To ensure that hamburgers are safe to eat and cooked to the right tenderness and juiciness, they should be cooked to an internal temperature of 160°F (71°C) . This temperature applies to store-bought ground beef, which must be cooked to this temperature to ensure that any bacteria living on the outside of the meat are destroyed and to prevent foodborne illness. If you grind your own meat to make burgers, you should also cook the ground beef to 160°F (71°C) to ensure that any bacteria are destroyed and to achieve the best cooking temperature.

Its important to note that burgers will continue to cook after being removed from the heat source due to residual heat, so its recommended to pull the burgers at 155°F (68°C) to achieve the best temperature possible.

Here are some additional tips for cooking hamburgers:

• Use a meat thermometer to check the internal temperature of the burgers.
• Burgers should be cooked at medium-high to high heat, meaning somewhere between 350 and 400 degrees Fahrenheit.
• Cook the burgers away from the heat with the grill lid closed until their temperature reaches 135°F (57°C), then sear them to your desired temperature.
• For thicker burgers, use medium heat to cook them.
• Season the burgers with salt and pepper just before cooking.
• Dont press on the burgers while cooking.
• Let the burgers rest for about 5 minutes after cooking to allow the juices to redistribute.

By following these tips and cooking hamburgers to an internal temperature of 160°F (71°C), you can ensure that your burgers are safe to eat and cooked to perfection.
