Prepare the Lamb Patties. In a large mixing bowl, combine the ground lamb, finely chopped onion, minced garlic, fresh rosemary, ground cumin, ground coriander, paprika, salt, and pepper. Gently mix the ingredients together until well combined, being careful not to overwork the meat. Overmixing can result in dense burgers.
Shape the Patties. Divide the lamb mixture into equal portions, depending on the desired size of your burgers. Shape each portion into a patty, using your hands to form them into round discs of even thickness. Press a slight indentation into the center of each patty to prevent it from puffing up during cooking.
Preheat the Skillet. Preheat a skillet on the stovetop over medium-high heat. Make sure the cooking surface is well-oiled to prevent the lamb patties from sticking.
Pan-Sear the Patties. Place the lamb patties on the preheated skillet and cook for about 4-5 minutes per side, or until they reach your desired level of doneness. For medium-rare, cook until the internal temperature reaches 145F. Adjust the cooking time according to your preference for doneness.
Toast the Burger Buns. While the patties are cooking, you can toast the burger buns on the grill or in a toaster until lightly golden. Toasting adds a nice crunch and helps prevent the buns from becoming soggy when topped with condiments.
Assemble the Lamb Burgers. Remove the cooked lamb patties from the grill or skillet and allow them to rest for a few minutes. This helps the juices redistribute and keeps the burgers moist. Assemble the burgers by placing the patties on the toasted buns and adding your desired toppings.
Serve and Enjoy! Now, it's time to savor the mouthwatering delight of homemade lamb burgers. Sink your teeth into the juicy patty with its tantalizing blend of flavors.
