  • Hamburger buns
  • Butter
  • Olive oil
  • Salt and pepper


  1. Caramelize the Onions:

  3. Assemble the Burgers:

Serving and Storage Tips for French Onion Soup Burgers:

  1. Serve Immediately for Best Flavor:
    • French Onion Soup Burgers are best enjoyed immediately after assembling to ensure the beef patties are juicy and the cheese is melted. Serve them hot off the grill or skillet for optimal flavor.

  5. Refrigerate Leftovers Promptly:
    • If you have leftover French Onion Soup Burgers, refrigerate them promptly in an airtight container once they have cooled down. Proper storage helps maintain their freshness and prevents bacterial growth.
  6. Reheat with Caution:
    • When reheating leftover French Onion Soup Burgers, do so gently to prevent the beef patties from drying out. Use a microwave on low power or reheat them in a skillet over medium-low heat until heated through.
  7. Consider Freezing for Longer Storage:
    • If you want to store French Onion Soup Burgers for an extended period, you can freeze them individually. Wrap each burger tightly in plastic wrap or aluminum foil and place them in a freezer-safe container. Thaw overnight in the refrigerator before reheating.

  3. French Onion Soup Slider Trio:
