ingredient that would work in a quiche, frittata or omelette will work in this egg bake recipe – it is also perfect for clearing the refrigerator!
  • In a hurry, slices of this egg bake are delicious by themselves (or perked up with a few shakes of your favorite hot sauce!) but you could also add fresh fruit or a smoothie on the side if you need or prefer a bigger breakfast.
