How To Make French Onion Soup in the Slow Cooker

When I discovered that you can make caramelized onions in the slow cooker with no stirring and virtually no work, it was only a small step from there to French onion soup. Although I’ve made this bistro favorite the classic, Julia-inspired way, now that I know how to make it in the slow cooker, I’m probably never going back to stovetop!


3 pounds 
  • yellow onions, peeled, sliced, and cut into quarter-moons
  • 2 tablespoons 
  • unsalted butter, melted
  • 2 tablespoons 
  • olive oil
  • 2 teaspoons 
  • kosher salt, plus more as needed
  • Freshly ground black pepper
  • 10 cups 
  • reduced-sodium beef broth
  • 2 tablespoons 
  • balsamic vinegar
  • 3 tablespoons 
  • brandy (optional)

To Serve
  • 4 to 6 
  • toasted baguette slices per bowl
  • 1/3 cup 
  • grated Gruy√®re cheese per bowl (1 1/3 to 2 cups total)
  • Chopped shallot or fresh onion (optional)

  • Cutting board and chef's knife
  • 5-quart or larger slow cooker
  • Wooden spoon
  • Oven-safe soup bowls
  • Rimmed baking sheet


  1. Season the onions. Place the onions in a 5-quart or larger slow cooker. Stir in the butter, oil, salt, and a generous amount of pepper.
  2. Cook on LOW for 12 hours. Cover and cook on the LOW setting overnight until the onions should be dark golden-brown and soft, 12 hours or overnight.
