You know that feeling when you want something that’s light but still genuinely satisfying? When you crave vegetables but don’t want to eat sad salad for the third time this week? That’s exactly what Easy Vegan Pea and Mint Soup delivers.
This is British comfort food at its finest—fresh spring peas, aromatic mint, a silky potato base, and a vegan buttermilk swirl that adds tangy richness without a single animal product. The whole thing comes together in 35-40 minutes, and it tastes like something you’d pay $18 for at a fancy restaurant.
I discovered this soup while craving that very specific British elegance that pea and mint somehow captures perfectly. It’s the kind of dish that makes you feel sophisticated while barely breaking a sweat in the kitchen. The best part? You can serve it warm on a cool evening or chilled when the sun is blazing. It’s genuinely flexible while tasting intentional and carefully crafted.
Why Easy Vegan Pea and Mint Soup Is Your New Summer Obsession
Here’s what I love about Easy Vegan Pea and Mint Soup: it proves that light doesn’t mean boring. This soup is bright, fresh, and bursting with flavor despite being incredibly simple. The peas contribute natural sweetness and creaminess when blended. The mint brings freshness and complexity. The vegan buttermilk adds tangy richness. Everything comes together into something that feels fancy but tastes totally approachable.
Ever wondered why pea and mint is such a classic combination? Because they genuinely complement each other perfectly. Mint’s brightness cuts through the peas’ natural sweetness, while the peas’ creaminess grounds the mint’s sharpness. Together, they create balance. Add in the subtle earthiness of potato and the aromatic punch of spring onions, and you’ve got a soup that tastes sophisticated without trying too hard.
This soup is 100% vegan, which means every ingredient comes from plants. The buttermilk? Made from plant milk and vinegar. The stock? Vegetable-based. Even the subtle richness you taste comes entirely from plants. You’re not eating a “vegan version” of something—you’re eating elegant, intentional plant-based cooking that happens to be absolutely delicious.
Understanding the Key Ingredients Creating Pea Magic
Spring Peas: Your Flavor Star
You’ve got two options here: 2 pounds of fresh peas in the pod (if you can find them at farmers’ markets during spring) or 250 grams (roughly 1â…“ cups) of frozen peas. Fresh is incredible if you can get it—shelling them feels like a little meditation, and they taste so vibrant. But honestly? Frozen peas are picked at peak ripeness and frozen immediately, so they’re often fresher than “fresh” peas that have been sitting around. Don’t feel bad choosing frozen.
You set aside 3 tablespoons of raw peas for garnish—these stay bright green and add textural contrast. The rest get blended into creamy goodness.
Fresh Mint: The Brightness Element
You’re using 4 tablespoons of chopped fresh mint, which is a generous amount. This isn’t a whisper of mint—it’s a proper fresh herb situation. Fresh mint brings cool, clean, slightly peppery notes that make your palate wake up. Don’t substitute dried mint. The difference is massive, and you deserve better.
Vegan Buttermilk: The Tangy Secret Weapon
This is your wild card. You make it by mixing plant milk with vinegar or lemon juice, creating tanginess without dairy. It adds richness, creaminess, and a subtle tang that professional kitchens have known about forever. The buttermilk doesn’t overpower—it just rounds out all the flavors and adds sophistication.
Potato: The Creamy Foundation
One medium potato creates natural creaminess when blended. You don’t need cream, dairy, or anything fancy. The potato’s starch does all the heavy lifting, creating silkiness while keeping the soup light. This is why this recipe works beautifully as a light dinner.

- Servings: 4-6 servings (depending on portion size)
- Total Time: 35-40 minutes
- Cuisine: British
- Calories per serving: Approximately 120-150 kcal (depending on serving size and vegan buttermilk amount)

