Ingredients You’ll Need
Don’t let the straightforward list fool you—each ingredient plays a vital role in building layers of flavor, texture, and warmth in this dish. The right combination makes the difference between an ordinary breakfast and a beloved tradition.
- Refrigerated biscuits: These provide the fluffy, buttery base that soaks up all the savory goodness.
- Large eggs: Eggs hold everything together and add that rich, creamy texture.
- Shredded cheddar cheese: Cheese adds a perfect melty, sharp finish on top.
- Breakfast sausage: The seasoned sausage brings a savory punch and meaty depth.
- Milk: Milk lightens the egg mixture to keep the casserole tender and moist.
- Salt: Essential for enhancing natural flavors throughout the dish.
- Black pepper: Adds just the right amount of spice to lift the flavors.
How to Make Breakfast Biscuit Casserole Recipe
Step 1: Preheat and Prepare the Sausage
First things first, set your oven to 350°F (175°C) so it’s ready when your casserole is assembled. Cook the breakfast sausage in a skillet over medium heat until it’s nicely browned and cooked through, then drain off the excess grease. This step ensures your sausage is juicy and full of flavor without making the casserole greasy.
Step 2: Whisk the Eggs and Milk
In a mixing bowl, whisk together the six large eggs, one cup of milk, salt, and black pepper. This egg mixture is going to soak into the biscuit pieces and create a custard-like center that’s rich and tender. The seasoning here is key for balancing the richness of the sausage and cheese.
Step 3: Prepare the Biscuit Base
Cut the can of refrigerated biscuits into quarters, which helps them absorb the liquid egg mixture evenly. Spread these biscuit pieces evenly in a greased baking dish, forming a soft, layered foundation for the casserole.
Step 4: Layer the Sausage and Pour the Egg Mixture
Sprinkle the cooked sausage evenly over the biscuits, making sure every bite will have a bit of that savory goodness. Next, pour the egg and milk mixture over the sausage and biscuit layers—this step binds everything together as it bakes.
Step 5: Add Cheese and Bake
Finally, sprinkle a generous cup of shredded cheddar cheese on top to create a glorious golden crust. Bake the concoction for 25 to 30 minutes until the eggs are fully set and the top turns a beautiful golden brown. The cheese will be melted and bubbly, adding that irresistible gooey finish.
How to Serve Breakfast Biscuit Casserole Recipe
Garnishes
To elevate your Breakfast Biscuit Casserole Recipe, add fresh garnishes like chopped green onions, a sprinkle of freshly chopped parsley, or even a dollop of sour cream. These bright accents cut through the richness and add a welcoming pop of color.
Side Dishes
This casserole pairs wonderfully with sides like crisp fruit salad, roasted potatoes, or even a simple mixed greens salad. Adding fresh or lightly cooked vegetables balances out the hearty casserole and rounds out your meal perfectly.
Creative Ways to Present
Try serving this casserole in individual ramekins for a fancy brunch presentation or add a drizzle of hot sauce or a side of homemade salsa to spice things up. You can even layer in veggies like bell peppers or mushrooms before baking for a colorful twist that’s as nutritious as it is delicious.
Make Ahead and Storage
Storing Leftovers
Leftover Breakfast Biscuit Casserole Recipe keeps well in an airtight container in the fridge for up to three days. Simply cover it tightly to maintain moisture and prevent it from absorbing other fridge odors.
Freezing
This casserole also freezes beautifully for up to two months. After baking, let it cool completely, then wrap individual slices or the whole dish tightly in plastic wrap and foil for best results. It’s perfect for quick breakfasts on busy mornings.
Reheating
To reheat, pop portions into a preheated oven at 325°F (165°C) for about 15 minutes until warmed through. Cover with foil to prevent drying out, or microwave slices covered with a damp paper towel for a quicker option, though the oven will keep the texture more delightful.
FAQs
Can I use different types of cheese in the Breakfast Biscuit Casserole Recipe?
Absolutely! While cheddar is classic, feel free to experiment with pepper jack for a spicy kick, mozzarella for gooey meltiness, or Swiss for a nuttier flavor. Each cheese will bring its own unique touch.
Is it possible to make this recipe vegetarian?
Yes! Simply swap out the breakfast sausage with plant-based sausage alternatives or add sautéed vegetables like mushrooms, spinach, and bell peppers to keep the hearty texture without meat.
Can I prepare this casserole the night before?
Definitely. Assemble the casserole, cover it tightly, and refrigerate overnight. When ready, bake it directly from the fridge, adding a few minutes to the baking time to ensure it’s cooked through.
What can I use if I don’t have refrigerated biscuits?
You can substitute with homemade biscuit dough, crescent roll dough, or even cubed day-old bread for a bread pudding-like texture. Each will give a slightly different outcome but still delicious.
How do I know when the casserole is fully cooked?
The best indicator is that the eggs are set firmly in the center and the top is a golden brown. You can also insert a knife or toothpick in the center; it should come out clean without any runny egg.
