While grilled cheese is a simple and classic comfort meal, legendary chef Gordon Ramsay turns it into something truly gourmet by adding the richer flavor of caramelized onions.

According to Ramsay, it's the rich, umami, slightly sweet and pungent spread of caramelized onions that give a grilled cheese its elevated flavor.

Start by assembling your bread, spreading the butter and layering the cheese, and then add the caramelized onions. Grill it as you normally would until perfectly crispy and melty.
