Ingredients for vegan potato soup recipe instant pot
Roasted potatoes, aromatic herbs, and plant-based richness create this velvety vegan soup masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 lb | Cut into 1-inch cubes, roasted first |
| Yellow Onion 🧅 | 1 whole | Sliced into half-moons, caramelized |
| Garlic Cloves 🧄 | 4 cloves | Roasted with potatoes for depth |
| Fresh Thyme 🌿 | ¼ cup | Stems removed, chopped finely |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, or 1 tsp dried |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred, homemade best |
| Unsweetened Almond Milk 🥛 | 1 cup | Full-fat for creaminess (or cashew milk) |
| Nutritional Yeast 🧀 | ¼ cup | For cheesy umami flavor |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For roasting potatoes |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, brightens flavors |
| Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Maple Syrup 🍯 | 1 tbsp | For subtle sweetness |

The Yukon Gold potatoes are the star here—roasting them first builds natural sweetness and creates that signature creamy texture when blended. Look for organic potatoes at Whole Foods or your local farmers market for the best flavor. The garlic and thyme should be fresh—Trader Joe's bulk section is perfect for small amounts. If you're short on time, dried thyme works at one-third the amount, but fresh is ideal. The vegetable broth is non-negotiable—homemade or high-quality low-sodium store-bought makes all the difference in flavor.
No almond milk? Cashew milk or coconut milk works just as well for creaminess. Fresh herbs wilt fast, so store them in damp paper towels in the fridge. The nutritional yeast might be new to you—Bob's Red Mill brand is widely available and adds that perfect cheesy depth. Want extra richness? Add a splash of silken tofu blended in (about 0.5 cup). For a smokier flavor, swap smoked paprika for a pinch of liquid smoke (start with 0.25 tsp).
This soup tastes even better the next day as flavors meld. Store in an airtight container for 4-5 days in the fridge. For freezing, portion into containers and it keeps for 3 months. The roasted potatoes can be prepped ahead—store them in the fridge for 2 days before cooking. Double the batch and freeze half for lazy weeknights. Serve with crusty bread or a sprinkle of vegan parmesan for extra indulgence.
Why You'll Love This Recipe
- 20-Minute Hands-Off: I swear by this Instant Pot shortcut—just toss in diced Yukon Golds, onions, and garlic, then walk away. No peeling, no boiling, no waiting for the stove to heat up. The high-pressure cooker does all the work while I sip tea and pretend I’m fancy.
- Herb Magic: That fresh rosemary and thyme? They turn this soup from good to ridiculously good. The rosemary adds this bright, piney note that cuts through the creaminess, while the thyme? It’s like a warm hug in a bowl. (And yes, the dried stuff works, but fresh makes it sing.)
- Leftover Goldmine: This soup actually tastes better the next day—thicker, richer, and perfect for lunch. I make a big batch on Sundays, and by Wednesday, it’s still my go-to. Freeze half if you’re feeling extra, or just reheat with a splash of plant milk for that velvety texture again.
- Budget-Friendly Luxury: Yukon Golds are a splurge, but they’re worth it—they stay creamy instead of turning to glue. Onions and garlic are cheap, and a few sprigs of herbs stretch far. Honestly, this soup costs me less than takeout but feels like I’m treating myself. (Between us, it’s my secret for pretending I have money.)
Step-by-step instructions for creamy vegan potato soup in the Instant Pot
This method delivers velvety texture and deep flavor without dairy, all in under 30 minutes.
Roast Potatoes and Aromatics for Maximum Flavor
Preheat your Instant Pot on the "Sauté" function using 2 tablespoons extra-virgin olive oil. Add the 2 lb Yukon Gold Potatoes cut into 1-inch cubes, 1 whole Yellow Onion sliced into half-moons, and 4 cloves Garlic Cloves (peeled). Stir gently to coat in the oil, then sprinkle with 0.5 teaspoon smoked paprika and 1.5 teaspoons sea salt. Roast for 8-10 minutes until the potatoes begin to soften and the onions caramelize slightly—you'll see them develop a golden hue and smell sweetly aromatic.
