Ingredients You’ll Need

This recipe is delightfully simple with ingredients that pack incredible flavor and texture. When you shop, picking firm, unblemished potatoes will make all the difference in the creaminess and sweetness of your soup.

Russet potatoes: Their high starch content makes the soup wonderfully creamy after blending.
Sweet potatoes: Add natural sweetness and a silky texture that balances russets beautifully.
Chopped onion: Adds subtle savory depth without overpowering the potatoes.
Baby carrots: Offer a gentle sweetness and color; you can substitute regular carrots if needed.
Garlic cloves: For that fragrant aroma and mellow sharpness that rounds out the soup’s profile.
Vegetable stock: Provides the liquid base and savory notes; low-sodium stocks allow better control over salt.

Variations

I’ve found this Creamy Double Potato Soup Recipe to be such a great base that’s easy to tweak depending on what you have or your mood. Feel free to get creative!

Make it extra creamy: Stir in a splash of coconut milk or unsweetened plant milk at the end if you want a richer texture.
Add herbs: I sometimes throw in fresh thyme or rosemary for an herby twist that lifts the flavor.
Spice it up: Increase the cayenne or add smoked paprika for a smoky warmth that’s just addictive.
Boost protein: Top with crispy chickpeas or shredded vegan cheese for a heartier meal.

How to Make Creamy Double Potato Soup Recipe

Step 1: Prep Your Potatoes and Veggies

Start by peeling your russet and sweet potatoes — I roughly chop them so they cook evenly but not too tiny (no one wants mushy mess!). Chop the onion and mince the garlic cloves. This rough prep makes the slow cooker process totally hands-off, which I absolutely appreciate on busy days.

Step 2: Slow Cook for Tenderness

Add all your chopped potatoes, onions, garlic, baby carrots, and vegetable stock to the crockpot. Set it to low and let it cook for about 8 hours. When I first tried this, I was surprised how the flavors completely melded and how tender everything became without any stirring at all!

Step 3: Blend to Silky Perfection

Once your veggies are meltingly soft, stir in the nutritional yeast and cayenne pepper. Then, using an immersion blender right in the crockpot, blend everything until your soup reaches that dreamy, silky texture we all crave. Taste it and adjust salt and pepper carefully — vegetable stock sodium varies, so salt later to avoid overseasoning.

Pro Tips for Making Creamy Double Potato Soup Recipe

Choose the Right Potatoes: I always pick firm russets and sweet potatoes without spots to ensure smooth blending and consistent flavor.
Use an Immersion Blender: It’s a game-changer for blending soup straight in the pot — no transferring or extra cleanup!
Season Last: Because stocks vary in saltiness, waiting until the end to add salt helps avoid over-seasoning your soup.
Don’t Skip the Nutritional Yeast: It adds a subtle depth and “cheesy” richness that keeps this soup cozy without dairy.

How to Serve Creamy Double Potato Soup Recipe

A white bowl holds bright orange soup with swirls of white cream and a light sprinkle of black pepper on top; a wooden spoon resting inside the bowl lightly stirs the smooth, thick soup. Nearby, a white shallow bowl contains the same soup, decorated with a swirl of cream, green cilantro leaves, and dark green pumpkin seeds on its surface. To one side, there is a white small dish full of pumpkin seeds and a small wooden plate with fresh green microgreens. Three thick slices of crusty bread with a golden-brown crust and airy texture lie next to a white and blue checkered cloth on a white marbled surface. Two spoons, one silver and one with a dark handle, rest above the bowls. The colors are warm and inviting, set against a clean and bright background. photo taken with an iphone --ar 4:5 --v 7

Garnishes

I typically top this soup with a sprinkle of freshly chopped parsley or chives for a pop of color and freshness. Sometimes, I add a drizzle of good-quality olive oil or a dollop of plain vegan yogurt to amp up creaminess and visual appeal. A few roasted pumpkin seeds or crushed nuts add a nice crunch that balances the silky soup.

Side Dishes

My go-to sides with this soup are a slice of crusty whole grain bread or a simple green salad dressed with lemon vinaigrette. The bread is perfect for dipping, and the salad adds a fresh, crisp contrast that rounds out the meal beautifully.

Creative Ways to Present

For special occasions, I like to serve this Creamy Double Potato Soup Recipe in mini pumpkin bowls or hollowed-out sourdough bread bowls — it makes the meal feel so cozy and festive. You can also swirl in a little pesto or hot sauce on top before serving for visual interest and added layers of flavor.

Make Ahead and Storage

Storing Leftovers

I keep leftovers in an airtight container in the fridge for up to 4 days. The soup actually tastes even better the next day as the flavors continue to develop. Just give it a good stir before reheating.

Freezing

This soup freezes wonderfully. I portion it into freezer-safe containers with some headspace to allow for expansion. When you’re ready, thaw overnight in the fridge and reheat gently for delicious leftovers.

Reheating

To reheat, I warm the soup slowly over low heat, stirring occasionally. This keeps the texture silky and prevents it from sticking or burning. If it thickens too much, just stir in a splash of water or vegetable stock to loosen it back up.

FAQs

Can I make this soup without a slow cooker?

Absolutely! You can simmer all the ingredients on the stovetop over low heat for about an hour until the potatoes and carrots are tender. Just keep an eye on the liquid level and add stock as needed. Then blend as usual.
Is nutritional yeast necessary for the Creamy Double Potato Soup Recipe?

While it’s optional, nutritional yeast adds a lovely depth and subtle cheesy flavor that enhances the soup’s richness without dairy. If you don’t have it, you can skip it or substitute with a little vegan cheese or miso paste for umami.
How spicy is the soup with cayenne pepper?

Just a pinch of cayenne is used to add warmth without making it spicy-hot. You can adjust or omit depending on your preference or add other spices like smoked paprika for a milder flavor.
Can this recipe be made vegan and gluten-free?

Yes, it’s naturally vegan and gluten-free as long as you use certified gluten-free vegetable stock. It’s a fantastic comfort food option for many dietary needs!
