Ingredients:
- 2 lbs ground beef (80/20 chuck blend)
- 1 tsp kosher salt
- 1 tsp freshly cracked black pepper
- 1 tbsp neutral oil
- 6 slices sharp cheddar or American cheese
- 6 brioche buns, split
- 3 large leaves of Romaine lettuce, torn
- 1 large tomato, sliced thin
- 1 small red onion, thinly sliced
- 1/2 cup mayonnaise
- 1 tbsp yellow mustard
- 1 tbsp pickle relish
- 1/2 tsp paprika
Instructions:
- Shape the beef. Gently divide the ground beef into 6 equal portions. Lightly shape them into disks about 3/4 inch thick. Note: Do not overwork the meat or it will become tough.
- Create the indent. Press a small indentation into the center of each patty with your thumb. Note: This prevents the burger from puffing up into a ball.
- Season the meat. Sprinkle the kosher salt and black pepper generously on both sides immediately before cooking. Note: Salting too early draws out moisture and ruins the sear.
- Heat the pan. Add 1 tbsp neutral oil to a cast iron skillet over medium high heat until the oil is shimmering.
- Sear the patties. Place the patties in the pan. Cook 3-4 mins until a deep brown crust forms. Do not move or press them.
- Flip and finish. Flip once and cook for another 3 mins, or until the internal temperature reaches 155°F (68°C) for medium.
- Steam melt the cheese. During the final 60 seconds, place a slice of cheese on each patty. Pour 1 tsp of water into the pan and cover immediately with a lid until the cheese is velvety and melted.
- Toast the buns. Remove the burgers. Place the split brioche buns in the residual beef fat in the skillet and toast until golden brown.
- Whisk the sauce. In a small bowl, mix mayonnaise, yellow mustard, pickle relish, and paprika until smooth.
- Assemble. Slather the bottom bun with sauce, add Romaine, the cheesy patty, tomato, red onion, and the top bun.
