Biscuits and Gravy Breakfast Casserole

By Callie

Introduction

I grew up eating biscuits and gravy as two separate things on a plate – a split biscuit on one side, a ladle of sausage gravy on the other. It’s one of those meals that always felt like home, especially on cold Saturday mornings when my mom would have the kitchen smelling like browned sausage and warm butter before I even got out of bed. So when I started thinking about how to turn that into something I could make for a crowd without standing over the stove serving individual plates, the casserole version just made sense.

The first time I made this biscuits and gravy breakfast casserole, I was hosting my in-laws for a Sunday morning visit and needed something that could feed eight people without me being stuck in the kitchen the entire time. I cut up a tube of refrigerated biscuits, layered them with browned sausage, eggs, cheese, and a quick peppered gravy, and slid the whole thing in the oven. Forty-five minutes later I pulled out a golden, bubbly dish that looked like a magazine cover and tasted like every good Southern breakfast I’d ever had, all in one pan.

My father-in-law went back for seconds before anyone else had finished their first serving. Emily asked if we could have it “every single weekend.” And my husband stood in the kitchen eating straight from the baking dish after everyone left. This recipe has been in our regular rotation ever since, and it’s become my go-to for holiday mornings, overnight guests, and any time I want a big, hearty breakfast without the hassle of cooking multiple dishes. If you love this kind of warm, savory morning meal, you should also check out my Hashbrown Breakfast Casserole – it’s another crowd-pleasing bake with the same set-it-and-forget-it ease.

Why You Will Like This Biscuits and Gravy Breakfast Casserole

• Only 10 minutes of hands-on prep – Brown the sausage, cut up the biscuits, whisk the eggs, and layer everything in the dish. The oven handles the rest while you pour yourself a cup of coffee and actually sit down.
• Feeds a crowd from one pan – This makes 8 generous servings out of a single 9×13-inch baking dish. It’s the kind of recipe that feeds a full table without requiring you to cook multiple things at once.
• All the flavors of a Southern classic in casserole form – Fluffy biscuit pieces that soak up that rich, peppered gravy, savory sausage in every bite, melted cheddar cheese holding it all together, and eggs that set into a custard-like layer throughout. It’s biscuits and gravy, but better.
• Make-ahead friendly – Assemble the whole thing the night before, cover it, and refrigerate. In the morning, just pop it in the oven. This is a lifesaver for holiday mornings and overnight guests when you don’t want to be scrambling at 7 a.m.
• Kid-friendly and adult-approved – The flavors are comforting and familiar, not spicy or fussy. Emily and her friends love it, and the adults at our table always go back for more. It hits that sweet spot where everyone at the table is happy.
• High in protein – Between the sausage, eggs, cheese, and milk, this casserole keeps you full all morning. It’s the kind of breakfast where you don’t start thinking about lunch until well past noon.
• Easily customizable – Swap the sausage type (mild, spicy, maple), change the cheese, add vegetables, adjust the spice level – the base recipe is flexible enough to make it your own every time.
• Perfect for potlucks and gatherings – Bake it, bring the whole dish, and serve at room temperature or keep warm in a low oven. It travels well and reheats beautifully.

Biscuits and Gravy Breakfast Casserole Ingredients

• 1 package refrigerated biscuits (8-count) – I use Pillsbury Grands because they puff up nicely and have a buttery flavor that works perfectly in a casserole. You’ll cut each biscuit into four pieces so the chunks distribute evenly across the dish and create pockets that soak up the gravy and egg mixture. Homemade biscuits work too if you want to go from scratch, but you’ll need to par-bake them about halfway first so they don’t end up doughy in the center.
• 6 eggs – The eggs get whisked with milk and poured over the layers, creating a custard-like base that sets during baking and holds everything together. Use room temperature eggs if you can – they blend more smoothly with the milk and cook more evenly.
• 1 package (2.3 oz) peppered gravy mix – This is the shortcut that makes the whole recipe come together quickly. The peppered gravy adds that classic peppery, savory flavor you’d get at a Southern diner. Prepare it according to the package directions and let it thicken slightly before drizzling over the casserole.
• 1 lb sausage – Mild, spicy, or maple-flavored all work here. Breakfast sausage in the tube form (not links) is easiest because you can crumble it directly into the skillet. Brown it over medium heat until there’s no pink left, breaking it into small pieces as it cooks. Drain the grease before adding it to the casserole – this step is important for preventing a greasy finished dish.
• 1 cup shredded cheddar cheese – Sharp cheddar gives you the most flavor, but medium cheddar, Colby Jack, or Monterey Jack all melt nicely and taste great. Shred your own from a block if you can. Pre-shredded cheese has an anti-caking coating that prevents it from melting as smoothly.
• 1/2 cup milk – Whole milk makes the egg mixture richer and creamier. It gets whisked with the eggs and poured over the casserole layers, seeping down between the biscuit pieces and creating that set, custard-like texture when it bakes.
• Salt and pepper, to taste – Season the egg mixture with a good pinch of salt and several cracks of black pepper. Keep in mind that the sausage and peppered gravy already bring a lot of seasoning, so taste the sausage before you go heavy on the salt.

