Ultimate Stacked Cheeseburger with Caramelized Onions

Ultimate Stacked Cheeseburger with Caramelized Onions

Ingredients:

• For the Burger Patties:
  • 1.5 lbs (680 g) ground beef (80/20 blend for juiciness)
  • Salt and pepper, to taste
  • 4 slices cheddar cheese
  • 4 slices Swiss cheese
• For the Caramelized Onions:
  • 2 large onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon sugar (optional, to enhance sweetness)
  • 1/2 teaspoon salt
  • 1 tablespoon balsamic vinegar (optional, for added depth of flavor)
• For the Assembly:
  • 4 sesame seed burger buns (sesame and black sesame mix for extra flavor)
  • 2 cups fresh arugula or mixed greens
  • Your favorite burger condiments (ketchup, mustard, mayo, etc.)
  • Pickles (optional)
  • Crispy bacon (optional, for an extra layer of flavor)

Instructions:

1. Prepare the Caramelized Onions:
   • In a large skillet, heat the butter and olive oil over medium heat.
   • Add the sliced onions and cook, stirring occasionally, until they start to soften, about 5-7 minutes.
   • Sprinkle in the sugar (if using) and salt, and continue cooking for another 20-25 minutes, stirring frequently, until the onions are deeply browned and caramelized.
   • Stir in the balsamic vinegar, if using, and cook for an additional 2-3 minutes.
   • Remove from heat and set aside.
2. Cook the Burger Patties:
   • Divide the ground beef into 4 equal portions and gently shape each portion into a thin patty, about 4-5 inches in diameter. Avoid overworking the meat to keep the patties tender.
   • Season each patty with salt and pepper on both sides.
   • Heat a grill or a large skillet over medium-high heat.
   • Cook the patties for about 3-4 minutes on the first side, then flip.
   • Immediately add a slice of cheddar cheese on two patties and Swiss cheese on the other two, allowing the cheese to melt as the patties finish cooking, another 3-4 minutes.
3. Toast the Buns:
   • While the patties are cooking, lightly toast the burger buns on the grill or in a separate skillet until golden brown.
4. Assemble the Burgers:
   • Place a generous handful of arugula or mixed greens on the bottom half of each bun.
   • Place one patty with cheddar cheese on the greens, followed by a patty with Swiss cheese.
   • Top the stack with a heaping spoonful of caramelized onions.
   • Add any additional toppings you like, such as pickles, crispy bacon, or condiments.
   • Finish with the top half of the bun.
5. Serve:
   • Serve the burgers immediately with your favorite sides like fries, sweet potato fries, or a simple salad.
