A savory layered breakfast dish featuring sausage, eggs, cheese, and potatoes, ideal for easy meal prep.

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

# Expert Tips:

01 -
  • You do all the work the night before, which means morning coffee time instead of breakfast scrambling.
  • It feeds a crowd without needing you to stand at the stove flipping eggs for an hour straight.
  • The overnight sit lets all the flavors get cozy together, making every bite taste like it was made with intention.
02 -
  • Those hash browns absolutely must be thawed, or water will release during cooking and make your casserole soggy instead of custardy.
  • Letting it sit overnight isn't just convenient; it's actually essential because it allows the bread to absorb the egg mixture properly and creates that perfect texture.
03 -
  • Use good sausage because it's the star flavor; cheap sausage tastes like regret, and your casserole deserves better.
  • Let the casserole come to room temperature before baking so the eggs cook evenly throughout instead of the edges setting before the center.
