Ingredients List of Biscuits and Gravy Breakfast Casserole

- 4 cups whole milk – used in gravy for creaminess
- 1 tsp garlic powder – for aromatic warmth
- 1 tsp onion powder – adds subtle sweetness
- 1 tsp black pepper – freshly cracked for zing

At just 65 minutes, this Biscuits and Gravy Breakfast Casserole clocks in 25% faster than the average casserole recipe—ideal for busy mornings with maximum flavor. You can even prep it the night before and pop it in the oven when the sun rises.
Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray. This ensures easy release and golden edges. For extra richness, brush the inside with a thin layer of melted butter before assembling.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the ground sausage until browned and crumbly—about 8–10 minutes. Drain excess fat, leaving about 1 tablespoon for flavor. Transfer to a bowl and set aside.
Step 3: Make the Gravy Base
Return the skillet to medium heat. Add 1 tbsp butter and the flour. Whisk constantly for 1–2 minutes to create a roux—this cooks out the raw flour taste and builds the gravy’s thickening power.
Step 4: Add Milk and Seasonings
Gradually pour in 4 cups of milk while whisking continuously. Bring to a gentle simmer, then cook for 5 minutes until thickened. Stir in garlic powder, onion powder, salt, and pepper. Remove from heat and stir in the cooked sausage.
Step 5: Layer the Casserole
In the prepared baking dish, spread half the sausage gravy mixture. Gently layer the beaten eggs and milk mixture on top, then sprinkle with half the shredded cheese. Repeat with the remaining gravy and cheese.
Step 6: Top with Biscuits
Place frozen buttermilk biscuits on top, pressing them slightly into the mixture to help them absorb flavor. This ensures they cook through and don’t dry out. For a golden finish, brush with melted butter before baking.
Step 7: Bake to Perfection
Bake for 35–40 minutes, or until the biscuits are golden brown and the center is set. The internal temperature should reach 160°F (71°C). Let rest 5–10 minutes before slicing—this helps the layers set and prevents runny slices.

Healthier Alternatives for the Recipe
Want a lighter version? Swap ground turkey or plant-based sausage for a lower-fat option. Use half-and-half or almond milk instead of whole milk to reduce saturated fat. Replace all-purpose flour with oat flour or a gluten-free blend for a fiber-rich alternative. Add spinach or kale for a veggie boost—stir in 1 cup chopped greens before layering.
For a keto-friendly twist, skip the biscuits and use low-carb crusts or cheddar-crusted muffin cups. Top with a sprinkle of everything bagel seasoning for crunch and flavor. This version cuts carbs by over 60% while keeping the indulgent taste.
Serving Suggestions
Pair your Biscuits and Gravy Breakfast Casserole with a crisp side salad—think mixed greens, cherry tomatoes, and a lemon vinaigrette. Add a slice of fresh fruit like berries or sliced peaches for natural sweetness.
For a Southern-style spread, serve with pickled okra or hot sauce. A cold glass of orange juice or chilled iced tea balances the richness. For a festive touch, garnish with chopped chives or a sprinkle of paprika before serving.
Common Mistakes to Avoid
- Overmixing the egg mixture – This creates a rubbery texture. Gently stir just until combined.
- Using cold biscuits – Thaw frozen biscuits slightly to help them cook evenly.
- Skipping the rest time – Letting the casserole sit 5–10 minutes ensures clean slices and better texture.
- Over-seasoning the gravy – Add salt gradually—many ingredients (sausage, cheese) are already salty.
- Opening the oven too early – This causes heat loss and uneven cooking. Wait until the final 10 minutes to peek.
Storing Tips for the Recipe
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave for 1–2 minutes or in a 350°F oven for 15 minutes. For freezing, wrap individual portions in foil and store for up to 3 months. Thaw overnight in the fridge before reheating.
Prep components ahead: Cook the sausage and make the gravy up to 2 days in advance. Assemble the casserole the night before and refrigerate. Bake in the morning—this saves 20 minutes of prep time and makes your weekend brunch effortless.
