Instructions
In a large mixing bowl, season the ground beef with kosher salt and black pepper. Mix just until combined—overworking can toughen the meat.
Divide the meat into four equal 1/4 lb portions. Shape into wide, flat patties (larger than the bun, as they shrink when cooking). Press a slight indent into the center of each to prevent doming.
Preheat a cast iron skillet or grill over medium-high heat (about 400°F / 204°C). Do not oil the pan—rely on beef fat for searing.
Place the patties onto the hot surface. Cook for 2-3 minutes per side for medium, or until a crust forms and juices begin to rise to the surface. Avoid pressing down to retain juiciness.
About 30 seconds before removing from heat, place one slice of American and one slice of Swiss cheese on each patty and cover the pan with a lid or foil to melt the cheese.
Lightly toast the buns cut-side down in the same pan or in a toaster until golden (about 1 minute).
To Assemble: Spread mayonnaise on both bun halves. Add ketchup and mustard to the top bun. Place one cheese-covered patty on the bottom bun, followed by a second patty. Cap with the top bun.

Notes
Add crispy bacon or grilled onions for a personalized touch of umami.
Swap out one cheese for pepper jack if you want a little kick.
For a leaner version, use ground turkey and low-fat cheese, but note the texture and taste will differ from the original.
