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 9x13 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.
Recipe 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.
