Use Quality Ingredients

The best mushroom bisque begins with fresh, quality ingredients. Mushrooms should be plump, clean, and firm. Organic items should be used when possible. Using the best possible ingredients will ensure the most rich flavor.

Mushrooms

You can use any type of edible mushrooms; however, the best mushroom bisque is created by using a combination of several varieties. This adds layers of flavor and creates dimension in the finished soup.

Some mushrooms to consider for these recipes are:

  • Shitake
  • Cremini
  • Chanterelles
  • Portabella
  • Button
  • Morels

Liquids

Chicken stock is another important ingredient in bisque. It is important to get a good quality stock that is salt-free. This allows you to adjust the seasonings to your taste. Organic and free range stock is first choice because of the superior flavor. You can also use homemade chicken stock.

Heavy cream contributes to the smooth, velvety consistency of the bisque. Don't be tempted to save grams of fat by using anything else. The result will not be as flavorful as when you use cream. There are differences in creams as well. Be sure to use heavy cream, rather than whipping cream. Heavy cream lists only cream and perhaps a stabilizer as ingredients. Whipping cream may be made from skim milk, stabilizers, oils, and other ingredients you don't want.

Garnishes

Garnishes finish the soup and give it a professional presentation. You can garnish mushroom bisque with many ingredients. Consider some of the following:

  • Sprinkle chopped green onions or chopped chives on top.
  • Float a large crouton sprinkled with grated Parmesan cheese in the soup.
  • Sprinkle the soup with crumbled, cooked bacon or pancetta.
  • Drizzle a little extra-virgin olive oil over the top.
  • Sprinkle with shaved Parmesan cheese.
  • Garnish with fresh basil leaves.
  • Saute some sliced mushrooms and sprinkle them on top.

An Elegant Soup
