Crafting Your Easy Pizza Casserole: Ingredients & Customizations

One of the best aspects of this Upside Down Pizza Casserole is its flexibility. While our recipe provides a fantastic foundation, don’t hesitate to make it your own! Here’s a closer look at the key components and how you can personalize them.

The Hearty Filling: Meats and Vegetables

Our recipe calls for a winning combination of lean ground beef or turkey, savory Italian sausage, and classic pepperoni. This trio delivers a rich and varied flavor profile that mimics a supreme pizza. However, feel free to adjust:

• Meat Variations: You can use all ground beef, all Italian sausage, or even add some cooked ham or crumbled bacon for extra flavor. For a lighter option, stick with ground turkey.
• Vegetable Power: Chopped onion, bell pepper, and sliced mushrooms are foundational, adding texture and earthy notes. But the possibilities don’t end there. Consider adding diced zucchini, spinach, or even some finely chopped carrots for extra nutrients. Jarred sliced olives bring that signature briny pizza touch.
• Flavor Base: A quality pasta sauce is crucial. Choose your favorite brand or even a homemade marinara to set the flavor tone. Minced garlic adds aromatic depth that’s essential for any good Italian-inspired dish.

The Gooey Cheese Factor

No pizza is complete without generous amounts of melted cheese! Shredded mozzarella is the star here, providing that iconic stretchy, gooey texture. Parmesan cheese, sprinkled on top of the crust, adds a salty, nutty bite and helps create that beautiful golden-brown finish.

• Cheese Combos: Experiment with a blend of cheeses! Provolone, Monterey Jack, or even a touch of sharp cheddar can add interesting dimensions.

The Versatile Crust: Homemade or Store-Bought Perfection

The beauty of an upside down casserole is that the “crust” is less about intricate shaping and more about a simple topping. This means you have incredible flexibility when it comes to your dough choice:

• Pizza Dough: A one-pound package of store-bought pizza dough is incredibly convenient and works perfectly. Brands like Pillsbury also offer great options. If you’re feeling ambitious, homemade pizza dough will yield an even more artisanal result.
• Biscuits: For an even quicker and softer crust, canned biscuit dough is an excellent substitute. Simply arrange the biscuits over the filling and bake.
• Crescent Rolls: Similar to biscuits, crescent roll dough can be unrolled and laid over the top for a flaky, buttery crust.

The key here is not to overthink it. Use whatever is most convenient for you or what you already have in your fridge. The goal is to create a delightful, baked topping that complements the rich filling.

Tips for the Perfect Upside Down Pizza Casserole

• Drain the Fat: When browning your ground beef and Italian sausage, it’s crucial to drain off any excess fat before adding the other ingredients. This prevents the casserole from becoming greasy.
• Don’t Overcrowd the Skillet: Cook your meats and vegetables in a large skillet to ensure even browning. If your skillet is too small, cook in batches.
• Pierce the Dough: Before baking, remember to pierce your pizza dough several times with a knife. This allows steam to escape, preventing the crust from puffing up too much and ensuring it cooks evenly.
• Season Generously: Don’t forget the Italian seasoning and Parmesan on top of the dough. It adds a wonderful aroma and enhances the overall pizza flavor.
• Rest Before Serving: Allow the casserole to stand for 5-10 minutes after baking. This helps the cheese settle and makes it easier to serve neatly.
• Make It Ahead: You can prepare the meat and vegetable filling a day in advance. Store it in an airtight container in the refrigerator. When ready to bake, spoon it into your dish, top with dough, and proceed with baking.

What to Serve with Your Upside Down Pizza Casserole

This casserole is a meal in itself, but a simple side dish can perfectly complement its rich flavors:

• A crisp, simple side salad with Homemade Buttermilk Ranch Dressing is a classic pairing.
• Steamed or roasted vegetables, like broccoli or asparagus, provide a light contrast.
• Skillet Garlic Green Beans offer a flavorful and quick green side.
• For an extra Italian touch, serve with a side of garlic bread or breadsticks for dipping into any extra sauce.

Make-Ahead & Freezer Friendly

This Upside Down Pizza Casserole is an excellent candidate for meal prep. You can easily make it ahead and freeze it for those really busy days when cooking from scratch just isn’t an option:

• To Freeze: Assemble the casserole as directed, but do not bake it. Once assembled in a freezer-safe baking dish, wrap it tightly with plastic wrap and then with aluminum foil. Label with the date. It can be stored in the freezer for up to 3 months.
• To Bake from Frozen: Thaw the casserole completely in the refrigerator overnight. Once thawed, remove the plastic wrap and foil, and bake according to the recipe instructions. You may need to add an extra 5-10 minutes to the baking time to ensure it’s heated through and the crust is golden.
• Leftovers: Any leftover casserole can be stored in an airtight container in the refrigerator for 3-4 days. Reheat in the microwave or oven until warmed through.
