Roasted Rack of Lamb with White Bean Puree and Red Wine Reduction

1 . Stage

Heat olive oil for red wine reduction in a large saucepan over medium heat. Add onion and celery; saute until slightly brown, 8 to 10 minutes. Add Cabernet, tomatoes, apple, vinegar, butter, and garlic; simmer until sauce has reduced and is thick enough to coat the back of a spoon, 15 to 30 minutes. Strain and keep warm.

2 . Stage

At the same time, combine beans, butter, and garlic for bean puree in a small saucepan over medium heat. Cook for about 25 minutes, then puree with an immersion blender, adding white whine to thin if needed.

3 . Stage

Preheat the oven to 450 degrees F (230 degrees C).

4 . Stage

Combine bread crumbs, 2 tablespoons olive oil, garlic, rosemary, mustard, 1 teaspoon salt, and 1/4 teaspoon pepper in the bowl of a food processor; pulse gently until blended.

5 . Stage

Heat remaining 1 tablespoon oil in an oven-proof skillet over high heat. Season lamb with salt and pepper and sear racks on both sides until browned, about 3 minutes per side. Coat racks liberally with bread crumb mixture.

6 . Stage

Transfer to the preheated oven and cook until an instant-read thermometer inserted into the center reads at least 145 degrees F (68 degrees C), 12 to 15 minutes. Allow racks to rest before cutting into 2-rib servings.

7 . Stage

Place ribs in the center of serving plates. Drizzle reduction sauce on and around the ribs and spoon the bean puree into slight mounds on 3 sides outside the reduction.
