Burger Patties & Seasoning

Assembly & Condiments

Method

Burger Patties & Cooking

  1. 1

    Shape patties

    Divide the ground beef into 4 equal portions (about 4 oz each). Gently form each portion into a patty about ¾-inch thick, handling the meat as little as possible. Make a shallow dimple in the center of each patty with your thumb to help them cook evenly.

  2. 2

    Season

    Season both sides of each patty with kosher salt and freshly ground black pepper just before cooking.

  3. 3

    Cook patties

    Heat a large skillet or cast-iron pan over medium-high heat until hot. Add 1 tablespoon vegetable oil and swirl to coat. Place patties in the pan without crowding (work in batches if needed). Cook for 3-4 minutes on the first side until a brown crust forms. Flip and cook another 3 minutes for medium (adjust to desired doneness). In the last minute of cooking, place a slice of Swiss cheese on each patty, cover the pan, and allow the cheese to melt for about 1 minute. Transfer cooked patties to a plate and tent loosely with foil to rest.

Sautéed Mushrooms & Onions

  1. 4

    Prepare vegetables

    Clean mushrooms with a damp towel and slice them about ¼-inch thick. Thinly slice the onion and mince the garlic.

  2. 5

    Sauté

    In a large skillet, heat 1 tablespoon unsalted butter and 1 teaspoon olive oil over medium-high heat. Add the sliced onions and cook, stirring occasionally, for 4-5 minutes until they begin to soften and turn translucent. Add the sliced mushrooms and continue to cook, stirring occasionally, until the mushrooms release their liquid and it evaporates, about 6-8 minutes. Add the minced garlic and fresh thyme (if using) and cook for 30-45 seconds until fragrant.

  3. 6

    Season mushrooms & onions

    Season the mixture with 1 teaspoon salt and ½ teaspoon black pepper. Taste and adjust seasoning. Remove from heat and keep warm until assembly.

Assembly & Finishing

  1. 7

    Toast buns

    Spread the softened butter evenly on the cut sides of the buns. In a clean skillet over medium heat, toast the buns cut-side down until golden and slightly crisp, about 1-2 minutes. Alternatively, toast under a broiler for 1 minute watching closely.

  2. 8

    Spread mayo

    Evenly spread about 1 tablespoon mayonnaise on the bottom half of each toasted bun (use the remaining mayo on top halves if desired).

  3. 9

    Assemble burgers

    Place a lettuce leaf on each mayo-coated bottom bun. Top with a Swiss-topped beef patty, then spoon a generous portion (about ¼ cup) of the sautéed mushrooms and onions over the cheese. Finish with the top bun.

  4. 10

    Serve

    Serve the mushroom burgers hot with your choice of sides. If desired, offer extra mayonnaise or mustard on the side.
