1-Preheat oven and prep the baking sheet: First, gather your ingredients and preheat the oven to 400 degrees Fahrenheit to set the stage. Spray an 11×15 inch rimmed baking sheet with nonstick cooking spray for easy release later. Unroll the refrigerated pizza crust and press it evenly across the pan, up to the edges and sides, about 1/4 inch thick, creating a sturdy base for your school pizza sausage cheese.

2-Bake the crust initially for a solid foundation: Next, bake the crust on its own for 6 minutes until it’s lightly golden, giving it a head start.

3-Add the gravy, cheese, and sausage layers: While that’s happening, prepare the white gravy mix according to the package instructions and spread it evenly over the baked crust, right to the edges for full coverage. Then, sprinkle 2 cups of shredded mozzarella cheese over the gravy, followed by 1 cup of cooked sausage crumbles for that signature school pizza sausage cheese flavor.

4-Finish baking and rest before serving: Pop it back in the oven and bake for another 10 to 12 minutes, watching until the crust is fully cooked and the edges turn golden brown. Once done, take the pan out and let the pizza rest for 5 minutes before slicing, which helps everything set nicely.
