How to Make Crustless Pizza Bake Recipe
Step 1: Prepare the base layer
Start by pouring half a cup of marinara sauce into the bottom of a 9×13-inch baking dish. This creates a flavorful sauce foundation that will keep every bite saucy and satisfying.
Step 2: Mix the toppings
In a large bowl, combine the ground Italian sausage, chopped green pepper, mushrooms, onions, and any other toppings you love. Add one cup of shredded mozzarella and one cup of marinara. Stir everything together until well incorporated—this mixture is the heart and soul of your crustless pizza bake.
Step 3: Assemble the bake
Pour the topping mixture on top of the sauce in the baking dish, spreading it out evenly. This layer is packed with savory ingredients and lots of cheesy goodness.
Step 4: Add the cheese topping
Sprinkle the remaining two cups of mozzarella cheese over the top of your assembled bake. This final layer will melt beautifully, creating a golden, bubbly cheese blanket.
Step 5: Bake it to perfection
Bake the casserole at 400°F (200°C) for 20 minutes. This allows the sausage to cook through and the cheese to bubble and brown nicely.
Step 6: Optional broil for extra crispiness
If you love your cheese with a little crispy, golden edge, broil the bake for an additional 3-5 minutes. Just keep an eye on it so nothing burns—this step adds a fantastic finishing touch.
Step 7: Enjoy the feast!
Your crustless pizza bake is ready to serve. Grab a spatula, dish it out, and enjoy every gooey, flavorful bite.
How to Serve Crustless Pizza Bake Recipe

Garnishes
Sprinkling freshly chopped basil or oregano on top right before serving adds a bright, herbal note that enhances the Italian flavors beautifully. A light drizzle of extra virgin olive oil or a pinch of crushed red pepper flakes can elevate the dish even more.
Side Dishes
This crustless pizza bake pairs wonderfully with a crisp green salad tossed in a tangy vinaigrette, which balances out the richness. Garlic bread or a simple roasted vegetable medley also complement the hearty main dish perfectly.
Creative Ways to Present
Serve generous scoops in shallow bowls or on plates with a sprinkle of Parmesan cheese for a restaurant-style feel. You can also serve it in smaller, individual ramekins for a fun dinner party presentation that lets everyone have their own cheesy pizza bake experience.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftovers tightly with plastic wrap or transfer to an airtight container. Stored in the refrigerator, your crustless pizza bake will stay fresh for up to 3-4 days—perfect for quick, satisfying meals later in the week.
Freezing
You can freeze the bake either before or after baking. If freezing uncooked, assemble it and cover tightly with foil and plastic wrap, then freeze for up to 3 months. Thaw overnight in the fridge before baking. For cooked leftovers, portion them out and freeze, then reheat directly from frozen or after thawing.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through to keep the cheese nice and melty. Alternatively, the microwave works well for a quick reheat—just watch the cheese so it doesn’t overcook.
