01 -
2 large sweet onions, peeled, halved, and thinly sliced
02 -
8 tablespoons unsalted butter, divided
03 -
1/3 cup mayonnaise
04 -
2 tablespoons ketchup
05 -
1/2 teaspoon yellow mustard
06 -
1/4 teaspoon garlic powder
07 -
1/4 teaspoon ground black pepper
08 -
4 Chop House by Holten Angus Sirloin Steak Burgers
09 -
8 slices thick-cut sourdough or rye bread
10 -
4 slices medium cheddar cheese
11 -
4 slices Swiss cheese
# Steps:
01 -
In a large skillet, melt 2 tablespoons of butter over medium-low heat. Add the onions and cook over low heat, stirring occasionally, until they are golden and soft—about 30 minutes.
02 -
Make the sauce by combining the mayonnaise, ketchup, mustard, garlic powder, and black pepper. Set aside.
03 -
Heat a large cast iron skillet over medium-high heat. Add 2 tablespoons of butter, then cook the burger patties according to the package instructions. Wipe the skillet clean.
04 -
Spread the prepared sauce on one side of all 8 slices of bread. Divide the caramelized onions between 4 slices of bread. Top each slice with a burger patty, one slice of cheddar cheese, one slice of Swiss cheese, and a second slice of bread.
05 -
Add 2 tablespoons of butter to a skillet over medium-low heat and swirl to coat the pan. Add the assembled sandwiches and cook until the bread is golden brown, then flip the sandwiches. Add the remaining 2 tablespoons of butter to the skillet, moving the sandwiches around to coat them evenly in butter. Cook until the second side is golden brown. Serve immediately.
