What Are Instant Pot Creamy Mushroom Soups?

Instant Pot Creamy Mushroom Soup marries the earthy flavors of fresh mushrooms with a silky smooth texture, offering an indulgent dining experience all while being quick and easy to make. The origins of mushroom soup can be traced back to Europe, where wild mushrooms were foraged and transformed into a delightful dish. Its captivating umami flavor comes from the combination of fresh mushrooms—like cremini or shiitake stirred into a base of broth, cream, and herbs.

What truly sets this creamy masterpiece apart is the Instant Pot’s ability to infuse and meld the flavors quickly, transforming simple ingredients into a lush, comforting soup within minutes. Whether it’s a chilly evening or you simply need a soul-warming meal, this soup is the perfect choice—it’s rich, creamy, and oh-so-satisfying!

Ingredients Section

2 tablespoons butter: Use unsalted butter for better control over seasoning and to allow the natural flavors to shine. Do let it come to room temperature for easier melting.
1 small onion (finely chopped): Fresh onions provide a sweet base note to the soup.
2 cloves garlic (minced): Feel free to add more for a richer flavor.
1 and a half pounds fresh mushrooms (sliced): Cremini mushrooms work beautifully for this soup, but feel free to mix in shiitake or portobello for variety.
4 cups chicken broth (or vegetable broth for a vegetarian option): Look for low-sodium brands so you can control the saltiness.
1 and a half teaspoons dried thyme: This herb complements the mushrooms wonderfully; you can also use fresh thyme if you have it on hand!
1 teaspoon Worcestershire sauce: It adds a subtle depth of flavor that elevates the overall taste.
1 teaspoon salt: Adjust to taste, especially if using broth that is already salted.
Half teaspoon black pepper: Freshly cracked pepper gives the best flavor.
4 tablespoons all-purpose flour: This is essential for thickening the soup—consider using a gluten-free option if needed.
1 cup heavy cream: For that ultimate creamy finish! You can substitute with half-and-half for a lighter version.

Proper ingredient preparation translates to better flavor, so chop your vegetables beforehand and let your butter soften.

Step-by-Step Instructions

Sauté the Aromatics: Set your Instant Pot to the sauté function and melt the butter. Add the finely chopped onion and minced garlic, sautéing for about 2–3 minutes until they soften and become fragrant.
Cook the Mushrooms: Stir in the sliced mushrooms and cook for an additional 2–3 minutes. You want them to release their moisture and brown slightly, intensifying their flavor.
Add the Broth and Seasonings: Pour in the chicken or vegetable broth, dried thyme, Worcestershire sauce, salt, and black pepper. Stir to combine everything beautifully.
Pressure Cook: Close the lid and set the valve to sealing. Cook on high pressure for 5 minutes. Let the pressure release naturally for 10 minutes before performing a quick release for any remaining pressure.
Thicken the Soup: In a small bowl, whisk the flour into the heavy cream until smooth. Slowly pour this mixture into the soup while stirring to prevent lumps. Turn on the sauté function again and let it simmer for 2-3 minutes until thickened.
Final Touches: Taste the soup and adjust seasoning, if needed. The beauty of homemade soups is that you can tweak them to your liking!
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months.

Expert Tips & Tricks

Mushroom Variety: Mix and match assorted mushrooms for a unique flavor profile! Consider adding a handful of dried mushrooms for extra depth.
Broth Selection: Using homemade chicken or vegetable broth will elevate the soup’s taste. If you’re using store-bought, opt for a high-quality brand.
Make Ahead: You can prepare the base up to step 3 ahead of time. Store it in the fridge and finish the last few steps when you’re ready to enjoy your soup.
Storage: Cool the soup completely before storing. It keeps best in the fridge for 4 days or you can freeze portions for quick meals later.
Troubleshooting: If your soup turns out too thick, simply stir in more broth or water until you reach your desired consistency.
