Ingredients
Scale
Soup
- 3 large white onions, sliced
- 3 tablespoons butter
- 64 ounces beef broth (reduced sodium preferred)
- 1 tablespoon Worcestershire sauce
- 1 clove garlic, minced
- ⅓ cup dry sherry
- 4 sprigs fresh thyme (or 1 teaspoon dried thyme)
- 1 bay leaf
Topping
- 8 slices French bread (stale or dry is best)
- ¾ cup shredded Gruyere cheese
- ½ cup shredded Emmental cheese
- 6 tablespoons shredded Parmesan cheese
Instructions
- Caramelize Onions: In a large non-stick pan, melt the butter over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally until they turn golden and caramelized, about 20 minutes. This slow cooking brings out the onions’ natural sweetness.
- Transfer to Slow Cooker: Once the onions are caramelized, transfer them to the slow cooker. Add the beef broth, Worcestershire sauce, minced garlic, dry sherry, fresh thyme sprigs, and bay leaf. Stir to combine all ingredients.
- Slow Cook the Soup: Set the slow cooker on low and cook the soup for 6 to 8 hours. This allows the flavors to meld beautifully and intensifies the rich beefy broth.
- Prepare for Serving: When cooking is complete, remove and discard the bay leaf. Ladle the hot soup into oven-safe bowls, then top each bowl with a slice of dry French bread. Sprinkle the shredded Gruyere, Emmental, and Parmesan cheeses generously over the bread.
- Broil the Toppings: Place the bowls under a broiler for 2 to 3 minutes until the cheese melts, bubbles, and turns a lovely golden brown. This creates a deliciously cheesy crust on top of the soup.
Notes
- This Crockpot French Onion Soup is favored for its rich beef broth and deeply caramelized onions that offer a perfect harmony of savory and sweet flavors.
- Using stale or dry French bread helps it hold up better under the cheese and soup without becoming soggy too quickly.
- Adjust cheese quantities to your taste preference—Gruyere contributes nuttiness, Emmental adds creaminess, and Parmesan offers a sharp, salty finish.
