Today is National Homemade Soup Day and it seemed appropriate to post the recipe for our wildly popular Wild Mushroom Chowder. Why this recipe didn’t make it into the cookbook is beyond me but I am happy to share it. We use a mix of cremini, shiitake and oyster mushrooms at the Tavern but a rich soup can be made using just creminis. I actually make it in an iron skillet instead of a soup pot to make sure the vegetables and mushrooms get good and brown. That caramelization is essential to a deep flavor in the soup. You can get away with using just 1 tablespoon of oil if you keep the heat at medium and cover the pan after you add the mushrooms. Mushrooms are little sponges and happily slurp up any oil or liquid they can. If you cover the pan and let them steam for 5 minutes they will begin to release their own delicious juices and will stew in them until tender.
Makes 2 quarts, serving 8
1 Tablespoon canola oil
2 1/3 cups finely chopped onion
1 quart coarsely chopped cremini mushrooms, about 12 ounces
1 ½ cups coarsely chopped, peeled carrots, about 2
2 cups small dice, peeled Idaho potatoes
4 cloves garlic, peeled, smashed and minced
½ cup beer, ale or dry sherry
5 1/3 cups water
2 large bay leaves
1 ½ teaspoons kosher salt, divided
1 cup heavy cream
½ teaspoon freshly ground black pepper
1 tablespoon minced fresh thyme leaves
1 tablespoon grainy mustard
2 tablespoons Worcestershire sauce

In a 3 quart saucepan over medium heat add the canola oil and heat until hot. Add the onions and carrots and sauté until browned. Add the mushrooms, lower heat to low and cover pan. Steam the mushrooms for 5 minutes until they soften and begin to give up their juices. Uncover pan, raise heat to medium and sauté mushrooms until they are tender. Add the potatoes and garlic.
Add the beer and bring to a boil, stirring. Add the water, bay leaves and ¼ teaspoon of the salt. Bring soup to a boil, reduce heat to low and simmer soup until potatoes are tender, about 15 minutes.
Add the remaining 1¼ teaspoons salt, cream, pepper, thyme, mustard and Worcestershire. Return soup to the boil, reduce the heat and simmer until slightly thickened, about 15 minutes more. Discard the bay leaves. Using a blender wand puree soup slightly if desired.
Serve immediately or cool quickly in an ice bath and refrigerate, covered, up to 5 days.
Tip: Use a mix of mushrooms if desired. You will need about 12 ounces of raw mushrooms before they are trimmed.
