Ingredients You’ll Need

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

1 pound sausage (breakfast sausage, Italian, or spicy)
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)

Let’s Get Started

Preheat your oven to 375°F. Lightly grease a 9×9-inch baking dish or similar-sized casserole dish to prevent sticking.
In a large skillet over medium heat, cook the sausage, breaking it apart with a spoon. Cook for 6–8 minutes until browned and fully cooked through. Drain excess grease if needed.
If using diced onions or bell peppers, add them to the skillet during the last 2–3 minutes of cooking so they soften slightly. If using spinach, stir it in at the very end just until wilted.
If using bread cubes, spread them evenly in the bottom of the prepared baking dish. This creates a heartier base and absorbs the egg mixture beautifully.
Evenly distribute the cooked sausage (and vegetables, if used) over the bread layer or directly into the dish if skipping the bread.
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and smoked paprika until fully combined and slightly frothy.
Pour the egg mixture evenly over the sausage and bread. Gently press down any bread pieces to ensure they soak up the liquid.
Sprinkle the shredded cheddar cheese evenly over the top.
Bake uncovered for 30–35 minutes, or until the center is set and a knife inserted in the middle comes out clean. The top should be lightly golden and slightly puffed.
Let the casserole rest for 5–10 minutes before slicing. This allows it to firm up and makes serving easier.

Servings and Pairing

This casserole serves about 6 people. Pair it with fresh fruit, yogurt, or roasted breakfast potatoes. It’s also perfect alongside coffee and a simple green salad for brunch.

Variations

Swap cheddar for Monterey Jack, Swiss, or pepper jack.
Use turkey or chicken sausage for a leaner option.
Add mushrooms or zucchini for extra vegetables.
Make it low-carb by omitting the bread cubes.
Add a pinch of red pepper flakes for extra heat.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm in the oven at 325°F until heated through.

This casserole freezes well. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

How do I know when it’s fully cooked?

Can I use a different milk?

Yes, whole milk, 2%, or even dairy-free milk alternatives work well.

Can I double the recipe?

Absolutely. Use a 9×13-inch baking dish and increase the baking time by about 5–10 minutes if needed.
