These Cast Iron Onion Burgers are so juicy! Topped with melted cheese, horseradish sauce and onions, this is one burger recipe you won't want to miss.
Servings 4 burgers
- 1 pound ground hamburger
- 1 Tbs Worcestershire Sauce
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 Tbs A1 Sauce
- 1 Tbs A1 Dry Rub
- 4 hamburger buns
- 2 Tbs butter
- 1 large yellow onion cut into thick slices
- 4 slices cheddar cheese
- 4 tsp oil
- 1/4 cup mayonnaise
- 1/4 cup horseradish sauce
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.
Place the cast iron skillet on the stove top and heat on medium/high for 3-4 minutes to get it good and hot.
Add oil to the pan. Place onions let sizzle for a few seconds then place burger on top.
To cook the burger as evenly as possible cover with a lid. Cook 8 minutes, that was the 'sweet spot' on medium heat.
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.
Take the buns and smother in some butter and cook on a sheet pan for around 5 minutes.
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!
