Now it is one of my favorite make-ahead breakfasts because it reheats so well and tastes just as good the next day.

- High in protein without using eggs.
- Easy to prepare ahead of time.
- Great for breakfast, brunch, or lunch.
- Creamy inside with a golden cheesy top.

Why This Recipe Works (Quick Science)
The cottage cheese and Greek yogurt add protein and moisture while helping the casserole stay creamy. As the casserole bakes, the cheddar cheese melts and holds everything together. The potatoes soak up the flavors from the turkey sausage, giving every bite plenty of flavor without needing eggs.

- Let the casserole rest for 10 minutes before cutting.

Recipe
Step 1: Cook the Sausage and Onion

Add the cooked sausage mixture and 3 cups thawed diced hash brown potatoes into the creamy mixture. Stir until everything is evenly coated.
Step 5: Fill the Baking Dish
Spread the mixture evenly into a lightly greased 9×13-inch baking dish. Sprinkle the remaining 1 cup shredded reduced-fat sharp cheddar cheese evenly over the top.
