Let’s skip the part where detox soup means drinking something that tastes like lawn clippings and makes you feel sorry for yourself. This Easy Vegan Detox Green Vegetable Soup is a genuinely delicious, colourful, chunky-meets-creamy bowl of summer vegetables in a turmeric-spiced, coconut-kissed broth — and it happens to be low calorie, gluten-free, low FODMAP, and ready in 30 minutes. The “detox” here isn’t marketing fluff. It’s real vegetables doing real nutritional work, in a soup you’ll actually want to eat.
I make this after weekends that got slightly out of hand, or on Monday evenings when I want something that genuinely resets my system without punishing my taste buds. Bell peppers, carrots, zucchini, summer squash, turmeric, lime, and fresh cilantro — one Dutch oven, 30 minutes, four generous bowls. Completely vegan, completely satisfying. Let’s get into it.

The Full Ingredient List
- 2 tablespoons olive oil or coconut oil
- 2 medium yellow or orange bell peppers, finely diced
- 2 medium carrots, finely diced
- 4 scallions (spring onions), white and green parts separated, thinly sliced
- 2 medium zucchini (about ¾ lb), finely diced
- 2 medium summer squash (about ¾ lb), finely diced
- 2 teaspoons sweet paprika
- 2 teaspoons ground turmeric
- 1 can (5.4 oz) unsweetened coconut cream (optional — adds richness)
- 1 quart (4 cups) vegetable stock
- 2 teaspoons sea salt
- 2 tablespoons fresh lime juice
- ¼ cup fresh cilantro, roughly chopped
How to Make It – Step by Step for Easy Vegan Detox Green Vegetable Soup
Step 1: Heat the olive oil or coconut oil in a large Dutch oven over medium-high heat. Add the diced bell peppers, carrots, and the white parts of the scallions. Sauté for 7–10 minutes, stirring occasionally, until the vegetables start to brown and caramelise at the edges. This browning step is where a significant amount of flavour develops — don’t rush it.
Step 2: Stir in the diced zucchini, summer squash, sweet paprika, and ground turmeric. Cook for 4 minutes more until the spices are very fragrant and the squash begins to soften. The turmeric will turn everything a gorgeous golden colour at this point.
Step 3: Pour in the coconut cream (if using) and the vegetable stock. Add the sea salt and scrape up any browned bits from the bottom of the pan — those bits are flavour and you want them in the soup. Bring to a rapid simmer over medium-high heat and cook for about 5 minutes until the squash is fork-tender but still has some bite. Don’t overcook — mushy summer squash is not the goal.
Step 4: Remove the pot from the heat. Stir in the lime juice and half the chopped cilantro.
Step 5: Using an immersion blender, partially blend the soup — purée about half while leaving the other half chunky. This creates a chowder-like texture that’s thicker and more satisfying than a clear broth but still has plenty of vegetable texture throughout.
Step 6: Ladle into bowls, garnish with the remaining cilantro and the green parts of the scallions. Serve immediately.
Equipment You’ll Need
- A large Dutch oven — this is the recipe’s specified equipment and the ideal pot for it. A Dutch oven’s thick base distributes heat evenly, which is exactly what you need for the initial caramelising step. The heavy construction prevents hot spots that would burn the vegetables before they properly soften. A large saucepan or heavy-bottomed pot works as a substitute, but a Dutch oven produces noticeably better caramelisation.
- An immersion (stick) blender — for the partial blending step. The immersion blender is the right tool here because you’re blending directly in the pot and you want control over how much gets blended. A Cuisinart, Braun, or Ninja immersion blender all work perfectly. The goal is to blend roughly half the soup — dip the blender into one side of the pot and pulse until that side is smooth, leaving the other side chunky.
- A standard blender — if you don’t have an immersion blender. Transfer half the soup carefully to a blender, blend until smooth, and return to the pot. Be careful with hot liquid — fill the blender no more than halfway, hold the lid firmly, and start on low speed.
