Ingredients for vegetable soup:
- Canola Oil: used to sauté the onion
- Vegetables: I use a blend of onion, carrot, celery, green beans, corn, spinach, and potatoes. Feel free to add in or leave out whatever veggies you want!
- Tomato Paste: adds richness and flavor depth.
- Garlic: use freshly minced garlic for the best flavor.
- Seasonings: Italian seasoning, salt, black pepper
- Broth: you can keep this soup vegetarian with vegetable broth or use chicken broth or chicken stock instead.
- Tomatoes: I use fire roasted diced tomatoes, but other flavors will work as well.
- Bay Leaf: this adds a subtle earthy flavor that heightens the other flavors in the soup.

Instant pot vegetable soup FAQs
You’ll set the timer in the instant pot for just 2 minutes! However, the soup isn’t actually cooking for just 2 minutes. The pot takes about 15 minutes to come to pressure. In that time, the veggies soften and the soup cooks!
Leftover vegetable soup will last in an airtight container in the fridge for 3-4 days. To reheat, warm on the stove, in the microwave, or on “SAUTE” in the instant pot.
Yes! This vegetable soup is incredibly freezer friendly. Simply let it cool to room temperature, then transfer it to a freezer safe container or freezer bag. Store it in the freezer for 4-6 months. To reheat, thaw overnight in the fridge or in a sink of cold water, then warm in the microwave or on the stove. You can also reheat it in the instant pot on “SAUTE” until warmed through.
Variations on this Instant Pot soup
- Add meat. You can add ground beef, ground turkey, or Italian sausage to this soup by sautéing the meat with the onion before you add the rest of the ingredients. You can also use up leftover already cooked meat like shredded chicken by just adding it with the broth.
- Use other veggies. This recipe is super customizable. Use whatever veggies you like!
- Add beans. You can add vegetarian protein to this soup by mixing in canned and drained cannellini beans, great northern beans, white beans, or even chickpeas.
- Spice it up. Give your soup a kick of heat by adding in red pepper flakes or cayenne pepper.
- Make it creamy. You can turn this into a creamy vegetable soup by adding a can of evaporated milk or by serving it with a splash of heavy cream.
You can serve this vegetable soup as a light vegetarian entree with a side of garlic herb dinner rolls, garlic bread, or breadsticks.
It also makes the perfect side dish next to grilled chicken, air fryer pork chops, or the protein of your choice!

Instant Pot Vegetable Soup
- 1 teaspoon canola oil
- 1 medium onion finely diced
- 1 tablespoon tomato paste
- 2 teaspoons minced garlic
- 2 teaspoons Italian seasoning
- 2 teaspoons salt
- 1/4 teaspoon black pepper
- 6 cups low sodium chicken or vegetable broth
- 1 lb potatoes chopped (about 3-4 medium)
- 3 large carrots peeled and chopped
- 2 ribs celery sliced
- 1 1/2 cups fired roasted diced tomatoes (or other flavor — 398ml/13oz)
- 1 cup fresh green beans cut in thirds
- ½ cup canned, frozen or fresh corn
- 1 bay leaf
- 1 cup finely chopped spinach
- Heat oil in Instant Pot on saute mode. Add onion, cook and stir until softened.
- Turn the Instant Pot off and add the tomato paste, garlic, Italian seasoning, salt and pepper. Stir and cook for 1 minute on the residual heat.
- Add chicken broth to the still hot pan, and scrape the bottom with a spoon to remove any left behind bits.
- Add potatoes, carrots, celery, tomatoes, green beans, corn, bay leaf and stir.
- Put the lid on, turn the valve to sealing, and select Manual or Pressure Cook for 2 minutes. It will take about 15 minutes to come to pressure and begin counting down.
- Once the cook time is over, let pressure release naturally for 8-10 minutes before opening the valve and removing the lid (this is to prevent the splatter that can come when pressure cooking soup).
- Stir in the spinach, adjust seasonings to taste (add 1 teaspoon sugar to balance tomato paste if needed) and serve.

I do lots of meal prep on the weekends and this soup is a go-to for lunches! It takes a sec to chop everything, but throwing it in and then waiting is amazing.
My trick for getting the pressure to rise faster is to boil water in my electric kettle while doing all of the chopping. Adding the hot water to the instant pot speeds up the process and doesn’t change the texture or flavor. I also opt for kale instead of spinach, since it holds up a bit better over a few days.
Thank you for the recipe!
