Ingredients
- 2 tablespoons butter: Think rich and creamy! I recommend using high-quality, unsalted butter for a more balanced flavor.
- 1 small onion (finely chopped): A sweet onion adds a hint of sweetness; you can swap it with shallots if you want.
- 2 cloves garlic (minced): Fresh garlic is a must for that aromatic infusion!
- 1 and a half pounds fresh mushrooms (sliced): You can use button, cremini, or a mix! Just ensure they are fresh and firm.
- 4 cups chicken broth (or vegetable broth for a vegetarian option): Homemade broth is the best, but store-bought works too.
- 1 and a half teaspoons dried thyme: This adds an earthy aroma, but feel free to use fresh thyme—just use about three times the amount.
- 1 teaspoon Worcestershire sauce: This adds depth; for a vegetarian twist, use soy sauce.
- 1 teaspoon salt: Use fine sea salt for a smoother blend.
- 1/2 teaspoon black pepper: Freshly ground brings the best flavor.
- 4 tablespoons all-purpose flour: This helps thicken the soup. You can use a gluten-free blend as a substitute!
- 1 cup heavy cream: The star ingredient for creaminess! Coconut cream can be used for a dairy-free option.
Prep Notes: Make sure your butter is at room temperature for easier melting. Fresh herbs like thyme and quality broth will make all the difference!

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, allowing the mushrooms to release their moisture and begin to brown slightly. You’ll know they’re ready when they start to brown and smell deliciously earthy!
Combine Ingredients: Pour in the chicken broth (or vegetable broth if making vegetarian), dried thyme, Worcestershire sauce, salt, and pepper. Stir well to combine all the ingredients.
Pressure Cook: Close the Instant Pot lid, making sure the valve is set to the sealing position. Cook on high pressure for 5 minutes. Once the cooking time is up, let the Instant Pot naturally release pressure for 10 minutes, then carefully do a quick release to release any remaining pressure.
Thicken the Soup: While the soup is still hot, whisk the flour into the heavy cream until smooth. Slowly pour this mixture into the soup, stirring constantly to prevent lumps. Turn on the sauté function again and allow the soup to simmer for 2-3 minutes until it thickens to your desired consistency.
Taste and Adjust: Taste the soup and adjust the seasoning if needed, adding more salt or pepper to suit your taste.
Storage: Store any leftover soup in an airtight container in the refrigerator for up to 4 days. For freezing, let it cool completely before transferring it to a freezer-safe container. It will keep in the freezer for up to 3 months. Thaw in the refrigerator overnight before reheating. Reheat gently over low heat on the stovetop or in the microwave.
Expert Tips & Tricks
Quality Matters: Use the freshest mushrooms you can find for the best flavor. Avoid pre-sliced mushrooms if you can—they tend to have a shorter shelf life and less flavor!
Control the Creaminess: If you want a lighter soup, reduce the amount of heavy cream or swap half of it with some low-fat milk. You can also add a splash of white wine for a little zing.
Store Properly: If freezing, leave some space in the container as the soup will expand. It’s best reheated slowly over low heat—this will keep its consistency and flavor.
Make Ahead: This soup actually tastes even better the next day! Prepare it in advance to let the flavors mingle.
Common Mistakes: Avoid overcooking the mushrooms in Step 2. They should just soften and brown slightly; if they’re overcooked, you won’t get that glorious texture.
Troubleshooting: If your soup is too thick after cooking, simply thin it out with a bit more broth or cream until you reach your desired consistency.
Serving Suggestions
This Instant Pot Creamy Mushroom Soup pairs beautifully with crusty artisan bread or a light, crisp salad. If you’re feeling fancy, top each bowl with crispy bacon bits or sautéed mushrooms for an extra dash of flavor.