- A sharp knife and large chopping board — you’re finely dicing a significant quantity of vegetables, so a sharp knife and a stable board make real difference to how enjoyable the prep is
- Measuring spoons for the spices, salt, and lime juice
- A wooden spoon or spatula for stirring and scraping
The Dutch oven is worth mentioning specifically. If you cook soups and stews regularly and don’t own one, this recipe is a good reason to change that. The difference in caramelisation between a Dutch oven and a thin saucepan is significant enough to affect the final flavour of the soup meaningfully.

At 165–220 calories per serving depending on whether you use the coconut cream, this soup delivers exceptional nutritional value for very few calories. The bell peppers alone provide over 150% of your daily vitamin C per serving. The carrots add beta-carotene. The turmeric adds curcumin — one of the most studied anti-inflammatory compounds in food. The zucchini and summer squash contribute potassium, folate, and water content that supports hydration.
FYI: This soup is specifically designed to be low FODMAP, which means it’s gentle on digestive systems and suitable for people with IBS or other digestive sensitivities. The scallions (spring onions) are used specifically because the green parts are low FODMAP, while regular onion and garlic are not. If you’re cooking strictly for FODMAP concerns, use only the green parts of the scallions.
Why This Soup Actually Deserves the Word “Detox”
The word “detox” gets thrown around so carelessly in food content that it’s worth explaining what’s actually happening nutritionally in this soup — because the claim here has genuine substance.
Turmeric and Curcumin
Two teaspoons of ground turmeric provides a meaningful dose of curcumin, the active compound in turmeric that has been extensively studied for its anti-inflammatory and antioxidant properties. Chronic, low-grade inflammation underlies many modern health conditions, and regularly consuming anti-inflammatory foods like turmeric is one of the most evidence-based dietary strategies for supporting long-term health. This isn’t wellness marketing — curcumin is genuinely one of the most researched bioactive compounds in nutrition science.
Bell Peppers and Vitamin C
Two medium bell peppers provide an extraordinary amount of vitamin C — one of the most powerful antioxidants the human body uses. Vitamin C supports immune function, collagen synthesis, skin health, and iron absorption. Yellow and orange bell peppers contain even more vitamin C than red ones, and significantly more than green peppers. Using yellow or orange specifically is a deliberate nutritional choice.
Zucchini and Summer Squash for Hydration
Both zucchini and summer squash are over 90% water by weight, which means this soup actively supports hydration — particularly valuable in summer when heat increases fluid loss. They also provide potassium, which regulates fluid balance and blood pressure, and manganese, which supports bone health and metabolic function.
Lime Juice and Liver Support
Fresh lime juice contains citric acid and vitamin C, both of which support liver function. The liver is your body’s primary detoxification organ — supporting it with antioxidant-rich foods like lime juice is genuinely meaningful, not metaphorical. Adding lime juice off the heat rather than during cooking preserves these compounds at their most active.
The Partial Blending Technique — Why It’s the Right Call
Most detox soups either fully blend into a purée or stay completely broth-based with whole vegetables. This recipe does something more interesting: partial blending creates a soup that’s simultaneously thick and chunky — what the recipe accurately describes as “chowder-like.”
Why Chowder-Like Is Better Here
A fully blended soup is satisfying but can feel one-dimensional — every spoonful is identical. A purely broth-based soup with whole vegetables can feel thin and insubstantial when you’re looking for something comforting. The partial blend gives you the best of both: a thickened, creamy base from the blended half, with satisfying vegetable chunks throughout that give each bowl texture and visual interest.
How to Get the Texture Right
Dip the immersion blender into one side of the pot — roughly half the surface area — and blend until smooth. Then lift it out and leave the other half completely untouched. Stir gently to combine the smooth and chunky halves, which creates a consistent chowder texture throughout rather than distinct zones of purée and broth.
If using a regular blender, ladle out approximately half the soup, blend until smooth, and return it to the pot. Stir to combine. The result is essentially the same.
