When you think about fondue, you may be reminded of the 1970s—the cheesy concoction was the life of the party throughout the decade. We’ve updated this vintage treat and made it more of a party pleaser with a creamy French onion soup twist. Grab a fondue fork (or just a spoon!) and share this interactive treat with friends and family. They’ll be clamoring to dunk bread, veggies, and more into this savory recipe.

While fondue might’ve had its heyday in America during the 1970s cocktail parties, this dish has a long history. French onion soup has an equally illustrious past—it was created in the court of King Louis XV. Who would’ve guessed that these two globetrotters would be joined by the common bond of cheese?

This fondue and a classic French onion soup topping also have something in common: Gruyére cheese. This melty variety works well in this recipe, which is probably why your fondue is going to disappear quickly. With all the fun that comes along with this dish, perhaps it should be called “fundue!”


  • 2 tablespoons oil
  • 2 large onions (diced)
  • 1/2 pound Swiss cheese (grated)
  • 1/2 pound Gruyére cheese (grated)
  • 2 tablespoon flour
  • 3/4 cup beef broth
  • 1/4 cup cooking sherry
  • 1/2 tablespoon concentrated beef broth
  • Pinch of nutmeg
  • Optional: 2 loaves French bread (cut into 1'' cubes and toasted, for serving)
  • Optional: Cooked asparagus spears (for serving)
  • Optional: Cooked potatoes (cubed, for serving)
  • Optional: Cooked broccoli (roughly diced, for serving)
  • Optional: Cooked cauliflower (roughly diced, for serving)

Steps to Make It

  1. Pour the oil into a medium-size sauté pan set to medium heat.

  2. Sauté the onions, tossing frequently, until brown and caramelized about 15 to 20 minutes.

  3. Set aside.

  4. Toss the cheeses with the flour in a medium mixing bowl until evenly coated.

  5. Set aside.

  6. Combine the beef broth, cooking sherry, and concentrated beef broth in a medium saucepot over medium-low heat and bring to a slight simmer. 

  7. Whisk the cheese into the mixture in four batches, waiting between each addition for the cheese to melt. Don't let the mixture come to a boil.

  8. When the final batch has melted completely, remove the pot from the heat and stir in the caramelized onions.

  9. Transfer the mixture to a fondue pot and sprinkle the nutmeg on top.

  10. Serve with the French bread, asparagus spears, potatoes, broccoli, or cauliflower, if desired.

Recipe Tip

  • Don’t have cooking sherry on hand? Suitable substitutes include dry red or white wine or apple cider vinegar.
