Timing
This Easy Biscuits and Gravy Breakfast Casserole requires approximately 90 minutes total time, which is actually nearly some of faster than traditional layered breakfast casseroles. Here’s the breakdown:
- Prep Time: 20 minutes
- Cooking Time: 45 minutes
- Rest Time: 10 minutes
- Active Working Time: Only 25 minutes (while the oven does the heavy lifting)
The beauty of this timing allows you to start preparation at 8 AM and serve a restaurant-quality breakfast by 9:30 AM, perfect for weekend family gatherings.
Step 1: Prepare Your Foundation
Preheat your oven to 350°F and generously grease a 9×13-inch baking dish. Cut the refrigerated biscuits into quarters and toss them with melted butter in a large bowl. This butter coating ensures each biscuit piece develops a golden, crispy exterior while maintaining a tender interior. Spread the buttered biscuit pieces evenly across the bottom of your prepared dish, creating a sturdy foundation for the layers above.
Step 2: Create the Perfect Sausage Gravy
In a large skillet over medium-high heat, cook the breakfast sausage, breaking it into small, bite-sized crumbles. Cook for 6-8 minutes until no pink remains and the sausage develops beautiful caramelized edges. Sprinkle the flour directly over the cooked sausage and stir continuously for 2 minutes to eliminate the raw flour taste. Gradually whisk in the milk, starting with 1/2 cup and adding the remainder slowly to prevent lumps. Season with garlic powder, onion powder, salt, and black pepper.
Step 3: Build Your Flavor Layers
Pour the hot sausage gravy evenly over the biscuit pieces, ensuring every corner receives adequate coverage. The gravy will naturally settle into the gaps between biscuits, creating pockets of creamy goodness. In a separate bowl, whisk together the beaten eggs and heavy cream until well combined, then pour this mixture over the gravy layer. This egg mixture will set during baking, binding all components together beautifully.
Step 4: Add the Cheese Crown
Sprinkle the shredded cheddar and mozzarella cheeses evenly across the top surface. The combination of sharp cheddar and mild mozzarella creates the perfect balance of flavor intensity and melting properties. Cover the dish tightly with aluminum foil to prevent excessive browning during the initial cooking phase.
Step 5: Bake to Golden Perfection
Bake covered for 30 minutes, then remove the foil and continue baking for an additional 15 minutes until the top is golden brown and the center is set. A knife inserted in the center should come out with just a few moist crumbs. Allow the casserole to rest for 10 minutes before serving – this crucial step allows the layers to firm up for clean, beautiful slices.

Serving Suggestions
Elevate your Easy Biscuits and Gravy Breakfast Casserole presentation with complementary sides that balance the rich, creamy flavors. Fresh fruit salad with berries and citrus segments provides a bright, acidic contrast that cleanses the palate between bites. Crispy hash browns or roasted breakfast potatoes add textural variety and additional heartiness for larger appetites.
For special occasions, consider serving alongside fluffy scrambled eggs with herbs or a light arugula salad dressed with lemon vinaigrette. The peppery greens and bright acidity create an elegant contrast to the comforting casserole. Coffee, fresh orange juice, or herbal teas complete this satisfying breakfast experience perfectly.
Common Mistakes to Avoid
Avoid these frequent pitfalls that can compromise your casserole’s success. Never skip the flour-cooking step when making gravy – raw flour creates an unpleasant chalky taste and poor texture. Ensure your milk is at room temperature before adding it to the sausage mixture to prevent curdling and lumpy gravy.
Overcooking is another common error. Remove the casserole when the center is just set but still slightly jiggly – it will continue cooking during the resting period. Using pre-shredded cheese instead of freshly grated cheese can result in poor melting and a grainy texture due to anti-caking agents. Finally, resist cutting into the casserole immediately after baking; the 10-minute rest period is crucial for proper setting and clean slicing.
Storing Tips for the Recipe
Proper storage extends your casserole’s enjoyment well beyond the initial meal. Refrigerate leftover portions in airtight containers for up to 4 days, ensuring food safety while maintaining optimal texture and flavor. For longer storage, wrap individual portions tightly in plastic wrap, then aluminum foil, and freeze for up to 3 months.
When reheating, cover refrigerated portions with foil and warm in a 325°F oven for 15-20 minutes until heated through. Frozen portions should be thawed overnight in the refrigerator before reheating. Avoid microwave reheating when possible, as it can create uneven heating and compromise the biscuits’ texture.

FAQs
Q: Can I prepare this Easy Biscuits and Gravy Breakfast Casserole the night before?
A: Absolutely! Assemble the entire casserole, cover tightly with plastic wrap and refrigerate overnight. Add an extra 10-15 minutes to the covered baking time since you’ll be starting with a cold dish.
Q: What’s the best way to ensure my gravy doesn’t become lumpy?
A: The key is gradual milk incorporation and constant whisking. Add milk slowly, starting with just 1/2 cup, and whisk continuously. Room temperature milk integrates more smoothly than cold milk.
Q: Can I use homemade biscuits instead of refrigerated ones?
A: Certainly! Use about 12 medium homemade biscuits, baked until just golden, then cut into pieces. Slightly underbaked biscuits work best since they’ll finish cooking in the casserole.
Q: How do I know when the casserole is properly cooked?
A: The center should be set but still slightly jiggly, and a knife inserted in the middle should come out with minimal moist crumbs. The top should be golden brown and the edges should be bubbling gently.
Q: What sides pair best with this breakfast casserole?
A: Fresh fruit, crispy bacon or turkey sausage links, hash browns, and fresh coffee create a well-rounded breakfast spread. The key is balancing the rich casserole with lighter, fresher elements.