Breaking Down Every Ingredient — Why Each One Earns Its Place
Yellow or Orange Bell Peppers
These are the flavour and colour foundation of the soup. Yellow and orange peppers are sweeter and milder than red or green, which makes them better suited to a detox soup where you want clean, bright flavour without bitterness. They caramelise beautifully in the initial sauté step, developing a sweetness that becomes the soup’s base note.
Carrots
Carrots add natural sweetness, beta-carotene (which converts to vitamin A in the body), and a subtle earthiness that anchors the lighter summer vegetables. They take the longest to soften, which is why they go in first during the sauté. Finely diced carrots become tender during the cooking time without going mushy.
Scallions (Spring Onions) — White and Green Parts Used Differently
This is the most thoughtful ingredient choice in the recipe. The white parts go in at the start of cooking with the other aromatic vegetables — they soften and develop flavour during the sauté. The green parts are reserved for garnishing — added raw at the end for a fresh, peppery bite and a visual pop of green. Using both parts in different ways extracts maximum flavour and colour from a single ingredient.
Zucchini and Summer Squash
Using both types of squash isn’t redundant — they have slightly different textures and flavours that create a more interesting soup than using just one. Summer squash is slightly firmer and more mild; zucchini is slightly softer and has a faintly greener flavour. Together they add substance without calories, which is essentially the goal of a detox soup.
Sweet Paprika
Sweet paprika adds a warm, slightly smoky depth that prevents the soup from tasting flat or vegetable-broth-bland. Two teaspoons is generous but correct — you want to taste it. Smoked paprika is an excellent substitution if you want a more pronounced smoky note.
Ground Turmeric
Two teaspoons colours the soup golden and delivers the anti-inflammatory benefits discussed above. Turmeric pairs naturally with the coconut cream — the fat in coconut cream actually improves curcumin absorption, which is another reason the coconut cream option is worth considering even in a “light” soup.
Coconut Cream — Optional but Excellent
The small can of coconut cream is optional, and the soup is genuinely good without it. But with it, the texture shifts from a vegetable broth with substance to something genuinely creamy and more satisfying. A 5.4 oz can is a smaller, more concentrated format than a full can — it adds richness without making the soup heavy. If you’re strictly managing calories, skip it. If you want a more indulgent result, include it.

Tips for Making This Detox Soup Absolutely Perfect
- Don’t rush the initial sauté. The 7–10 minutes of caramelising the bell peppers, carrots, and scallion whites is where the soup’s depth of flavour comes from. Rushing this step produces a soup that tastes like vegetables simmered in broth rather than one with a proper, complex flavour base.
- Dice everything finely and consistently. Consistent small dice means everything cooks evenly in the same timeframe. Large irregular chunks mean some pieces are overcooked while others are still firm.
- Scrape the bottom of the pot when you add the stock. Those brown bits stuck to the bottom of the Dutch oven are concentrated flavour — scraping and dissolving them into the broth adds depth that you’d otherwise lose.
- Don’t overcook the squash. Five minutes of rapid simmering is all the zucchini and summer squash need. They should be fork-tender but still holding their shape. Over-cooked squash goes mushy and slightly bitter.
- Add lime juice off the heat. Once you remove the pot from the heat, add the lime juice immediately. The residual heat distributes the lime flavour through the soup without cooking off the bright citrus notes.
- Taste at every stage. Detox soups can taste flat and watery if under-seasoned. Season the oil, season with the spices, season the broth, and taste after blending. Salt is not the enemy here — it’s what makes the vegetables taste like themselves.
Why This Works as a Summer Soup Specifically
Summer is the perfect time for this Vegan Detox Green Vegetable Soup for reasons that go beyond the seasonal vegetables.
The Vegetables Are at Peak Quality
Bell peppers, zucchini, and summer squash are all peak-summer vegetables. In July and August, they’re sweeter, more vibrant, and more flavourful than at any other time of year. A recipe built around these vegetables specifically deserves to be made now, when the ingredients are at their absolute best.
It’s Light Enough for Hot Weather
At 165–220 calories per serving, this soup doesn’t sit heavily after eating — which matters when summer heat already reduces your appetite. It hydrates you from the inside (all those water-rich vegetables) while still providing enough substance to function as a proper meal with some bread or a side salad.
