Preheat your oven to 375 degrees.
Place your loaf of bread on a cutting board, and using a serrated knife, make 1-inch diagonal cuts most of the way through the bread. Make sure to leave the bottom of the crust intact. Repeat with another set of diagonal cuts in the opposite direction, creating a crosshatch pattern.
Pour the melted butter into the cuts in the bread. Next, use a spoon to drip the pesto into the cuts. Finally, stuff the shredded cheese into the cuts.
Wrap the bread in aluminum foil and place it on a baking sheet then place the baking sheet into the oven and bake for 15 mins. After 15 minutes have passed, open the foil to expose the top of the bread loaf and bake it for an additional 10 mins. Then remove the bread from the oven, let it cool for a minute, and enjoy while warm!
