Begin by softening 4 tablespoons of unsalted butter in a mixing bowl until creamy. Mince 2 to 3 garlic cloves and add them to the butter, along with a sprinkle of chopped parsley for freshness. Mix well until combined, creating a fragrant garlic butter spread.

Take slices of your chosen sturdy bread and generously spread the garlic butter mixture on one side of each slice. Position the unbuttered side facing up, then layer on a combination of shredded mozzarella, sharp cheddar, and provolone cheese to form a gooey filling.

Preheat a non-stick skillet over medium-low heat—wait for about 2 to 3 minutes until it's warm. Carefully place the assembled sandwiches, buttered-side down, in the skillet.

Cook the sandwiches for about 3 to 4 minutes, or until the bottom is golden brown and the cheese begins to melt.

After flipping, allow the second side to grill for another 3 to 4 minutes until it turns a beautiful golden brown as well.

Once both sides are perfectly golden and the cheese is wonderfully melted, remove the Garlic Bread Grilled Cheese from the skillet. Slice each sandwich in half for easy handling and serve them hot.
