For the Casserole Base:

• 1 pound breakfast sausage, casings removed
• 1 cup chopped onion
• 1 cup chopped bell pepper (any color)
• 10 large eggs
• 1 cup milk
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 2 cups shredded cheese (cheddar, Monterey Jack, or a blend)
• 6-8 slices of bread or biscuits, cubed or torn (stale bread works best)

Optional Add-ins:

Feel free to toss in some extra veggies like mushrooms, spinach, or jalapeños for a spicy kick. You can also switch up the cheese for something like Gruyere or Colby Jack.

How to Make the Casserole

Preparing this breakfast sausage casserole is straightforward. The key is to get a nice browning on the sausage and vegetables to build flavor.

Step 1: Prepare the Sausage and Vegetables

Preheat your oven to 375°F (190°C). In a large skillet over medium-high heat, cook the breakfast sausage, breaking it up with a spoon until it’s fully browned. Drain off any excess grease.

Add the chopped onion and bell pepper to the skillet with the sausage. Cook until the vegetables are tender, about 5-7 minutes. If you’re using any other vegetables like mushrooms or spinach, add them now and cook until softened.

Step 2: Assemble the Casserole

In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined. Stir in most of the shredded cheese, reserving some for topping. Add the cooked sausage and vegetable mixture to the bowl and mix everything together.

Grease a 9×13 inch baking dish. Layer the cubed bread or biscuits evenly on the bottom of the dish. Pour the egg mixture evenly over the bread. Make sure the bread cubes are submerged as much as possible to absorb the liquid.

Step 3: Bake to Golden Perfection

Sprinkle the remaining cheese over the top of the casserole. Cover the baking dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for another 15-20 minutes, or until the casserole is set, golden brown, and bubbly.

Let the casserole rest for about 10 minutes before slicing and serving. This allows it to set up properly, making it easier to cut into neat portions.

Serving and Storage Tips

This breakfast sausage casserole is fantastic served hot straight from the oven. It pairs wonderfully with a side of fresh fruit, a dollop of sour cream, or even some salsa for an extra layer of flavor.

Make-Ahead Magic

To save time on busy mornings, assemble the casserole the night before. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove the plastic wrap and bake as directed, adding a few extra minutes if it’s very cold from the refrigerator.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or in a warm oven. This casserole also freezes well; let it cool completely, then wrap individual portions or the whole dish tightly.

Enjoy this delightfully savory breakfast sausage casserole any day of the week!