Here's the thing—roasting before cooking builds depth you won't get from raw ingredients. The potatoes will break down more easily later, and the onions will contribute natural sweetness. If your Instant Pot doesn't have a "Sauté" function, use a separate skillet first, then transfer everything to the pot.
Build the Base with Broth and Herbs
Pour in the 4 cups vegetable broth and scrape up any browned bits from the bottom of the pot—these contain concentrated flavor. Add the 0.25 cup fresh thyme (stems removed) and 0.25 cup fresh rosemary (chopped), then stir everything together. Secure the lid and set the valve to "Sealing." Cook on High Pressure for 10 minutes—this ensures the potatoes become fork-tender while maintaining their shape.
Don't skip the herbs here. They'll infuse the broth with earthy, piney notes that elevate the soup beyond basic vegetable flavors. If you're using dried herbs, reduce to 1 teaspoon each—fresh is always better for this technique.
Blend to Silky Perfection
Once the cooking time completes, allow a 10-minute natural release of pressure, then carefully release any remaining pressure. Using an immersion blender, blend the soup until completely smooth—this is where the magic happens. You should end up with a creamy, velvety texture without any visible chunks. If you don't have an immersion blender, carefully transfer the soup to a countertop blender in batches, blending until silky.
This blending step creates the signature creaminess without dairy. The potatoes' natural starches combine with the broth to form a luxurious texture. If the soup seems too thick after blending, add 1 cup unsweetened almond milk now to reach your desired consistency.
Finish with Creamy and Bright Elements
Return the blended soup to the Instant Pot and stir in the 1 cup unsweetened almond milk, 0.25 cup nutritional yeast, 1 tablespoon maple syrup, and 1 tablespoon lemon juice. Add 0.5 teaspoon ground black pepper and adjust the seasoning with additional sea salt if needed. Stir well and let the soup sit for 5 minutes to allow all the flavors to meld together—you'll notice the nutritional yeast developing a cheesy, umami depth while the lemon brightens everything.
The nutritional yeast is key here—it's what gives this soup that rich, savory quality that mimics dairy. Taste as you go; sometimes you need just a pinch more salt or a splash more lemon to balance the sweetness. The maple syrup might seem unusual, but it rounds out the earthy flavors beautifully.
Serve Warm with Fresh Garnishes
Ladle the soup into bowls and garnish with additional fresh rosemary sprigs and a drizzle of extra-virgin olive oil. Serve immediately while hot—this soup tastes best fresh from the pot. For extra richness, top each serving with a sprinkle of nutritional yeast or a dollop of vegan sour cream if you're feeling indulgent.
Each spoonful should deliver that perfect balance of creamy texture, herbal depth, and bright acidity. The roasted potatoes add natural sweetness that contrasts beautifully with the smoky paprika and earthy herbs. This isn't just a vegan potato soup—it's a comforting, restaurant-quality bowl that rivals any dairy-based version.
Pro Tips For Making Vegan Potato Soup Recipe Instant Pot
- Sear the Onion First: I learned this the hard way—skipping the sauté makes the soup taste flat. Use 2 tablespoons of olive oil and cook the diced onion over medium-high heat until it turns golden brown, about 5-6 minutes. That caramelization builds flavor you won’t get just dumping everything in.
- Cut Potatoes Evenly: Yukon Golds cook unevenly if they’re not uniform. Aim for 1-inch chunks—no smaller, or they’ll turn to mush. I use a knife to eyeball it, but a mandoline makes this step faster if you’re making it often. Trust me, your soup will thank you.
- Don’t Overfill the Pot: The Instant Pot needs room to work. Fill it only halfway with potatoes, broth, and veggies—never more than two-thirds. I’ve seen people ignore this and end up with a watery, undercooked mess. Leave space, and the pressure will do its job.
- Add Herbs Late: Fresh thyme and rosemary lose their punch when simmered too long. Toss them in during the last 5 minutes of cooking or stir them in right before serving. This keeps their bright, herbal notes instead of letting them turn bitter. (Yes, even if you’re impatient like me.)
