White Bean Ragoût with Lemon Oil and Shiitake Mushrooms Recipe

Directions:

1. Place beans in large pot. Add enough cold water to cover beans by 3 inches; let stand overnight. Drain.
2. Return beans to same pot. Add 8 cups water; onion and bay leaves. Bring to boil. Reduce heat; cover and simmer until beans are tender, stirring occasionally, about 1 hour. Reserve 1 cup cooking liquid. Drain beans; transfer to baking pan. Discard onion and bay leaves.
3. Meanwhile, combine oil and lemon slices in heavy medium saucepan. Simmer over low heat until lemon slices are translucent, about 5 minutes. Let cool uncovered 30 minutes. Strain lemon oil into bowl. Transfer 4 lemon slices to plate; cut in half and reserve (discard remaining lemon slices). (Beans, cooking liquid, lemon oil and lemons can be prepared 1 day ahead. Chill separately.)
4. Heat 4 tablespoons lemon oil in heavy large pot over medium-high heat. Add mushrooms and sauté until brown and tender, about 5 minutes. Add beans, 1 cup reserved cooking liquid, remaining lemon oil, herbs and lemon juice to mushrooms. Simmer over medium heat 5 minutes to blend flavors. Cool completely.
5. Stir chopped tomatoes and grated Parmesan cheese into bean mixture season to taste with salt and pepper. Spoon bean mixture onto platter. Garnish with halved lemon slices.
