French onion soup is a masterpiece—but it shouldn’t get all the glory. Caramelized onions, with their deep sweetness and golden edges, can transform far more than a bowl of broth and cheese.
These recipes take that rich, slow-cooked flavor and layer it into grilled cheese, casseroles, dips, and more.
If you’re anything like me, you’ll wonder why you didn’t start putting French onion magic into everything years ago.
1. French Onion Grilled Cheese
Golden bread crackles as you bite in, giving way to a gooey center loaded with caramelized onions and melted Gruyère. The mix of sweet, savory, and cheesy feels luxurious, yet rustic.
