Ingredients You’ll Need
Gathering simple, fresh ingredients is the key to unlocking the full flavor of this soup. Each item plays an essential role—from building a rich, savory base to creating that luscious creamy texture you’ll crave.
- Butter (2 tablespoons): Adds richness and helps develop a deep flavor by sautéing the veggies.
- Olive oil (1 tablespoon): Balances the butter’s flavor and prevents it from burning during sautéing.
- Medium onion, finely chopped (1): Brings sweetness and a subtle crunch after cooking.
- Garlic cloves, minced (3): Infuse the soup with aromatic warmth that pairs beautifully with mushrooms.
- Fresh mushrooms, sliced (16 ounces): The star ingredient, providing earthiness and meaty texture.
- Salt (1 teaspoon): Enhances all the natural flavors in the soup.
- Black pepper (1/2 teaspoon): Adds a gentle kick to balance the creaminess.
- Dried thyme (1 teaspoon): Offers an herby note that complements mushrooms perfectly.
- Vegetable broth (4 cups): Creates a savory, umami-rich base without overpowering the mushrooms.
- Heavy cream (1 cup): Gives luxurious creaminess and smooth mouthfeel, bringing everything together.
- All-purpose flour (2 tablespoons): Used to thicken the soup to the perfect consistency.
- Water (2 tablespoons): Helps make the flour slurry without lumps.
- Soy sauce (1 tablespoon): Adds depth and an extra layer of umami flavor.
How to Make Instant Pot Easy Mushroom Soup Recipe
Step 1: Sauté the Aromatics and Mushrooms
Set your Instant Pot to sauté mode, then melt the butter alongside the olive oil. Adding both fats not only gives you flavor complexity but ensures everything cooks evenly without burning. Toss in your finely chopped onion and cook until it softens, about 3 to 4 minutes—this mellow sweetness forms the bedrock of your soup’s flavor. Next, stir in the garlic and let it release its fragrant aroma for about 30 seconds. Then add the sliced mushrooms with salt, pepper, and thyme. Cook, stirring occasionally, until the mushrooms release their moisture and start to brown beautifully, which usually takes 5 to 7 minutes. This step is crucial—it builds a deep, rich flavor foundation that makes this soup stand out.
Step 2: Pressure Cook to Infuse Flavors
Pour in the vegetable broth and soy sauce, giving the mixture a good stir to scrape up any browned bits from the bottom—those are flavor gold. Secure the lid and set the valve to sealing. Cook the soup on high pressure for 5 minutes to let those earthy mushroom flavors intensify and meld with the herbs and broth. When time’s up, let it naturally release pressure for 10 minutes to keep the soup velvety, then carefully release any remaining pressure manually.
Step 3: Thicken and Creamify
In a small bowl, whisk together the flour and water to create a smooth slurry—this prevents clumpy thickening in the soup. Switch the Instant Pot back to sauté mode and slowly stir the slurry into the hot soup. Let it simmer a few minutes until it thickens slightly and coats the back of your spoon. Finally, stir in the heavy cream, warming it through for 2 to 3 minutes. At this point, taste and adjust seasoning if needed, because every batch can be a little different depending on the mushrooms you use.
How to Serve Instant Pot Easy Mushroom Soup Recipe
Garnishes
A sprinkle of freshly chopped parsley adds a pop of color and freshness, brightening the deep, rich flavors. Consider a swirl of extra cream or a dash of black pepper right before serving to elevate both the look and taste. For a bit of crunch, crispy fried shallots or garlic chips make a fabulous topping that contrasts perfectly with the creamy texture.
Side Dishes
This soup pairs beautifully with crusty bread or warm, buttery croissants that are perfect for dipping into every last spoonful. If you want to keep things light, a crisp green salad with a lemon vinaigrette complements the richness without overpowering it. For something heartier, grilled cheese sandwiches or roasted vegetable quiches add a cozy vibe to your meal.
Creative Ways to Present
Want to make dinner feel extra special? Serve the soup in rustic bread bowls, letting the soup soak into the bread as you eat. Another lovely idea is layering pureed soup with mushroom slices and herbs in clear glasses for a fancy appetizer look that will wow guests. Don’t forget, offering a side of truffle oil drizzle on top can turn this everyday soup into a gourmet treat.
Make Ahead and Storage
Storing Leftovers
This soup keeps beautifully in the fridge for up to 3 days in an airtight container. The flavors actually deepen after a day, making leftovers just as delightful as fresh. For best texture, stir the soup well before reheating as it may separate slightly when chilled.
Freezing
You can freeze this soup for up to 2 months with ease. Just let it cool completely, then transfer to a freezer-safe container or bag. When ready to enjoy, thaw overnight in the fridge, as freezing may alter the texture of the cream slightly, but a good stir and gentle reheating restore its deliciousness.
Reheating
The best way to reheat is gently on the stovetop over medium-low heat, stirring occasionally so it warms evenly and doesn’t scorch. If it thickens too much, thin it out with a splash of broth or milk. Microwave works too, just heat in short intervals, stirring between, to keep it creamy and smooth.
FAQs
Can I use different types of mushrooms for this soup?
Absolutely! While white button mushrooms work well, using cremini, shiitake, or a mix adds unique flavors and textures. Just slice them uniformly to ensure even cooking.
Is it possible to make this soup vegan?
Yes! Swap the butter for vegan margarine or olive oil and use coconut cream or a plant-based cream substitute instead of heavy cream. Make sure your vegetable broth is vegan-friendly as well.
Can I skip the soy sauce in the recipe?
You can, but the soy sauce adds a welcome depth and umami kick to the soup. If avoiding soy, consider using tamari or a splash of Worcestershire sauce for similar richness.
How can I make this soup thicker or thinner?
To thicken, add a bit more flour slurry or let the soup simmer uncovered longer. For a thinner soup, simply stir in extra broth until you reach your desired consistency.
Can I blend the soup for a smoother texture?
Definitely! You can blend part or all of the soup to create a creamy, velvety texture. Leaving some mushroom pieces whole adds a nice contrast if you prefer some chunkiness.
