Ingredients
- ¼cup mayonnaise
- ¼cup ketchup
- 2teaspoons Dijon or yellow mustard
- Salt and black pepper
- 20scallions (about 4 bunches), root ends trimmed
- 1pound ground beef (preferably 20 percent fat)
- 2tablespoons avocado oil, sunflower seed oil or grapeseed oil
- 4slices American cheese
- 4burger buns
Preparation
- Step 1
In a small bowl, combine the mayonnaise, ketchup, mustard and a pinch each of salt and pepper.
- Step 2
Prep the scallions: Trim the scallion tips, then cut scallions crosswise into thirds; cut each segment very thinly lengthwise.
- Step 3
Divide the beef into 4 equal portions; shape each into a 4-inch-wide patty. Season generously with salt and pepper all over.
- Step 4
Heat a large cast-iron pan or griddle over medium-high until smoking. Add the oil and place one or two beef patties in the pan, depending on space. (The patties will be about 5 inches wide once they’re smashed.) Pile about ¼ of the scallions on top of each patty. (They will significantly reduce in volume as they cook.)
- Step 5
Using a grill press or spatula, firmly smash each patty, pressing the scallions into the meat until patties are about 5 inches wide. Cook, undisturbed, for 2 minutes, until the meat develops a dark brown crust on the bottom. Flip each smashed patty, top with cheese and loosely perch the top and bottom buns on top to warm through. Cook until the cheese melts, the patty develops a crust underneath and the buns warm through, 1 to 2 minutes. Repeat to prepare remaining burgers.
- Step 6
To serve, brush the burger buns with a dollop of sauce. Place a patty in each burger bun and top with any additional crispy charred scallions from the pan.
