Start with thinly sliced onions, cooked slowly to coax out their sugar so that they reach a deeper level of sweetness while still retaining their savory, oniony character. Add a splash of sherry and a tiny dollop of beef bouillon paste, plus a smattering of Gruyère cheese, and you get the recognizable (and beloved) flavors of French onion soup.

French onion soup is about as comforting and comforting as food gets. We'll never tire of this combination of flavors, and have long been willing to pair them with baked cheese, a bowl of pasta, a hearty sandwich, and more. Try it yourself with these easy French onion–ified foods, perfect for a bistro meal at home, or any night that needs melty cheese.

Pack your baked potato with Frenched onions, Gruyère cheese, and a sprinkle of fresh thyme. Then pop the potatoes under the broiler to get the cheese nice and melty. Before serving, add a dollop of sour cream — or crème fraîche, if you’re feeling fancy.

The jammy, sweet caramelized onions in this recipe — combined with an umami-packed mixture of broth, Worcestershire sauce, fish sauce, Parmesan and cheese — make this French onion pasta unforgettable. The sauce, based on classic French onion soup, has body and richness, while still being light enough to delicately coat the al dente bucatini.

In their book Wine Food, sommelier Dana Frank and recipe developer Andrea Slonecker pair funky, bright wines with flavorful, vegetable-forward dishes, including this French onion soup recipe. In this vegetarian version of classic French onion soup, blue cheese and Oloroso sherry bring new layers of flavor and depth that you'll want to make again and again. Notes of toasted nuts and fruit compote in the sherry pair well with caramelized onions, and its briny acidity cuts through the richness of the cheese.

The process of slowly sautéeing onions until their sugars release and brown is a fundamental cooking technique, and it works best with onions that have a high sugar content, like yellow onions. This recipe, with its savory beef notes from bouillon and nutty sweetness from dry sherry, can be used as the basis for a classic French onion soup as well as the other dishes on this list.

French Onion-Style White Bean Soup

This soup goes back, as Gwyneth Paltrow writes in My Father's Daughter, to a French restaurant called La Serre in Los Angeles where she used to eat with her father. "I've always loved the idea of French onion soup," Gwyneth says, "without actually liking the soup itself." She cooks the onions slowly with fennel and lots of garlic, makes the soup with vegetable stock and the nontraditional addition white beans, then sets the filled bowls under the broiler topped with a slice of toasted bread and a generous handful of grated cheese. Best part? This soup can be made ahead and enjoyed in the fridge for up to three days.

At Tzuco, in Chicago, the French onion soup arrives to the table piping hot, topped with a bubbling layer of Gruyère cheese. Hiding under the blanket of cheese, a thick slice of baguette soaks up a soup suffused with flavor from a mountain of jammy onions, balsamic vinegar, and bay leaves. French onion soups can lean quite beefy, but chef Carlos Gaytán uses a gentle base of chicken broth that allows the allium flavors to truly shine. Poblano chiles add a mild, vegetal heat and slight charred flavor. To ensure even caramelization, keep the onions in an even layer while they cook.

Former F&W food editor Grace Parisi reinvented the classic grilled cheese sandwich with this version, which emulates the gooey, cheese-y top of a bowl of French onion soup. Give yourself time to cook the onions slowly; caramelized onions take almost an hour to achieve their sweet flavor and melty texture, but are worth the wait.

A mix of five different alliums—shallots, scallions, and sweet, yellow, and red onions—upgrades this classic caramelized onion dip with layers of flavor. Yellow and red onions give it bite, while Vidalia onion and shallots lend a pleasant sweetness. Taking the time to cook the onions low and slow concentrates their flavor, while adding scallions halfway through cooking keeps them just fresh enough to serve with chips, toasted bread, or vegetables.

Hugue Dufour makes a pork broth for his French onion soup using bacon for smokiness and a pig's foot for richness (yum!). You can omit the pig's foot for a lighter broth; either option yields a rich and delicious soup.

This whole roasted onion hints at the pleasures of French onion soup with its stuffing of beefy caramelized onions. The white onion itself, already mild, mellows further while roasting and offsets the sweet intensity of the Frenched onions.
