The lazy weeknight dinner that tastes like you actually tried.
You know those recipes where you look at the ingredient list and think, that’s it?
This is one of those. And it delivers way more than it has any right to.
Bubble up pizza casserole is essentially all your favorite pizza toppings baked into a bubbling, cheesy casserole dish — using refrigerated biscuit dough that puffs up and soaks in all that saucy, meaty goodness as it cooks. The result is something between a deep dish pizza and a savory bread pudding, and honestly, it’s impossible to stop eating.
I started making this on those nights when delivery felt too expensive, but standing at the stove felt like too much effort. This recipe sits comfortably in neither camp. You dump things into a bowl, pour it into a pan, and 35 minutes later your whole kitchen smells like a pizzeria. 🍕
Keep reading, because there are a few small tricks that take this from pretty good to everyone asking for the recipe.
What You’ll Need
Nothing fancy. You probably have most of this already.
The Dough Base
- 2 cans (16.3 oz each) refrigerated Pillsbury Grands biscuits, cut into quarters
- 1 tablespoon olive oil
The Filling
- 1 lb (450g) Italian sausage, casings removed (or ground beef)
- 1 cup pepperoni slices, halved (plus extra for the top)
- 1 jar (24 oz) marinara or pizza sauce
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried oregano
- 1/4 teaspoon red pepper flakes (optional, but recommended)
- Salt and black pepper to taste
The Cheese Layer
- 2 cups shredded mozzarella cheese
- 1/2 cup shredded Parmesan cheese
Optional Toppings
- 1/2 cup sliced black olives
- 1/2 cup diced bell pepper (any color)
- 1/4 cup sliced banana peppers
- Fresh basil for garnish
Tools You’ll Need
- 9×13 inch baking dish (glass or ceramic)
- Large skillet or frying pan
- Large mixing bowl
- Sharp knife and cutting board
- Wooden spoon or spatula
- Measuring cups and spoons
- Cooking spray or butter for greasing
- Aluminum foil
Pro Tips
1
Quarter the biscuits, don’t halve them. Smaller pieces mean more surface area to absorb the sauce. You get little pockets of fluffy, sauce-soaked dough in every bite instead of big gummy lumps. This is probably the most important step.
2
Don’t skip browning the sausage first. Raw meat thrown directly into the casserole releases too much liquid and makes the whole thing soggy. Brown it, drain it, then mix it in. Ten extra minutes, massive payoff.
3
Reserve some cheese for the last 10 minutes. Add your first layer of cheese, bake covered for 25 minutes, then uncover, add the rest of the cheese and the extra pepperoni, and bake for another 10. You get a deep, bubbly crust on top instead of pale melted cheese. Night and day difference.
4
Let it rest before serving. Give it 5–8 minutes after it comes out of the oven. It sets up, cuts cleaner, and you won’t burn your mouth on molten cheese. Patience is genuinely rewarded here.
5
Coat the biscuit pieces in sauce before baking. Instead of just pouring sauce over the top, toss the biscuit quarters in the sauce mixture in the bowl first. Every single piece gets coated, which means no dry spots lurking at the bottom of the dish.
How to Make Bubble Up Pizza Casserole
- Preheat your oven to 375°F (190°C).Grease your 9×13 baking dish with cooking spray and set it aside.
- Brown the sausage.In a large skillet over medium-high heat, cook the Italian sausage, breaking it up as it cooks. Once fully browned (about 8 minutes), drain the excess fat and remove from heat. Let it cool slightly.
- Quarter the biscuits.Open both cans of biscuit dough and cut each biscuit into 4 pieces using your knife and cutting board. Place all pieces into your large mixing bowl.
- Make the mix.Add the browned sausage, pepperoni, marinara sauce, Italian seasoning, garlic powder, onion powder, oregano, and red pepper flakes to the bowl with the biscuit pieces. Stir everything together until the biscuit pieces are evenly coated. Season with salt and pepper.
- Pour into the baking dish.Transfer the mixture into your prepared 9×13 dish and spread it into an even layer.
- First cheese layer + cover.Sprinkle 1 cup of mozzarella over the top. Cover tightly with aluminum foil. Bake for 25 minutes.
- Finish uncovered.Remove foil, add the remaining mozzarella, Parmesan, and extra pepperoni slices on top. Return to the oven uncovered for 10–12 more minutes, until the cheese is golden and bubbling and the biscuits are cooked through.
- Rest and serve.Let the casserole sit for 5–8 minutes before slicing. Garnish with fresh basil if using. Serve warm.
