French Onion Grilled Cheese

French Onion Grilled Cheese
One of our favorite comfort foods—French onion soup—meets crowd-pleasing grilled cheese in a sandwich that’s got the flavors of both dishes, minus a lot of the traditional sodium and sat fat. Silky caramelized onions are the star here: their pungent, concentrated flavor means that just a touch of Gruyere is more than enough to make this sandwich sing. The other key? Shaving the cheese with a Microplane, which allows the cheese to distribute its melty goodness evenly, and makes just a bit of cheese feel like a lot.
