Author Notes: Meaty, smoky chestnuts and fresh aromatic herbs add depth to an otherwise ordinary, creamy mushroom soup. Use bottled, dried, or -- if you're up for the challenge -- freshly roasted chestnuts. For a richer soup, I suggest using cream; 2% milk is best if you're looking to save calories. - Food Blogga

Serves 4

3 tablespoons butter, divided
1 tablespoon olive oil
1/2 cup diced shallots
1 cup diced celery
2 1/2 cups peeled, diced red bliss potatoes (about 3)
8 cups mixed mushrooms, cremini and white button (about 2 1/2 pounds)
4 cups mushroom broth
8 ounces cooked chestnuts (about 20)
1/2 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
1 tablespoon fresh chopped rosemary
1 tablespoon fresh chopped sage
1/4 teaspoon sea salt
1/4 teaspoon freshly ground black pepper
1 1/2 cup cream
fresh sage, rosemary, and chopped chestnuts for optional garnish

Warm 2 tablespoons butter and olive oil in a large, deep pot over medium heat. Add shallots and celery, and sauté 3-5 minutes. Add potatoes and mushrooms, and cook for 8-10 minutes, or until mushrooms have released most of their liquid. Add broth, and bring to a boil. Reduce to low, and cook until potatoes are tender, about 10-12 minutes. Add chestnuts, cinnamon, nutmeg, rosemary, sage, salt, pepper, and cream. Turn off heat, and let cool for 10 minutes before pureeing.
Working in batches, puree the soup in a blender until smooth; return to the pot over low heat. Stir occasionally until the soup is thoroughly heated, about 10 minutes. Just prior to serving, stir in remaining 1 tablespoon butter for added creaminess and depth of flavor. Season to taste with salt and black pepper.
Garnish individual bowls with fresh herbs and chopped chestnuts, if desired.
