Overnight Amish Breakfast Casserole (Printable)

A hearty Amish casserole packed with sausage, eggs, cheese, and potatoes for a satisfying start to the day.

# What You'll Need:

→ 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

# How to Make It:

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 across the bottom layer.
04 - Top hash browns with cooked sausage, followed by sautéed vegetables, then 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 layers. Cover tightly with foil or plastic wrap and refrigerate overnight for at least 8 hours.
07 - In the morning, preheat the oven to 350°F. Remove casserole from refrigerator and allow it to 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 brown.
09 - Allow the casserole to cool for 10 minutes before slicing. Garnish with fresh parsley or chives if desired.

# Expert Hints:

01 -
  • You make it entirely the night before, so mornings are stress-free and you can actually sit down with your guests instead of hovering over the stove.
  • It feeds a crowd without any fussy plating or last-minute scrambling, which means you can actually enjoy the people around your table.
  • The flavors get better as everything sits together overnight—the eggs absorb all those savory, cheesy, meaty notes until it's basically breakfast perfection.
02 -
  • Do not skip thawing the hash browns completely—I learned this the hard way when I tried to save time by using them frozen, and the bottom of the casserole turned out soggy and separated.
  • The overnight rest is not optional if you want maximum flavor; the eggs absorb everything and the whole thing becomes cohesive and deeply savory in a way it won't if you bake it fresh.
03 -
  • If your oven runs hot, tent the casserole with foil partway through baking so the top doesn't brown too quickly before the center sets.
  • The smoked paprika is optional but genuinely changes the game—it adds a subtle depth that makes people wonder what your secret ingredient is.
