This crockpot French onion soup is rich, flavorful, and topped with crusty bread and melty cheese—just like the classic, but made easier in the slow cooker. Let the onions caramelize low and slow, and enjoy this comforting, restaurant-style soup at home with minimal effort.

Ingredients

Scale

  • 4 large yellow onions, thinly sliced

  • 3 tbsp butter

  • 1 tbsp olive oil

  • 1 tsp sugar

  • 1 tsp salt

  • 1/2 tsp black pepper

  • 2 cloves garlic, minced

  • 1 tbsp Worcestershire sauce

  • 1/2 cup dry white wine (optional, or sub beef broth)

  • 6 cups beef broth (low sodium recommended)

  • 1 tsp fresh thyme leaves (or 1/2 tsp dried)

  • 1 bay leaf

For topping:

  • 1 baguette, sliced

  • 1 1/2 cups shredded Gruyère or Swiss cheese

Instructions

  1. Add sliced onions, butter, olive oil, sugar, salt, and pepper to the slow cooker. Stir to coat.

  2. Cover and cook on low for 8–10 hours or high for 4–5 hours, until onions are deep golden and caramelized.

  3. Add garlic, Worcestershire sauce, wine (if using), beef broth, thyme, and bay leaf. Stir to combine.

  4. Cover and cook on low for another 2–3 hours. Remove bay leaf before serving.

  5. To serve, preheat broiler. Place baguette slices on a baking sheet and toast for 1–2 minutes per side until crisp.

  6. Ladle soup into oven-safe bowls. Top each with a slice or two of toasted bread and a generous handful of cheese.

  7. Place bowls under the broiler until cheese is melted and bubbly, about 2–3 minutes.

  8. Serve hot and enjoy!

Notes

  • Make it vegetarian by swapping in veggie broth and skipping Worcestershire.

  • Gruyère is traditional, but Swiss, provolone, or mozzarella work too.

  • Prep everything the night before for an easy morning start.
