Ingredients and Preparation

Eggs – The heart of the dish, eggs bind the casserole and provide protein and richness. They puff up beautifully when baked, creating a light yet hearty texture.

Breakfast sausage – Adds savory depth and a slightly spicy flavor. You can use pork, turkey, or even plant-based sausage.

Cheese – Typically cheddar, for a gooey, melty finish. It also adds saltiness and richness. Swiss, pepper jack, or mozzarella are great swaps depending on your taste.

Sour cream and milk – These create a creamy, custard-like base. Sour cream adds tanginess, while milk keeps the texture light. For dairy-free versions, use plain Greek yogurt and oat milk.

Bell peppers – Red and green peppers bring color, crunch, and a slight sweetness. You can also add mushrooms, spinach, or zucchini.

Green onions – For a mild onion flavor and a fresh finish. Red or yellow onions can be used if that’s what you have on hand.

Salt and black pepper – Basic seasonings to balance and elevate the dish.

Step-by-Step Instructions

Step 1
Preheat your oven to 350°F and grease a 9×13-inch baking dish with cooking spray or a bit of oil to prevent sticking.

Step 2
In a large mixing bowl, combine the eggs, sour cream, milk, cheese, salt, and pepper. Mix until just combined—don’t overbeat, as this can make the eggs rubbery.

Step 3
Heat a skillet over medium heat. Add the sausage and cook it thoroughly, breaking it apart with a wooden spoon into small crumbles. Once browned and cooked through, transfer it to the egg mixture.

Step 4
In the same skillet, sauté your diced bell peppers and green onions for 2–3 minutes until slightly softened but still vibrant. Add these to the bowl as well and stir everything together until well-mixed.

Step 5
Pour the entire mixture into your prepared baking dish. Use a spatula to spread it evenly.

Step 6
Bake for 35 to 50 minutes. The edges should be golden and set, while the center should have a slight jiggle—it will continue to cook as it cools. To check doneness, insert a knife in the center; it should come out clean.

Beginner Tips and Notes

If your Sausage and Egg Breakfast casserole is browning too quickly on top but still jiggly in the center, lightly tent it with foil to prevent over-browning.
Overcooked eggs can become rubbery. To avoid this, keep an eye on the center and pull it from the oven as soon as it’s nearly set.
Don’t skip sautéing the vegetables—it enhances their flavor and prevents excess moisture in your casserole.
Want to prep like a pro? Chop your vegetables and cook your sausage the night before. Store them in separate containers and mix everything together in the morning.
No mixer? No problem. A whisk and some arm power work just fine.

Serving Suggestions

Serve this Sausage and Egg Breakfast casserole with a side of fresh fruit for a balanced breakfast. A dollop of salsa or a drizzle of hot sauce can add a flavor punch.
