Preheat the oven to 375°F. Line a baking sheet with foil or parchment.
Cut the French bread in half lengthwise and place on the baking sheet with the cut side up. Optional step: to prevent the sides of the bread from curling up too much while baking, take another baking sheet or a clean cutting board and press down on the bread.
1 loaf French bread or Italian bread
In a medium-sized bowl, mix the softened butter, garlic, parmesan, parsley, and salt. You can use a spoon or a hand mixer if it’s easier.
1/2 cup unsalted softened butter, 3-6 cloves garlic, (use less if you want it less garlicky) grated with a microplane, very finely chopped or pressed through a garlic press, 1/2 cup finely shredded Parmesan (shred yourself not pre-grated or shredded), 1-2 Tbsp. fresh parsley, chopped, pinch salt (or if using salted butter, omit additional salt)
Spread the butter mixture all over the sliced sides of the bread and bake for 8-10 minutes.
Remove the bread from the oven to add your pizza toppings. Spread some marinara first, then mozzarella cheese, pepperoni, and any other toppings you like on your pizza.
12-17 oz. pizza sauce (your favorite), 2 cups low-moisture shredded mozzarella cheese, 1/2 cup pepperoni
Bake again for ~10-12 minutes or until cheese is melty and delicious! Broil for 1-2 minutes if desired.
Garnish with fresh basil, grated Parmesan cheese, chili flakes, etc. and serve with more pizza sauce if desired. Slice and enjoy!
For serving: fresh basil, black pepper, chili flakes, parmesan cheese, ranch, etc.
