Why You’ll Love This French Onion Gnocchi

This recipe takes everything you love about French onion soup and turns it into a satisfying, cheesy, skillet meal. The gnocchi gets pan-fried until golden and crispy on the outside, while the onions are slowly caramelized to perfection. Gruyère adds that signature French onion flavor, melting into every bite. Best of all, it’s made in one pan, meaning less cleanup and more flavor. It hits all the right notes: savory, cheesy, cozy, and incredibly simple to prepare.

Ingredients

  • 2 pounds of yellow onions, which equals roughly 2 large or 4 medium onions
  • 1 small bunch fresh thyme, divided
  • 2 tablespoons olive oil, divided
  • 2 (16- to 18-ounce) packages fresh, shelf-stable, or frozen potato gnocchi (do not thaw)
  • 2 tablespoons unsalted butter
  • 1 teaspoon kosher salt, plus more as needed
  • 1/2 teaspoon freshly ground black pepper, plus more for serving
  • 6 ounces Gruyère cheese, grated (about 1 1/2 cups)
  • 1/4 cup dry white wine
  • 1 teaspoon balsamic or sherry vinegar

Step-by-Step: How to Make French Onion Skillet Gnocchi

  1. Slice the onions thinly and strip the thyme leaves until you have about 2 tablespoons.
  2. Heat 1 tablespoon olive oil in a large broiler-safe skillet over medium heat. Add one package of gnocchi in a single layer and cook undisturbed for 3 to 5 minutes, until golden brown. Remove to a baking sheet. Repeat with the second tablespoon of olive oil and remaining gnocchi.
  3. Using the same skillet, add the butter and let it melt over medium heat. Add sliced onions, half the thyme, salt, and pepper. Cook, stirring often, until onions are deeply caramelized, soft, and reduced in volume. This takes about 28 to 30 minutes.
  4. While the onions cook, grate the Gruyère cheese and set your oven to broil with a rack positioned 6 to 8 inches from the top.
  5. Once onions are caramelized, pour in the white wine, scraping up any browned bits. Let the wine cook off, then stir in vinegar.
  6. Add the gnocchi back into the skillet, stirring well to combine. Season with more salt if needed and spread into an even layer.
  7. Sprinkle Gruyère cheese over the top and broil for 4 to 6 minutes until bubbly and golden.
  8. Garnish with remaining thyme and a few extra grinds of black pepper. Serve warm.

Helpful Tips

  • Use a cast iron or oven-safe skillet for the best caramelization and broiling.
  • Don’t rush the onions. Slow caramelization is key to the flavor.
  • Use pre-shredded cheese for a shortcut, but grating it fresh will melt more evenly.
  • If using frozen gnocchi, do not thaw before cooking.

Substitutions And Variations

  • Cheese: Swap Gruyère for Swiss or even mozzarella for a more budget-friendly option.
  • Wine: Use vegetable or chicken broth if you prefer to avoid alcohol.
  • Gnocchi: Cauliflower gnocchi works well for a lighter, gluten-free twist.
  • Add protein: Stir in cooked sausage, shredded rotisserie chicken, or even white beans.
  • Extra veggies: Add sliced mushrooms or spinach for extra nutrition and texture.

Storage Instructions

Keep leftovers in a sealed container in the fridge for up to four days. To reheat, place in a skillet over medium-low heat until warmed through, or microwave in 30-second bursts. If the cheese looks too dry, add a splash of broth or water to revive it.
