Why You Need This Recipe
- It goes with everything. You can serve it alongside pasta or on top of an omelette. Use it to top grilled chicken or stir it into rice or quinoa. I mean it when I say it’s delicious in so many things.
- Summertime brings an abundance of squash, especially zucchini squash. My neighbors are often gifting me with their squashes and this is my go-to recipe to use them up.
- The pressure cooker is a great way to cook squash because it works so fast and doesn’t heat up your kitchen.
Key Ingredients
- Zucchini has a mild, sweet flavor that plays well with other vegetables.
- Zucchini can be found year round but is in season during the summer months. See my related recipe for Instant Pot Zucchini Slices which can be frozen.
- Diced tomatoes add sweetness and acidity to the dish.
- Onion soaks up the juices of the tomatoes and pair perfectly with the zucchini.
- Garlic has a nutty, sweet, and mild flavor once cooked that goes exceptionally well with vegetables.
- Spices like sea salt are essential to bring out the flavors in the dish but red pepper flakes, dried basil, and black pepper give it something extra special.

Recipe Tips
- If you aren’t on a dairy-free or vegan diet, feel free to serve this dish with some freshly-grated Parmesan cheese on top. For dairy-free and vegan, you can use a dairy-free Parmesan cheese alternative (or just leave it out).
- The total cooking time includes approximately 10 minutes for the Instant Pot to come up to pressure and 10 minutes of natural pressure release.
- Store any leftovers in a covered container in the refrigerator for up to 4 days. Reheat before serving.
Recipe FAQs
No, in fact you should keep it on because it contains healthy vitamins and minerals, plus it’s thin, tender and flavorful. But, you can feel free to peel the zucchini if you wish.
Yes, you can use any type of summer squash in this recipe, including yellow squash.
You can use frozen zucchini, but it may become more mushy once cooked. You don’t typically need to adjust the cooking time, as the Instant Pot will just take a bit longer to come up to pressure.
Yes, the Instant Pot has a “Sauté” function. After adding a bit of oil and allowing it to heat up, you can add your sliced zucchini and sauté for a few minutes until it reaches your desired doneness. For this recipe, I like to use the pressure cook method though.

I’ve made this twice and it made soup both times. Is it because I’m not adding the onion?
Did you add water or liquid?
Many thanks for a super- pro squash recipe! Shared widely- 5 stars! *****
I noticed there isn’t any liquid except the juice from the canned tomatoes. Is this correct??
Thank you
Stephanie
Yes, exactly!
I am glad I made a double batch of this, because it is tasty. I did not see the comment about not peeling the zuchinni until I came one here. I saw the recipe originally.on fb InstantPot 101 for Beginners.
Could I through a frozen precooked chicken thigh on top of this to heat it up in the instant pot?
Ohhhh great question! I haven’t tried that but please let me know if you do!
I did throw the ore cooked frozen chicken thighs (2) in, there was a bit of broth in with them…turned out fabulous, what a delish quick meal. Thanks for the recipe.
Yay, I’m so glad to hear that!!!
Such a simple and great summer recipe.
Can you use fresh tomatoes instead of canned? Would you need to add liquid or cooking time? We have an abundance of tomatoes in our garden right now!
Great question! I have not tested it with fresh tomatoes. You would definitely need to add some liquid otherwise you will get a burn notice.
