In a mixing bowl, combine the ground lamb, chopped red onion, minced garlic, fresh mint, ground cumin, smoked paprika, salt, and pepper. Mix everything thoroughly, but try not to overwork the mixture to keep the patties tender.
Divide the lamb mixture into equal portions and shape them into burger patties. Aim for patties about 1/2-inch thick.
Preheat your air fryer to 375°F (190°C) for a few minutes.
Brush the lamb patties with a little olive oil on both sides. This will help them develop a nice crust during cooking.
Place the patties in a single layer in the air fryer basket, leaving some space between each one.
Cook for about 8-10 minutes, flipping the patties halfway through the cooking time. The exact time may vary depending on your air fryer's model and the thickness of the patties.
Lamb should be cooked to an internal temperature of 160°F (71°C) for medium doneness. Adjust the cooking time accordingly for your desired level of doneness.
While the lamb burgers are cooking, prepare your favorite burger buns and gather your preferred toppings and condiments.
When the burgers are done, remove them from the air fryer.
Place each lamb burger on a bun and add your chosen toppings and condiments.
Serve immediately, and enjoy your delicious, homemade Air Fryer Lamb Burgers!
