Description
A rich and savory Crockpot French Onion Soup recipe featuring tender caramelized onions, beef broth, and toasted cheesy bread. Easy to make in your slow cooker.
Ingredients
- 2 large sweet onions, halved and thinly sliced
- 2 cans (10-1/2 ounces each) condensed beef broth, undiluted
- 3/4 cup shredded Gruyere or Swiss cheese
- 1 large red onion, halved and thinly sliced
- 3/4 cup additional beef broth or white grape juice
- 2 teaspoons Worcestershire sauce
- 3 cups water
- 1 bay leaf
- 2 tablespoons butter, cubed
- 16 slices French bread (1/4 inch thick)
- 2 fresh thyme sprigs
- 1/2 teaspoon coarsely ground pepper
- 1 fresh parsley sprig, optional
Instructions
- Place the cubed butter in a 5-quart slow cooker. Add the sliced sweet and red onions, then sprinkle with coarsely ground pepper. Cover and cook on low heat for 5 to 6 hours until the onions are tender and soft.
- Stir in the condensed beef broth, water, additional broth (or juice), thyme, parsley (if using), bay leaf, and Worcestershire sauce. Cover and continue cooking on low for 2 to 3 hours until flavors are blended. Remove the herb sprigs and bay leaf.
- Preheat your oven broiler. Arrange the French bread slices on a baking sheet and broil 4 inches from the heat for 1-2 minutes per side until lightly toasted.
- Top the toasted bread slices with the shredded cheese. Broil for another 1-2 minutes until the cheese is melted and bubbly. Ladle the soup into bowls, top with the cheesy bread, and serve immediately.
Notes
For the liquid component traditionally provided by wine, I use extra beef broth or white grape juice to keep this recipe alcohol-free. You can also add a splash of apple cider vinegar for acidity.
