Start by placing your pizza stone (if using) in the oven and preheating to 450°F. If you don’t have a stone, a regular baking sheet works fine – just don’t preheat it. Give your oven a good 20-30 minutes to fully heat up.
While the oven heats, let your pizza dough come to room temperature on your counter for about 30 minutes.
Mix the melted butter with minced garlic and Italian seasoning in a small bowl. This will be our flavor-packed crust coating.
On a lightly floured surface, stretch your dough into a 14-16 inch circle. Don’t use a rolling pin – gentle stretching with your hands keeps those nice air bubbles in the dough.
Transfer the dough to a pizza peel or the back of a baking sheet lined with parchment paper.
Brush the entire surface of the dough with your garlic butter mixture, getting right to the edges. This creates a protective barrier that helps prevent the crust from getting soggy.
Warm up your mac & cheese slightly in the microwave (about 30 seconds) – this helps it spread more easily. Drop spoonfuls all over the pizza and gently spread them out, leaving a 1/2 inch border for the crust.
Layer on about half the mozzarella and cheddar, then sprinkle on your crumbled bacon. Add the remaining cheese on top.
Finish with a dusting of Parmesan cheese around the edges of the crust.
Slide the pizza onto your preheated stone or baking sheet. Bake for 12-15 minutes, rotating halfway through, until the cheese is bubbly and spotted, and the crust is deep golden brown underneath.
Let the pizza rest for about 3 minutes after coming out of the oven – this helps the cheese set up so your toppings don’t slide off when you cut it. Sprinkle with fresh parsley if using, then slice and serve.
