Slow Cooker Sausage Egg Breakfast Casserole

A hearty breakfast casserole that combines turkey sausage, cottage cheese, and cheddar with beaten eggs, slow-cooked until firm and bubbly. Perfect for weekend mornings, holiday brunches, or meal prep when feeding a crowd. The cottage cheese adds protein and creaminess while keeping the dish lighter than traditional versions. Green peppers and onions provide fresh crunch and color to balance the rich eggs and cheese.

Tip 1

Rinse cottage cheese thoroughly to remove the creamy coating for better texture and less liquid in the final dish.

Tip 2

Cook sausages in batches to avoid overcrowding the pan, which prevents proper browning.

Tip 3

Stir gently after adding eggs to ensure even distribution of ingredients without breaking up the sausages too much.

FAQ

Can I use regular breakfast sausage instead of turkey?

Yes, pork breakfast sausage works perfectly. Use the same amount and cooking method, though it will be slightly more rich and fatty than turkey sausage.

What if I don't have Spike seasoning?

Substitute with 1/2 teaspoon each of garlic powder and onion powder, or use your favorite seasoning salt blend to taste.

How long will this keep in the refrigerator?

Store covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the whole casserole in a 350F oven.