Full Ingredients List
- 1 bunch spring onions, trimmed and roughly chopped (about 5-6 spring onions)
- 1 medium potato, peeled and diced (about ¾ cup)
- 1 garlic clove, crushed
- 850ml (3½ cups) vegetable stock (good quality makes a difference)
- 900g (2 lbs) young peas in the pod OR 250g (1â…“ cups) frozen peas
- 3 tablespoons peas, reserved for garnish (set aside before cooking)
- 4 tablespoons chopped fresh mint (genuine fresh mint, not dried)
- Large pinch caster sugar (just a tiny bit to balance flavors)
- 1 tablespoon fresh lemon or lime juice (for brightness)
For the Vegan Buttermilk:
- 150ml (½ cup + 2 tablespoons) unsweetened soya milk (or other plant milk like almond or oat)
- 2 teaspoons of ONE of these: lemon juice, apple cider vinegar, or white vinegar (creates the tang)
The Step-by-Step Process for Easy Vegan Pea and Mint Soup
Step 1: Make Your Vegan Buttermilk (5 Minutes)
In a jug, combine the plant milk with your chosen acid (lemon juice, apple cider vinegar, or white vinegar). Stir with a fork or whisk and let it sit for a minute. You’ll notice the milk slightly thickening and curdling slightly—that’s exactly what you want. This creates that tangy buttermilk flavor without dairy. Set it aside for now.
Step 2: Build Your Flavor Base (15 Minutes)
Put the spring onions into a large pan along with the diced potato, crushed garlic, and vegetable stock. Bring everything to a boil over medium-high heat. Once it’s boiling, reduce the heat and simmer for 15 minutes, or until the potato becomes very soft and almost breaks apart when you stir it.
Why this timing? The potato needs to fully soften so that when you blend it, it creates creaminess. Undercooked potato won’t blend smoothly and will create a grainy texture. You want it genuinely tender.
Step 3: Prepare Your Garnish Peas (2-3 Minutes)
While the base is simmering, put those 3 tablespoons of reserved peas into a separate small pot with water. Cook them for 2-3 minutes until just tender but still bright green. Drain them and immediately place them in a bowl of cold water. This stops the cooking and keeps them brilliant green. These are your garnish—they add visual appeal and a fresh, sweet burst of flavor.
Step 4: Add the Remaining Peas (3-4 Minutes)
After the potato has simmered for 15 minutes, add the remaining peas to the soup base. Simmer for 3-4 minutes. Don’t overcook—you want the peas to stay bright green and maintain their fresh flavor. Overcooked peas turn gray and taste mushy. Precision here matters.
Step 5: Create the Magic (Blend and Season)
Stir in the mint, caster sugar, and lemon or lime juice. Cool the soup slightly (this prevents the blender from exploding), then blend to your preferred consistency. Some people love a completely smooth soup. Others prefer a slightly chunky texture. You’re in control here—blend until it feels right to you.
Once blended, stir in half of the vegan buttermilk mixture. Taste and season generously with salt and pepper. The soup should taste bright, fresh, and slightly tangy.
Step 6: Decide: Hot or Cold?
Here’s where this soup gets flexible. For serving warm: Simply reheat gently on the stovetop without boiling. (The buttermilk will curdle if you boil it—keep the heat gentle.)
For serving cold: Cool the soup quickly (you can place the pot in an ice bath), then chill completely in the refrigerator.
Step 7: Serve and Celebrate
Ladle the soup into bowls. Top each bowl with a small dollop of the remaining vegan buttermilk and scatter the reserved peas over the top. Add a crack of black pepper and maybe a tiny mint leaf if you’re feeling fancy.

Pro Tips for Nailing This Recipe
1. Use Fresh Mint—No Exceptions
Dried mint is dusty and musty. Fresh mint is bright and alive. This is not a place to compromise. If you can’t find fresh mint, use fresh parsley mixed with a tiny bit of dried mint.
2. Don’t Overcook the Peas
I cannot stress this enough. 3-4 minutes is the maximum. Overcooked peas turn gray and lose their brightness. Set a timer and stick to it.
3. Make the Buttermilk Correctly
The ratio matters. Too much vinegar tastes too sharp. Too little doesn’t create enough tang. Follow the recipe 2 teaspoons of acid to 150ml of plant milk is the sweet spot.
4. Cool the Soup Before Blending
Hot soup can be dangerous in a blender. Let it cool for just a minute or two, then blend. Always blend with the lid slightly ajar (or cover loosely with a towel) to let steam escape.
5. Don’t Boil After Adding Buttermilk
If you’re reheating the soup, keep the heat medium and don’t let it boil. Boiling will curdle the vegan buttermilk and ruin the texture.
6. Taste and Adjust
After blending, taste the soup. Do you want more lemon brightness? Add it. More salt? Add it gradually. This is your soup make it perfect for your palate.
Variations and Customizations
Creamier Version: Add an extra ½ cup of plant milk or a splash of vegan cream at the end for extra silkiness.
Chunkier Texture: Blend only half the soup, then stir the blended portion back into the unblended portion. This creates a chunky-creamy hybrid.
Different Herbs: Basil works beautifully instead of mint. Parsley creates a different but still delicious flavor profile. Fresh dill is also incredible.
Add-Ins: Toast some breadcrumbs or croutons for crunch. Add crispy chickpeas for protein. Even a drizzle of good olive oil at the end adds richness.
Storage and Make-Ahead Strategy
Refrigerator Storage: Cool the soup completely, then store in airtight containers for up to 5 days. Store the vegan buttermilk separately add it fresh when serving.
Freezing: Cool completely, then freeze in portion-sized containers for up to 3 months. Thaw overnight in the fridge. Don’t freeze with the buttermilk garnish make that fresh.
Make-Ahead Tips: You can prep all ingredients the day before chop the vegetables, measure out the mint, even make the vegan buttermilk. On cooking day, it’s just assembly and cooking.
