How To Make Biscuits and Gravy Breakfast Casserole
This recipe is all about layering flavors and textures for a show-stopper breakfast bake. You’ll start by cooking and seasoning your sausage and veggies, whisking together a silky custard, then building everything in a greased baking dish. Finally, a generous sprinkle of cheddar seals the deal before a golden-brown bake. Follow these detailed steps to nail each part:
1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.
2. Open the package of refrigerated biscuit dough, separate each biscuit, then cut into quarters. Arrange the pieces on a plate and set aside.
3. In a large skillet over medium heat, add the breakfast sausage. Cook, breaking it apart with a spatula, until browned and fully cooked (about 5–7 minutes). Drain any excess grease if necessary for a less oily bake.
4. Add the diced onion and green bell pepper to the skillet with the sausage. Sauté for an additional 2–3 minutes until the vegetables soften and the onion becomes translucent.
5. In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, black pepper, and hot sauce (if using). Whisk until the custard is smooth and combined.
6. Layer the quartered biscuits evenly in the greased baking dish. Evenly distribute the sausage and vegetable mixture over the biscuits for balanced bites.
7. Pour the egg and milk mixture over the sausage and biscuits, ensuring every piece is well coated in the custard.
8. Sprinkle the shredded cheddar cheese over the top of the casserole to create a golden, bubbling crust.
9. Bake in the preheated oven for 30–35 minutes, or until the casserole is set and the top is golden brown.
10. Once done, remove from the oven and allow it to cool for a few minutes so the custard firms up.
11. Garnish with fresh parsley if desired, then cut into squares and serve warm for maximum comfort.

Whether you’re hosting a brunch or fueling a busy morning, these serving ideas will elevate your breakfast casserole into a full spread. Mix and match sides and toppings to keep things fresh and exciting.

Tips For Perfect Biscuits and Gravy Breakfast Casserole
Nailing this breakfast bake is all about timing and tweaks. Make sure each layer is properly seasoned and every component is prepped before assembly. A little planning—like prepping veggies ahead or mixing the custard in one bowl—keeps the process smooth. Don’t skip draining any excess sausage grease, as it helps the biscuits stay light instead of soggy. And remember, this dish is endlessly adaptable, so have fun experimenting with flavors or making it fit your schedule.
- This casserole can be prepared the night before; just cover and refrigerate it before baking the next morning.
- Feel free to customize the recipe with your favorite vegetables or different types of cheese.
- For a spicier kick, consider adding jalapeños or pepper jack cheese.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
How To Store It
Once you have leftovers (or want to prep ahead), proper storage keeps your casserole tasting fresh and delicious. Follow these steps to maintain texture and flavor:
- Refrigerate in an airtight container: Transfer cooled casserole pieces into an airtight container and refrigerate for up to 3 days to maintain moisture and taste.
- Freeze baked casserole: After baking and cooling completely, wrap the entire dish or individual portions tightly in heavy-duty foil or plastic wrap. Freeze for up to 2 months; thaw overnight before reheating.
- Freeze unbaked casserole: Assemble the casserole, then cover tightly with foil or plastic wrap. Freeze for up to 2 months. When ready, bake from frozen at 350°F, adding 10–15 minutes to the baking time.
- Reheat properly: Warm refrigerated portions in a 325°F oven for 10–15 minutes, or microwave single servings for 1–2 minutes until heated through, ensuring the custard is warmed evenly.
Frequently Asked Questions
Here are some quick answers to common questions about this breakfast casserole:
- How long does it take to prepare and bake this Biscuits and Gravy Breakfast Casserole?
It takes about 15–20 minutes to prepare—separating and cutting the biscuits, cooking the sausage and veggies, and whisking the egg mixture—and then 30–35 minutes to bake until golden and set.
- Can I assemble this casserole the night before and bake it in the morning?
Yes. Follow steps 1–7, cover the unbaked dish tightly with foil or plastic wrap, and refrigerate overnight. In the morning, remove the cover, let it sit at room temperature for 15 minutes, then sprinkle on the cheese and bake at 350°F for 30–35 minutes.
- How can I tell when the casserole is fully cooked?
The edges should be golden brown, the center should no longer jiggle, and a knife inserted into the middle should come out clean or with just a few moist crumbs.
- What are good substitutions for the ingredients if I have dietary restrictions?
For a gluten-free version, use certified gluten-free biscuit dough and verify your sausage and spices are gluten-free. For lower fat, swap breakfast sausage for turkey sausage and use skim or plant-based milk. For a vegetarian option, replace sausage with meatless crumbles and add extra veggies.
- How do I store and reheat leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for 1–2 minutes or cover with foil and warm in a 325°F oven for 10–15 minutes.
- Can I freeze the casserole, and what’s the best method?
Yes. For best results, bake the casserole first, let it cool completely, then wrap tightly in foil or plastic freezer wrap and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat at 325°F for 20–25 minutes. You can also freeze it unbaked—assemble, wrap, and freeze—and bake from frozen, adding about 10–15 minutes to the bake time.
- What variations can I try to change up the flavors?
Swap cheddar for pepper jack, Swiss, or mozzarella; stir in diced jalapeños or hot sauce for heat; add cooked crumbled bacon or ham; or mix in spinach, mushrooms, or sun-dried tomatoes for extra veggie boost.
- Is it necessary to drain the sausage grease, and why?
Draining excess grease after browning the sausage prevents the casserole from becoming too oily and helps the biscuits bake up with a light, fluffy texture rather than turning soggy.
