There’s something magical about discovering a dish that’s as vibrant as it is nourishing. That’s exactly what happened one chilly autumn evening in Portland when I stumbled on a bag of purple potatoes at the farmers market. I’d seen them before, but always walked past. That night, though, their deep, jewel-like color practically begged me to bring them home. What started as curiosity turned into one of my most requested creations: purple potato soup. It’s hearty, earthy, and subtly sweet, with a color that turns heads and starts conversations.
In this article, we’re diving deep into what makes purple potato soup special—from its unique backstory and flavor profile to preparation tips, health comparisons, and recipe variations inspired by earthy ingredients like sweet potatoes and creative bars. Whether you’re already a fan of comforting bowls or just purple food, this one’s for you.
The Story and Simplicity Behind Purple Potato Soup
A humble origin with a striking result
The first time I made purple potato soup, I was experimenting. I simmered the vibrant tubers with sautéed garlic and shallots, adding just enough vegetable broth to blend it all into something smooth and satisfying. When I poured the mixture into the blender, it turned the most remarkable shade of lavender. Yes, purple potatoes do turn your soup purple—especially if you use varieties like Stokes or Okinawan sweet potatoes. They retain their color better than red cabbage or beets ever could, all thanks to anthocyanins.
It reminded me of that rich, layered warmth I get from carrot pasilla pepper soup, another winter favorite where the color tells part of the story before you even take a bite. The color may invite you in, but the comfort of the flavors keeps you coming back.
A plant-based classic with a twist
Purple potato soup offers something creamy and comforting—without the dairy. I use coconut milk or cashew cream, but you could go lighter with almond milk or even just blended potatoes alone. What makes it stand out, beyond the color, is how adaptable it is. You can season it with warming spices like cumin or smoked paprika, or keep it minimal with salt and cracked pepper.
This simplicity echoes the earthy appeal of something like papalo tea, where the ingredients don’t need much embellishment to shine. If you’re someone who appreciates letting vegetables speak for themselves, purple potato soup hits that perfect middle ground of rustic and refined.
Ingredients, Method, and What Makes This Soup Nutritionally Rich
Everything you need to make it
To create a rich and creamy purple potato soup, you only need a few plant-based essentials. This soup works well for weeknights and can be dressed up with toppings or sides for entertaining. Below is your go-to list:
| Ingredient | Amount |
|---|---|
| Purple potatoes (skin on, scrubbed) | 1.5 lbs |
| Leek or shallot (sliced thin) | 1 large |
| Garlic cloves (minced) | 3 |
| Vegetable broth | 4 cups |
| Coconut milk (full fat or lite) | 1 cup |
| Salt + pepper | To taste |
| Olive oil | 1 tbsp |
How to bring it all together
- Heat the olive oil in a large pot over medium heat. Add the sliced leeks and garlic, sautéing until soft and fragrant—about 4 minutes.
- Stir in the chopped purple potatoes and coat them gently with the aromatics.
- Add in the vegetable broth, bring to a boil, then reduce to a simmer. Cover and cook for 20–25 minutes until the potatoes are fork-tender.
- Remove from heat and allow the soup to cool slightly. Use an immersion blender or transfer in batches to a high-speed blender to puree until smooth.
- Stir in the coconut milk, then reheat gently. Season with salt and black pepper. For extra depth, try a hint of white pepper, just like in this Chinese white pepper soup.
- Serve warm with your favorite garnish: a swirl of coconut cream, roasted seeds, or herbs like cilantro or thyme.
Pair it with something cozy and earthy like green olive bread recipe to round out the meal with satisfying texture.
PFlavor Variations, Pairing Ideas, and Why This Soup Works So Well
Simple ways to switch up the recipe
Purple potato soup is more than a pretty bowl—it’s versatile, easy to customize, and plays well with a variety of flavors. Once you’ve made the base version, try these creative variations to keep things exciting:
- Smoky variation: Add smoked paprika and ground cumin while sautéing the leeks for a richer, deeper flavor.
