1-2tablespoonscornstarch and waterfor thickening if needed (optional)
Instructions
Preheat the grill to 450°F or medium heat. Season beef patties on both sides with salt and pepper. Set aside a ½ cup of bbq sauce for serving. Grill burgers for 4 minutes per side, basting with remaining sauce as they cook. Burgers should reach an internal temperature of 165°F. Any sauce left after basting burgers should be discarded.
Meanwhile, place pineapple slices on grill and cook until lightly caramelized, approximately 2 minutes per side.
Place two slices of pepper jack cheese per burger patty and cook for another minute or until cheese has melted.
Place burgers on buns with a pineapple slice and red onion. Serve with reserved bbq sauce.
Huli Huli Sauce (Hawaiian BBQ Sauce)
Place all ingredients in a small saucepan and bring to a simmer. Cook for 5 minutes.
Once cooled, if the sauce is too thin, whisk together equal parts water and cornstarch in a small bowl. Add the mixture to the barbecue sauce and rewarm to activate the thickening properties of the cornstarch.
