Ingredients You’ll Need
This Cheddar Biscuit Breakfast Casserole keeps things simple yet spectacular – every ingredient is selected for maximum impact, whether it’s lending richness, color, or that classic morning aroma that fills your kitchen. Here’s a quick rundown of what makes this casserole sing and a few tips for best results.
- Refrigerated biscuit dough: This shortcut yields a soft, fluffy base and soaks up all the savory flavors as it bakes – just cut each biscuit into 1-inch pieces for the perfect bite.
- Butter: A little melted butter in the skillet adds richness and helps the veggies cook gently without sticking.
- Breakfast sausage (pork or turkey): This is where you get most of your flavor – choose your favorite variety or swap in turkey for a lighter option.
- Onion: Diced onion adds a savory-sweet undertone that melds seamlessly into every forkful.
- Red bell pepper: Not only does bell pepper bring a pop of color, but it also adds mild sweetness and a little crunch.
- Large eggs: The foundation of your custard – use fresh eggs for the fluffiest result.
- Whole milk: Opt for whole milk for a creamy texture; lower-fat milk works in a pinch but won’t be quite as rich.
- Salt and black pepper: These basics are key to seasoning your egg mixture just right.
- Garlic powder: One small spoonful adds savory depth without overpowering the other flavors.
- Paprika (optional): A sprinkle of paprika lends subtle smokiness and beautiful color to the eggs.
- Shredded sharp cheddar cheese: Go for sharp cheddar if you can; it melts perfectly and packs a punch of flavor atop your casserole.
- Chopped fresh chives or parsley (garnish, optional): These give a fresh, lively finish to every serving – sprinkle generously just before serving.
How to Make Cheddar Biscuit Breakfast Casserole
Step 1: Preheat and Prep Your Dish
Get started by preheating your oven to 350°F – you want a hot oven ready to bake your Cheddar Biscuit Breakfast Casserole to golden perfection. Lightly grease a 9×13-inch baking dish with baking spray or a thin swipe of butter to encourage easy serving later.
Step 2: Sauté the Vegetables and Sausage
Melt a tablespoon of butter in a large skillet over medium heat. Toss in your diced onions and red bell peppers, sautéing for 3 to 4 minutes until they just begin to soften and the kitchen smells amazing. Add your breakfast sausage and cook, breaking it up with a spoon, until browned and no longer pink. Drain off any excess fat and set this savory mixture aside.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, whole milk, salt, black pepper, garlic powder, and a pinch of paprika if you want a hint of smokiness. Mix until everything is well combined and your eggs are a creamy golden color – this liquid gold brings the entire casserole together.
Step 4: Assemble the Casserole
Now for the fun part! Scatter the pieces of biscuit dough evenly across the bottom of your prepared baking dish. Spoon the cooked sausage and vegetable mixture over the biscuit bits, spreading everything out for even bites. Pour your egg mixture over the top, making sure it seeps into all the nooks and crannies. Finish by showering the top with plenty of shredded cheddar cheese.
Step 5: Bake Until Golden and Set
Slide your casserole into the oven and bake for 35 to 40 minutes. You’ll know it’s done when the center is set, the cheese is bubbly, and the top is gorgeously golden. For best results, let your Cheddar Biscuit Breakfast Casserole rest for 5 to 10 minutes before slicing – this helps everything set up for picture-perfect squares. Sprinkle with fresh chives or parsley just before serving for that final flourish.
How to Serve Cheddar Biscuit Breakfast Casserole

Garnishes
A finishing handful of fresh chopped chives or parsley brightens up this hearty casserole and gives it a fresh, restaurant-worthy look. If you like a little heat, a few sliced jalapeños or a dash of hot sauce on top can add zing without overpowering those classic breakfast flavors.
Side Dishes
The Cheddar Biscuit Breakfast Casserole is filling all on its own, but it truly shines when paired with simple sides. Try it alongside a crisp green salad tossed with a bright vinaigrette, a bowl of fresh fruit, or a serving of roasted potatoes. For celebratory brunches, a mimosa or a strong cup of coffee ties it all together.
Creative Ways to Present
If you’re hosting guests or looking to jazz things up, cut the casserole into neat squares and layer them on a platter with toothpicks for a buffet-style brunch. Or, scoop portions into individual ramekins for a personalized, upscale touch. Add a garnish station with toppings like extra cheese, salsa, or avocado for a fun, interactive twist.
Make Ahead and Storage
Storing Leftovers
Leftover Cheddar Biscuit Breakfast Casserole keeps beautifully in the fridge. Transfer cooled slices to an airtight container and store them for up to 4 days. The flavors deepen overnight, making tomorrow’s breakfast just as irresistible.
Freezing
This casserole is a dream for make-ahead meal planners! Once completely cooled, wrap portions tightly in plastic wrap, then foil, and stash in the freezer for up to 2 months. Thaw overnight in the fridge before reheating for best results – it’s a true breakfast lifesaver for busy mornings.
Reheating
To reheat, pop individual servings in the microwave for about a minute, or cover the whole dish with foil and warm it in a 350°F oven until heated through. Adding a sprinkle of fresh cheese or herbs after reheating restores that just-baked flavor and appeal.
FAQs
Can I add other mix-ins to the Cheddar Biscuit Breakfast Casserole?
Absolutely! This casserole loves a little creativity. Try folding in cooked bacon, wilted spinach, diced jalapeños, or even shredded hashbrowns for a personalized spin. Just keep the total volume similar so the eggs set nicely.
Can I make Cheddar Biscuit Breakfast Casserole the night before?
Definitely. You can prep all the components ahead and store them separately, then assemble and bake in the morning. For ultimate ease, you can assemble the whole casserole, cover tightly, and refrigerate overnight. Pop it in the oven when you wake up – just allow for a few extra minutes baking time straight from the fridge.
Do I have to use sharp cheddar, or can other cheeses work in this breakfast casserole?
Sharp cheddar gives the classic flavor, but feel free to swap in Monterey Jack, Colby, or pepper jack for a little variety. Mixing in a bit of mozzarella makes the top extra gooey if you like a super melty finish.
Is it okay to use homemade biscuit dough instead of refrigerated?
Of course! If you have a favorite homemade biscuit dough, just cut it into small pieces and proceed as instructed. You’ll end up with a more rustic finish but even more brag-worthy flavor.
How can I tell when my Cheddar Biscuit Breakfast Casserole is fully cooked?
Look for the center to be set (not jiggly when gently shaken) and the top to be golden brown. If you insert a knife in the center and it comes out mostly clean (a few moist crumbs are fine), it’s ready to serve after a brief rest.
Final Thoughts
If you’re craving a breakfast that’s as comforting as it is easy, you can’t go wrong with Cheddar Biscuit Breakfast Casserole. It’s full of crowd-pleasing flavors and couldn’t be simpler to whip up, even on a busy morning.
