Place a heavy skillet (cast iron works great) over high heat and allow it to get smoking hot. Preheat your oven to a low temperature (around 200°F) to keep the cooked burgers warm.
Prepare the Patties
Divide your ground beef into equal portions, typically about 1/4 to 1/3 pound each. Avoid overworking the meat; gently form them into loose balls, and season generously with salt and pepper on both sides.
Smash the Patties
Once the skillet is hot, place a portion of ground beef onto the skillet. Use a flat spatula or a burger smasher to press down firmly on the patty to flatten it against the skillet. Press until it’s about 1/4 inch thick or so.
Sear the Patties
Let the patties cook without moving them for about 2-3 minutes. This allows the crust to form. You should see the edges start to brown and crisp up.
Flip the Patties
Using a spatula, carefully flip the patties. If you’re adding cheese, now is the time to place a slice on top of each patty. Cook for an additional 1-2 minutes for medium-rare to medium doneness, depending on your preference and the thickness of the patties.
Assemble the Burgers
Transfer the cooked patties to toasted hamburger buns. Add your desired toppings and condiments.
Serve Hot
Smashed burgers are best enjoyed immediately while they’re hot and juicy.
Repeat
Continue the process with the remaining portions of ground beef until all the burgers are cooked.
