How to Make Hearty Sausage Egg Casserole

Prepare the Sausage & Vegetables

Create Egg Custard

Layer Components

Build the casserole with strategic layering for best texture and flavor distribution.

Bake to Golden Perfection

Transform the ingredients into a cohesive, satisfying casserole.

Baking Tips

For a make-ahead option, prepare the casserole the night before and refrigerate. Add 5-10 minutes to the baking time if baking straight from the refrigerator.

Use slightly stale bread for better texture—fresh bread can become too soggy.

Switch up the cheese varieties for different flavors—try Swiss, Gruyere, or pepper jack.

Add mushrooms or spinach for additional vegetables.

For a spicier version, use hot Italian sausage instead of breakfast sausage.

Ingredients

Custard Cream

1 pound breakfast sausage

6 large eggs

2 cups whole milk

1 teaspoon dry mustard

1/2 teaspoon salt

1/4 teaspoon black pepper

1/4 teaspoon garlic powder

1/8 teaspoon cayenne pepper (optional)

6 cups cubed day-old bread (French bread or brioche work well)

2 cups shredded cheddar cheese, divided

1/2 cup diced red bell pepper

1/2 cup diced green bell pepper

1 small onion, diced

2 tablespoons chopped fresh parsley (plus more for garnish)

1 tablespoon butter (for greasing baking dish)

Instructions

Grease a 9x13-inch baking dish with butter.

In a large skillet over medium heat, cook the sausage, breaking it into crumbles until no longer pink. Drain excess fat.

In the same skillet, add diced onions and bell peppers. Sauté for 3-4 minutes until vegetables begin to soften.

In a large bowl, whisk together eggs, milk, dry mustard, salt, pepper, garlic powder, and cayenne (if using) until well combined.

Add the bread cubes to the prepared baking dish, then layer with the cooked sausage and vegetable mixture.

Sprinkle 1 1/2 cups of shredded cheese over the layers, then pour the egg mixture evenly over everything.

Gently press down on the mixture to ensure all bread cubes are soaked in the egg mixture.

Cover and refrigerate for at least 30 minutes or overnight.

When ready to bake, preheat oven to 350°F (175°C).

Uncover the casserole and sprinkle the remaining 1/2 cup of cheese on top.

Bake for 40-45 minutes until the top is golden brown and the center is set.

Let stand for 10 minutes before cutting into squares.

Garnish with additional chopped parsley before serving.
