12 eggs: The fluffy base that binds everything together and provides hearty protein.
1 cup sour cream (light or regular): Adds a luscious creaminess that makes the casserole irresistibly tender.
1/4 cup milk: Helps to lighten the mixture and ensure a soft, moist texture.
1 teaspoon kosher salt: Balances flavors and enhances each ingredient’s natural taste.
1/2 teaspoon ground black pepper: Brings a gentle warmth and subtle kick.
4 green onions: Introduce a mild oniony brightness that refreshes every mouthful.
1/2 green bell pepper (diced): Provides a crisp, sweet crunch and gorgeous green color.
1/2 red bell pepper (diced): Adds sweetness and a lovely pop of red for visual appeal.
2 cups shredded cheddar cheese: The cheesy, golden crown that melts into every corner for richness and irresistible flavor.
Sausage (amount to taste): Browned to perfection, it offers a savory, meaty contrast that makes the casserole truly satisfying.

How to Make Cheesy Breakfast Casserole with Sausage and Bell Peppers Recipe

Step 1: Preheat and Prepare Your Pan

Start by preheating your oven to 350 degrees. Grease a 9×13-inch baking dish with cooking spray to make sure your casserole slides right out with ease after baking. This simple prep gets you ready for the delicious layers to come.

Step 2: Mix the Egg Mixture

In a large bowl, whisk together the 12 eggs, sour cream, milk, shredded cheddar cheese, kosher salt, and black pepper. Use an electric mixer on low speed just until combined — you want the mixture smooth but not over-beaten, so your casserole remains light and tender.

Step 3: Brown the Sausage

Heat a skillet over medium heat, then add your sausage. Cook until it’s beautifully browned and broken into small crumbles, giving the dish that essential savory depth. Drain most of the grease before mixing it into the egg mixture; this keeps the casserole from getting greasy while retaining all the flavor.

Step 4: Sauté the Bell Peppers and Green Onions

Using the same skillet (and the sausage’s delicious drippings), toss in the diced green and red bell peppers along with chopped green onions. Sauté for 2 to 3 minutes just until they soften slightly and release their sweet aromas. This step enhances the texture and brightens the flavor in the final bake.

Step 5: Combine and Bake

Stir the sautéed vegetables into your egg and sausage mixture until well combined. Pour everything into your greased 9×13-inch pan. Bake for 35 to 50 minutes, keeping an eye out for the edges to set and the center to hold a slight jiggle. This is the golden window for creamy, cooked-through perfection without drying out.

Garnishes

Before serving, consider sprinkling freshly chopped parsley or chives over the top for a burst of green color and herbal freshness. A dollop of sour cream or a drizzle of hot sauce can also elevate the flavors and offer guests personalized options.

Side Dishes

This casserole pairs beautifully with crispy hash browns or a fresh fruit salad. The crunchy, cool fruits balance the richness, while a side of buttery toast or English muffins adds a comforting touch to complete your meal.

Creative Ways to Present

Serve the casserole in individual ramekins for a charming brunch presentation or cut it into neat squares on a platter for buffet-style serving. For a fun twist, layer it with sliced avocado or a fresh tomato salsa on top — it makes the dish look even more inviting.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover the casserole tightly and store it in the refrigerator. It stays delicious for about 3 to 4 days, making it perfect for quick breakfasts or snack reheats throughout the week.

Freezing

You can freeze portions of the casserole in airtight containers or freezer bags for up to 2 months. This makes it a fantastic meal prep option for busy mornings or anytime you crave a slice of comfort.

Reheating

To reheat, simply microwave individual portions until warmed through, or place the casserole in a preheated oven at 350 degrees for 15 to 20 minutes. Reheating this way keeps the texture just as delightful as the first time you baked it.

FAQs

Can I use turkey sausage instead of regular sausage?

Absolutely! Turkey sausage is a great leaner alternative that still delivers plenty of savory flavor without the extra fat. Just adjust cooking times if needed to ensure it’s fully cooked.

Can I make this recipe vegetarian?

Yes, simply omit the sausage and add extra bell peppers, diced mushrooms, or even spinach to maintain heartiness and keep it flavorful.

What cheese works best besides cheddar?

Cheddar is classic, but feel free to experiment with Monterey Jack, mozzarella, or even pepper jack for a little added spice and melty goodness.

Is it possible to prepare the casserole the night before?

Definitely! Assemble it, cover it tightly, and keep it refrigerated overnight. Bake it fresh in the morning for a super convenient, time-saving breakfast.

How can I make the casserole less rich?

Use light sour cream or Greek yogurt instead of regular sour cream, and choose low-fat milk. Also, reducing the cheese slightly can help lighten the overall dish.
