Slow cooker French onion soup

Prep time: 30 minutes
Total time: 7 hours 30 minutes
Serves: 4

Ingredients:

  • 1.75 kg cooking onions, thinly sliced (about 14 cups)
  • 3 tbsp butter, cubed
  • 1/4 tsp salt
  • 4 1/2 tsp all-purpose flour
  • 3 tbsp vermouth or dry white wine
  • 900 mL beef broth
  • 1/3 cup water
  • 1 demi-baguette
  • 1 tbsp butter, at room temperature
  • 2 cups grated gruyère or emmental cheese

Method:

Combine onions with butter and salt in slow cooker insert. Season with fresh pepper. Cover and cook on high until onions are soft and dark brown, about 6 hours.

Stir in flour until well combined. Stir in vermouth. Scrape up brown bits from bottom. Add broth and water. Cover and continue cooking on high for 1 1/2 hours.

Position rack in top third of oven. Preheat broiler. Cut bread into 8 slices, each 1/2 in. thick. Butter both sides and place on a baking sheet. Broil until lightly golden, about 1 minute per side.

Arrange 4 oven-safe soup bowls on a baking sheet. Ladle soup into bowls. Top each with 2 toasts. Sprinkle with cheese. Broil until cheese is bubbly, 2 to 4 minutes.

Make-ahead tip: Soup (without toasts) keeps well up to 3 days in the fridge or up to 2 months in the freezer. Flavour will improve as it sits.

For a stovetop version: Caramelize the onions and salt over medium until dark golden. Add flour, then vermouth, broth and water, and simmer, covered, for at least 30 minutes.
