Prepare the Ingredients
Using a santoku or chef's knife and cutting board, thinly slice 1 large sweet onion.
Shape 2 pounds lean ground beef into patties and place on a baking sheet. Season with 1 teaspoon seasoned salt, 1/2 teaspoon garlic powder and 1/2 teaspoon onion powder, and 1/2 teaspoon freshly ground black pepper. Allow the burger to come to room temperature.
When grilling burgers, I like to poke a hole in the center of the patties, which helps the burger to cook evenly.
Caramelize the Onions
Heat a large skillet over medium heat and melt 3 tablespoons butter and 1 tablespoon olive oil. Add the sliced onions and cook until browned and softened, approximately 8-10 minutes. Stir often.
Stir in 1/4 cup balsamic vinegar and 2 teaspoons brown sugar. Continue cooking the onions until they caramelize, about 2-3 minutes more. Season with 1/2 teaspoon kosher salt and 1/2 teaspoon freshly ground black pepper.
Transfer the onions to a plate or bowl to use when assembling the burgers.
Grill the Burgers
When the charcoal is nearly all grey, place the ground beef patties on the hot grill. Close the lid and allow the burgers to cook for 5 minutes and then turn. Continue this process until the meat is cooked to your satisfaction.
Ground beef is fully cooked when the internal temperature reaches 160℉. Also keep in mind that the meat will continue to cook as it cools.
Toast 4 each wheat hamburger buns by spreading 4 tablespoons butter on the inside of each and cooking on a hot griddle or the grill until lightly browned. Keep warm until burgers are ready to assemble.
Prepare the Garlic Mayo
While the burgers cook on the grill, prepare the garlic mayo sauce. In a small bowl, combine 4 tablespoons mayonnaise, 4 tablespoons ketchup, 2 tablespoons minced garlic, and 5 drops siracha sauce. Taste and season as desired. Set aside until time to assemble the burgers
Assemble the Burgers
When the meat has nearly cooked to your satisfaction, top patties with 4 slices Gouda Cheese. Cook for 1-2 additional minutes until the cheese has melted.
Allow hamburger patties to cool on a plate or platter for 4-5 minutes. Then place burgers on toasted hamburger buns.
Top each burger with caramelized onions and 1-2 tablespoons of garlic mayo. Add dill pickles, if desired.
This recipe will serve 4-6 people.
