8 Breakfast Casseroles to Make Your Mornings Better

Get ready to transform your morning routine with these eight incredible breakfast casserole recipes.

1. The Classic Sausage, Egg, and Cheese Breakfast Casserole

This is the quintessential breakfast casserole. It’s hearty, savory, and packed with all the classic breakfast flavors you love: savory sausage, fluffy eggs, and plenty of melted cheese, all layered with soft bread.

It’s a guaranteed crowd-pleaser and a perfect introduction to the world of breakfast bakes.

Ingredients:

• 1 lb ground pork sausage
• 1 large onion, chopped
• 1 loaf of day-old bread (like French bread or sourdough), cut into 1-inch cubes
• 2 cups shredded sharp cheddar cheese
• 10 large eggs
• 3 cups whole milk
• 1 teaspoon Dijon mustard
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• Chopped chives for garnish (optional)

Instructions:

1. In a large skillet over medium-high heat, cook the ground sausage and chopped onion until the sausage is browned and the onion is soft. Drain any excess grease and set aside.
2. Grease a 9×13-inch baking dish. Spread half of the bread cubes in an even layer at the bottom of the dish.
3. Sprinkle the cooked sausage and onion mixture evenly over the bread. Top with 1 cup of the shredded cheddar cheese.
4. Layer the remaining bread cubes over the cheese.
5. In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until well combined and smooth.
6. Carefully and evenly pour the egg mixture over the layers in the baking dish. Gently press down on the bread to help it absorb the liquid.
7. Sprinkle the remaining 1 cup of cheese over the top.
8. At this point, you can cover and refrigerate the casserole overnight or proceed directly to baking.
9. When ready to bake, preheat your oven to 350°F (175°C). Bake the uncovered casserole for 45-55 minutes, or until the center is set (a knife inserted in the middle comes out clean) and the top is golden brown and bubbly.
10. Let it rest for 10 minutes before slicing and serving. Garnish with chopped chives if desired.

2. Sweet and Indulgent French Toast Casserole

For those who prefer a sweet start to the day, this French Toast Casserole is a dream come true. It has all the flavor of classic French toast but with none of the hassle of dipping and flipping individual slices.

A cinnamon-spiced egg custard soaks into thick bread cubes, which bake up into a soft, custardy center with a slightly crisp, caramelized top.

Ingredients:

• 1 loaf of challah or brioche bread, cut into 1-inch cubes
• 8 large eggs
• 2 cups whole milk
• 1 cup heavy cream

• Maple syrup and fresh berries for serving

Instructions:

1. Grease a 9×13-inch baking dish. Arrange the bread cubes in the dish in an even layer.
2. In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, 2 tablespoons of brown sugar, vanilla extract, and 1 teaspoon of cinnamon until fully combined.
3. Pour the egg mixture evenly over the bread cubes. Press down gently to ensure all the bread is soaking up the custard. Cover and refrigerate for at least 4 hours, or preferably overnight.
4. When ready to bake, preheat the oven to 350°F (175°C).
5. Make the topping: In a separate bowl, combine the flour, 1/2 cup of brown sugar, and 1 teaspoon of cinnamon. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
