Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
Make the Meatball Mixture
In a large mixing bowl, combine the ground lamb, harissa paste, parsley, mint, breadcrumbs, egg, garlic, cumin, coriander, smoked paprika, salt, and black pepper. Mix gently with your hands until just combined—don’t overmix!
Shape the Meatballs
Roll the mixture into golf-ball-sized meatballs (about 1 1/2 inches in diameter). Place them on the prepared baking sheet, spacing them slightly apart.
Bake the Meatballs
Bake for 20-25 minutes, or until the meatballs are cooked through and slightly browned on the outside. Flip the meatballs halfway through the baking process to ensure they are evenly browned.
Prepare the Herbed Yogurt Sauce
While the meatballs bake, whisk together the Greek yogurt, dill, parsley, lemon juice, lemon zest, and garlic in a small bowl. Season with salt and pepper to taste. Chill in the fridge until ready to serve.
Serve and Enjoy
Serve the meatballs warm with the herbed yogurt dipping sauce on the side. Garnish with extra parsley or mint for a fresh touch.
