12 eggs

¼ cup of milk

2 cups of shredded cheddar cheese

-

-
A wooden spoon for stirring
Having everything ready will make the cooking process seamless and enjoyable!
Cook the beef sausage
In a large skillet over medium heat, add your beef sausage. Cook it until browned, breaking it into smaller pieces with a wooden spoon. This usually takes about 5-7 minutes. Make sure to drain most of the grease afterward—nobody wants a greasy breakfast casserole! Once drained, add the sausage to your mixing bowl where the magic will begin to happen.
Whisk together the egg mixture
Next, in that same mixing bowl, crack open the 12 eggs. Add in the sour cream, milk, kosher salt, and black pepper. Grab your whisk (or use an electric mixer if you prefer) and mix everything together until just combined. Remember, you don’t want to over-mix; a little air left in the mixture will help your casserole rise nicely as it bakes!
Combine all components in a dish
Once your egg mixture is ready, it’s time to take the veggies to the skillet. Sauté the diced green and red bell peppers along with the chopped green onions for about 2-3 minutes until they soften a bit. Add those to the bowl with the eggs and sausage, and stir everything together until combined. Then, pour this delicious mixture into your greased 9x13-inch dish.
Bake to perfection
Preheat your oven to 350 degrees Fahrenheit and then pop your casserole in for about 35 to 50 minutes. You’ll know it’s done when the edges are set but the center still jiggles a little—this ensures it's perfectly fluffy. If you want more precision, inserting a toothpick should come out clean when the casserole is ready.
This breakfast casserole is best enjoyed fresh but can also be stored in the fridge for 3-4 days. Trust me, leftovers are just as delightful! You can easily reheat them in the microwave, making busy mornings a breeze. Happy cooking!

Cooking tips and notes for Breakfast Casserole
How to prevent a soggy casserole
To ensure your breakfast casserole comes out perfectly fluffy, avoid adding too many wet ingredients. If you're incorporating fresh veggies, consider sautéing them first to remove excess moisture. For a firmer texture, you can also use day-old bread instead of fresh. This will absorb the egg mixture better and prevent that soggy bottom!
Storage tips for leftovers
If you have any delicious breakfast casserole leftover, store it in an airtight container in the fridge for up to 3-4 days. When you're ready to enjoy it again, simply reheat a portion in the microwave or oven until it's warmed through. For long-term storage, consider freezing portions—just wrap them tightly in plastic wrap before placing them in a freezer-safe bag. This way, you’ll have a quick and easy breakfast ready to go whenever hunger strikes!

Serving suggestions for Breakfast Casserole
Pairing with fresh fruit or yogurt
To elevate your breakfast casserole, consider serving it alongside a colorful array of fresh fruit or a dollop of creamy yogurt. The sweetness of seasonal berries or sliced bananas perfectly balances the savory flavors of the casserole. A side of Greek yogurt can add a delightful creaminess, plus a protein boost to keep you energized throughout the day. For a touch of sweetness, drizzle some honey over your yogurt and sprinkle with granola—it's a wholesome way to complement your breakfast spread!
Complementing with hot sauce or salsa
Looking for a little kick? Enhance your breakfast casserole experience by adding your favorite hot sauce or a fresh salsa. The spiciness can really bring out the flavors of the sausage and cheese, making every bite more thrilling. Traditional salsa pairs well, but feel free to get creative with fruit salsas like mango or pineapple for a unique twist! A splash of acidity from lime juice can also brighten up the dish and make your breakfast a flavorful adventure.
