Christmas morning feels even more special when the kitchen smells like warm biscuits, savory sausage, and melted cheese. This Christmas Morning Sausage Biscuit Casserole is pure comfort food: filling, easy to share, and simple enough to make while the coffee brews. I love that it turns familiar breakfast favorites into one golden, satisfying dish.

The casserole brings together breakfast sausage, refrigerated biscuit dough, eggs, and 2% milk. Garlic powder, onion powder, paprika, salt, and black pepper season the egg mixture, while Monterey Jack melts over the top. Each bite is savory and tender, with fluffy biscuit pieces and a mild, creamy cheese flavor. Add green onions for a fresh finish if you like.

Best of all, the method is easy to follow. Brown the sausage, cut the biscuits into quarters, and layer them in a greased baking dish. Then pour over the seasoned egg mixture, add the cheese, and bake until the eggs set and the biscuits turn golden. From start to finish, the recipe takes about 45 minutes, with 15 minutes of prep and 30 minutes of cooking.

This Christmas Morning Sausage Biscuit Casserole serves eight, so it works well for holiday breakfast, a relaxed weekend brunch, or a potluck. It is hearty enough to serve on its own, yet it also pairs nicely with fruit or a fresh salad. Make it for a chilly morning when everyone is ready to gather around the table.

Breakfast Sausage Tips

Choose a breakfast sausage you enjoy eating on its own, since its seasoning shapes the flavor of the casserole. Mild sausage keeps the dish family-friendly, while hot sausage adds a little heat. For the best texture, break the sausage into small, even crumbles as it cooks over medium-high heat. Cook it until no pink remains, then drain off the excess fat before adding it to the biscuits. That small step helps prevent a greasy casserole and lets the egg mixture set nicely.

Options for Substitutions

• Breakfast sausage: Use turkey breakfast sausage for a lighter option, or choose hot sausage for more spice. Cook it fully and drain it before layering.
• Refrigerated biscuit dough: Use a similar amount of another refrigerated biscuit brand. Biscuit sizes can vary, so cut each biscuit into quarters and spread the pieces evenly.
• Milk: Whole milk will make the egg mixture richer. You can also use an unsweetened, unflavored dairy-free milk, though the final texture may differ.
• Monterey Jack cheese: Substitute cheddar, Colby Jack, or a mild Mexican-style cheese blend. For even melting, shred the cheese yourself if convenient.
• Seasonings: Swap the paprika for a pinch of cayenne if you want a little heat. You can also adjust the garlic powder and onion powder to suit your taste.
• Green onions: Leave them off, or finish the casserole with chopped parsley or chives. These are optional garnishes, so the casserole works without them.

Watch Out for These Mistakes

First, do not skip draining the cooked sausage. Excess fat can collect in the bottom of the baking dish and make the biscuits greasy. After browning the sausage, drain it well before layering it over the biscuit pieces.

Next, spread the quartered biscuits across the pan instead of piling them in one spot. Even spacing helps the egg mixture reach the dough and lets the casserole bake more evenly. Also, pour the egg mixture over the whole dish, not just the center.

Keep an eye on the top as it bakes. If the cheese or biscuits brown too quickly, cover the dish loosely with foil. You can also cover it at the start, then remove the foil for the last 5 to 10 minutes so the top can turn golden.

Finally, check the center before taking the casserole out of the oven. The eggs should be set, and the biscuits should look golden. If the center still seems wet, give it a few more minutes. Let the casserole rest briefly before cutting so the slices hold together better.

Storage Instructions

Store: Let leftovers cool, then place them in an airtight container and refrigerate within two hours of serving. Enjoy them within 3 to 4 days. For easier reheating, store individual portions separately.

Freeze: Once cooled, wrap individual portions tightly or place them in freezer-safe containers. Freeze for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating when possible.

Reheat: For the microwave, place one portion on a microwave-safe plate and heat in short intervals until hot throughout. For the stovetop, warm a portion in a covered skillet over low heat with a small splash of water, if needed, until heated through. Avoid high heat, which can dry out the eggs and biscuits. Reheat leftovers until steaming hot.

Step-by-Step Instructions

Step 1: Heat the Oven and Prepare the Dish

Heat the oven to 350°F. Grease a 9×13-inch baking dish with cooking spray so the casserole lifts out more easily after baking.

Step 2: Brown and Drain the Sausage

Set a large skillet over medium-high heat. Add the breakfast sausage and break it into small crumbles as it cooks. Continue cooking until no pink remains, then carefully drain off the excess fat.

Step 3: Layer the Biscuits and Sausage

Cut each refrigerated biscuit into quarters. Scatter the pieces evenly across the prepared baking dish, then spread the cooked sausage over them. Try to distribute both layers from edge to edge.

Step 4: Add the Seasoned Egg Mixture and Cheese

Whisk the eggs and milk with the garlic powder, onion powder, paprika, salt, and black pepper. Pour the mixture evenly over the biscuits and sausage. Sprinkle the shredded Monterey Jack cheese over the top.

Step 5: Bake Until Set and Golden

Bake for 30 to 35 minutes, until the eggs are set in the center, the biscuits are golden, and the cheese is bubbly. If the top browns too fast, cover the dish with foil. Alternatively, cover it from the start and remove the foil for the final 5 to 10 minutes.

Step 6: Rest, Garnish, and Serve

Let the casserole rest briefly before serving. If you like, sprinkle chopped green onions over the top. Cut into portions and serve warm.
