Preheat oven to 350°F.

Mix butter with garlic and Worcestershire sauce, set aside.

Halve bread horizontally. Slice each half piece of bread crosswise into serving size pieces, cutting only three-fourths of the way to the bottom (do not cut bread into individual pieces).

Place each half piece of bread on a baking sheet, crust side down.

Spread all cut surfaces (including between the crosswise cuts you made) with the garlic-butter mixture.

Cut or tear the cheese into pieces that will fit to cover the entire surface of both halves of bread.

Bake until cheese melts and lightly browns, about 20 minutes.
