Ingredients
Here’s what you’ll need to create this luscious Instant Pot Creamy Mushroom Soup:
- 2 tablespoons butter (unsalted; room temperature for easy melting)
- 1 small onion (finely chopped)
- 2 cloves garlic (minced)
- 1 and a half pounds fresh mushrooms (sliced; I love using cremini or a mix of wild mushrooms for richer flavor)
- 4 cups chicken broth (or vegetable broth for a vegetarian option; homemade or low-sodium recommended)
- 1 and a half teaspoons dried thyme (fresh thyme works wonders too if you have it)
- 1 teaspoon Worcestershire sauce (adds depth; soy sauce can work as a substitute)
- 1 teaspoon salt (to taste)
- 1/2 teaspoon black pepper (freshly cracked is best for flavor)
- 4 tablespoons all-purpose flour (to thicken; use gluten-free flour for a gluten-free version)
- 1 cup heavy cream (for that velvety texture; coconut cream is a great dairy-free alternative)
Preparation Notes: Make sure your butter is at room temperature for easier melting, and have all your ingredients prepped and within reach to keep the cooking process smooth!

Step-by-Step Instructions
Sauté the Base: Set your Instant Pot to the sauté function and melt the butter. Add in 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.
Add the Broth and Herbs: 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, ensuring the valve is set to the sealing position. Cook on high pressure for 5 minutes. Once the cooking time is up, allow the Instant Pot to naturally release pressure for 10 minutes, then carefully perform a quick release for any remaining pressure.
Thicken the Soup: While the soup is still hot, whisk the flour into the heavy cream until it’s 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.
Season to Taste: Taste the soup and adjust the seasoning if needed, adding more salt or pepper to suit your taste.
Storage Options: Store any leftover soup in an airtight container in the refrigerator for up to 4 days. This soup freezes beautifully—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. If the soup thickens too much after refrigerating or freezing, simply add a splash of broth or water to thin it out.
Chef’s Tips:
- If you’d like a touch of brightness, try adding a squeeze of lemon juice before serving.
- For a more textured soup, reserve some sautéed mushrooms to stir back in at the end.
Common Mistake to Avoid: Adding the cream directly to the pot before thickening might cause lumps, so always whisk before adding!
Expert Tips & Tricks
Quality Ingredients Make a Difference: Using high-quality, fresh mushrooms will elevate the flavor dramatically. For an even richer taste, try mixing in some dried porcini mushrooms.
Make-Ahead Magic: You can prep the vegetables ahead of time, storing them in the fridge to save on time during busy weeknights.
Flavor Enhancements: Feel free to toss in some fresh herbs like parsley or dill right before serving for a vibrant finish.
Adjusting Thickness: If your soup doesn’t thicken as much as you’d like, whisk an extra tablespoon of flour into a bit of stock, then stir it in while simmering.
Storage Recommendations: This soup can be frozen in single-serve portions for easy meals later. Just remember to label your containers with the date!
Serving Suggestions
This Instant Pot Creamy Mushroom Soup is heavenly on its own, but here are some delightful accompaniments:
- Crusty Bread: A loaf of freshly baked sourdough or a baguette is perfect for dipping and soaking up the creamy goodness.
- Salad: Serve it alongside a light side salad for a complete meal—think arugula with cherry tomatoes and a balsamic vinaigrette!
- Presentation: Garnish with a drizzle of olive oil or a sprinkle of fresh herbs for a beautiful touch.
For a cozy dinner, this soup pairs beautifully with a grilled cheese sandwich, taking you right back to those comforting childhood memories.
Variations & Substitutions
Flavor Combinations: Try adding a splash of white wine for a more sophisticated flavor or a dash of sherry if you’re feeling adventurous.
Dietary Adaptations: For a dairy-free option, use coconut cream and vegetable broth. Those who prefer low-carb can use keto-friendly options like almond flour in place of all-purpose flour.
Seasonal Variations: Swap out mushrooms for seasonal favorites like butternut squash or pumpkin in the fall for a delightful twist. A hint of nutmeg can elevate that cozy autumn vibe.
