How to Make It
In a blender, pulse the rosemary and garlic cloves with a pinch each of salt and pepper until coarsely chopped. With the machine on, gradually add the 1/2 cup of olive oil until the rosemary and garlic are finely chopped. Scrape the mixture into a large baking dish and add the lamb chops. Turn the chops so they are well coated. Refrigerate for at least 2 hours or overnight.
Light a grill or preheat a grill pan. Season the lamb chops with salt and pepper. Grill over high heat, turning once, until nicely charred outside and medium-rare within, about 6 minutes. Transfer the lamb to a platter and let rest for 5 minutes. Garnish with the mint leaves and pimentón, top with a drizzle of olive oil and serve immediately.
