Recipe type: Soup
Serves: 4
Ingredients
  • 3 tablespoons butter
  • 4 large yellow onions, sliced thin
  • 1 tablespoon white sugar
  • 2 cloves garlic, minced
  • ½ cup red wine
  • 8 cups beef broth
  • 1 teaspoon salt
  • ¼ teaspoon dried thyme
  • 1 bay leaf
  • 8-10 slices of French bread, cut into 1 inch thick slices
  • ¾ cup shredded Gruyere cheese
Instructions
  1. Over medium-high heat, melt butter in a large pot. Add onions. Stir onions until they become translucent, about 10 minutes. Sprinkle onions with salt and sugar; reduce heat to medium. Continue to stir onions for 30-40 minutes, until they begin to carmelize. You may want to add a small amount of water or oil if they are sticking to the pan too much.
  2. Stir in garlic and cook until fragrant, about 1 minute.
  3. Stir in the red wine and scrape the small bits of browned food from the pot. Transfer onions into a slow cooker and pour in beef broth. Stir in thyme and bay leaf.
  4. Cook on High for 4 to 6 hours (or Low for 8-10 hours).
  5. About 10 minutes before serving, preheat the oven's broiler. Arrange bread slices on a baking sheet. Broil bread slices until toasted, 30 seconds to 1 minute per side. Watch them closely or they will burn!
  6. Fill oven-safe bowls ¾ full of onion soup and float a bread slice in each bowl. Top with cheese.
  7. Place filled bowls onto a baking sheet and broil until cheese is lightly browned and bubbling, about 1-2 minutes.
  8. Enjoy!
