Instant Pot Vegetable Soup FAQs
Yes, you can. I recommend using an immersion blender. Although a food processor is another option, immersion blenders tend to give a better result since you’re working with a lot of liquid and don’t want to miss any chunks.
You can substitute apple cider vinegar or lemon juice for a similar acidity.
No, it will likely be too full. Stick to one batch to avoid overflow.

- 3 Stalks celery, chopped
- 6 Cloves garlic, minced
- 1 Teaspoon salt, kosher
- 1/2 Teaspoon black pepper, ground
- 1 Tablespoon Italian seasoning

- 2 Cups frozen mixed vegetables

Instructions
- On your instant pot, press the ‘sauté’ button.
- When the ‘hot’ indicator light has illuminated, add olive oil. Next add in sweet onion, and diced celery.
- Sauté for 2 or 3 minutes. Once the onions have become fragrant and translucent, add minced garlic and sauté for an additional 30 seconds.
- Once the sweet onions and garlic are fragrant, add salt, black pepper, Italian seasoning, paprika, and Worcestershire sauce. Sauté the ingredients together for an additional 30 seconds.
- Add white wine vinegar to deglaze, making sure all the small bits are scraped up from the sides of the Instant Pot.
- Add vegetable broth, water, the diced tomatoes, potatoes, sweet potatoes, and frozen mixed vegetables. Stir with a wooden spoon to combine all the ingredients, ensuring nothing is sticking to the sides of the pot.
- Add a bay leaf on the top surface of the soup. Close the lid and ensure the valve is in the "sealing" position on the Instant Pot.
- Set your Instant Pot to "pressure cook" and set the time for 5 minutes. Allow the Instant Pot to naturally release for 10 minutes. After 10 minutes of natural release, move the valve to the “venting position” to release the remaining pressure.
- Once the pressure has been fully released, open the lid and carefully remove and discard the bay leaf from the top of the soup. Be careful, the soup's very hot! Press the ‘cancel’ button and ensure the Instant Pot is set to ‘off’.
- Serve immediately, garnished with parsley.
