Ingredients Method Notes

Ingredients
  

  • Ingredients
  • 1 lb breakfast sausage regular, Italian, or spicy
  • 6 large eggs
  • 1 cup milk
  • 1 cup shredded cheddar cheese or any favorite cheese blend
  • 2 cups cubed bread 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 finely chopped onion optional

Method
 

1. Cook the Sausage

Place a skillet over medium heat and add the sausage. Cook it while breaking it into small crumbles until fully browned. Once done, drain off the excess grease and set the sausage aside.

    2. Prepare the Egg Base

    In a mixing bowl, combine the eggs and milk. Whisk until smooth, then stir in salt, black pepper, garlic powder, and smoked paprika to season the mixture.

      3. Build the Casserole

      Lightly grease a baking dish. Spread the cooked sausage evenly across the bottom. If you’re using bread cubes, scatter them over the sausage. Add the shredded cheese and any vegetables you like, such as peppers, spinach, or onions. Pour the egg mixture over everything so it coats the layers evenly.

        4. Bake

        Preheat your oven to 375°F (190°C). Place the casserole in the oven and bake for 30–40 minutes, or until the center is fully set and the top develops a lightly golden color.

          5. Let It Rest and Serve

          Allow the casserole to sit for about 5 minutes after baking. This helps it firm up for easier slicing. Serve warm and enjoy.

            Tips to Customize Your Sausage and Egg Casserole

            Add Extra Heat
            If you enjoy bold flavors, mix in chopped jalapeños or choose a spicy sausage variety.
            Increase the Veggies
            Boost nutrition by adding vegetables like diced tomatoes, zucchini, mushrooms, or kale.
            Make It Diet-Friendly
            Swap traditional sausage for plant-based sausage to create a vegetarian version. Leaving out the bread also makes the casserole low-carb.
