Instructions
Step 1: Prepare the Biscuit Base
- Preheat your oven to 350°F and grease a 9x13-inch baking dish thoroughly
- Cut each biscuit into quarters and arrange them evenly in the prepared baking dish
- Cook the breakfast sausage in a large skillet over medium heat until browned and crumbled
- Sprinkle the cooked sausage over the biscuit pieces, creating an even layer
Step 2: Create the Egg Mixture
- In a large mixing bowl, whisk together eggs, milk, salt, and pepper until well combined
- Pour the egg mixture evenly over the biscuits and sausage in the baking dish
- Gently press down any floating biscuit pieces to ensure they absorb the egg mixture
- Sprinkle both cheddar and mozzarella cheeses evenly over the top
Step 3: Bake to Perfection
- Cover the dish with aluminum foil and bake for 25 minutes
- Remove the foil and continue baking for 20-25 minutes until the center is set and top is golden

- Let the casserole rest for 10 minutes before serving to allow it to set properly
Expert Cooking Tips
Temperature Control
Managing your oven temperature correctly is crucial for achieving the perfect texture in your biscuit breakfast casserole. Start with the covered baking method to gently cook the eggs without overcooking the bottom layer.
- Always preheat your oven for at least 15 minutes before baking
- Use an oven thermometer to verify accurate temperature
- Place the baking dish on the center rack for even heat distribution
- Avoid opening the oven door during the first 20 minutes of baking
Ingredient Preparation Tips
- Let refrigerated biscuits sit at room temperature for 15 minutes before cutting for easier handling
- Cook sausage completely and drain excess grease to prevent a greasy casserole
- Use room temperature eggs for better mixing and even cooking
- Shred cheese from a block rather than using pre-shredded for better melting
Make-Ahead Success
- Assemble the casserole completely, cover tightly, and refrigerate overnight
- Add an extra 10-15 minutes to baking time if cooking from cold
- Let the cold casserole sit at room temperature for 30 minutes before baking for more even cooking

Grandma's Secret That Changed Everything
The game-changing secret to the perfect biscuit breakfast casserole lies in the resting technique that most people skip entirely. After assembling your casserole, let it sit for 15 minutes before baking, allowing the biscuits to absorb just enough of the egg mixture while maintaining their structure and creating those coveted layers of flavor that make this biscuit breakfast casserole truly exceptional.
Another crucial secret involves the cheese placement strategy that transforms an ordinary dish into something extraordinary. Instead of mixing all the cheese into the egg mixture, reserve half to sprinkle on top during the final 15 minutes of baking, creating a beautiful golden crust that contrasts perfectly with the tender biscuit breakfast casserole beneath.
FAQ
Does a breakfast casserole have to sit overnight?
No, your biscuit breakfast casserole doesn't require overnight sitting, though it can be assembled ahead for convenience. The casserole can be baked immediately after assembly, but allowing it to rest for 15-30 minutes helps the biscuits absorb the egg mixture for better texture.
Should breakfast casserole be cooked covered or uncovered?
Cook your biscuit breakfast casserole covered for the first 25 minutes to prevent over-browning, then uncover for the final 20-25 minutes to achieve a golden, bubbly top while ensuring the center cooks through completely.
How long should a casserole rest before serving?
Let your finished biscuit breakfast casserole rest for 10-15 minutes after baking to allow the egg mixture to set properly, making it easier to cut clean slices and preventing a runny texture when served.
Do you have to cook canned biscuits all at once?
No, you can use only the biscuits needed for your biscuit breakfast casserole and store the remaining biscuits in the refrigerator for up to their expiration date, making this recipe perfect for smaller families or portion control.
