  • 4 Onions Sliced
  • ½ Cup Unsalted Butter

  • 1 Cup Dry Wed Wine
  • 3 Tbsp Flour

  • Slice onions thinly. Put onions into a large dutch oven or pot, add butter and bring to a medium-high heat on the stovetop. Add a pinch of salt and pepper, garlic, thyme and bay leaves. Cook for 25 minutes or until onions have caramelized and turned brown. Stir frequently.
