Make the Marinade: Crush the garlic then use spoon to mix together with onion powder, rosemary, thyme, oregano, crushed red pepper, and olive oil in mixing bowl.
6 cloves garlic, 1 teaspoon onion powder, ½ teaspoon dried rosemary, ½ teaspoon dried thyme, ½ teaspoon dried oregano, ½ teaspoon crushed red pepper, 3 tablespoons olive oil
Marinate the Meat: Sprinkle salt and pepper over the lamb rack then rub into all sides of the meat. Then coat the lamb rack in the marinade and let sit at room temperature for one hour (or up to overnight in the refrigerator for even more flavor).
1 French-cut rack of lamb, sea salt, black pepper
Make the Chimichurri: Add mint leaves, parsley, olive oil, vinegar, sea salt, and maple syrup to food processor or blender and pulse until the herbs are chopped and mixture is broken down but chunky. Don’t overdo it or else you’ll end up with a puree--it shouldn’t be smooth. Taste test and adjust seasonings to your preference.
1 cup fresh mint leaves, ½ cup fresh parsley, 2 tablespoons white wine vinegar, ½ teaspoon sea salt, ¼ cup olive oil, 1 teaspoon maple syrup
Adjust oven racks so that the top oven rack is in the second-highest position. Preheat oven to 450 degrees Fahrenheit.
Prep the Lamb: Wrap the exposed bones of the lamb in aluminum foil so that they don’t char in the oven. Transfer marinated lamb rack, fatty side up, to oven-safe dish then place dish to top oven rack.
Roast the lamb: Allow lamb to cook for 15 minutes then use kitchen tongs to flip and roast another 5 to 15 minutes until it reaches your desired level of doneness (see recipe notes). Measure temperature by placing food thermometer into the thickest part of the meat, not near the bone.
Rest the Lamb: Tent lamb with foil and let rest for about 10 minutes before slicing and serving with chimichurri.
