As we put the holiday season behind us, I’m always ready for some cleansing food. I love the decadent treats that fill my Decembers, but my body is much happier when I get back to normal after the holidays.

I like to re-focus on getting lots of veggies of all colors into my diet in the new year, and this soup is a great place to start. I love how quickly this soup comes together in the Instant Pot. It takes just 10 minutes to cook, and you can even lower that cook time to 7 or 8 minutes for crisper veggies.

This Instant Pot vegetable soup is a delicious side dish or appetizer that goes well with many types of meals. It also makes a great light lunch.

Instant Pot Vegetable Soup Tips & Frequently Asked Questions

What are the best vegetables to put in soup?

This Instant Pot vegetable soup is full of a simple combination of vegetables that have a great flavor together. For different variations, many other vegetables could be substituted, including russet potatoes, green beans, zucchini, cauliflower, and bell pepper.

Can I make this Instant Pot vegetable soup ahead of time?

The soup can be made ahead of time and reheated in the microwave or on the stove when you’re ready to serve it. If you won’t be serving it all at once after cooking, you may want to skip the broccoli because it can get mushy if you need to reheat the soup. 

Can I make this soup on the stove?

For a stovetop version, add the avocado oil and onion to a large pot, and saute over medium heat until the onion is tender and translucent. Then add the remaining ingredients and simmer until the vegetables are tender.

Why make soup in the Instant Pot?

The advantage of cooking soup in a pressure cooker is that the soup will have a consistent result every time. When cooking on the stovetop, results can be inconsistent based on how high you turn up the burner from one batch to the next. In addition, the flavors of the soup meld nicely in the Instant Pot, and the soup cooks more quickly.

    I’ve now made this 3 times. Love the flavor. I hate to waste my veggies, so I double the amounts of veggies (minus the onion because it’s sauteed 1st). One recipe I cook now, and then I freeze the uncooked but chopped broc, cabbage, carrots, and celery for next time.

    We had this soup for dinner tonight! We were out of lemon pepper, but it didn’t matter, the soup was delicous! I loved the flavor, and so did my husband and son who had seconds. I called dibs on the last bit remaining. This is a keeper!
