Overnight Amish Breakfast Casserole (Printable Version)

A layered casserole with sausage, potatoes, eggs, and cheese, perfect for easy make-ahead mornings.

# Ingredient List:

→ Meats

01 - 1.5 pounds breakfast sausage, casings removed

→ Vegetables

02 - 1 medium onion, finely chopped
03 - 1 red bell pepper, diced
04 - 1 green bell pepper, diced
05 - 3 cups frozen shredded hash brown potatoes, thawed

→ Dairy

06 - 2 cups shredded cheddar cheese
07 - 1 cup shredded mozzarella cheese
08 - 2 cups whole milk

→ Eggs

09 - 12 large eggs

→ Spices and Seasonings

10 - 1 teaspoon salt
11 - 0.5 teaspoon freshly ground black pepper
12 - 0.5 teaspoon garlic powder
13 - 0.5 teaspoon smoked paprika

→ Garnish

14 - 0.25 cup chopped fresh parsley or chives

# Directions:

01 - In a large skillet over medium heat, cook the sausage, breaking it apart with a spoon, until browned and cooked through, approximately 7 to 9 minutes. Remove with a slotted spoon and set aside.
02 - In the same skillet, sauté the onion and bell peppers until softened, about 4 to 5 minutes. Remove from heat.
03 - Grease a 9x13-inch baking dish and spread the thawed hash browns evenly in the bottom.
04 - Top the hash browns with cooked sausage, then the sautéed vegetables. Sprinkle cheddar and mozzarella cheeses evenly over the top.
05 - In a large bowl, whisk together eggs, milk, salt, black pepper, garlic powder, and smoked paprika until well combined.
06 - Pour the egg mixture evenly over the casserole. Cover tightly with foil or plastic wrap and refrigerate overnight, at least 8 hours.
07 - In the morning, preheat the oven to 350°F. Remove the casserole from the refrigerator and let stand at room temperature for 15 minutes.
08 - Bake, uncovered, for 50 to 60 minutes, or until the eggs are set in the center and the top is lightly golden.
09 - Cool for 10 minutes before slicing. Garnish with fresh parsley or chives if desired.

# Expert Advice:

01 -
  • You prep everything the night before and actually get to enjoy your guests instead of cooking frantically in your apron.
  • It feeds a crowd without requiring you to babysit multiple pans or worry about timing eggs to perfection.
  • Leftovers reheat beautifully, making it perfect for those mornings when you want something substantial without the effort.
02 -
  • Thaw your hash browns completely the day before or you'll end up with a watery, disappointed casserole that never sets properly.
  • That 15-minute room temperature rest before baking is not optional—it ensures even cooking from edge to center instead of overcooked edges and a jiggly middle.
03 -
  • If you're cooking for vegetarians or meat-free guests, separate out a portion of the base and eggs before adding the sausage—it takes an extra minute and makes everyone feel considered.
  • Don't skip letting the casserole rest at room temperature before baking; it truly changes the texture from slightly custard-like to perfectly set throughout.
