To cook a burger to the perfect temperature with a great crust, use the smash burger technique: smash the patty thin on a hot cast iron skillet, cook for a few minutes per side until a crust forms, and monitor the internal temperature with a meat thermometer. For medium-rare, aim for 130-135°F.
Achieving a perfect burger involves a combination of technique and temperature control. Here's a step-by-step guide:
Choose Your Ground Beef: Opt for ground beef with a fat content of around 80/20 (80% lean, 20% fat). The fat is crucial for flavor and moisture.
Prepare the Patty: Gently form the ground beef into a loose ball. Avoid overworking the meat, as this can result in a tough burger.
Heat Your Pan: Use a heavy-bottomed skillet, preferably cast iron. Heat it over medium-high heat until it's very hot. A hot pan is essential for developing a good crust.
Smash the Burger: Place the beef ball in the hot pan and immediately smash it down with a sturdy spatula. Aim for a thin patty, about 1/4 to 1/2 inch thick. This increases the surface area in contact with the hot pan, maximizing crust formation.
Season Generously: Season the patty with salt and pepper immediately after smashing it. Don't be shy with the seasoning; it's crucial for flavor.
Cook the First Side: Let the burger cook undisturbed for 2-3 minutes. You should see a dark brown crust forming around the edges.
Flip and Cook the Second Side: Carefully flip the burger and cook for another 1-3 minutes, depending on your desired doneness. For medium-rare (130-135°F), 1-2 minutes is usually sufficient.
Check the Temperature: Use a meat thermometer to ensure the burger reaches your desired internal temperature. Insert the thermometer into the thickest part of the patty.
Add Cheese (Optional): If you want cheese, add it during the last minute of cooking and cover the pan to help it melt.
Rest Briefly: Remove the burger from the pan and let it rest for a minute or two before serving. This allows the juices to redistribute, resulting in a more tender and flavorful burger.
Avoid pressing down on the burger after the initial smash. Pressing releases juices and can dry out the burger. Let it cook undisturbed to develop a proper crust.
