2. Preheat the oven to 375 degrees F.
3. In a large cast-iron skillet over medium heat 1 tablespoon olive oil and 1 tablespoon butter. Once the pan is very hot, brown the racks of lamb on each side. Place in the preheated oven. Roast in the oven for about 10-15 minutes, then cover loosely with aluminum foil. Cook for about another 10 minutes, or until a meat thermometer registers 120 degrees F.
