Why This Recipe Works

Mushroom wild rice soup is one of those meals that feels wholesome and a little luxurious at the same time (the mix of earthy cremini or shiitake mushrooms and nutty wild rice creates a layered, savory richness).
The pressure cooker helps soften the rice while locking in all the savory flavors (done in about 25 minutes at high pressure).

• No pre-cooking the rice - Wild rice cooks fully and evenly right in the pot.
• Mushrooms give it richness - Sautéed mushrooms build a deep, savory base.
• One-pot recipe - Sauté, pressure cook, and stir all in the same pot.
• Customizable - Add more veggies or make it dairy-free.
• Meal prep ready - Makes a solid batch and reheats beautifully.

It's a recipe that feels special, even if you're just making it for a regular Tuesday dinner; consider pairing it with blended cocktails for summer entertaining and honey-based chilled desserts for summer.

What You’ll Need

This soup keeps it simple but balanced.
You don't need fancy mushrooms or a long list of ingredients-just a few good basics like onion, carrots, celery, and good broth.

Save for Later!

• Wild Rice Blend - Use a real wild rice mix (not quick-cooking). It holds up well and adds texture.
• Mushrooms - Cremini, white, or a mix of whatever you have (cremini provide a meaty texture while shiitake add a deeper umami).
• Carrots, Celery, Onion - Classic aromatics for flavor and body.
• Garlic - Adds depth and a savory kick.
• Vegetable or Chicken Broth - Either works well; vegetable broth keeps it vegetarian.
• Thyme and Bay Leaf - Just enough herb flavor without overpowering.
• Heavy Cream or Coconut Milk - Swirled in at the end for creaminess; for a classic starter, see what deviled eggs are.
• Olive Oil or Butter - Used for sautéing and adding richness.

If you like it thicker, you can blend part of the soup or add a small cornstarch slurry after cooking.

How to Make It in the Instant Pot

This soup comes together in four easy steps, and you do everything in the same pot.

1. Sauté the vegetables and mushrooms - Set the Instant Pot to Sauté. Cook the onions, carrots, and celery in oil until softened. Add garlic and mushrooms, and cook until mushrooms release their liquid.
2. Add the rice and broth - Stir in the wild rice, broth, thyme, bay leaf, and some salt and pepper.
3. Pressure cook - Lock the lid and cook on high pressure for 35 minutes. Let it naturally release for 10 minutes.
4. Stir in cream and adjust - Open the lid, discard the bay leaf, and stir in the cream. Adjust seasoning to taste.

That's it. The wild rice is chewy and tender, and the broth is full of flavor from the mushrooms and herbs.

Add-Ins and Toppings That Work

You can build on the base with whatever's in your fridge-or just keep it classic; it also pairs well with easy no-boil pasta dinners.

Add-In or Topping	Why It Works
Spinach or Kale	Stir in at the end for a fresh touch
Parmesan	A salty finish if you’re not keeping it dairy-free
Croutons	Add crunch to the creamy base
Red pepper flakes	For a subtle heat
Lemon juice	Brightens the overall flavor
Fresh thyme	Sprinkle on top to reinforce the aroma

You could even throw in shredded rotisserie chicken if you want a protein boost (rotisserie chicken is already cooked and adds a savory, time-saving protein option). Shred it finely so it heats through quickly.

How to Store and Reheat

This soup makes great leftovers.
It thickens a bit in the fridge, but that's easy to fix with a splash of broth or water.

Storage Tips

• Cool completely before refrigerating.
• Store in sealed containers up to 4-5 days.
• Freeze in small batches for up to 2 months.

Reheating Tips

• Stovetop - Warm slowly over medium heat, adding broth as needed.
• Microwave - Heat in 60-second bursts, stirring between rounds.

Reheat gently so the cream doesn't separate, and you're good to go.

Common Questions About Mushroom Wild Rice Soup

Can I use only white rice?
It won't hold up the same way. Wild rice is firmer and made for soups like this.

Can I skip the cream?
Yes. You can use coconut milk, a dairy-free creamer, or just leave it brothy.

What's the best mushroom type?
Cremini or baby bella mushrooms have more flavor, but white mushrooms work fine too.

Can I use quick-cooking wild rice?
Not recommended. It can overcook and turn mushy under pressure.

Can I add meat?
Yes. Shredded chicken or browned sausage would work well here.

If you want a meatier version that keeps the same wild rice base, consider the Instant Pot recipe that pairs shredded chicken with wild rice in a single pot: shredded chicken with wild rice.
