Step 1

Preheat oven to 375°F. Loosely place a large piece of aluminum foil into an 11x17-inch baking dish. (You could also use a large baking sheet.)

Step 2

Slice the top of the bread loaf into 1-inch (or ½-inch) sections, not slicing all the way through the loaf. The number of slices will depend on the length of your loaf.

Step 3

In a medium bowl, whisk together the olive oil, melted butter, Worcestershire sauce, garlic, salt, and parsley.

Step 4

Using a spoon, drizzle the mixture into the grooves of the bread.

Step 5

Stuff the mozzarella slices, cheddar cheese, and parmesan cheese into the grooves of the bread.

Step 6

Place the loaf on the aluminum foil and loosely wrap the foil around the bread, sealing the loaf inside.

Step 7

Bake for 20 minutes.

Step 8

After 20 minutes, carefully open up the foil and bake the bread for another 5-10 minutes, or until golden brown and the cheese is fully melted. Serve warm.
