Sprinkle lamb chops evenly with salt and pepper.
Brown chops in hot oil in a heavy skillet over medium-high heat 2 minutes on each side; place chops in a 13- x 9-inch baking dish, reserving drippings in skillet.
Bake at 400° for 15 minutes or until a meat thermometer inserted into thickest portion registers 150° (medium-rare). Let lamb chops stand 5 minutes before serving.
Sauté garlic in reserved drippings over medium heat 3 minutes or until lightly browned.
Stir together cream and next 3 ingredients in a small bowl. Add mixture to skillet, and bring to a boil over medium heat, stirring occasionally. Reduce heat, and simmer 5 minutes. Serve sauce with chops.
