Classic Breakfast Sausage and Egg Casserole

The heart of the casserole is the egg mixture, made with eggs, milk (or heavy cream for a richer texture), salt, pepper, and seasonings like garlic powder or smoked paprika.
Once mixed, it’s poured over the sausage and bread, ensuring every bite is packed with flavor. A generous layer of shredded cheese—cheddar, mozzarella, or pepper jack—melts beautifully on top, adding a creamy, gooey finish.
Baking the casserole at 350°F (175°C) for 30-40 minutes results in a golden-brown top with a soft yet sturdy interior. It’s important to let it rest for 5-10 minutes after baking to allow it to set before slicing.
This casserole can be made the night before, stored in the fridge, and baked fresh in the morning for ultimate convenience.
Perfect on its own or served with fresh fruit, toast, or a side of crispy bacon, this Classic Breakfast Sausage and Egg Casserole is a comforting, crowd-pleasing dish that never disappoints.

Ingredients
  

  • 1 Ib breakfast sausage
  • 8 large eggs
  • 2 cups shredded cheddar cheese
  • 2 cups milk
  • 6 slices of bread
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon paprika
  • 1 teaspoon dried mustard
  • 1/4 teaspoon red pepper flakes
  • 2 tablespoon butter
  • Fresh parsley or green onions for garnish

Instructions
 

  • Preheat & Prep: Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or nonstick spray.
  • Cook the Sausage: In a large skillet over medium heat, cook the sausage until browned and fully cooked (about 5-7 minutes). Break it into crumbles as it cooks. Drain any excess grease and set aside.
  • Assemble the Casserole: Spread the cubed bread evenly in the greased baking dish. Sprinkle the cooked sausage over the bread. Add shredded cheese evenly over the top.
  • Make the Egg Mixture: In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, onion powder, paprika, and dried mustard. Pour the egg mixture evenly over the sausage, bread, and cheese. Let it sit for 5 minutes to allow the bread to absorb the liquid.
  • Bake the Casserole: Cover with foil and bake for 30 minutes. Remove the foil and bake for another 10-15 minutes, until the top is golden brown and the eggs are set.
  • Serve & Enjoy!: Let the casserole rest for 5 minutes before slicing. Garnish with fresh parsley or green onions and serve warm.
