Cast Iron Onion Burgers | Bottom Left of the Mitten
Instructions
  1. Take the ground hamburger and add Worcestershire Sauce, A1 Sauce, salt and pepper and mix. Form into 4 patties. Shake the dry rub on top.
  2. Place the cast iron skillet on the stove top and heat on medium/high for 3-4 minutes to get it good and hot.
  3. Add oil to the pan. Place onions let sizzle for a few seconds then place burger on top.
  4. To cook the burger as evenly as possible cover with a lid. Cook 8 minutes, that was the ‘sweet spot’ on medium heat.
  5. Flip over so the onions are on top. Cook 6 minutes. Add cheese then cover again and cook an additional 2-3 minutes to melt.
  6. Take the buns and smother in some butter and cook on a sheet pan for around 5 minutes.
  7. Whip together mayonnaise and horseradish sauce. Top the toasted bun with the burger. Smother as much as you like of the sauce on the bun. Enjoy!
