- STEP 1
Preheat oven to 475F.
- STEP 2
Combine seasonings in a small bowl and sprinkle over the meat
- STEP 3
Heat a large heavy skillet over high heat and add 1 tablespoon olive oil. Brown lamb on both sides for 3 minutes each side. Pour off fat from pan, but save any juices to make pan sauce later.
- STEP 4
Transfer lamb to roasting pan and roast, fat side up, in the middle of the oven for 13-15 minutes until the internal temperature is 130-135F for medium-rare. Remove racks to a warm platter and let rest for 10 minutes while you make the sauce.
- STEP 5
Set the original skillet back on a burner. Add stock and scrape up any browned pieces from the bottom of the pan. Reduce to about 1 tablespoon. Add vinegar and remove pan from heat and whisk in the remaining 3 tablespoons olive oil and mint to form vinaigrette. Cut the racks into individual chops and serve, topped with the sauce atop salad greens.
