Slow Cooker:

  • 2 pounds onions sliced
  • 3 tablespoons melted butter
  • 1 teaspoon each salt and black pepper


  • 1/2 cup all-purpose flour
  • 6 cups beef stock
  • 1/4 cup dry white wine
  • 2 tablespoons cognac
  • 1/2 teaspoon rubbed sage
  • 1/4 teaspoon ground bay
  • 4-6 1- inch slices French bread
  • 1/2 cup shredded Murray's Fondue mix cheese gruyere, raclette and fontina combined


  • Stir butter, onions, salt and pepper in the crock.
  • Cover and cook on low for 8-10 hours until caramelized.
  • At this point you can chill the onions for a few days until needed, or continue.
  • Place onions in a large saucepan and stir in the flour.
  • Add the wine, beef stock, cognac, ground bay and rubbed sage.
  • Bring mixture to a boil, stirring, and stir for about one minute until it thickens slightly.
  • Place soup in a stoneware crock and top with bread and cheese; broil until cheese melts and browns slightly. Or separately toast the bread with cheese and dunk in soup if you don't have heatproof bowls.