The Lime and Cilantro Are Refreshing
The lime juice and fresh cilantro finish gives the soup a brightness and freshness that feels genuinely appropriate for warm weather eating. These aren’t just flavour additions — they change the character of the soup from warming winter fare to something vibrant and summer-suitable.
Variations to Try
Protein-Boosted Version
Add a can of drained chickpeas or white beans to the pot with the vegetable stock. The beans add protein and fibre that make this soup substantially more filling while staying within the spirit of a clean, light detox meal.
Spiced-Up Version
Add ½ teaspoon of cayenne pepper or a minced fresh chilli with the paprika and turmeric. The heat amplifies the detoxifying effect (capsaicin supports circulation and metabolism) and makes the soup considerably more exciting.
Ginger Addition
Add 1 teaspoon of freshly grated ginger with the garlic stage (or in this recipe, with the spices). Ginger and turmeric together are one of the most powerful anti-inflammatory food combinations you can consume, and the flavour combination against the lime and cilantro is excellent.
Fully Blended Version
If you prefer a completely smooth soup, blend the entire pot rather than just half. The result is more like a silky vegetable bisque — still delicious, just a different texture experience.
Added Greens
Stir a large handful of baby spinach or kale into the soup immediately after removing it from the heat. The residual heat wilts the greens in about 60 seconds, adding extra iron, vitamin K, and a deeper green colour without any additional cooking time.
How to Store and Reheat
Refrigerator
The soup keeps well for 3–4 days in the fridge in a sealed container. The flavours actually deepen on day 2 as the spices continue to infuse. Reheat gently over medium-low heat, stirring frequently. Add a small splash of vegetable stock if the soup has thickened too much overnight.
Freezer
This soup freezes well for up to 3 months. The zucchini and summer squash do soften slightly after freezing and thawing, but the overall flavour and satisfaction of the bowl remains excellent. Thaw overnight in the fridge and reheat as above.
Storage tip: If you’re making this specifically for meal prep, hold back the lime juice and cilantro and add them fresh when you reheat each portion. This keeps the bright, fresh character intact rather than having it fade during storage.
Serving Suggestions
This soup stands alone beautifully, but thoughtful accompaniments make it a more complete meal:
- Crusty sourdough or seeded bread — for dipping into the broth
- A simple green salad alongside for a light lunch
- Warm flatbread for a more substantial dinner
- Extra lime wedges on the side so everyone can adjust the acidity to their taste
- Toasted pumpkin seeds scattered on top for crunch and extra zinc
- A swirl of additional coconut cream for a more indulgent presentation
Frequently Asked Questions
Is this really low FODMAP? The recipe is designed to be low FODMAP — it uses scallion greens rather than onion or garlic, and the vegetables chosen are all low FODMAP. If you’re following a strict low FODMAP protocol, use only the green parts of the scallions and ensure your vegetable stock is certified low FODMAP (many stocks contain onion or garlic powder).
Can I use dried herbs instead of fresh cilantro? Fresh cilantro is strongly preferred — dried cilantro has a flat, almost hay-like flavour that doesn’t contribute the same freshness. If cilantro isn’t your thing (it divides people strongly), fresh flat-leaf parsley is a genuinely good substitute with a similar fresh, herbal character.
Can I make this in an Instant Pot? Yes — use the sauté function for the initial caramelising step, then add the remaining ingredients and pressure cook on high for 3 minutes with a quick release. Partial blend as directed. The caramelisation in an Instant Pot won’t be quite as deep as in a Dutch oven, but the soup will still be very good.
What if I don’t have summer squash? Use additional zucchini — the soup will be essentially identical. You can also substitute yellow crookneck squash, patty pan squash, or any other mild summer squash variety.
Is this soup filling enough as a main course? For a light lunch, yes — especially with bread. For a more substantial dinner, add protein (chickpeas, white beans, or tofu) and serve with something alongside.
