While this Instant Pot Thai-inspired soup with corn and zucchini is perfect all year round, we love making it in summer when fresh seasonal vegetables are at their best. Sweet corn and zucchini are always in abundance and if you’ve got a surplus in the kitchen, this gluten-free, vegan-friendly soup is a great way to use them up. It’s light, healthy and delicious and takes no time at all!
We love making this Thai-inspired Instant Pot in summer because it’s a great recipe to use up a variety of seasonal vegetables. Sweet corn and zucchini pair well together but the coconut curry broth would work well with any vegetable. Try diced carrots, pumpkin, broccoli, green beans, eggplant or peppers.
The recipe makes 3-4 portions, depending on what else you’re serving with the soup. To make this into a more satiating meal, you can add noodles, a protein of choice (tofu, tempeh, chickpeas) or rice crackers on the side.
HOW TO MAKE INSTANT POT CORN ZUCCHINI SOUP
As mentioned before, this soup takes no time at all. Summer vegetables need little cooking so the Instant Pot will only be used for about 10-12 minutes. The rest is just some brief chopping and getting the ingredients out of the pantry. Seriously, you can have this ready in 20 minutes or so.
You will find the full list of ingredients, instructions and a nutritional breakdown below. Here is a handy video for how to make this Thai soup with the Instant Pot. Stovetop instructions are also provided below.

Description
This gluten-free and vegan Instant Pot Thai soup with corn, zucchini and coconut is light, healthy and delicious and takes no time at all.
Ingredients
2 tablespoons olive oil
1 onion, diced
1 tablespoon diced, ginger
3 garlic cloves, diced
1/2 teaspoon salt
2.5 cups diced zucchini (1.5 large zucchini, diced – 2–3 cups)
1.5 cups sweet corn (2 corns (fresh or frozen) – 1.5 cups)
2 teaspoons curry powder
1 teaspoon turmeric powder
500 ml vegetable stock
To finish
1 cup coconut cream (it’s the thickened part of coconut milk)
2 tablespoons lemon juice or lime juice
1/3 cup chopped cilantro
Fried shallots (optional)
Instructions
- Turn the Instant Pot on and press the Saute function key. Once heated, add olive oil, onions, ginger and garlic to the pot and stir for 30-60 seconds.
- Add the rest of the ingredients (except for finishing ones) and stir through. Please note that the vegetables will also give out some liquid into the soup. Press Cancel to stop the Saute function.

- To finish the soup, add the lemon or lime juice, coconut cream and cilantro and stir through. Serve with extra chili, cilantro and fried shallots of extra crunch.
Notes
- As you can imagine, you can add a variety of veggies to the soup so choose whatever is in season. Diced carrots, pumpkin, broccoli, green beans, eggplant and peppers would all work in this soup.
- The recipe makes 3-4 portions, depending on what else you’re serving. To make this into a more satiating meal, you can add noodles, a protein of choice (tofu, tempeh, chickpeas) or rice crackers on the side.

If I increase the serving sizes, ex scale x 3 do i need to adjust cooking time as well? thanks!
Hey Lauren, cooking time can stay the same 🙂
Great soup! Proportions of ingredients are spot on…we like things spicy so I added some red curry paste and will also add some chili peppers!
★★★★★
Thanks, Natalie. Great idea to add a little extra curry paste for spice.
This is an amazing pot of Thai soup. Your proportions and instructions were spot on. I substituted stock with water as i did not have stock. I added a teaspoon red Thai curry paste and finished the rest exactly as you outlined. Thank you for this wonderful recipe.
★★★★★
Glad you enjoyed it 🙂
Any guidance on if this recipe freezes well? I have a TON of zucchini right now and would love to enjoy this soup in the winter. Thoughts?
Yes, it should freeze well. The coconut cream may separate and congeal from the rest of the liquid and the zucchini might dissolve. But I would do a small batch test run to freeze just to make sure when it thaws it still taste how you prefer.
This was easy and delicious! I found it when looking for ways to use part of my bumper crop of zucchini. I substituted Evaporated milk for the coconut milk with no loss of flavor and a very nice creaminess. I also added about 2 cups of fresh chopped kale from the garden. It added a nice chewiness. I put it in with the zucchini and the corn. We loved the curry and turmeric flavors and the corn (I used frozen) added a nice amount of sweetness. This will be a staple!
We had some leftover “Thai chicken Bowl” from a restaurant. This was a wonderful addition as it added spiced chicken, chili pepper, crunch from cabbage, and some rice. It was a great way to make this more of a main dish..
★★★★★
Happy this was a nice addition to your meal.
The first time I made this it was so easy and quick that I was really suspicious but it is AMAZING! Make it all the time, often add chickpeas at the end, and OKAY hear me out, I add beer bratwurst to it and its friggin CRAZY GOOD. Defs recommend this recipe!!
★★★★★
Thank you so much for your kind feedback. Glad you made it and it’s become a go-to. Love the addition of chickpeas and what a surprise twist with the beer bratwurst. Wouldn’t have thought of adding it in but sounds like it works well. Plus, extra protein!
This looks awesome. Do you have any suggestions for a coconut cream substitute?
If you tolerate dairy, heavy cream or sour cream could be used.
