Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish with cooking spray or olive oil.
Step 2: Cook the Ground Beef
Heat a large skillet over medium heat. Add the ground beef and cook for 6–8 minutes, breaking it apart with a wooden spoon until completely browned.

Drain excess grease if necessary.
Step 3: Add the Seasonings
Add the diced onion and cook for 2–3 minutes until softened. Stir in the minced garlic, Italian seasoning, oregano, paprika, black pepper, and salt.

Cook for another 30–60 seconds until fragrant.
Step 4: Add the Pizza Sauce
Stir the pizza sauce into the cooked beef mixture. Simmer for 2–3 minutes so the flavors combine.
Step 5: Assemble the Bake
Spread the seasoned beef mixture evenly into the prepared baking dish.

Arrange the mushrooms, green bell pepper, black olives, and pepperoni over the meat layer.
Step 6: Add the Cheese
Sprinkle the mozzarella and cheddar cheese evenly over the toppings. Finish with grated Parmesan cheese and red pepper flakes, if desired.
Step 7: Bake
Bake uncovered for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.

For a more golden cheese topping, broil for 1–2 minutes, watching carefully.
Step 8: Rest and Serve
Allow the casserole to rest for 5–10 minutes before slicing. Garnish with fresh basil or parsley and serve warm.
Helpful Tips for the Best Crustless Pizza Bake
– Drain the beef: Removing excess grease helps prevent a watery casserole.
– Use thick pizza sauce: A thicker sauce gives the bake a richer texture.
– Customize the toppings: Add cooked sausage, diced chicken, spinach, jalapeños, or extra vegetables.
– Avoid excess moisture: Cook mushrooms before adding them if they release a lot of liquid.
– Choose freshly shredded cheese: It often melts more smoothly than pre-shredded cheese.
– Make it spicy: Add crushed red pepper flakes or sliced jalapeños.
– Let it rest: Resting helps the casserole hold together when serving.
