Beef Patties

Method

Beef Patties

  1. 1

    Mix and portion

    Place the ground chuck in a large bowl. Add kosher salt, black pepper, Worcestershire sauce, garlic powder, and onion powder. Gently combine with your hands or a spatula until just mixed—do not overwork. Divide the meat into two equal portions (about 10 oz / 280 g each).

  2. 2

    Form patties

    Shape each portion into a thick patty about 3/4 to 1 inch thick and roughly the diameter of your buns (they will shrink slightly). Press a shallow dimple into the center of each patty with your thumb to help them cook evenly.

  3. 3

    Preheat and oil

    Heat a cast-iron skillet or griddle over medium-high heat until very hot (about 5 minutes). Add the neutral oil and swirl to coat.

  4. 4

    Cook patties

    Place patties in the hot skillet. Cook without moving for 3-4 minutes to develop a brown crust. Flip and cook the other side 3 minutes for medium-rare to medium, or longer to desired doneness. In the last 60 seconds of cooking, place a slice of cheddar on each patty and cover the pan for 30–60 seconds to melt.

Bacon & Vegetables

  1. 5

    Cook bacon

    While patties cook, place bacon in a separate cold skillet in a single layer. Turn heat to medium and cook, turning occasionally, until crisp (about 8–10 minutes). Transfer to paper towels to drain.

  2. 6

    Prepare vegetables

    Thinly slice the red onion into rings. Slice the tomato into 1/4-inch thick rounds. Wash and dry lettuce leaves. Have dill pickle slices ready.

Buns & Sauce

  1. 7

    Make the Brontosaurus sauce

    In a small bowl combine mayonnaise, ketchup, yellow mustard, smoked paprika, and hot sauce if using. Stir until smooth and taste; adjust seasoning with a pinch of salt if desired.

  2. 8

    Toast buns

    Spread 1 tbsp unsalted butter on the cut sides of each bun half. Place buttered sides down in a skillet over medium heat and toast until golden brown, about 1–2 minutes. Remove from heat.

Assemble & Serve

  1. 9

    Spread a generous tablespoon of Brontosaurus sauce on the bottom half of each toasted bun. Place a leaf or two of lettuce on the sauce to act as a moisture barrier.

  2. 10

    Set the cheddar-topped patty on the lettuce. Top each patty with two slices of crisp bacon, a couple of tomato slices, a few red onion rings, and three pickle slices.

  3. 11

    Spread a little sauce on the top bun, close the burger, and press gently to set. Serve immediately with fries or a side salad.
