If there’s one vegetable that shows up relentlessly in a summer garden, it’s zucchini. One week you’re planting tiny seeds, and the next you’re wondering what to do with a counter full of green squash. This Creamy Vegan Zucchini Soup is one of my absolute favorite ways to use up that summer harvest.
It’s silky smooth, surprisingly rich, and comes together on the stovetop in under 30 minutes with just a handful of simple ingredients. I love serving it warm with a slice of crusty bread, but it’s also incredible served chilled on a hot day. No matter how you serve it, this easy vegan soup is bright, fresh, and full of garden flavor.

Why You’ll Love This Soup
Garden-Fresh and Seasonal
Zucchini is one of the most prolific summer garden vegetables. This recipe is the perfect way to put that abundance to delicious use. You can go from garden to bowl in under 30 minutes.
Incredibly Creamy — Completely Dairy-Free
The secret to this soup’s silky texture is a combination of the zucchini itself (it blends beautifully) and a splash of full-fat coconut milk stirred in at the end. It’s rich and velvety without any cream, butter, or cheese.
Serve It Warm or Chilled
This is one of the most versatile vegan summer soups out there. Serve it warm for a light weeknight dinner, or refrigerate it for a few hours and enjoy it cold as a refreshing chilled summer soup. Both ways are absolutely delicious.
Simple and Quick
With just one pot, an immersion blender, and about 30 minutes, you have a beautiful, restaurant-quality soup on the table. It’s naturally vegan, gluten-free, and made from ingredients you likely already have on hand.

MY FAVORITE EQUIPMENT TO MAKE THE SOUP EASY
Food Chopper
A good food chopper makes quick work of the onion and zucchini. My go-to is the Fullstar Vegetable Chopper. It chops everything evenly and saves so much time.
Small Vegetable Chopper
For quickly mincing the garlic, I use the OXO Good Grips Vegetable Chopper. It handles small batches perfectly and is easy to clean.
Immersion Blender
This is the key tool for making this soup silky smooth right in the pot. No need to transfer to a blender and no extra dishes. My Cuisinart Immersion Blender is one of my most-used kitchen gadgets, especially for soups like this one.
DIRECTIONS
1. Prep the Ingredients
Roughly chop the zucchini, no need to peel it, the skin blends right in and adds beautiful color to the finished soup. Chop the onion and mince the garlic. That’s really all the prep work involved!
2. Sauté the Aromatics
Heat 2 tablespoons of olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion and sauté for 4–5 minutes until softened and translucent. Add the minced garlic and cook for another 1–2 minutes until fragrant.
3. Add the Zucchini and Spices
Add the chopped zucchini to the pot along with the salt, black pepper, garlic powder, and ground cumin. Stir everything together and cook for about 5 minutes, stirring occasionally, until the zucchini begins to soften slightly.
4. Add the Broth
Pour in the vegetable broth and stir to combine. Bring the soup to a gentle boil, then reduce the heat to medium-low. Cover and simmer for 12–15 minutes, until the zucchini is completely tender and easily pierced with a fork.
5. Add the Fresh Basil
Remove the pot from heat and add the fresh basil leaves, stirring them into the hot soup. They’ll wilt right in and infuse the soup with fresh summer flavor.
6. Blend Until Smooth
Use an immersion blender to blend the soup directly in the pot until completely smooth and silky. Alternatively, carefully transfer the soup in batches to a blender, blend until smooth, and return it to the pot. Be cautious with hot liquid in a blender. Leave the lid slightly vented and hold it down with a towel.
7. Stir in Coconut Milk and Lemon
Stir in the coconut milk and fresh lemon juice. The coconut milk adds richness and creaminess, while the lemon brightens everything up beautifully. Taste and adjust salt and pepper as needed.
8. Serve and Garnish
Ladle the soup into bowls and garnish with a drizzle of coconut milk, a few fresh basil leaves, a sprinkle of red pepper flakes, and toasted pumpkin seeds if desired. Serve warm — or see below for how to serve it chilled!
Can I Serve This Soup Cold?
Absolutely! I highly recommend it! This creamy zucchini soup is one of the best cold soups for summer. Let the soup cool to room temperature after blending, then refrigerate it for at least 2–3 hours (or overnight). Serve it straight from the fridge, garnished with a swirl of coconut milk, fresh basil, and a squeeze of extra lemon. It’s light, refreshing, and incredibly satisfying on a hot day.
Can I Make This in the Instant Pot?
Yes! To make this in the Instant Pot, set it to “Sauté” mode and follow steps one through four as written above, adding the broth last. Secure the lid, set the valve to “Sealing,” and pressure cook on High for 5 minutes. Allow the pressure to release naturally for 5 minutes, then do a quick release. Add the basil, then blend with your immersion blender, stir in the coconut milk and lemon juice, and serve.

Instructions
- Roughly chop the zucchini, onion, and mince the garlic. No need to peel the zucchini — the skin adds color and blends beautifully.

- Add the chopped zucchini, salt, black pepper, garlic powder, and cumin. Stir to combine and cook for 5 minutes until the zucchini begins to soften.
- Pour in the vegetable broth, stir, and bring to a gentle boil. Reduce heat to medium-low, cover, and simmer for 12–15 minutes until the zucchini is completely tender.
- Remove from heat. Add the fresh basil leaves and stir them in.

Notes
- To serve chilled: Cool the soup completely, then refrigerate for 2–3 hours or overnight. Stir before serving and adjust seasoning — cold soups often need a touch more salt and lemon.
- Storage: Store in an airtight container in the refrigerator for up to 4 days, or freeze in portions for up to 3 months.
- Substitutions: Swap coconut milk for cashew cream or a neutral plant-based cream for a different flavor profile. Fresh dill can replace basil for an herby twist.
- Make it heartier: Stir in a can of drained white beans before blending for added protein and thickness.
