Ingredients
Scale
For the Balsamic Mayo Spread
- 1/2 cup Mayo
- 1 tablespoon Balsamic vinegar
For the Caramelized Onions
- 2 tablespoons Extra virgin olive oil
- 2 large Sweet yellow onions, sliced
- 1 teaspoon Kosher salt
- 1/2 teaspoon Ground black pepper
For the Burger Patties
- 1 pound Ground beef
- 1 teaspoon Kosher salt
- 1/2 teaspoon Ground black pepper
For Assembly
- 4 pieces Hamburger buns
- 4 slices American cheese
- 4 slices Bacon, cooked crispy
- 1/2 cup Burger pickles
- 1 cup Romaine lettuce, washed and trimmed
Instructions
- Make the Balsamic Mayo: In a small bowl, combine 1/2 cup mayo with 1 tablespoon balsamic vinegar. Stir well until fully incorporated. Cover and refrigerate to let the flavors meld.
- Caramelize the Onions: Heat a cast iron skillet over medium-high heat and add 2 tablespoons of extra virgin olive oil, swirling to coat. Add the sliced sweet yellow onions, sprinkle with 1 teaspoon kosher salt and 1/2 teaspoon ground black pepper. Reduce heat to medium-low and cook slowly, stirring occasionally, for 15 to 30 minutes until onions turn a deep golden brown and become sweet and tender.
- Preheat the Grill: While the onions caramelize, preheat your grill to medium-high heat to prepare for cooking the patties.
- Prepare the Patties: In a mixing bowl, combine the ground beef with 1 teaspoon kosher salt and 1/2 teaspoon ground black pepper. Divide the mixture into 4 equal portions and shape each into a patty. Make a slight indent in the center of each patty to help it cook evenly. Season the tops with a little extra salt and pepper.
- Grill the Patties: Place the patties on the preheated grill and cook for 3 to 4 minutes on each side for medium doneness. During the last 1 to 2 minutes of cooking, top each patty with a slice of American cheese to melt.
- Assemble the Burgers: Toast the hamburger buns lightly if desired. On the bottom bun, place a lettuce leaf, then the cheese-topped beef patty, a generous spoonful of caramelized onions, several slices of crispy bacon, and burger pickles. Spread the prepared balsamic mayo on the top bun and complete the burger.
- Serve: Serve the assembled burgers immediately while the patties are hot and the cheese is melted. Pair with your favorite sides for a complete meal.
Notes
- Caramelizing onions slowly over low heat is key to developing their rich, sweet flavor without burning.
- Making a small indent in the center of burger patties helps them cook evenly and prevents puffing up in the middle.
- Feel free to substitute your preferred cheese or add additional toppings such as tomato slices or avocado.
- Ensure the grill is hot before adding patties to get a nice sear and lock in juices.
- Use a cast iron skillet for the best caramelization results with the onions.
