How to Make Supreme Pizza Casserole Recipe
Step 1: Prep Your Oven and Baking Dish
First things first, preheat your oven to 350 degrees Fahrenheit so it’s ready once the casserole is assembled. Give a 9×13-inch baking dish a light spray with non-stick cooking spray to ensure your masterpiece doesn’t stick and can be served cleanly.
Step 2: Cook the Penne Pasta
Boil your penne pasta according to the package’s instructions, aiming for al dente to keep it firm enough to hold up during baking. Once cooked, drain the pasta thoroughly and set it aside; this is going to be the sturdy canvas for the sauce and toppings that follow.
Step 3: Sauté the Ground Beef and Aromatics
In a large pot or skillet, cook and crumble the ground beef over medium heat until it’s browned and no longer pink. Drain any excess grease to keep the casserole from becoming too oily. Add dried minced onion (or fresh if using), minced garlic, Italian seasoning, and your pizza sauce to the beef. Stir everything together until well combined, then remove from the heat. This luscious sauce mixture is the savory heart of your casserole.
Step 4: Combine Pasta with Sauce and Assemble
Mix the cooked and drained penne pasta into the beef and pizza sauce mixture until every piece is coated in that mouthwatering red goodness. Pour this mixture into your prepped baking dish, spreading it out evenly for consistent baking. Next, sprinkle the shredded Mozzarella cheese over the top—this will melt and create that amazing cheesy crust. Arrange the pepperoni slices, green bell pepper slices, and black olives evenly over the cheese to finish it off like a supreme pizza.
Step 5: Bake and Serve
Cover the casserole dish with foil and place it in the preheated oven. Bake for about 25 minutes or until the casserole is hot and bubbly around the edges. Once out of the oven, carefully remove the foil and let the casserole stand for 5 minutes—this helps everything set and makes serving a breeze. Get ready for a hearty dish that tastes just like a supreme pizza, but with the comforting warmth of pasta baked to perfection!
How to Serve Supreme Pizza Casserole Recipe

Garnishes
Add fresh bursts of flavor and color by garnishing with chopped fresh basil or a sprinkle of crushed red pepper flakes if you like a little heat. A sprinkle of freshly grated Parmesan cheese can also elevate the cheesy experience even more.
Side Dishes
Pair this casserole with a crisp green salad tossed in a tangy vinaigrette to cut through the richness. Garlic breadsticks or a simple garlic butter toast make perfect companions, soaking up any extra sauce left on your plate.
Creative Ways to Present
For a crowd, bake the casserole in a pretty ceramic dish and bring it straight to the table to serve family-style. Or for a fun twist, prepare individual portions in small ramekins for a personalized supreme pizza experience that’s sure to impress.
Make Ahead and Storage
Storing Leftovers
Wrap your leftover Supreme Pizza Casserole tightly with plastic wrap or transfer it to an airtight container. It keeps well in the refrigerator for 3 to 4 days, making it a great option for easy weeknight dinners.
Freezing
This casserole freezes beautifully. Just make sure it’s completely cooled, then cover it securely with foil or plastic wrap and store in the freezer for up to 2 months. When ready, thaw overnight in the refrigerator for best results before reheating.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit for around 15 to 20 minutes until warmed through and bubbly again. Alternatively, microwave individual servings on high for 2 to 3 minutes, stirring halfway through to ensure even warming.
FAQs
Can I use a different type of pasta?
Absolutely! While penne is ideal for holding sauce and toppings, rigatoni, ziti, or even elbow macaroni would work wonderfully in this Supreme Pizza Casserole Recipe.
What if I want to make this vegetarian?
Simply skip the ground beef and use extra vegetables like mushrooms, zucchini, and eggplant, or add plant-based meat substitutes to keep that hearty, satisfying texture.
Can I make this recipe spicy?

How can I make this casserole less heavy?
Try swapping lean ground turkey or chicken for the beef, reduce the amount of cheese slightly, and load up on fresh veggies to lighten the dish without losing flavor.
