Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 can refrigerated biscuits (about 8 pieces)
1 jar pasta sauce (24 oz / 650 ml)
1 package frozen cooked meatballs (about 32 meatballs)
2 cups shredded mozzarella cheese
1/2 cup grated parmesan cheese
1 teaspoon dried oregano
1 teaspoon garlic powder
1/2 teaspoon black pepper
1 tablespoon olive oil
Directions
Start by preheating your oven to 190°C (375°F). Lightly grease a baking dish with olive oil to prevent sticking and ensure easy cleanup.
Cut each refrigerated biscuit into quarters. Spread the biscuit pieces evenly across the bottom of the baking dish, forming a base layer. This will act as the “bread” portion of your casserole.
Next, arrange the frozen cooked meatballs over the biscuit layer. There’s no need to thaw them beforehand, as they will cook thoroughly in the oven.
Pour the pasta sauce evenly over the meatballs and biscuit pieces, making sure everything is well coated. Sprinkle the garlic powder, oregano, and black pepper over the top to enhance the flavor.
Add the shredded mozzarella cheese generously across the surface, followed by the grated parmesan cheese. This combination creates a rich, golden topping once baked.
Place the casserole in the oven and bake for 30 to 35 minutes, or until the biscuits are cooked through and the cheese is bubbly and slightly golden. If needed, cover loosely with foil halfway through baking to prevent excessive browning.
Remove from the oven and let it rest for about 5 minutes before serving. This allows the casserole to set slightly and makes it easier to portion.
Servings and timing

Variations
You can easily adapt this recipe to suit different preferences. For a spicier version, add a pinch of red pepper flakes or use a spicy pasta sauce. If you enjoy vegetables, consider adding sliced bell peppers, mushrooms, or onions to the casserole.
For a different cheese profile, try mixing in cheddar or provolone along with mozzarella. You can also use homemade meatballs instead of frozen ones for a more personalized touch.
If you want a lighter version, reduce the amount of cheese or opt for a lower-fat alternative. Whole wheat biscuit dough can also be used for a slightly healthier base.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the casserole has cooled completely before storing.
To reheat, place a portion in the microwave and heat for 1 to 2 minutes until warmed through. For better texture, you can reheat it in the oven at 180°C (350°F) for about 10 to 15 minutes.
If you plan to freeze the casserole, wrap it tightly and store it for up to 2 months. Thaw overnight in the refrigerator before reheating.