Callie’s Kitchen Note: I tested this recipe with three different sausage flavors side by side. Mild is the safest crowd-pleaser, especially if kids are eating. Spicy adds a nice kick that balances beautifully with the creamy gravy – that’s my personal pick. Maple sausage was surprisingly great too. The subtle sweetness against the peppery gravy and sharp cheddar created this sweet-savory contrast that Emily said was “like breakfast candy.” Her words, not mine.

How To Make Biscuits and Gravy Breakfast Casserole

Prepping the Oven and Baking Dish

Preheat your oven to 350 degrees F. Grease a 9×13-inch baking dish with non-stick cooking spray or a thin layer of butter. Glass or ceramic baking dishes both work well here. Glass distributes heat more evenly, which helps the biscuit pieces cook through without burning on the bottom.

Browning the Sausage

Place the sausage in a large skillet over medium heat. Break it into small crumbles with a wooden spoon or spatula as it cooks. You want the pieces bite-sized, roughly the same size as the biscuit chunks so every scoop of casserole gets a good distribution of both.

Cook until browned and no longer pink, about 6-8 minutes. This is where the flavor develops – let the sausage get a little golden and caramelized on the edges. That browning (the Maillard reaction) is what gives the finished casserole its deep, savory backbone.

Drain the excess grease by tilting the skillet and spooning it off, or transfer the sausage to a paper towel-lined plate. Don’t skip this step. Leftover grease will pool in the bottom of your casserole and make the biscuits soggy and oily instead of golden and tender.

Assembling the Casserole

Cut each biscuit into four pieces and scatter them evenly across the bottom of the greased baking dish. They don’t need to be perfectly arranged – a casual, even distribution works best because the pieces will puff up during baking and fill in the gaps.

Spread the drained, crumbled sausage over the biscuit layer. Then sprinkle the shredded cheddar cheese evenly on top of the sausage.

In a medium bowl, whisk together the eggs, milk, salt, and pepper until smooth. Pour the egg mixture evenly over the cheese layer, letting it seep down between the biscuit pieces. You’ll see it settle into all the gaps – that’s exactly what you want.

Callie’s Kitchen Note: I learned that the order of layers matters more than I originally thought. I tried putting the cheese on the very bottom once (under the biscuits) thinking it would create a cheesy crust, but it just stuck to the pan and burned. Biscuits on the bottom, sausage next, cheese on top of the sausage, then the egg mixture poured over – that’s the order that works every time.

Preparing and Adding the Gravy

Prepare the peppered gravy mix according to the package instructions. Let it simmer and thicken for a minute or two beyond what the package says – you want it slightly thicker than pourable so it sits on top of the casserole rather than running straight to the bottom. Drizzle the gravy evenly over the top of the assembled casserole.

Baking

Bake uncovered at 350 degrees F for 35-40 minutes. You’ll know it’s done when the biscuit pieces on top are golden brown, the eggs are set (no jiggling liquid in the center when you shake the pan gently), and the cheese is bubbly. Start checking at 35 minutes since every oven runs a little differently.

Remove from the oven and let it rest for about 5 minutes before serving. This resting time lets the egg layer firm up slightly so the casserole holds together better when you scoop it out. Cut into squares or just serve with a big spoon.

Common Mistakes To Avoid

Not draining the sausage grease. This is the single biggest mistake that leads to a greasy, heavy casserole. Sausage renders a lot of fat as it cooks, and if that fat goes into the baking dish, it pools under the biscuits and prevents them from crisping. Take an extra minute to drain it.

Making the gravy too thin. If the gravy is watery when you pour it over the casserole, it will sink straight to the bottom and make the biscuit layer soggy. Let the gravy cook down until it’s thick enough to coat the back of a spoon before adding it. It’ll thin out slightly as it bakes, so err on the thicker side.

Callie’s Kitchen Note: The first time I made this for a group, I used homemade biscuits that I’d rolled and cut fresh. They looked beautiful going in, but the centers came out completely raw and doughy. The issue was that homemade biscuit dough is thicker and denser than refrigerated biscuits, so it needs more time to cook through. If you use homemade, par-bake them for about 8-10 minutes first, then cut them up and proceed with the recipe. The refrigerated biscuits from a tube don’t need this step because they’re thinner and designed to cook quickly.

Overbaking past 40 minutes. The biscuit pieces on the edges will start to dry out and get tough if you leave the casserole in too long. The center should be set but still slightly soft and custardy, not dry and crumbly. Check at 35 minutes and pull it when the top is golden.

Cutting the biscuit pieces too small. If you cut them into tiny bits, they dissolve into the egg mixture and you lose the biscuit texture entirely. Quartering each biscuit (four pieces) gives you chunks that are big enough to hold their shape and puff up while still cooking through.

Storage and Reheating

Refrigerator storage: Let the casserole cool to room temperature, then cover tightly with foil or transfer portions to an airtight container. Refrigerate for up to 4 days. The flavors actually blend together even more overnight, so next-day leftovers are really good.

