Ingredients

Pantry and Refrigerator

• 2 (16.3 oz) cans refrigerated biscuit dough (homestyle or buttermilk; avoid flaky layers for best rise)
• 2 cups pizza sauce (thick, not watery)
• 2 cups shredded low-moisture mozzarella
• 1/2 cup grated Parmesan
• 6 oz pepperoni slices (mini or regular, quartered)
• 1 green bell pepper, diced
• 1 small red onion, thinly sliced
• 1 cup sliced mushrooms (pat dry if wet)
• 2 cloves garlic, minced
• 2 tbsp olive oil

Seasoning

• 1 tsp dried Italian seasoning
• 1/2 tsp crushed red pepper flakes (optional for heat)
• 1/2 tsp kosher salt (adjust to taste)
• Freshly ground black pepper

Finishing Touches

• Fresh basil or parsley, chopped
• Drizzle of olive oil or hot honey (optional)

How to Make Bubble Up Pizza Casserole

1) Preheat and Prep

• Heat oven to 350°F (175°C).
• Grease a 9×13-inch baking dish with olive oil or nonstick spray.

2) Sauté the Veggies

• Warm 2 tbsp olive oil in a skillet over medium heat.
• Add bell pepper, onion, and mushrooms. Cook 4–5 minutes until softened and excess moisture releases.
• Stir in garlic for 30 seconds. Season with a pinch of salt and pepper. Remove from heat.

3) Cut the Biscuits

• Open biscuit cans. Cut each biscuit into quarters (bite-size pieces cook evenly).
• Place pieces in a large bowl.

4) Mix the Base

• Add pizza sauce, Italian seasoning, optional red pepper flakes, half the mozzarella, half the Parmesan, sautéed veggies, and half the pepperoni to the bowl.
• Toss gently to coat every biscuit piece. Make sure no dry spots remain.

5) Assemble

• Spread mixture into the prepared baking dish.
• Top with remaining mozzarella, Parmesan, and pepperoni.

6) Bake

• Bake uncovered for 30–38 minutes, until the top turns golden, cheese bubbles, and a center biscuit tests cooked through.
• If the top browns too quickly, tent loosely with foil during the last 10 minutes.

7) Rest and Finish

• Let casserole rest 5–10 minutes to set.
• Garnish with chopped basil or parsley. Add a drizzle of olive oil or hot honey if you like a sweet-heat finish.

Serving Tips

• Serve with a green salad or garlic-roasted broccoli.
• Offer extra pizza sauce for dipping.

How to Store and Reheat Bubble Up Pizza Casserole

• Cool completely before storing to prevent soggy biscuits.
• Refrigerate: Store in an airtight container for up to 4 days.
• Freeze: Wrap portions tightly and freeze up to 2 months. Thaw overnight in the fridge.
• Reheat:
  • Oven: 350°F for 12–15 minutes (cover with foil).
  • Air fryer: 320°F for 5–8 minutes.
  • Microwave: 60–90 seconds per portion, then crisp in a hot skillet or air fryer if desired.

Benefits of Making This Easy Pizza Casserole

• Weeknight win: Quick assembly and hands-off bake time.
• Budget-smart: Pantry staples plus a few toppings stretch into a full meal.
• Kid-approved: Familiar flavors and cheesy goodness encourage clean plates.
• Party-friendly: Doubles in two pans without extra effort.
• No special skills: Straightforward steps yield consistent results.

Mistakes to Avoid

• Using watery sauce: Thin sauce sogs the biscuits. Stick with thick, spoonable sauce.
• Overloading raw veggies: Too much moisture prevents proper rise. Sauté and drain first.
• Undercooking the center: Test a middle biscuit piece; it should look fluffy and cooked, not doughy.
• Skipping the rest: A short rest settles the casserole and makes cleaner slices.
• Flaky-layer biscuits: They separate too much; choose homestyle or buttermilk.

Variations You Can Try

• Meat Lover’s: Add cooked Italian sausage, crumbled bacon, and pepperoni.
• Veggie Supreme: Use sautéed spinach, olives, peppers, onions, mushrooms, and artichokes.
• BBQ Chicken: Swap half the pizza sauce for BBQ sauce; add cooked shredded chicken, red onion, and smoked Gouda.
• Hawaiian: Add diced ham and pineapple tidbits (pat dry) with mozzarella and a pinch of chili flakes.
• Margherita Style: Use basil, fresh mozzarella pearls (drained), and extra Parmesan; finish with a drizzle of balsamic glaze.
• Gluten-Free: Use gluten-free refrigerated biscuit dough and confirm toppings are GF.
• Lighter Take: Use reduced-fat mozzarella, turkey pepperoni, and bulk up with extra veggies.

FAQ

Can I make this ahead?

Yes. Assemble up to the cheese, cover, and refrigerate for up to 8 hours. Add 5–8 minutes to bake time and watch browning.

Do I need to cook sausage first?

Absolutely. Cook and drain sausage to remove grease before mixing into the casserole.

What if I only have flaky biscuits?

They can work, but layer separation changes the texture. Press pieces together lightly when mixing and bake closer to the longer time.

How do I prevent soggy bottoms?

Use thick sauce, sauté and drain veggies, and bake on the center rack. If needed, bake the last 5 minutes on the lower rack.

Can I use marinara instead of pizza sauce?

Yes—choose a thicker marinara or simmer for a few minutes to reduce.

How do I know it’s done?

Cheese should bubble and the top should brown. Pierce the center; a biscuit piece should look fluffy and not doughy.

Conclusion

This bubble up pizza casserole brings pizza night to the table without rolling dough or juggling multiple pans. It’s cozy, flexible, and seriously satisfying. Keep biscuit dough and sauce on hand, add your favorite toppings, and you’ve got an easy weeknight staple the whole family will love.
