Ingredients and Preparation

Eggs
The heart of this dish, eggs provide structure and protein. When beaten with sour cream and milk, they become light and fluffy.

Pork Sausage
It brings depth and savory richness. You can swap it with turkey sausage, ground chicken, or even vegetarian crumbles for a plant-based version.

Sour Cream and Milk
These add creaminess to the egg mixture. Sour cream helps stabilize the eggs and enhances the richness, while milk keeps the texture soft.

Cheddar Cheese
Melts beautifully into the mix, offering a sharp flavor. Feel free to experiment with Swiss, pepper jack, or dairy-free cheese substitutes.

Green and Red Bell Peppers
They offer a sweet crunch and vibrant color. You can sub them with zucchini, mushrooms, or spinach.

Green Onions
Add a mild, fresh onion flavor. Regular diced onions or chives can work too.

Salt and Black Pepper
Simple seasonings that bring all the flavors together.

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 light coat of oil.

Step 2 In a large mixing bowl, crack the eggs and whisk them together with sour cream, milk, salt, pepper, and shredded cheese. You don’t need to overmix—just enough until it looks uniform and slightly frothy.

Step 3 Heat a large skillet over medium heat and cook the sausage, breaking it into crumbles as it browns. This should take about 5–7 minutes. Once cooked, drain off most of the grease and set aside.

Step 4 In the same skillet, sauté the bell peppers and green onions for about 2–3 minutes until they’re slightly softened. This step boosts flavor and ensures they cook evenly in the casserole.

Step 5 Add the sausage and sautéed veggies into the egg mixture. Stir gently to combine, making sure everything is well-distributed.

Step 6 Pour the mixture into the prepared baking dish and smooth out the top. Bake uncovered for 35–50 minutes. You’ll know it’s done when the edges are set and the center is slightly jiggly—it will continue cooking as it cools.

Step 7 Let it cool for 10 minutes before slicing. This resting time helps it firm up and makes serving easier.

Beginner Tips and Notes

• If your vegetables start to brown too quickly, reduce the heat and stir more frequently.
• Use pre-chopped vegetables or frozen mixed bell peppers to save time.
• Don’t worry if the top looks slightly golden—it adds flavor and texture.
• No hand mixer? Just use a whisk and some elbow grease to combine your ingredients.
• Make cleanup easier by lining your baking dish with parchment paper.

Serving Suggestions

This easy breakfast casserole pairs wonderfully with a side of fresh fruit, a slice of whole-grain toast, or a dollop of Greek yogurt. Want to take it up a notch? Serve it with a light tomato salsa or a drizzle of hot sauce.

Leftovers store beautifully. Keep them in an airtight container in the fridge for up to four days. Reheat individual slices in the microwave for 1–2 minutes or in the oven at 300°F until warmed through.
