Roasted Lamb Chops with Charmoula and Skillet Asparagus

For charmoula:

Heat small skillet over medium heat. Add cumin seeds and toast until aromatic and slightly darker, stirring occasionally, about 2 minutes. Transfer to processor. Add parsley leaves and next 6 ingredients to processor. Using on/off turns, process until coarse paste forms. With machine running, gradually add 4 tablespoons oil. Transfer 2 tablespoons charmoula to small bowl; whisk in lemon juice and remaining 2 tablespoons oil. Cover and chill to serve with lamb.

For lamb:

Transfer remaining charmoula to large resealable plastic bag. Add lamb chops; seal bag and turn to coat well. Chill at least 4 hours and up to 24 hours.

Let lamb and charmoula sauce in bowl stand at room temperature 1 hour.

Preheat oven to 500°F. Line rimmed baking sheet with foil. Place rack on prepared baking sheet. Place lamb on rack and sprinkle with salt and pepper. Roast until thermometer inserted into center registers 130°F for medium-rare, about 13 minutes. Transfer lamb to platter. Tent with foil and let rest 5 minutes.

Meanwhile, melt butter with 1 tablespoon oil in heavy large skillet over high heat. Add asparagus and sauté until tender, stirring often, about 3 minutes. Add shallot and lemon peel. Sauté 1 minute. Season to taste with salt and pepper.

Place 2 lamb chops on each of 4 plates. Divide asparagus among plates. Drizzle lamb and asparagus with charmoula sauce, passing remaining sauce alongside.
