For the best herb crusted rack of lamb, marinate it overnight, cover in breadcrumbs, oven roast, and pair it with with a silky red wine sauce. This elegant recipe is perfect for the holidays or for a dinner party any time of the year.
Trim the lamb racks of visible fat and connective tissue. Put each rack into a resealable bag. Mix together all the marinade ingredients and pour half into each bag. Seal the bags, place them into a bowl or dish in case they leak, and put them into the refrigerator for at least 8 hours and up to 24 hours.
Preheat oven to 400F.
Mix together the bread crumbs, parsley, herbs, salt and pepper. Add enough olive oil to moisten the crumbs so they hold together, about 1 tablespoon.
Heat the remaining tablespoon of olive oil in a heavy large skillet over medium high heat. Take the lamb racks out of the marinade and wipe them down with paper towels. (If you wish, partially cut the rack through every two chops. This will make it easier to cut them into chops later.) One rack at a time, sear the racks in the skillet, about 2 minutes per side.
Transfer the racks to a roasting pan, meaty sides up. Coat the meaty side of each rack with mustard and then top each with half of the bread crumbs, patting it into place. Roast the racks for 20-25 minutes, until a thermometer reads about 130F for medium rare. Let the racks rest for 10 minutes, then serve with the wine sauce.
Pass the sauce through a fine mesh strainer and discard the solids.
Serve the lamb with the sauce along side.