Freezer storage: Cut the cooled casserole into individual portions and wrap each one tightly in plastic wrap, then in aluminum foil. Store in a labeled freezer bag for up to 3 months. Individually wrapping means you can pull out exactly what you need each morning without thawing the whole batch. This is one of my best meal prep tricks – I’ll make a full casserole on Sunday and have hot breakfasts all week.

Oven reheating (best method): Place a portion in an oven-safe dish, cover loosely with foil, and bake at 350 degrees F for 10-15 minutes until heated through. The oven brings back the golden top and keeps the biscuit texture intact.

Microwave reheating: Place a portion on a microwave-safe plate, cover with a damp paper towel, and heat in 30-second intervals until hot. The damp towel adds moisture back so the biscuits don’t dry out. This won’t give you a crispy top, but it’s the fastest option.

Air fryer reheating: If you have an air fryer, set it to 300 degrees F and reheat a portion for about 5 minutes. This actually crisps up the biscuit pieces on top and gives you a result that’s closer to fresh-baked than any other method.

Biscuits and Gravy Breakfast Casserole Variations

Spicy Southern Version – Use hot breakfast sausage and add 1/2 teaspoon of cayenne pepper to the egg mixture. Swap the cheddar for pepper jack cheese and stir a diced jalapeno into the sausage while it browns. Top the finished casserole with a drizzle of hot sauce. This version has real heat and it’s my husband’s pick every time.

Tex-Mex Biscuits and Gravy Casserole – Add taco seasoning to the sausage as it browns. Use a blend of cheddar and pepper jack, add diced green chiles to the egg mixture, and top the finished casserole with fresh pico de gallo, sour cream, and sliced avocado. It’s a totally different flavor profile that works surprisingly well with the biscuit base.

Veggie-Loaded Version – Swap the sausage for a cup each of sauteed mushrooms, diced bell peppers, and fresh baby spinach. Saute the vegetables until tender and any liquid has cooked off, then layer them where the sausage would go. Add a handful of diced tomatoes on top before baking. This is a great option for vegetarian guests or Meatless Monday breakfasts.

Extra Cheesy Version – Double the cheese to 2 cups and use a blend of sharp cheddar and Colby Jack. Add an extra 1/2 cup sprinkled on top during the last 5 minutes of baking so it melts into a golden, bubbly crust. Stir 2 tablespoons of cream cheese into the warm gravy before pouring it over the casserole for extra richness.

Callie’s Kitchen Note: I tried a “breakfast for dinner” version where I added crumbled bacon on top of the sausage layer and used maple sausage as the base. Then I drizzled a tiny bit of real maple syrup over the finished casserole right before serving. The combination of salty sausage, smoky bacon, peppery gravy, and that hint of maple sweetness was honestly one of the best things I’ve made this year. Emily said it tasted “like a pancake house but better,” which I’m taking as a win.

Holiday Brunch Version – Add crumbled cooked bacon to the sausage layer, stir fresh chopped sage and rosemary into the egg mixture, and use a blend of gruyere and white cheddar instead of regular cheddar. Garnish with fresh herbs before serving. This version feels more elevated and special-occasion-worthy without being any harder to make.

Gluten-Free Version – Swap the refrigerated biscuits for a gluten-free biscuit mix (or homemade gluten-free biscuits, par-baked) and use a gluten-free gravy mix. Everything else stays the same. I’ve made this for a friend with celiac and she said it was one of the few gluten-free casseroles she’s actually enjoyed.

Serving Suggestions

Classic breakfast spread: Serve big scoops of this casserole alongside a bowl of fresh fruit and a simple green salad with a light vinaigrette. The fruit and greens balance out the richness of the sausage and gravy, and the whole spread looks beautiful on the table.

For a hearty brunch buffet: Set the baking dish on a trivet and serve it right from the pan alongside scrambled eggs, crispy bacon, hash browns, and a fruit platter. This casserole is the star of any brunch table, but having a couple of lighter options alongside it gives guests variety.

Individual portions for a fancier presentation: Scoop portions into individual ramekins or small oven-safe dishes before baking. This looks polished and each guest gets their own perfectly portioned serving. It also prevents the “who’s going to take the last piece” standoff.

Garnish ideas: A sprinkle of chopped fresh parsley or chives adds a pop of green color against the golden casserole. A light dusting of paprika or a crack of extra black pepper on top before serving also looks nice and adds a touch more flavor.

Beverage pairings: Hot coffee is the natural match – something strong like a dark roast or a rich latte stands up well to the savory, hearty flavors. For brunch gatherings, mimosas or a Bloody Mary bar keeps things festive. Fresh-squeezed orange juice or a vanilla chai latte are great non-alcoholic options that complement the warm, comforting vibe.

For holiday mornings: This casserole is perfect for Christmas morning, Easter brunch, or Thanksgiving weekend breakfast because you can assemble it the night before and bake it while presents are being opened or guests are arriving. No early-morning cooking required. For more on the science behind how sausage browning creates flavor through the Maillard reaction, Serious Eats has a great explanation of why browning matters.
