Ingredients You’ll Need

This Cheddar Sausage Breakfast Casserole recipe calls for simple, familiar ingredients that come together beautifully. When I shop for this, I like picking fresh bell peppers and green onions to brighten up the dish with a bit of crunch and color.

• Pork sausage: Use a good-quality sausage for rich flavor; I often go with a mild or sweet sausage, but spicy varieties work too if you want a little kick.
• Eggs: The star of the dish, make sure they’re fresh for the best texture.
• Sour cream: Adds creaminess—light or regular both work fine depending on your preference.
• Milk: Just a splash to make the egg mixture tender and fluffy.
• Kosher salt: Enhances all the flavors without overpowering.
• Ground black pepper: Provides a gentle heat and balances the richness.
• Green onions: These freshen up the casserole with their mild onion flavor.
• Green bell pepper: Adds sweetness and a bit of crunch; dice it small for even cooking.
• Red bell pepper: I love the color contrast it gives, plus a slightly sweeter note than the green.
• Shredded cheddar cheese: Sharp or mild cheddar is up to you, but cheddar’s meltability and tang make this casserole super comforting.

Variations

I like to keep my Cheddar Sausage Breakfast Casserole Recipe pretty classic, but over time I’ve played around with some tasty twists. Feel free to customize it to your taste or dietary needs—you’ll find that this recipe is super flexible!

• Vegetarian version: Swap the sausage for sautéed mushrooms or a plant-based sausage alternative—I’ve had friends rave at brunch when I do this.
• Spicy twist: Add a diced jalapeño or some hot sauce to the egg mixture if you like a little heat in your morning meal.
• Cheese swap: Try pepper jack, mozzarella, or even a bit of feta for a different flavor vibe.
• Make it gluten-free: It’s naturally gluten-free, just be sure your sausage has no fillers or seasoning with gluten.

How to Make Cheddar Sausage Breakfast Casserole Recipe

Step 1: Preheat and Prep Your Pan

First things first, preheat your oven to 350°F. Then grab a 9×13 inch baking dish and give it a good spray with cooking oil. I like to use a generous coat here so nothing sticks and the casserole slides out easily after baking—a simple step that makes a big difference.

Step 2: Mix the Egg Mixture

In a large mixing bowl, whisk together your eggs, sour cream, and milk until it’s just combined. Then add the shredded cheddar cheese, salt, and pepper. I use my electric mixer on low speed here just to blend everything without overbeating, which helps keep the texture tender and not rubbery.

Step 3: Cook the Sausage

Heat a large skillet over medium heat and add your pork sausage. Break it up with a wooden spoon as it cooks, and keep stirring until it’s browned all the way through. Once it’s cooked, drain most of the grease—too much oil can make the casserole soggy—and dump the sausage straight into the egg mixture bowl. The sausage carries that great flavor into every bite.

Step 4: Sauté the Veggies

Using the same skillet you cooked the sausage in (because why dirty another dish?), toss in your diced green and red bell peppers along with the chopped green onions. Sauté them for about 2 to 3 minutes until they soften a bit but still have some crunch—this adds a lovely texture contrast. Then add them to your egg and sausage mixture and stir everything together gently.

Step 5: Bake to Perfection

Pour the whole mixture into your prepared baking dish and spread it out evenly. Pop it in the oven and let it bake for 35 to 50 minutes. You’ll know it’s done when the edges are set and the center still jiggles just a little—this means it will firm up perfectly as it cools. Don’t rush this step because patience really pays off with a creamy, custardy texture.

How to Serve Cheddar Sausage Breakfast Casserole Recipe

Garnishes

I love topping my casserole with fresh chopped parsley or a sprinkle of extra shredded cheddar for eye appeal. Sometimes I add a dollop of sour cream or a few slices of ripe avocado to bring a creamy freshness that cuts through the richness beautifully.

Side Dishes

This casserole is pretty hearty on its own, but I like pairing it with a simple green salad or some fresh fruit on the side to lighten things up. For weekends or special brunches, crispy hash browns or toasted sourdough rounds work perfectly too.

Creative Ways to Present

On holidays, I sometimes bake this casserole in individual ramekins to serve personalized portions—they look so cute and save everyone from the “who gets the last piece” debate! Another fun idea is layering it with sliced tomatoes on top before baking for a pop of color and fresh flavor.

Make Ahead and Storage

Storing Leftovers

Leftover breakfast casserole? Score! I usually cover mine tightly with plastic wrap and store it in the fridge, where it keeps beautifully for 3 to 4 days. I’ve found the flavors actually deepen after a day or two, which is a happy surprise.

Freezing

I’ve frozen this casserole a couple of times by tightly wrapping portions in foil and tucking them into freezer bags. It thaws well overnight in the fridge and reheats like a dream, making it a perfect option for busy mornings.

Reheating

When I reheat leftovers, I pop a slice into the microwave for about 90 seconds, covering it with a damp paper towel to keep it moist. Alternatively, 10 minutes in a 350°F oven works nicely if you have more time and want crispy edges again.
