Easy Sausage Gravy Casserole with Flaky Biscuits
This sausage gravy casserole turns classic biscuits and gravy into a single, fuss-free baking dish. The biscuits soak up the creamy, peppery gravy while the top gets golden and flaky, so you get the best of both worlds without standing over the stove.
It works for a quick weeknight dinner or a lazy weekend breakfast, and you only need one skillet and a baking dish to pull it off.
What Makes This Casserole So Good
The biscuits bake right in the sausage gravy instead of being served alongside it, which means every bite carries that rich, peppery flavor. You avoid the mess of making a separate batch of stovetop gravy while juggling a hot pan of biscuits.
Because the casserole holds together in neat squares, it’s easy to serve a crowd without anyone fighting over the last biscuit. The edges crisp up just enough to give you a little texture contrast against the soft, creamy middle.
Ingredients
- 1 lb breakfast sausage: mild or hot, whatever your family prefers
- 2 tbsp unsalted butter: helps the flour cook out and adds a little richness
- 2 tbsp all-purpose flour: builds the body of the gravy
- 2 cups whole milk: lower-fat milk makes a thinner gravy, so whole is best here
- ½ tsp kosher salt: adjust if your sausage is already salty
- ¾ tsp black pepper: this gives the gravy its peppery bite, so don’t skimp
- 1 can (16.3 oz) refrigerated flaky biscuits (8 count): the large, layered kind like Grands
- 1 tsp chopped fresh sage or ½ tsp dried (optional): adds a warm, earthy note
Variations / Substitutions
- Turkey sausage: brown it in a little extra oil or butter since it’s leaner, and the gravy will still be plenty creamy
- Add veggies: sauté half a diced onion and a chopped bell pepper with the sausage for a heartier casserole
- Cheese: sprinkle a cup of shredded cheddar on top of the gravy just before baking for a gooey finish
- Gluten-free: use a 1:1 gluten-free flour blend and your favorite GF refrigerated biscuit dough; the bake time stays the same

How to Make Sausage Gravy Casserole
Step 1: Brown the Sausage
Preheat the oven to 350°F (175°C). In a large oven-safe skillet or regular skillet, cook the 1 lb sausage over medium-high heat, breaking it into crumbles, until no pink remains, about 6 minutes. If you’re adding any vegetables like onion or pepper, toss them in during the last 3 minutes so they soften without burning.
The sausage should have a few deeply browned bits stuck to the bottom of the pan. Those little crusty pieces are where a lot of the flavor lives, so don’t wipe them out when you move on to the next step.
Step 2: Make the Sausage Gravy
Reduce the heat to medium-low and add the 2 tbsp butter. Once it melts, sprinkle the 2 tbsp flour over the sausage and stir constantly for about 1 minute to cook the raw flour taste away. Slowly pour in the 2 cups milk while stirring, then add the salt and pepper. Keep stirring until the gravy thickens and gently bubbles around the edges, roughly 3 to 4 minutes.
You’ll know it’s ready when the back of a spoon leaves a clean trail through the gravy. If it looks too thick, splash in a couple extra tablespoons of milk and stir until it loosens.
This gravy is what the biscuits will bake in, so you want it pourable but not watery. A thicker gravy at this stage gives you the creamy texture you expect after baking.
Step 3: Assemble the Casserole
If your skillet isn’t oven-safe, transfer the gravy to a greased 9×13-inch baking dish. Open the can of biscuits and separate them. Cut each biscuit into quarters, then scatter the pieces evenly over the warm gravy, pressing a few down slightly so they nestle in but still peek out.
Don’t crowd the biscuits too tightly. Leaving a little space between the pieces helps the hot gravy bubble up around them and lets the tops brown properly.
Step 4: Bake and Serve
Slide the dish onto the middle rack and bake until the biscuits are deep golden brown on top and the gravy is bubbling hard around the edges, about 30 minutes. If you’re unsure, poke a biscuit in the center to check it’s no longer doughy.
Let the casserole rest for 5 minutes before you cut into it. Run a spatula around the edges, slice into generous squares, and serve piping hot.
Tips for the Best Sausage Gravy Casserole
- Don’t overbake. The biscuits will keep cooking a little from the hot gravy after you pull it out, so take it from the oven as soon as the tops are richly colored to keep the inside tender.
- Use whole milk. The fat content helps the gravy stay silky and prevents it from breaking or turning watery in the oven.
- If you like extra black pepper, add a pinch on top right before serving. The heat perks up the richness of the sausage.
Storing and Reheating Leftovers
- Refrigerate: cover the casserole and store in the fridge for up to 3 days. The biscuits will soften as they sit, but it still tastes great.
- Reheating: warm individual portions in the microwave for 1 to 2 minutes, or reheat the whole dish covered in a 300°F oven for about 15 minutes until heated through.
What to Serve with Sausage Gravy Casserole
A simple green salad with a lemon vinaigrette balances the richness of the gravy and keeps the plate from feeling too heavy. For a fresh side, sliced tomatoes with salt or a quick fruit salad work well. If you want to lean into the comfort-food vibe, roasted asparagus or steamed green beans with a little butter round out the meal.
Frequently Asked Questions
Can I use homemade biscuit dough instead of canned?
Yes, drop biscuits or rolled biscuit dough both work. Keep an eye on the bake time since homemade doughs can brown faster, and check for doneness by looking for a dry, cooked-through center around the 25-minute mark.
Can I make this casserole ahead of time?
Assemble the dish fully, cover it, and refrigerate overnight. Add 8 to 10 minutes to the bake time, and check that the center is hot before serving.
My gravy looks too thin before I add the biscuits. Will it thicken in the oven?
A little extra moisture is okay because the biscuits absorb some of the liquid as they bake. If the gravy is extremely runny, let it simmer for another minute on the stove to tighten up before assembling.
Can I freeze the baked casserole?
Yes, cool it completely, wrap it tightly, and freeze for up to 2 months. Thaw overnight in the fridge and reheat covered in a 300°F oven until warmed through.
