BRAISED MONKFISH WITH WILD MUSHROOMS AND CIPOLLINI ONIONS

Steps:

• Wrap bay leaf, rosemary, 2 sprigs thyme, peppercorns, and fennel seeds in a piece of cheesecloth and tie to form a bouquet garni; set aside. In a large saucepan, heat 1 tablespoon oil over medium-high heat. Add onion, fennel, celery, and garlic; saute until tender, 6 to 8 minutes. Pour over wine and stock, add bouquet garni, and bring to a boil. Immediately reduce heat to a simmer and cook until the liquid thickens to a sauce consistency, 45 to 60 minutes. Strain through a fine sieve, reserving liquid.
• Place cipollini onions in a roasting pan over medium heat. Drizzle with 1/2 cup oil, and season with salt and pepper. Toss to combine. Cook for 5 minutes, add mushrooms, and cook until vegetables are tender; set aside.
• Preheat oven to 375 degrees. In a large skillet, heat remaining 2 tablespoons oil over high heat. Pat fish dry with paper towels and season both sides with salt and pepper. Place in skillet and cook until browned on both sides.
• Add reserved liquid to a Dutch oven. Whisk in butter, tarragon, remaining 2 sprigs thyme, and vinegar. Add mushroom mixture and fish. Cover, and transfer to oven. Cook until just heated through, 10 to 12 minutes.
• Transfer fish to shallow bowls. Spoon sauce over fish, and serve.
