Notes
Preheat your oven to the recommended temperature for baking burgers. This ensures that the patties start cooking immediately. Place a baking sheet or oven-safe pan in the oven while it preheats. This helps to achieve a seared effect on the burgers.
Keep a close eye on the burgers as they cook. Cooking times can vary based on the thickness of the patties and the oven temperature. Use a meat thermometer to check for doneness and ensure that the internal temperature of the burgers reaches 160F.
Allow your oven-baked burger patties to rest for a few minutes after removing them from the oven. This helps retain juices and enhances the overall flavor.
