For the thyme-infused caramelized onions;
  • 4 sweet onions, sliced
  • 3 tablespoons butter
  • 10 sprigs thyme
  • butchers twine
  • ½ teaspoon salt
  • ¼ teaspoon pepper
For the homemade sloppy joes;
  • 2 pounds ground beef

  • 3 tablespoons apple cider vinegar
  • 2 teaspoons salt
  • 1 teaspoon pepper

  2. Make a thyme bundle by wrapping the thyme sprigs with butcher's twine or wrap them in cheesecloth.

  3. Add the thyme bundle to the onions. Cook, over medium heat, stirring occasionally until the onions are deeply caramelized and reduced. Remove the thyme and discard. Season with salt and pepper. Stir.

  4. Keep the onions warm until serving or cover and refrigerate for up to 4 days if making them in advance.
