Instant Pot vegetable soup is a great way to make use of your pressure cooker! The soup is heart-healthy, full of flavor and ready in under 30 minutes! Plus, the entire recipe is made in the Instant Pot, so clean up is a breeze.
This Instant Pot vegetable soup is my FIRST Instant Pot recipe! See, I’d held off on getting an Instant Pot last year because it seemed super trendy and I was waiting to see if the trend was going to stick around or not. As it turns out, people are still as obsessed as they were last year, so I bit the bullet and bought the IP!
Lately, I’ve been playing around with it and figuring out the best uses for it. This article outlines a handful of common uses for the Instant Pot. Not surprisingly, one common use is soup, which I found to be super easy and intuitive.
Why this Instant Pot vegetable soup works
- It’s loaded with–wait for it–VEGETABLES, but is super flavorful and pairs perfectly with a slice of bread
- It comes together in 30 minutes total
- You only need one dish (the Instant Pot) for this recipe, so clean up is a breeze
What you’ll need
- Onion, garlic – An absolute must for almost any soup recipe.
- Carrots, celery, green beans – These make up the bulk of the vegetables, so I don’t recommend any substitutions.
- Parsley – Parsley adds even more flavor, so don’t skimp on it! If you have to, you can use dried parsley. Start with 2 tsp and then add more as needed.
- Russet potatoes – also called Idaho potatoes. You can peel them if you want, but it’s not necessary.
- Canned diced tomatoes – LOVE using fire roasted diced tomatoes because they have so much more flavor to them. In a pinch? Regular diced tomatoes work just fine, though if that’s what you use, I would add 1/4-1/2 tsp red pepper flakes to the Instant Pot.
- Italian seasoning – 1 tbsp may seem like a lot, but I pinky promise it’s the perfect amount.
- Vegetable broth – this is a no-brainer, but you need vegetable broth in order to make vegetable soup. No substitutions.
Step 1: Sauté the vegetables. Add 1-2 tbsp of olive oil to your Instant Pot, then add the onion, garlic, carrots, celery, parsley, and Italian seasoning and press “Sauté”. Sauté the vegetables for 3-5 minutes or until the onion is soft.
Step 2: Pressure cook the soup. Add the potatoes, green beans, diced tomatoes, vegetable broth, and a pinch of salt and pepper and stir to combine. Then, lock the lid in place and make sure the valve on top is on the “sealing” setting. Hit the “Pressure Cook” button and set the timer to 10 minutes.
It will take around 10 minutes for the Instant Pot to come to pressure, so don’t worry if it seems like nothing is happening at first.
Step 3: Naturally release the pressure. Once the 10 minutes is up, the IP will beep, and then begin a new timer to let you know that the pressure is naturally releasing. Naturally release the pressure for 5 minutes, then carefully switch the valve from “seal” to “vent”, which will manually release the rest of the pressure.
Once that’s done, carefully open the lid, then stir the soup. It should look something like this:
Is there a preferred way to dice the potatoes?
Not necessarily. The good thing about soup is that it’s pretty forgiving, and how you cut the vegetables doesn’t really matter. With that said, I chose to keep the potato skins on, and then I sliced the potatoes into rounds before cutting them into fourths.
How long does this soup need to cook?
Honestly, not long. The thing about vegetables in the Instant Pot is that they cook really quickly vs. meat, which takes a little longer to fully cook. You want the vegetables to be soft, but not soggy, so 10 minutes is the perfect amount of time!
How should I reheat this soup?
I recommend reheating it in a saucepan over the stove. It’s the quickest way, and it’s a good way to make sure the heat gets evenly distributed.
What should I serve this with?
Honestly, it’s pretty delicious on its own with a slice (or two!) of sourdough. Or, you could have it with a side of zucchini fritters, which is what we did and it was fantastic.

It will take 10 minutes or so for the pot to fully come to pressure, then it will begin counting down from 10.
- Once the timer beeps, that means the soup is done. Allow 5 minutes for the pressure to naturally release before carefully flipping the pressure release handle to "vent" mode and manually releasing the pressure. Slowly remove the lid, stir the soup and adjust the salt and pepper as needed.
