If you'remaking your pizza doughfrom scratch, mix the dry ingredients with warm water, then knead the dough for 5-10 minutes. Let it rest while covered, then roll out the dough on a floured surface. For a pre-made pizza crust, simply remove it from the packaging.
Set your oven to 400°F (204°C) for a homemade pizza dough or follow the recommended temperature on the pre-made pizza crust's package.
Place the rolled-out pizza dough or pre-made crust on a baking sheet or pizza stone. Optionally, you can brush the dough with olive oil to enhance the flavor. Spoon a thin layer of cheese sauce onto the dough, and then put it in the preheated oven for 15 minutes or until almost fully cooked. This step helps ensure a crispy crust.
While the pizza crust is baking, cook the elbow macaroni according to the package instructions or create your homemade version of mac and cheese.
Remove the par-baked pizza crust from the oven and evenly spread the cooked macaroni on top. Sprinkle a cup of shredded cheddar cheese and a cup of mozzarella cheese over the macaroni. Add chopped green onions for an extra touch of flavor, though this is optional.
Place the assembled pizza back into the oven and bake for an additional 12-15 minutes, or until the crust is golden brown and the cheese has melted.
