How can I make a juicy hamburger?

To make a juicy hamburger, start with high-quality ground beef that has some fat content for flavor. Season the meat with salt, pepper, and any other desired seasonings. Form the patties gently, making an indentation in the center to prevent them from puffing up while cooking. Cook the patties on a hot grill or skillet, flipping only once. Let the burgers rest for a few minutes before serving to allow the juices to redistribute, resulting in a juicy and flavorful hamburger.
