• 2 garlic cloves
• 2 tablespoons extra-virgin olive oil
• 1 celery stalk, finely chopped
• 1 medium carrot, finely chopped
• 1/2 cup finely chopped onion
• Salt
• Freshly ground black pepper
• 1 (3-pound) rabbit, cut into 10 pieces
• 2 1/2 cups low-sodium vegetable broth   
• 3 1/2 ounces fresh porcini mushrooms (see note below)
• 3 tablespoons unsalted butter
• 1 1/4 cups finely chopped flat-leaf parsley
• 1 1/2 pounds fresh pappardelle egg pasta
• Freshly grated Parmigiano-Reggiano cheese
   

Peel and finely chop 1 garlic clove. Heat oil in a large Dutch oven or other wide heavy pot over medium-high heat. Add celery, carrot, onion, chopped garlic and generous pinch salt and pepper. Reduce heat to medium and cook, stirring occasionally, until vegetables are softened, about 5 minutes. Add rabbit pieces and broth. Tuck pieces into broth to mostly cover and bring to a gentle simmer. Reduce heat to low, cover and cook, turning pieces occasionally, until meat is tender, about 1 hour.

Meanwhile, wipe mushrooms with paper towels to remove any dirt or grit. Keeping stems attached, trim any discoloration from stems.Cut mushrooms into 1/4-inch dice.

Gently smash and peel remaining garlic clove. In a medium skillet, heat garlic and 1 tablespoon butter over medium heat. When butter is melted and bubbling, add mushrooms; cook, stirring frequently, for 3 minutes. Stir in parsley and pinch salt. Remove from heat.

Remove rabbit from heat. Transfer rabbit pieces to a plate, reserving sauce in pan. When cool enough to handle, pull meat from bones, taking care to remove and discard any small shards of bone. Chop meat into small pieces and return to sauce. Add mushroom mixture to sauce, bring to a gentle simmer and cook for 30 minutes; remove from heat and adjust seasoning.

Bring a large pot of salted water to boil. Just before adding pasta to water, gently reheat sauce; add remaining 2 tablespoons butter to sauce and stir to combine. Add pasta to water and cook until just tender, about 2 1/2 minutes (fresh pasta cooks much faster than dried). Drain pasta and transfer to a large serving bowl; add ragù and toss well to combine. Serve immediately, sprinkled with cheese.

Note: If fresh porcini mushrooms are not in season, use flash-frozen porcini. Fresh (in season) and flash-frozen porcini are available by mail order from Urbani Truffles and Caviar, 877-482-7883; urbanitartufi.com.
