The grilling time for burgers depends on the desired level of doneness, the thickness of the patty, and the grill temperature. Here are general guidelines for 1-inch thick patties cooked on a medium-high heat grill (around 375-500°F):

• Rare: About 4 minutes total (2 minutes per side), reaching an internal temperature of 125°F to 130°F.
• Medium-rare: About 5 to 6.5 minutes total (2.5 to 3.25 minutes per side), with an internal temperature of 130-135°F.
• Medium: About 6 to 8 minutes total (3 to 4 minutes per side), reaching 140-145°F.
• Medium-well: Around 9 minutes total, internal temperature 150-155°F.
• Well-done: About 9 to 10 minutes total (4.5 to 5 minutes per side), with an internal temperature of 160°F or higher, which is recommended by the USDA for safety

For charcoal grills, cook patties directly over the coals for about 4-5 minutes per side, then move to indirect heat to finish cooking to the desired doneness

. Use a meat thermometer inserted through the side of the patty for the most accurate reading. Avoid pressing down on the burgers while grilling to retain juiciness

. After grilling, let burgers rest for a few minutes before serving to allow juices to redistribute

. In summary, plan on grilling burgers for about 4 to 10 minutes total depending on how well done you want them, flipping once halfway through. Always aim for an internal temperature of at least 160°F for food safety, especially with ground beef
