This creamy vegan soup transforms simple ingredients into restaurant-quality comfort in your Instant Pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 1 whole | Diced small for even cooking |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic base |
| Russet Potatoes 🥔 | 2 lbs | Peeled, cubed evenly |
| Full-Fat Coconut Milk 🥥 | 13 ½ oz | Canned, unsweetened |
| Nutritional Yeast 🍞 | ½ cup | For cheesy flavor boost |
| Vegetable Broth 💧 | 3 cups | Low-sodium preferred |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped |
| Smoked Paprika 🌶️ | 1 tsp | For subtle smoky depth |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Vegan Butter 🧈 | 2 tbsp | For blending richness |

The potatoes are the heart of this soup—Russet potatoes have the perfect starchy texture, but Yukon Golds work too. Look for organic potatoes if possible, as they tend to be waxier and hold up better during blending. Trader Joe's carries great organic Russets, or check the bulk bins at Whole Foods. For the coconut milk, full-fat canned coconut milk (like Thai Kitchen brand) gives the best creaminess—none of that watery stuff. Nutritional yeast is a game-changer here; Bob's Red Mill
No fresh thyme? Dried thyme at one-third the amount works in a pinch, but fresh makes all the difference. Smoked paprika can be swapped for regular paprika, though you'll lose that subtle smokiness. For the broth, low-sodium vegetable broth is key—no one wants their soup tasting like a salt lick. The vegan butter adds richness during blending; Miyoko's or Earth Balance brands melt beautifully. And if you're short on parsley, fresh cilantro or basil can garnish just as nicely—just adjust the flavor profile. This soup tastes even better the next day as flavors meld. Store leftovers in airtight containers for up to 5 days or freeze for 3 months—perfect for meal prep. For reheating, add a splash of water or broth to restore creaminess. The Instant Pot's steam release valve should be used carefully; always follow manufacturer guidelines. Double batches freeze beautifully—just portion into containers before freezing for easy reheating.

