Cooking Instructions

  1. 1

    Caramelize the Onions

    Heat olive oil in a skillet over medium heat. Add sliced onions and cook for about 5 minutes until they start to soften.

  2. 2

    Add Vermouth

    Pour the vermouth over the onions, reduce heat to low, and continue to cook, stirring occasionally, until the onions are golden brown and caramelized, about 15-20 minutes. Season with salt and pepper.

  3. 3

    Prepare the Patties

    While the onions are caramelizing, divide the ground beef into two equal portions and shape them into patties. Season both sides with salt and pepper.

  4. 4

    Cook the Patties

    In another skillet or grill, cook the patties over medium-high heat for about 4-5 minutes on each side, or until they reach your desired doneness.

  5. 5

    Add Cheese

    In the last minute of cooking, place two slices of cheddar cheese on each patty and cover to melt.

  6. 6

    Assemble the Burger

    Toast the burger buns if desired. Place each cheesy patty on a bun, top with the caramelized onions, and add the top bun.

  7. 7

    Serve

    Serve the Blacklock Burger with your favorite sides and enjoy!
