Mushroom Bisque
A good mushroom bisque should taste unmistakably of mushrooms. Cream can soften the edges and give the soup its smooth texture, but the deeper flavor comes from browning the mushrooms in butter, cooking the onions until tender, and letting the sherry and stock pull everything together.
This is the sort of soup I want once the weather turns cold enough for a heavy pot to stay on the stove. Mushrooms, thyme, garlic, chicken stock, dry sherry, and cream make a particularly good combination because each ingredient has a clear purpose. Thyme brings an herbal note that suits mushrooms naturally, chicken stock gives the soup body, and dry sherry adds a nutty, slightly sharp flavor that keeps the cream from making the soup feel too rich.
The word bisque comes from French cooking, where it became closely associated with smooth, richly flavored soups, especially those made with shellfish. In American cooking, the term eventually broadened and is now commonly used for smooth, cream-based soups made with ingredients such as tomatoes, squash, and mushrooms.
Mushrooms are especially well suited to this treatment because they develop much more flavor once their natural moisture has cooked away. A pound of sliced mushrooms may look generous when it first goes into the pot, but they quickly shrink as they release water. Giving them ten minutes or more to cook allows that liquid to evaporate and gives the mushrooms time to begin browning. That step creates much of the savory character of the finished soup.
The dry sherry is worth keeping. Mushrooms and sherry have long been paired in cream soups and sauces because the wine brings a slightly nutty flavor and enough acidity to sharpen the deeper flavors in the pot. Half a cup is enough to make its presence known without turning the soup into something wine-forward.
A small amount of flour gives the bisque structure before the stock is added. Once the soup has simmered for about twenty to twenty-five minutes, the mushrooms and onions are tender enough to blend into a smooth base. The heavy cream goes in at the end, where it rounds everything out without needing a long cooking time.
I like the finished bisque thick enough to lightly coat the spoon while still pouring easily into the bowl. Freshly ground black pepper and a few thyme leaves are all it needs at the table.
Serve it with toasted bread, a crisp green salad, or a simple sandwich for lunch. It also works well as a first course for a cold-weather dinner because the soup can be prepared ahead, refrigerated, and warmed gently before serving.
Until next time, thank you for spending a little time with me. I hope you find a recipe to make, a story to enjoy, and something new to take into the kitchen. ♥️
Mushroom Bisque
Prep Time: 15 minutes
Cook Time: 45 minutes
Servings: 4
Ingredients:
3 tablespoons unsalted butter
1 medium yellow onion, diced
1 pound fresh mushrooms, sliced
2 cloves garlic, minced
1 teaspoon kosher salt, plus more to taste
1½ tablespoons all-purpose flour
6 sprigs fresh thyme, tied together with kitchen twine, or ¾ teaspoon dried thyme
½ cup dry sherry
4 cups chicken stock
1 cup heavy cream
Freshly ground black pepper, to taste
Instructions:
- Melt the butter in a large pot or Dutch oven over medium heat.
- Add the diced onion and cook for about 5 minutes, stirring occasionally, until softened and translucent.
- Add the sliced mushrooms and cook for 10 to 12 minutes, stirring occasionally, until they have released their moisture, the liquid has mostly evaporated, and the mushrooms begin to brown.
- Add the garlic and cook for about 1 minute, just until fragrant.
- Stir in the kosher salt.
- Sprinkle the flour over the mushroom mixture and stir well. Cook for about 2 minutes, stirring continuously, to remove the raw flour taste.
- Add the thyme and pour in the dry sherry. Scrape the bottom of the pot with a wooden spoon to loosen any browned bits. Cook for 2 to 3 minutes, until the sherry has reduced slightly.
- Slowly pour in the chicken stock, stirring as you add it. Bring the soup to a gentle boil, then reduce the heat and simmer uncovered for 20 to 25 minutes.
- Remove the fresh thyme bundle, if using.
- Blend the soup with an immersion blender until smooth. If using a countertop blender, work carefully in batches and return the blended soup to the pot.
- Stir in the heavy cream and warm the bisque over low heat for 3 to 5 minutes. Do not allow it to boil.
- Taste and season with additional kosher salt and freshly ground black pepper as needed.
- Ladle into bowls and garnish with fresh thyme leaves or a few sautéed mushroom slices, if desired.
