Instant Pot Cajun Cream of Mushroom Soup

One of my most lauded soups is my Cream of Mushroom, which some has said is as legit as a gourmet restaurant’s. As I batted my eyes and blushed, I decided to give this soup the spicy Southern treatment by making it Cajun-style incorporating smokes sausage (andouille is my choice) and a Cajun/Creole/Louisiana seasoning. Adding some diced tomatoes will give this soup a Creole touch as tomato is a big differentiator between Cajun and Creole cooking. Whichever style you choose, this Cajun Cream of Mushroom Soup is a huge, zesty winner for mushroom and smoked sausage lovers alike!

Total Time 30 minutes

Ingredients

Optional Toppings

  • Shredded cheddar cheese
  • Fried onions

Instructions

  1. On the Instant Pot, hit Sauté and Adjust to the More or High setting. After 3 minutes of heating, add the sausage and sauté for 3-5 minutes until heated and browned. Remove the sausage to a bowl and set aside.
  2. The bottom of the pot will be caked on with some browned bits from the sausage. Add the Worcestershire sauce and deglaze/scrape the bottom so a good amount of the browned bits come up. Then, add the butter and sherry and continue to deglaze the bottom until the butter melts and to continue to deglaze until the bottom of the pot is nice and smooth.
  3. Add the mushrooms and sauté for 8-10 minutes until they begin to brown, sweat, reduce, and release a lot of their juices. As they do, continue to deglaze the bottom of the pot so it's smooth. Using a slotted spoon, remove 1 1/2 cups of the mushrooms and set aside.
  4. Add the onion and sauté for 3 minutes longer, just until slightly translucent. Add the flour and stir until absorbed by the juicy mushrooms and onions.
  5. Add the broth, garlic and thyme and stir until well-combined. Secure the lid, move the valve to the sealing position, and hit Cancel followed by Pressure Cook or Manual for 5 minutes on High Pressure. Quick release when done.
  6. Using an immersion blender, purée the soup until smooth. Add the cream, Cajun/Creole/Louisiana seasoning, and Ro-tel or diced tomatoes (if using, to give it a Creole touch). Return the reserved mushrooms and sausage. Stir to combine and serve topped with the optional cheddar and fried onions, if desired.

Jeffrey's Tips

Want this soup vegetarian? Use a plant-based sausage in place of the andouille. OR, simply leave it out completely and begin with Step 2 and add the butter, Worcestershire sauce, and sherry all at once when starting the recipe.

I cannot stress enough the importance and convenience of an immersion blender. It totally saves on the hassle and heated mess of transferring the soup, in batches, to a blender. Every homemade soup lover should own one.