- Herb-infused version: Stir in fresh thyme, dill, or rosemary just before serving for a bright, garden-fresh lift.
- Thai-style twist: Mix in red curry paste and a touch of ginger during cooking. Add a squeeze of lime juice and a splash of coconut cream to finish.
- Protein-boosted bowl: Top your soup with roasted chickpeas, cooked lentils, or cubed tofu for extra substance.
How purple potato soup compares to the classic kind
This dish doesn’t just stand out visually—it holds its own when it comes to nutrition, comfort, and versatility. Here’s a quick comparison:
| Feature | Purple Potato Soup | Traditional Potato Soup |
|---|---|---|
| Color | Vivid violet | Creamy white or beige |
| Main Fat Source | Coconut or olive oil | Butter or cream |
| Vegan Friendly | Yes | Rarely |
| Nutrition Boost | High in antioxidants (anthocyanins) | Higher in saturated fats |
Purple potatoes aren’t just eye-catching—they’re genuinely good for you. Their vibrant color comes from anthocyanins, natural plant compounds known to support blood vessel health, reduce inflammation, and offer antioxidant protection. A study highlighted by Medical News Today discusses how these properties may help lower blood pressure and support cardiovascular wellness.
Best serving suggestions
This soup shines in cozy, comforting meals or colorful dinner spreads. Here are a few pairing tips to make the most of it:
- Bread on the side: Crusty sourdough, olive-studded flatbread, or gluten-free seedy crackers are perfect for dipping.
- Toppings: Try crispy shallots, roasted seeds, or a swirl of non-dairy cream for texture and contrast.
- Drink pairing: Herbal teas like lemongrass or mint complement the soup’s earthy sweetness, while dry white wines like Sauvignon Blanc can enhance its brightness.
Storage Tips and the Joy of Cooking Purple Potato Soup
How to store it right
One of the best things about purple potato soup is how well it keeps. Make a big batch on Sunday, and you’ve got lunch or dinner ready for several days. Here’s how to store it safely and maintain flavor and texture:
| Storage Method | How Long | Best Practices |
|---|---|---|
| Refrigerator | Up to 5 days | Store in airtight glass containers to preserve color and flavor |
| Freezer | Up to 3 months | Leave 1-inch space at top of container for expansion |
| Reheating | As needed | Use stovetop over low heat; stir well to maintain creaminess |
Avoid microwaving from frozen—thaw overnight in the fridge or run the container under warm water until it loosens enough to pour into a pot. If the texture separates slightly after freezing, a quick blend will bring it right back together.

Frequently Asked Questions
Will purple potatoes make my soup purple?
Yes, absolutely. When you cook purple potatoes with their skins on and blend them into the soup, the natural pigments called anthocyanins create a vibrant violet color. The final hue can vary depending on the specific variety and whether you add coconut milk or broth, but the soup will always retain a gorgeous purple tone.
What is purple potato in Vietnamese cuisine?
In Vietnamese, purple sweet potato is often referred to as khoai lang tím. It’s a common ingredient in desserts, sticky rice, and colorful snacks. While not traditionally used in soup, its creamy texture and natural sweetness make it perfect for modern plant-based dishes like this one.
Are purple potatoes healthier than regular potatoes?
Purple potatoes have a slight edge in nutrition. They’re packed with anthocyanins, a type of antioxidant that’s also found in blueberries. These compounds have been linked to better blood pressure regulation, reduced inflammation, and improved circulation. They also have a lower glycemic impact compared to white potatoes, which helps stabilize blood sugar.
What was Julia Child’s favorite soup?
Julia Child was known for her love of classic French cuisine, and one of her favorite soups was potage parmentier—a creamy leek and potato soup. While hers was rooted in traditional techniques and heavy cream, this purple potato version offers a similar level of comfort with a more modern, plant-based twist.
