How To Cook Squash And Zucchini In Instant Pot

You can cook squash and zucchini in an Instant Pot by using just a few minutes of pressure cooking and a quick release.
 
It’s one of the fastest ways to get tender, flavorful vegetables on the table without standing over a hot stove.
 
Whether you’re working with yellow squash, butternut squash, or classic green zucchini, the Instant Pot makes the whole process almost effortless.
 
In this post, we’ll walk through exactly how to cook squash and zucchini in an Instant Pot, plus seasoning tips and common mistakes to avoid.
 

How to Cook Squash and Zucchini in an Instant Pot

Cooking squash and zucchini in an Instant Pot is simple once you know the right timing and method.
 
Here’s how the process breaks down step by step.
 

1. Wash and Cut Your Squash and Zucchini

Start by rinsing your squash and zucchini under cool running water to remove any dirt or grit.
 
Trim off the ends, then slice them into rounds, half-moons, or chunks depending on what you’re making.
 
Aim for pieces that are roughly the same size so they cook evenly in the Instant Pot.
 
If you’re cooking squash and zucchini together, keep in mind that zucchini tends to cook a touch faster than firmer squash varieties.
 

2. Add Liquid to the Instant Pot

Every Instant Pot recipe needs liquid to build pressure, so pour in about one cup of water or broth.
 
Broth adds extra flavor to your squash and zucchini, while water keeps things neutral and simple.
 
Place a steamer basket or trivet inside the pot so your vegetables sit above the liquid instead of boiling in it.
 
This is the key trick for cooking squash and zucchini in an Instant Pot without turning them into mush.
 

3. Load the Squash and Zucchini In

Pile your cut squash and zucchini into the steamer basket in an even layer.
 
Don’t pack them too tightly, because steam needs room to circulate around every piece.
 
If you’re cooking a big batch of squash and zucchini, work in two rounds rather than overcrowding the pot.
 

4. Set the Time and Pressure

Secure the lid, set the valve to sealing, and choose Manual or Pressure Cook on High.
 
For tender squash and zucchini, cook for just one to two minutes.
 
That’s right, cooking squash and zucchini in an Instant Pot takes almost no time at all.
 
For firmer slices that hold their shape, stick with one minute, and for softer pieces, go with two.
 

5. Do a Quick Release

Once the timer beeps, carefully switch the valve to venting for a quick release.
 
Quick release stops the cooking process right away, which keeps your squash and zucchini from overcooking.
 
Open the lid once the pin drops, then use tongs to transfer your vegetables to a serving dish.
 

Best Seasonings for Squash and Zucchini in an Instant Pot

Plain squash and zucchini are fine, but a little seasoning makes them shine.
 
Here are some tasty options to try after cooking squash and zucchini in an Instant Pot.
 

1. Garlic, Butter, and Parmesan

Toss the warm squash and zucchini with minced garlic, a pat of butter, and a sprinkle of Parmesan.
 
The heat from the vegetables softens the garlic and melts the butter beautifully.
 

2. Olive Oil, Lemon, and Herbs

A drizzle of olive oil, a squeeze of lemon, and fresh herbs like basil or parsley keeps things light and bright.
 
This combo works especially well when you cook squash and zucchini as a summer side dish.
 

3. Italian Seasoning and Red Pepper Flakes

A pinch of Italian seasoning plus red pepper flakes adds warmth and a gentle kick.
 
It’s an easy way to give your Instant Pot squash and zucchini a little personality.
 

Common Mistakes When Cooking Squash and Zucchini in an Instant Pot

Even a simple cook can go sideways, so watch out for these common slip-ups.
 

1. Cooking Them Too Long

The biggest mistake is overcooking squash and zucchini in an Instant Pot.
 
Even one extra minute can turn crisp-tender slices into soft, watery mush.
 

2. Skipping the Steamer Basket

Dropping squash and zucchini directly into the liquid makes them soggy.
 
Use a steamer basket so they cook in steam rather than soak in water.
 

3. Forgetting the Quick Release

Letting the pot sit on natural release keeps cooking your squash and zucchini.
 
Always use a quick release to lock in that perfect texture.
 

4. Overcrowding the Pot

Too many pieces stacked together means uneven cooking.
 
Give your squash and zucchini room to breathe, and they’ll reward you with even, tender results.
 

So, How Do You Cook Squash and Zucchini in an Instant Pot?

You cook squash and zucchini in an Instant Pot by adding a cup of liquid, using a steamer basket, and pressure cooking on high for one to two minutes with a quick release.
 
It’s fast, it’s easy, and it keeps both vegetables tender without turning them into mush.
