Prepare the Bread

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
2. Cut the Bread: Take the loaf of Italian bread and use a serrated knife to slice it into a grid pattern. Make horizontal cuts and then vertical cuts to form squares, being careful not to slice all the way through—leave the bottom intact so the bread holds together.
3. Stuff with Cheese: Gently pull apart the cuts in the bread and stuff the mozzarella and Parmesan cheese into the openings, making sure the cheese is evenly distributed.

Make the Garlic Butter

1. Prepare the Garlic Butter: In a small bowl, combine the melted butter, minced garlic, chopped parsley, salt, and pepper. Stir well to combine.
2. Brush the Bread: Use a pastry brush to generously coat the top and between the cuts of the bread with the garlic butter mixture. Make sure to get the butter in all the crevices for maximum flavor.

Bake the Bread

1. Wrap and Bake: Wrap the stuffed bread loosely in aluminum foil and bake in the preheated oven for 15 minutes.
2. Unwrap and Continue Baking: After 15 minutes, unwrap the bread and continue baking for an additional 10-15 minutes, or until the cheese is fully melted and the bread is golden brown and crispy.

Serve and Enjoy

1. Serve Warm: Once the bread is done, remove it from the oven and let it cool for a couple of minutes. Serve it warm for the best experience!
2. Pull Apart: Encourage everyone to tear off pieces of the cheesy bread and enjoy! The cheesy, garlicky goodness will be irresistible.
