Simple Pizza Casserole Recipe Without Pasta Ingredients
For a standard 9×13-inch casserole, we use the following ingredients.
For the Pizza Meat Layer
- 1 pound ground beef
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 cups pizza sauce
For the Cheese and Topping Layers
- 2 cups shredded mozzarella cheese
- ½ cup shredded cheddar cheese
- ¼ cup grated Parmesan cheese
- 20 to 25 slices pepperoni

- ½ cup sliced mushrooms
- ¼ cup sliced black olives, optional
Optional Garnish

How to Make a Simple Pizza Casserole Without Pasta
Step 1: Prepare the Baking Dish
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil.
Greasing the dish helps prevent the cheese and sauce from sticking to the edges. It also makes serving and cleanup easier.
Step 2: Cook the Ground Beef
Place a large skillet over medium-high heat. Add the ground beef and diced onion. Cook for approximately 6 to 8 minutes, breaking the meat into small pieces with a wooden spoon.
Continue cooking until the beef is fully browned and the onion is soft. Drain any excess grease from the skillet so the finished casserole does not become oily.
Add the minced garlic, Italian seasoning, oregano, salt, and black pepper. Stir for about 30 seconds, allowing the garlic and dried herbs to become fragrant.
Step 3: Add the Pizza Sauce
Pour the pizza sauce into the skillet and stir until the beef is evenly coated. Reduce the heat to low and allow the mixture to simmer for 3 to 5 minutes.
The brief simmer helps the seasonings blend into the sauce and creates a richer pizza flavor. If the sauce seems too thick, we can add a few tablespoons of water. If it seems too thin, allow it to simmer uncovered for another minute or two.
Step 4: Build the Pizza Casserole
Spread the seasoned meat and pizza sauce mixture evenly across the prepared baking dish.
Sprinkle approximately 1½ cups of mozzarella cheese over the meat layer. Add the diced bell pepper, mushrooms, and black olives. Arrange the pepperoni slices over the vegetables.
Finish with the remaining mozzarella, cheddar cheese, and grated Parmesan.
The layers do not need to be exact. We can adjust the toppings according to personal preference, but placing some cheese on top ensures a golden, melted finish.
Step 5: Bake Until Hot and Bubbly
Cover the baking dish loosely with aluminum foil and bake for 15 minutes.
Remove the foil and continue baking for another 10 to 15 minutes, or until the cheese is fully melted, bubbling around the edges, and lightly golden.
For a more browned cheese topping, place the casserole under the broiler for 1 to 2 minutes. Watch it closely because the cheese can brown quickly.
Step 6: Rest Before Serving
Remove the casserole from the oven and allow it to rest for 5 to 10 minutes.
Resting gives the sauce time to settle and makes the casserole easier to scoop. Garnish with fresh basil, Parmesan cheese, or red pepper flakes before serving.
Recipe Tips for the Best Pizza Casserole
Drain the Meat Thoroughly
Ground beef can release a significant amount of fat while cooking. Draining it well keeps the pizza casserole rich without making the sauce greasy.
For a leaner option, we can use ground turkey, ground chicken, or lean ground beef.
Use Thick Pizza Sauce
Pizza sauce is usually thicker and more heavily seasoned than regular pasta sauce. Its concentrated flavor helps the casserole taste more like a traditional pizza.
If only marinara sauce is available, we can add a small amount of Italian seasoning, garlic powder, and dried oregano.
Shred Cheese From a Block
Freshly shredded mozzarella melts smoothly and creates a better cheese pull. Pre-shredded cheese is convenient, but it often contains ingredients that reduce clumping and may affect how evenly it melts.
Avoid Overloading the Casserole
Too many vegetables can release excess moisture. If using watery vegetables such as zucchini, fresh tomatoes, or spinach, cook them briefly and drain any liquid before adding them.
Let the Casserole Rest
Serving immediately may cause the sauce and cheese to spread across the plate. A short resting period creates cleaner portions and a more cohesive texture.

How to Store and Reheat Pizza Casserole
Allow the casserole to cool before transferring leftovers to an airtight container.
Store in the refrigerator for up to 4 days.
To reheat an individual portion, place it in a microwave-safe dish and heat for 1 to 2 minutes. Continue heating in short intervals until hot throughout.
For larger portions, cover the baking dish with foil and warm it in a 350°F (175°C) oven for approximately 15 to 20 minutes.
Adding a small amount of extra mozzarella before reheating gives leftovers a freshly baked appearance.

When ready to bake, thaw the casserole overnight in the refrigerator. Bake at 375°F (190°C) until hot and bubbly.
We can also freeze fully baked leftovers in individual portions. This makes the recipe convenient for quick lunches or easy dinners.
