Cheddar Breakfast Sausage Casserole Recipe

There’s something irresistibly comforting about a breakfast casserole that’s loaded with savory sausage, melty cheddar, and fluffy biscuits. This Cheddar Breakfast Sausage Casserole Recipe is one of my go-to dishes when I want a hearty, crowd-pleasing meal that practically makes itself in the oven. It’s the kind of breakfast that fills the kitchen with cozy aromas and makes everyone linger around the table.

Ingredients You’ll Need

These ingredients come together beautifully to create a hearty casserole that’s both cheesy and savory, with just the right veggies to brighten things up. I always recommend fresh bell peppers and scallions for that pop of color and flavor.

• Breakfast sausage: Choose your favorite brand or type, spicy or mild works – I like to get a quality, well-seasoned sausage for the best flavor.
• Biscuits (canned): These act as the crust and soak up all the flavors; it’s a nice shortcut that keeps things simple and delicious.
• Bell pepper (red or orange): Adds sweetness and crunch; I usually seed and dice it finely so it cooks evenly.
• Scallions: These green onions offer a mild oniony kick without overwhelming the dish.
• Cheddar cheese: Sharp cheddar melts beautifully and gives the casserole that irresistible cheesy top layer.
• Large eggs: They bind everything together and create a lovely, fluffy texture.
• Milk: Just enough to give the eggs a creamy richness without making the casserole soggy.
• Fine sea salt: Essential for seasoning the egg mixture evenly.
• Black pepper: Freshly cracked gives it a nice kick – don’t be shy here.

Variations

I love mixing things up depending on the season or what’s in my fridge. This Cheddar Breakfast Sausage Casserole Recipe is endlessly adaptable, so don’t be afraid to get creative and make it your own.

• Vegetable Swaps: I’ve swapped bell peppers for mushrooms, spinach, or even sun-dried tomatoes – all delicious variations depending on what you’re craving.
• Cheese Choices: Switching out the cheddar for pepper jack or gouda changes the flavor profile beautifully. I’ve found mixing cheeses adds extra creaminess.
• Make it Spicy: Adding a pinch of crushed red pepper flakes to the egg mixture or choosing a spicy sausage gave my family a fun, zesty twist they loved.
• Gluten-Free Option: Try using gluten-free biscuits or a crustless version by omitting the biscuits altogether and adding extra eggs.

How to Make Cheddar Breakfast Sausage Casserole Recipe

Step 1: Brown the Sausage to Perfection

Start by cooking the breakfast sausage in a skillet over medium-high heat. You want to get a nice golden brown on it without overcooking – this takes about 7 to 10 minutes. Drain any excess grease if you’d like, but a little fat helps keep the casserole moist and flavorful.

Step 2: Create the Biscuit Base

Grease your 9×13-inch baking dish, then arrange the canned biscuits evenly on the bottom. Press them out gently with your hands so they form a consistent layer. I like this because it acts like a soft, buttery crust that soaks up all the savory juices as it bakes.

Step 3: Layer with Sausage, Veggies, and Cheese

Spread the cooked sausage evenly over the biscuit layer, then sprinkle diced bell pepper and sliced scallions on top. Finally, cover everything with a generous layer of shredded cheddar cheese. This layering makes sure you get little bites of everything throughout the casserole – it’s pure comfort food magic.

Step 4: Whisk and Pour the Egg Mixture

In a separate bowl, whisk together the eggs, milk, sea salt, and freshly cracked black pepper. Pour this mixture evenly over the layered ingredients in the pan. This helps bind everything together into that perfect fluffy, cheesy, sausage-filled delight.

Step 5: Bake and Enjoy

Bake the casserole at 350°F for 40 to 50 minutes, until the center is puffed and the eggs are fully set. You’ll notice the cheese bubbling and a golden crust around the edges when it’s done. Let it cool for just a few minutes before serving — patience pays off.

How to Serve Cheddar Breakfast Sausage Casserole Recipe

Garnishes

I usually top my slices with a sprinkle of fresh chopped parsley or a little extra sliced scallions for a fresh, vibrant finish. Sometimes a dollop of sour cream or a drizzle of hot sauce adds a nice tangy kick that my family can’t get enough of.

Side Dishes

Pair this casserole with a simple green salad or fresh fruit to add balance. I love serving it alongside roasted breakfast potatoes or crispy bacon to make a full brunch spread that feels extra special.

Creative Ways to Present

For holiday mornings, I’ve turned this casserole into individual portions using muffin tins – they bake faster and look super cute as finger food. Also, layering it in a cast-iron skillet adds a rustic charm when serving guests.

Make Ahead and Storage

Storing Leftovers

Cool the casserole completely, then cover and store leftovers in an airtight container in the fridge for up to 3 days. I find that slicing it into portions before storing makes reheating a breeze.

Freezing

This casserole freezes really well! I usually wrap individual slices tightly in plastic wrap and foil before popping them in the freezer. They keep well for up to 2 months and thaw quickly overnight in the fridge.

Reheating

Reheat leftovers in the oven at 325°F for about 15-20 minutes until warmed through. This keeps the biscuit base crisp and the cheese melty — microwave works in a pinch but can make edges a bit soggy.