Serving suggestions for this dish
Crusty Bread Pairing
Serve this velvety soup with a warm, crusty loaf of sourdough or baguette for the ultimate dipping experience. I love using Whole Foods 365 brand sourdough—its dense crust and tangy crumb perfectly complement the soup's richness.
For extra indulgence, toast the bread with garlic-infused olive oil and sprinkle with flaky sea salt before serving. 🥖
Fresh Herb Garnishes
Brighten each bowl with fresh chives or parsley for a pop of color and freshness. I like to finely chop 2 tablespoons fresh chives and sprinkle them over the soup just before serving.
For a more aromatic touch, add thin rosemary sprigs or a few black peppercorns to each bowl. These garnishes not only enhance flavor but also make the presentation more inviting.
Vegan Cheese Toppings
Add a sprinkle of nutritional yeast or vegan parmesan for a cheesy, umami boost. I recommend Follow Your Heart brand vegan parmesan—its nutty, savory flavor pairs beautifully with the soup.
For a smoky twist, try smoked vegan cheese or a drizzle of cashew cream on top. These toppings elevate the dish to restaurant-quality without compromising its plant-based integrity.
Side Salad Contrast
A light arugula salad with lemon vinaigrette cuts through the soup's creaminess beautifully. Toss 4 cups baby arugula with 2 tablespoons olive oil, 1 tablespoon lemon juice, and a pinch of sea salt.
The peppery bite of arugula balances the soup's richness, making each bite more dynamic. Serve the salad on the side or as a bed for a heartier presentation.
Warm Spiced Nuts
For a crunchy contrast, toast ½ cup pecans or walnuts with 1 teaspoon maple syrup and a pinch of cinnamon until golden. Sprinkle them over the soup just before serving.
The warm, nutty flavor adds texture and depth, making every spoonful more satisfying. Store-bought spiced nuts from Trader Joe's work in a pinch, but homemade is always better. 🌰
Beverage Pairings
Complement your meal with a sparkling apple cider or a light white wine like Sauvignon Blanc. The crisp acidity of these drinks cleanses the palate between bites of rich soup.
For a non-alcoholic option, try hibiscus tea—its tart, floral notes pair wonderfully with the soup's herbal and smoky flavors. A cold beer like Belgian witbier also works beautifully, especially if you prefer a refreshing contrast. 🍷

Frequently asked questions
Can I make this vegan potato soup without an immersion blender?
Transfer the soup to a countertop blender in batches, blending until completely smooth. Just be careful—hot liquids can cause steam burns. For extra safety, let the soup cool slightly before blending, or hold the lid down firmly while blending. The texture will still be velvety, just like with an immersion blender.
How do I adjust the thickness of the soup?
If your soup is too thick after blending, stir in 1 cup unsweetened almond milk or vegetable broth until you reach your desired consistency. For a thicker texture, simmer the soup uncovered for 5-10 minutes to reduce the liquid. The key is to taste as you go—this soup should coat the back of a spoon but still be easy to ladle.
Can I use sweet potatoes instead of Yukon Gold?
Yes, but the flavor and texture will differ slightly. Sweet potatoes add natural sweetness and a deeper orange color, but they won't blend as smoothly as Yukon Golds. For best results, roast them first just like the recipe calls for, then blend thoroughly. If you prefer a sweeter soup, you can reduce the maple syrup to ½ tablespoon to balance the flavors.
What if I don't have nutritional yeast?
Don't worry! You can substitute with ½ cup cashew butter blended with ½ cup warm water for creaminess, or simply add 1 tablespoon white miso paste for umami depth. For a cheesy flavor without nutritional yeast, try 1 tablespoon vegan butter mixed with 1 teaspoon lemon juice—it won't be identical, but it'll still taste delicious.
Can I make this soup ahead of time?
Yes, this soup actually tastes better the next day as the flavors meld together! Store it in an airtight container in the fridge for 4-5 days or freeze for 3 months. Reheat on the "Sauté" function in your Instant Pot until hot, stirring occasionally to prevent sticking. For best texture, add a splash of plant-based milk or broth when reheating if it thickens.