Substitutions and Variations
This recipe is a blank canvas. Here’s how to make it yours:
| Swap This | For This | Why It Works |
|---|---|---|
| Italian sausage | Ground turkey or chicken sausage | Lighter without losing the savory depth |
| Pillsbury Grands biscuits | Any refrigerated biscuit dough | Smaller biscuits just means more pieces to cut |
| Marinara sauce | Homemade pizza sauce or arrabbiata | Arrabbiata adds a spicy kick 🌶️ |
| Mozzarella | Provolone or a blend of Italian cheeses | Provolone melts beautifully and has more flavor |
| Pepperoni | Salami, ham, or cooked bacon | All hold up well during baking |
| All meat (to go veggie) | Mushrooms, zucchini, roasted red peppers | Sauté them first to remove excess water |
Gluten-free? Use a gluten-free biscuit dough (Bob’s Red Mill makes a solid one) and double-check your sauce label. Everything else is naturally GF.
Dairy-free? Swap the mozzarella for your favorite dairy-free shredded cheese. Violife and Daiya both melt well in a casserole situation.
Make Ahead Tips
Make Ahead
Brown the sausage up to 2 days ahead and store it covered in the fridge. When you’re ready to bake, just assemble everything and go.
Fully assemble, don’t bake. You can mix everything together and pour it into the greased baking dish, then cover tightly with plastic wrap and refrigerate for up to 8 hours. Pull it out 20 minutes before baking to take the chill off, then bake as directed. Add 5 minutes to the covered bake time if it goes in cold.
I wouldn’t recommend assembling more than 8 hours ahead — the biscuit dough starts absorbing too much moisture and loses its puff.

Pair It With
- A simple green salad with Italian dressing (balances the richness perfectly)
- Garlic bread or breadsticks
- Roasted broccoli or zucchini on the side
- A cold beer or a glass of Chianti if you’re feeling fancy
Leftovers and Storage
Good news: leftovers are arguably even better the next day once everything has settled and the flavors have had time to meld.
- Fridge: Store in an airtight container or covered baking dish for up to 4 days.
- Freezer: Portion into individual servings, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: Oven at 350°F for 15–20 minutes is your best option for keeping the biscuit texture intact. Microwave works in a pinch — cover with a damp paper towel and go in 90-second intervals.
Cooking Time Efficiency Tip
While the casserole bakes, use that 35-minute window to throw together a salad, set the table, and pour yourself a drink. This recipe is genuinely hands-off once it goes in the oven, so take advantage of it.
FAQ
Can I use homemade pizza dough instead of canned biscuits?
Technically yes, but the texture will be different. Canned biscuits puff up in a specific way that creates that signature “bubble up” texture. Homemade dough works but tends to be denser. If you go that route, use small torn pieces and expect a slightly chewier result.
My casserole came out soggy. What went wrong?
Two likely culprits: the sausage wasn’t drained well enough (it released too much fat and liquid during baking), or the sauce was too watery. If your marinara is on the thinner side, simmer it for 10 minutes on the stove first to thicken it up before mixing.
How do I know when it’s actually done?
The cheese on top should be golden and bubbling, and if you insert a knife or toothpick into the center, it should come out clean with no raw dough on it. The biscuit pieces in the middle should feel set and springy, not doughy.
Can I double this recipe for a crowd?
Yes, either use two 9×13 pans or one very deep roasting pan. Don’t try to cram a double batch into one standard pan — it won’t cook evenly and the middle will stay raw. Two pans on two racks works well, just rotate them halfway through baking.
Can kids help make this?
This is one of the best kid-friendly cooking projects out there. Cutting biscuit dough into quarters is easy and satisfying, and stirring everything together in a big bowl requires zero skill. Kids who help make dinner almost always eat it more enthusiastically too.
Can I add more vegetables without making it watery?
Yes, with one rule: pre-cook any vegetables that hold a lot of water (mushrooms, zucchini, bell peppers) in a hot skillet first until they’ve released most of their moisture. Pat them dry before adding. Hearty veg like olives or sun-dried tomatoes can go in raw.
Wrapping Up
Bubble up pizza casserole is the kind of recipe that becomes a regular without you even deciding it will. You make it once for a busy Tuesday, and suddenly it’s on the unofficial rotation.
It’s messy in the best way. The biscuits puff and soak and get crispy at the edges. The cheese bubbles. The whole thing looks like it came from somewhere much more effort-intensive than a mixing bowl and a 35-minute bake.
Make it this week. You won’t regret it.