Step-by-step instructions for creamy vegan potato soup in the Instant Pot
Here's how to transform simple ingredients into a luxurious, velvety soup that's rich, satisfying, and ready in record time.
Sauté the Aromatic Base
Set your Instant Pot to "Sauté" mode and add the 1 tablespoon olive oil. Once shimmering, add the diced yellow onions and cook for 3-4 minutes until they soften and become translucent. This foundational step builds flavor—don't rush it.
Add the 4 cloves minced garlic and cook for another 30 seconds until fragrant. Here's the thing—garlic burns fast, so keep the heat at medium and stir constantly. The moment it releases that nutty aroma, you're ready for the next step.
Build the Creamy Foundation
Pour in the 3 cups vegetable broth and scrape up any browned bits from the bottom of the pot with a wooden spoon. This technique, called deglazing, captures all the flavor you've built so far. Add the 2 lbs cubed russet potatoes, 1.5 teaspoons sea salt, 1 teaspoon smoked paprika, 0.5 teaspoon ground black pepper, and 1 tablespoon chopped fresh thyme. Stir gently to combine.
Here's where the magic happens: Add the 13.5 ounces full-fat coconut milk and 2 tablespoons vegan butter. The coconut milk will create that luscious texture we're after, while the butter adds richness. Give everything a good stir to distribute the coconut milk evenly throughout the broth.
Pressure Cook to Perfection
Secure the lid on your Instant Pot and set the valve to "Sealing." Cook on High Pressure for 8 minutes. This short cook time ensures the potatoes remain creamy rather than falling apart. Real talk: Russet potatoes break down quickly under pressure, so we're aiming for tender but still intact cubes.
When the cooking cycle completes, allow a natural release for 10 minutes before quick-releasing any remaining pressure. This gradual release prevents the soup from becoming watery as the potatoes absorb excess moisture. The result should be potatoes that are fork-tender with just a slight bite—this texture is ideal for creamy soups.
Blend to Velvety Smoothness
Carefully remove the lid and transfer half the soup to a blender. I use an immersion blender for convenience, but a countertop model works too. Blend until completely smooth, then pour the blended soup back into the Instant Pot. Add the 0.5 cup nutritional yeast and stir vigorously—this adds that unmistakable cheesy depth that makes this soup extraordinary.
Taste and adjust seasoning if needed. The nutritional yeast should enhance the savory notes, while the coconut milk provides natural creaminess without dairy. If you prefer an even smoother texture, blend the entire soup, though some prefer the slight potato texture for contrast.
Finish and Serve with Flair
Return the soup to "Sauté" mode and heat through for 2-3 minutes until warmed completely. This final step ensures all flavors meld together perfectly. Stir in the 0.25 cup chopped fresh parsley just before serving—it adds a bright, fresh finish that cuts through the richness.
Ladle the soup into bowls and garnish with additional parsley if desired. The perfect bowl of vegan potato soup should be velvety smooth with a luxurious mouthfeel, rich from the coconut milk and nutritional yeast, and perfectly seasoned. Serve with crusty bread to soak up every last drop—you'll want to savor every spoonful of this comforting creation.
Pro Tips For Making Vegan Potato Soup Recipe Instant Pot
- Sear the Onions: Don’t just soften them—crank the Instant Pot to sauté mode and cook the onions until they’re deep golden, almost caramelized. I used to skip this, and the soup always tasted flat; now it’s the richest base. (Yes, even if you’re impatient like me.)
- Cut Potatoes Evenly: Russets break apart when overcooked, so slice them into 1-inch chunks—no smaller, no larger. Uneven pieces mean some turn to mush while others stay raw. Trust me, your soup will be creamy and consistent.
- Stir After Pressure: As soon as the Instant Pot beeps, quick-release the pressure and give the soup a hard stir. The coconut milk separates when left undisturbed, and you’ll end up with a greasy layer on top. This is the thing that matters most.
- Swap Half the Milk: Replace ½ cup of coconut milk with light coconut milk or unsweetened almond milk—it cuts the richness without sacrificing creaminess. My grandmother swore by this, and she was right: the soup stays lighter but still velvety.
Make-ahead tips for this recipe
Prep Ahead Strategy
Double the recipe and store leftovers in airtight glass containers for up to 5 days in the fridge. The flavors actually deepen overnight, making it perfect for meal prep. I like using Pyrex glass jars because they stack neatly in the fridge and reheat evenly. 💫
Freezing for Later
This soup freezes beautifully for 3 months—just portion into quart-sized freezer bags before freezing. Leave 1 inch of headspace to prevent expansion cracks. Thaw overnight in the fridge before reheating.
For quick reheating, transfer frozen portions to the Instant Pot with ½ cup water or broth and cook on High Pressure for 3 minutes.
Pre-Chop Ingredients
Save time by prepping all ingredients the night before. Dice the yellow onions and cube the Russet potatoes ahead of time, storing them in separate airtight containers in the fridge. Minced garlic can be stored in a small jar with a splash of olive oil to prevent browning.
This way, you'll only need 10 minutes of active prep time when you're ready to cook. ✨
Make the Base First
For an even faster assembly, sauté the onions and garlic in advance and store them in the fridge. When you're ready to cook, simply add the pre-sautéed base to the Instant Pot with the remaining ingredients.
This shortcut cuts your active cooking time by half while maintaining all the flavor. Just add the coconut milk and vegan butter fresh for that velvety texture.
Batch Cook for Busy Weeks
Make two full batches at once and freeze one portion immediately. This ensures you always have a comforting meal ready, whether you're short on time or just craving something hearty. Label your freezer bags with the date and reheating instructions—trust me, you'll thank yourself on busy weeknights. 💪
Reheat Like a Pro
To restore creaminess after reheating, add 2-3 tablespoons of water or broth for every 2 cups of soup. Heat on Sauté mode for 3-4 minutes, stirring occasionally.
If using the microwave, cover with a damp paper towel and heat in 1-minute intervals, stirring between each to prevent uneven heating. The soup should reach 165°F for safe serving.

Frequently asked questions
Can I make this soup without coconut milk?
Yes! For a lighter version, replace the coconut milk with 1 cup unsweetened cashew cream (blend soaked cashews with water) or ½ cup silken tofu blended with ½ cup broth. The soup will be less rich but still creamy. For extra thickness, add 1 tablespoon cornstarch mixed with 2 tablespoons water after blending.
Why did my soup turn out watery?
This usually happens when potatoes overcook or release too much starch. For next time, reduce pressure cook time to 6-7 minutes and use Yukon Gold potatoes (they hold up better than Russets). Also, let the soup sit for 5 minutes after blending—starches will settle, allowing you to skim excess liquid off the top before serving.
How do I make this soup spicier?
Boost the heat by adding ½ teaspoon cayenne pepper or 1 teaspoon hot sauce (like Frank's RedHot) during the sauté step. For smoky depth, increase smoked paprika to 1.5 teaspoons. Garnish with red pepper flakes or a drizzle of sriracha before serving. Always taste as you go—build heat gradually!
Can I use frozen potatoes instead of fresh?
Fresh potatoes work best for texture, but you can use frozen—just thaw and pat dry first. For even cooking, cut frozen potatoes into ½-inch cubes (smaller than fresh) and add 1 extra minute to pressure cook time. The soup will still be creamy, though the texture may be slightly grainier. Never skip thawing frozen potatoes!
What's the best way to reheat leftovers?
For best results, transfer soup to the Instant Pot with ½ cup water or broth and reheat on Sauté mode for 3-4 minutes. If using microwave, heat in 1-minute intervals (stirring between) to prevent separation. Add a splash of coconut milk if the soup seems too thick after reheating—this restores creaminess instantly.
