My husband and I love French onion soup, so I wondered if I could turn it into a less labor-intensive dish by altering my recipe to work in a slow cooker. The rich, cheesy result was an instant winner at home. —Ronda Eagle, Goose Creek, South Carolina

- 2 tablespoons butter, cubed
- 2 large sweet onions, halved and thinly sliced
- 1 large red onion, halved and thinly sliced
- 1/2 teaspoon coarsely ground pepper
- 2 cans (10-1/2 ounces each) condensed beef broth, undiluted
- 3 cups water
- 3/4 cup white wine or regular-strength beef broth
- 2 fresh thyme sprigs
- 1 fresh parsley sprig, optional
- 1 bay leaf
- 2 teaspoons Worcestershire sauce
- 16 slices French bread (1/4 inch thick)
- 3/4 cup shredded Gruyere or Swiss cheese
- Place butter in a 5-qt. slow cooker. Top with sweet and red onions; sprinkle with pepper. Cook, covered, on low until onions are tender, 5-6 hours.
- Stir in broth, water, wine, herbs and Worcestershire sauce. Cook, covered, on low until flavors are blended, 2-3 hours. Remove herb sprigs and bay leaf.
- To serve, preheat broiler. Place bread on a baking sheet; broil 4 in. from heat until lightly toasted, 1-2 minutes per side. Top bread with cheese; broil until cheese is melted, 1-2 minutes. Divide soup among eight bowls; top with cheese toasts and serve immediately. Yield: 8 servings (2 quarts).
