Ingredients

  • 8 oz Ground Beef (80/20, grass‑fed) (Form into one ½‑lb patty, keep at room temperature)
  • 1 medium Yellow Onion (Thinly slice paper‑thin (mandoline or sharp knife))
  • 3 slices Dill Pickles (Slice lengthwise)
  • 1 tsp Yellow Mustard (Classic American mustard)
  • 0.5 tsp Salt (Kosher or regular)
  • 0.25 tsp Black Pepper (Freshly ground)
  • 0.25 tsp Pork Salt (Optional, adds a subtle porky flavor)
  • 1 piece Burger Bun (7‑inch soft roll, toasted on grill)
  • 1 tsp Butter (For toasting the bun)

Instructions

  1. Slice Onions

    Using a sharp knife or mandoline, slice the yellow onion as thinly as possible (paper‑thin). Place slices in a small bowl.

    Time: PT5M

  2. Form Beef Patty

    Shape the 8 oz of ground beef into a patty slightly larger than the bun; make a small indentation in the center to prevent puffing.

    Time: PT3M

  3. Season Patty

    Season both sides of the patty with salt, pepper, and pork salt.

    Time: PT2M

  4. Preheat Cooking Surface

    Heat the grill or cast‑iron skillet over medium‑high heat until it reaches about 400°F.

    Time: PT5M

    Temperature: 400°F

  5. Fry Thin Onions

    Add a thin layer of oil (or use a splash of beef drippings) to the hot surface and spread the onion slices in a single layer. Fry, stirring occasionally, until golden and crisp, about 3‑4 minutes.

    Time: PT4M

    Temperature: 350°F

  6. Grill the Patty

    Place the seasoned patty on the hot grill. Cook 4 minutes on the first side, then flip and cook another 4 minutes for medium doneness. Do not press the patty.

    Time: PT8M

    Temperature: 400°F

  7. Toast the Bun

    Brush the cut side of the bun with butter and place it butter‑side down on the grill for 1‑2 minutes until lightly browned.

    Time: PT2M

    Temperature: 400°F

  8. Assemble the Burger

    On the bottom bun, place the cooked patty, then pile the crispy fried onions on top. Add dill pickle slices and a drizzle of yellow mustard. Top with the toasted bun half.

    Time: PT2M
