A well-made breakfast casserole is a perfect way to start the day, especially when feeding a crowd or preparing breakfast ahead of time. This 11×7-inch breakfast casserole combines hearty eggs, savory sausage, cheese, and vegetables baked to perfection, making it both flavorful and convenient. Its versatile nature allows for easy customization, and it can be prepared the night before for a stress-free morning.

Ingredients

8 large eggs
1 cup whole milk (or 2%)
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon garlic powder
1 cup cooked breakfast sausage, crumbled or sliced
1 cup shredded cheddar cheese
1 cup cooked hash browns or diced potatoes
1/2 cup chopped bell peppers (any color)
1/2 cup chopped onions
Optional: 1/2 cup chopped spinach or kale
Optional: 1/2 cup sliced mushrooms

Instructions

Preheat your oven to 350°F (175°C). Lightly grease an 11×7-inch baking dish with butter or non-stick spray.
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until well combined.

Spread the cooked hash browns evenly across the bottom of the prepared baking dish.
Layer the cooked sausage over the hash browns, followed by the chopped bell peppers, onions, and optional vegetables like spinach or mushrooms.
Pour the egg mixture evenly over the layered ingredients, ensuring all components are coated and distributed evenly.

Sprinkle the shredded cheddar cheese on top of the casserole.
Place the dish in the preheated oven and bake uncovered for 35-40 minutes, or until the eggs are set and the cheese is bubbly and golden.
Remove from oven and let sit for 5 minutes before slicing and serving.

Tips

Substitutions: Use cooked bacon or ham instead of sausage for variety. Dairy-free options like almond milk and vegan cheese can be used for dairy allergies.
Make-ahead: Prepare the casserole the night before, cover tightly with plastic wrap, and refrigerate. Bake in the morning for a quick breakfast.
Prevent sogginess: Make sure the hash browns are cooked and drained well before adding to avoid excess moisture.

Cheese options: Swap cheddar for Monterey Jack, pepper jack, or a blend of cheeses for different flavors.
