Step 1

Preheat oven to 400 degrees.

Step 2

Slice the bread vertically and horizontally being careful to not cut all the way through the bread, stop about 1/4 inch from the bottom of the loaf. Place on a sheet of aluminum foil.

Step 3

Melt butter in a skillet over medium heat. Add in chiles, onion and garlic. Cook just until garlic becomes fragrant and onions start to soften, about 1 minute. Remove from heat.

Step 4

Drizzle the hatch chile butter into each cut of the bread. Gently part the bread to allow the butter mixture to work its way into the tiny spaces. Gently push chiles into the cuts with your finger or a spoon.

Step 5

Combine cheddar, mozzarella and pepper jack cheese together in a bowl. Gently stuff the cheese into each cut of the bread.

Step 6

Wrap the bread in the aluminum foil and bake for 15 minutes. Uncover and bake for an additional 10 minutes or until the cheese is bubbly. Remove from the oven and serve immediately.
