Ingredients You’ll Need
This Cheddar Biscuit Breakfast Casserole relies on a handful of staple ingredients, each one pulling its weight to create magic in a pan. Nothing fancy required — just reliable, flavorful basics coming together for pure comfort.
- Biscuit Dough: Refrigerated biscuit dough provides that tender, fluffy base and saves precious morning prep time.
- Breakfast Sausage: Crumbled sausage adds heartiness and rich, savory flavor throughout the casserole.
- Eggs: Eggs create the classic custard that binds every layer, offering fluffiness and richness.
- Whole Milk: Using whole milk ensures the eggs stay extra creamy without being too heavy.
- Sharp Cheddar Cheese: Sharp cheddar melts beautifully and brings a bold, tangy edge.
- Mozzarella Cheese: Mozzarella offers stretch and gooeyness, balancing the flavor of cheddar.
- Garlic Powder: Just a hint gives the dish irresistible savory depth.
- Onion Powder: Lends gentle sweetness and umami to the overall flavor profile.
- Salt and Black Pepper: Essential for rounding out all the flavors — don’t skip the seasoning!
- Chopped Green Onions or Chives (optional): Sprinkled on top for fresh color and a light, zippy bite.
How to Make Cheddar Biscuit Breakfast Casserole
Step 1: Prepare the Oven and Baking Dish
Start by preheating your oven to 350°F (175°C), and lightly grease a 9×13-inch baking dish. This will prevent sticking and help those golden edges form on your Cheddar Biscuit Breakfast Casserole. A little butter or nonstick spray works wonders!
Step 2: Cook the Sausage
In a medium skillet over medium heat, crumble and cook the breakfast sausage until it’s browned and cooked through. Take a moment to break up any big pieces with your spatula for even distribution. Once cooked, drain off any excess grease and set the sausage aside — your kitchen should already smell like a diner in the best way.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, whole milk, garlic powder, onion powder, salt, and black pepper. Aim for a smooth, well-blended mixture so every bite of casserole gets that perfect custardy texture and flavor.
Step 4: Layer the Biscuits and Sausage
Cut the refrigerated biscuit dough into quarters, then layer the pieces evenly across the bottom of your prepared baking dish. Scatter the cooked sausage over the biscuit pieces, making sure every section gets a bit of both for maximum flavor.
Step 5: Pour and Top
Next, pour your egg mixture gently and evenly over the biscuits and sausage, tilting the pan a little if needed to get full coverage. Sprinkle the shredded cheddar and mozzarella cheeses over the top, creating that irresistible cheesy blanket that defines Cheddar Biscuit Breakfast Casserole.
Step 6: Bake and Finish
Bake the casserole for 35 to 40 minutes, or until the center is set and the top is deeply golden. If you’re unsure, a knife inserted near the center should come out clean. Let the casserole rest for about 5 minutes before slicing — it’ll be easier to serve and the flavors will settle beautifully.
How to Serve Cheddar Biscuit Breakfast Casserole
Garnishes
A sprinkle of chopped green onions or chives is the perfect finishing touch, offering a pop of color and a gentle bite that wakes up the whole dish. For extra flair, a dusting of cracked black pepper or a shake of smoked paprika is lovely, but not required — this casserole can truly stand on its own.
Side Dishes
Pair your Cheddar Biscuit Breakfast Casserole with a light, fresh salad of mixed greens, some sweet seasonal fruit, or roasted breakfast potatoes. Since the casserole is so hearty and cheesy, these crisp and juicy sides create the ideal brunch spread without overwhelming anyone’s plate.
Creative Ways to Present
For gatherings, try slicing the casserole into squares and arranging them on a platter with toothpicks for easy serving. Or, use cookie cutters for fun shapes — perfect for kids and festive occasions! You can also serve it family-style straight from the baking dish, letting guests help themselves to generous scoops.
Make Ahead and Storage
Storing Leftovers
Leftover Cheddar Biscuit Breakfast Casserole keeps beautifully for up to three days in the refrigerator. Simply cover the dish tightly with foil or transfer slices to an airtight container for easy grab-and-go breakfasts.
Freezing
This casserole is a freezer-friendly winner! Once cooled completely, wrap individual slices or the whole casserole tightly in plastic wrap and then foil. Freeze for up to two months. When ready to eat, thaw in the refrigerator overnight before reheating.
Reheating
To reheat, place slices on a baking sheet and warm in a 350°F oven until hot and melty, about 10 to 15 minutes. For quick mornings, the microwave will do the trick — just heat in short bursts to avoid overcooking the eggs and biscuits.
FAQs
Can I assemble Cheddar Biscuit Breakfast Casserole the night before?
Absolutely! Prepare the casserole up to the point of baking, cover it, and refrigerate overnight. In the morning, let it sit at room temperature while the oven preheats, then bake as directed for a simple, fresh-out-of-the-oven meal.
Can I substitute bacon or ham for the sausage?
Definitely. Cooked and crumbled bacon or chopped ham both work wonderfully in place of sausage, offering their own unique flavor versions of this cheesy breakfast delight. Just be sure to use the same total amount of meat for best results.
What’s the best way to tell when the casserole is done?
The casserole is finished baking when the center is no longer jiggly and a knife inserted comes out clean. The top should be golden and the cheese bubbling — irresistible signs that it’s ready to slice!
Can I make this Cheddar Biscuit Breakfast Casserole gluten-free?
Yes! Simply swap in your favorite gluten-free biscuit dough and check that your sausage and seasonings are gluten-free as well. The rest of the recipe remains deliciously the same.
How do I prevent soggy biscuits at the bottom?
To keep the biscuit base tender but not soggy, make sure the sausage is well drained and that you distribute the egg mixture evenly over the top. Using a preheated oven and the right bake time help deliver those fluffy, perfectly baked results.
