Lamb burgers are such a delicious, great alternative to traditional beef patties! Mix with fresh herbs, garlic, and seasonings for an incredibly flavorful burger.
In a medium bowl, combine the ground lamb, garlic, chopped mint, dried mint, salt and pepper. Do not overwork the mixture; it's okay if the meat has a just-ground look to it rather than a smooth look, to keep the burgers from becoming too dense.
Divide the mixture into four meatballs (about 4 oz. each), again without overworking the meat (these should not be smooth). Gently flatten each ball to about an inch thick, and collect back to the patties any meat that may be falling away from the patties. If making ahead, cover and chill these for up to 2 days (bring to room temp before cooking).
Coat the cooking surface with the oil before heating. Heat a skillet, griddle, or grill to medium high. Cook the patties until they are cooked through to 160°F, flipping them over halfway through cooking (6-8 minutes total, depending on the thickness of the patties). Cook the burgers couple or even one at a time if needed, depending on the size of your cooking surface.
Layer the bottom half of each bun with lettuce, onion, and tomato. Place a patty on each. Top each patty with a dusting of dried and fresh mint. Top with sauce and serve immediately.
