FOR THE ONIONS:
- 1 tbsp. butter
- 1 large onion (thinly sliced)
- Kosher salt
FOR THE SAUCE:
- 2 tablespoons mayonnaise
- 1 tablespoon ketchup
- 1 tablespoon sweet pickle relish
- 1/2 tsp. white vinegar
- 1 pinch sugar
- sea salt to taste
FOR THE BURGERS:
- 1 lb. ground beef (80/20 blend)
- Kosher salt
- Freshly ground black pepper
- 6 slices American cheese
- 4 tbsp. yellow mustard
- 3 potato buns (toasted)
- Iceberg lettuce
- 1 tomato (sliced)
- 4 pickles
Prepare the Special Sauce
In a small bowl, mix together mayonnaise, ketchup, sweet pickle relish, white vinegar, sugar, and a pinch of salt. Adjust the seasoning to taste. Set aside.
Shape the Patties
Divide the ground beef into 8 equal portions and form them into thin patties slightly larger than the buns. Season both sides with salt and pepper.
Cook the Patties
Heat a skillet or griddle over medium-high heat. Cook the patties for about 2-3 minutes on one side. Flip, and immediately place a slice of cheese on 4 of the patties. Cook for another 2 minutes or until the cheese is melted and the patties are cooked to your preferred doneness.
Prepare the Grilled Onions
Preheat the Skillet: Heat a skillet or frying pan over medium heat. Add butter or oil to coat the bottom of the skillet.
Add Onions: Once the butter has melted or the oil is hot, add the thinly sliced onions to the skillet. Spread them out evenly across the surface.
Season: Sprinkle a pinch of salt over the onions. This will help draw out moisture and caramelize the onions.
Cook Slowly: Reduce the heat to low. Let the onions cook slowly, stirring occasionally. The key to perfect grilled onions is patience; they should soften and become golden brown without burning. This process can take about 15-20 minutes depending on your stove and skillet.
Stir Occasionally: Keep an eye on the onions and stir them every few minutes to ensure they cook evenly and don’t stick to the bottom of the pan.
Finish: Once the onions have turned a rich golden color and are caramelized, remove them from the heat. Taste and adjust the seasoning with more salt if needed.
Toast the Buns
Cut the buns in half and toast them lightly on the skillet or griddle, cut side down, until golden brown.
Assemble the Burgers
On the bottom bun, spread a generous amount of the special sauce. Add a slice of lettuce, followed by a slice of tomato, and a few slices of pickles. Place a cheese-topped patty on the pickles, then add an onion slice. Top with a second patty (without cheese), more special sauce if desired, and finish with the top bun.
