How to Make Crustless Pizza Bake

Step 1: Preheat the Oven

Preheat the oven to 375°F or 190°C.

Lightly grease a 9 x 13-inch baking dish with cooking spray or a small amount of olive oil.

Step 2: Brown the Ground Beef

Heat olive oil in a large skillet over medium-high heat.

Add the ground beef and cook for 6 to 8 minutes, breaking it into small pieces with a wooden spoon.

Once browned, drain excess grease if necessary.

A well-browned meat layer gives Crustless Pizza Bake a richer, more savory flavor.

Step 3: Add Onion and Garlic

Add the diced onion to the skillet and cook for 3 to 4 minutes until softened.

Stir in the garlic, Italian seasoning, smoked paprika, salt, and black pepper.

Cook for about 30 seconds, just until fragrant.

Step 4: Build the Base Layer

Spread the seasoned beef mixture evenly across the bottom of the prepared baking dish.

Press it down lightly with the back of a spoon so the base is even.

This helps Crustless Pizza Bake hold together more neatly when sliced.

Step 5: Add the Pizza Sauce

Spoon the pizza sauce over the meat and spread it into an even layer.

Use enough sauce to cover the surface, but avoid adding too much because excess liquid can make the casserole watery.

Step 6: Add the Toppings

Scatter mushrooms, bell pepper, black olives, and pepperoni evenly over the sauce.

You can adjust the toppings to match your favorite pizza combination.

This casserole works especially well with toppings that are not too watery.

Step 7: Add the Cheese

Sprinkle mozzarella evenly across the top, then add Parmesan.

Finish with oregano and red pepper flakes if using.

The cheese layer should cover most of the toppings so Crustless Pizza Bake develops a bubbly, golden top.

Step 8: Bake

Place the dish in the oven and bake uncovered for 20 to 25 minutes.

The cheese should be completely melted and bubbling around the edges.

For extra browning, broil for 1 to 2 minutes at the end, watching carefully so the cheese does not burn.

Step 9: Rest Before Slicing

Remove the casserole from the oven and let it rest for 8 to 10 minutes.

This resting time allows the layers to settle and makes Crustless Pizza Bake easier to portion.

Step 10: Garnish and Serve

Top with fresh basil, parsley, extra Parmesan, or a sprinkle of red pepper flakes.

Serve Crustless Pizza Bake warm with your favorite side dishes.

Serving Suggestions

Crustless Pizza Bake pairs well with a crisp green salad, Caesar salad, cucumber salad, or roasted vegetables.

Recipe Tips

Use lean ground beef to prevent the casserole from becoming greasy.

Drain the meat well after browning.

Avoid very watery vegetables unless you cook or drain them first.

Use a thick pizza sauce or marinara rather than a very thin tomato sauce.

Shred mozzarella from a block if possible for the best melting texture.

The casserole slices more cleanly after resting for several minutes.

Do not overload the casserole with toppings. Too many toppings can release excess moisture.

Broil briefly at the end if you want browned cheese.

Easy Variations

For a sausage version, replace half or all of the ground beef with cooked Italian sausage.

Crustless Pizza Bake can also be made with ground turkey or chicken for a lighter option.

For a vegetable-heavy version, add sautéed zucchini, spinach, mushrooms, roasted peppers, or artichoke hearts.

For a Hawaiian-style variation, use cooked ham and a small amount of well-drained pineapple.

If you prefer a spicy version, add jalapeños, hot Italian sausage, crushed red pepper, or spicy pepperoni.

For extra cheese flavor, mix mozzarella with provolone or cheddar.

Make-Ahead Instructions

Crustless Pizza Bake is a convenient make-ahead dinner.

Prepare the meat base, spread it in the baking dish, add sauce and toppings, then cover and refrigerate for up to 24 hours.

When ready to cook, add the cheese if you stored it separately and bake as directed. You may need an extra 5 to 10 minutes if the casserole goes into the oven cold.

Storage and Reheating

Store leftover Crustless Pizza Bake in an airtight container in the refrigerator for up to 4 days.

To reheat, place individual portions in the microwave and heat in short intervals until hot.

For a firmer texture, reheat in a 350°F or 175°C oven for 10 to 15 minutes.
