Why You’ll Love This Recipe

This Easy Sausage and Egg Casserole is a great dish to serve on any occasion. It’s not only quick to prepare but also packed with rich flavors from the sausage and cheese. You can customize it to suit your tastes with optional ingredients like bell peppers, spinach, or onions, and the addition of bread cubes gives it a comforting, hearty texture. Whether you prefer a traditional breakfast or something a little more adventurous, this casserole is sure to be a hit.

Ingredients

  • 1 pound breakfast sausage (Italian or spicy sausage works well too)

  • 6 large eggs

  • 1 cup milk

  • 1 cup shredded cheddar cheese (or preferred cheese blend)

  • 2 cups bread cubes (optional)

  • ½ teaspoon salt

  • ½ teaspoon black pepper

  • ½ teaspoon garlic powder

  • ¼ teaspoon smoked paprika

  • ½ cup diced bell peppers (optional)

  • ½ cup chopped spinach (optional)

  • ¼ cup diced onions (optional)

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Preheat the oven: Preheat your oven to 375°F (190°C). Lightly grease a 7×11-inch (or 8×11-inch) baking dish with butter or nonstick spray.

  2. Prepare the sausage: In a skillet over medium heat, brown the sausage, breaking it into crumbles as it cooks. Once browned, drain any excess grease and set aside.

  3. Mix the egg mixture: In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and smoked paprika until well combined.

  4. Assemble the casserole: Layer the cooked sausage, vegetables (if using), and shredded cheese in the prepared baking dish. If using bread cubes, add them to the casserole. Pour the egg mixture evenly over the top.

  5. Bake: Bake the casserole for 30-40 minutes, or until the center is set and the top is golden brown.

  6. Cool and serve: Let the casserole cool for 5 minutes before slicing. Serve warm and enjoy!

  • Add spices: For a kick, add red pepper flakes or cayenne pepper to the egg mixture.

  • Make it dairy-free: Use a dairy-free milk alternative and dairy-free cheese to make this casserole dairy-free.

Storage/Reheating

FAQs

1. Can I make this sausage and egg casserole ahead of time?

Yes, you can prepare this casserole a day in advance. Assemble everything, cover the dish with plastic wrap or foil, and refrigerate overnight. In the morning, bake as directed, adding a few extra minutes to the cooking time.

2. Can I freeze this casserole?

Yes, you can freeze this casserole. Once baked and cooled, wrap the casserole tightly in plastic wrap and aluminum foil. It will keep in the freezer for up to 2 months. Reheat by baking from frozen, adding additional time if necessary.

3. What can I use instead of breakfast sausage?

You can substitute breakfast sausage with Italian sausage, turkey sausage, or even plant-based sausage for a different flavor or dietary preference.

4. Can I add other vegetables to this casserole?

Yes, you can customize the casserole with vegetables like mushrooms, zucchini, tomatoes, or broccoli. Just make sure to sauté any veggies that release moisture before adding them to the casserole to avoid sogginess.

5. How can I make this casserole spicier?

Add some diced jalapeños or a pinch of cayenne pepper to the egg mixture for an extra kick.

6. Can I use a different type of cheese?

Absolutely! Try mozzarella, Monterey Jack, pepper jack, or even gouda for a different flavor profile.

7. Can I use a different type of bread for the casserole?

Yes, you can use any type of bread you like, such as sourdough, whole wheat, or gluten-free bread. Just make sure it’s cut into cubes to mix well into the casserole.

8. How can I make this casserole dairy-free?

You can substitute the milk with a dairy-free milk alternative, such as almond milk or oat milk, and use dairy-free cheese to make this casserole dairy-free.

9. How do I know when the casserole is done baking?

The casserole is done when the center is set and the top is golden brown. You can also insert a knife in the center — if it comes out clean, it’s ready.

10. Can I make this recipe without eggs?

Eggs are essential for binding the casserole, but you can use an egg substitute like silken tofu or a flaxseed mixture if you're looking for an egg-free option.

Conclusion

This Easy Sausage and Egg Casserole is the ultimate comfort food that’s perfect for any meal. It’s simple to make, highly customizable, and will keep everyone satisfied.
