What You’ll Need

Olive oil – for sauteing and adding a little bit of good fat to the soup.

Fresh veggies– An equal mix of diced onions, celery, and carrots adds a base of flavor to this

Garlic – Fresh garlic gives better results than dried garlic.

Diced tomatoes and tomato sauce – Adds bold body and richness to the soup.

Vegetable broth – Thins the tomato sauce base and adds more flavor than water would.

Frozen mixed vegetables – The bulk of the veggies for the soup are frozen mixed vegetables.Use any blend you like, but we prefer a blend with carrots, potatoes, green beans, corn, and lima beans. You get bonus points if it includes okra!

Seasonings– Bay leaves, Italian seasoning, and salt and pepper help enhance the flavors.

How to Make It

Saute the vegetables. Set your Instant Pot to SAUTE and add the olive oil. When the oil is hot, add in the onions, celery, and carrots. Cook the veggies for about 5 minutes or until they start to soften. Once they are softened, add in the garlic and cook for about 1 to 2 minutes or until the garlic becomes fragrant.

Add the remaining ingredients. Once the garlic smells good, add in the rest of the ingredients and give it a quick stir. Cancel SAUTE mode.

Turn up the pressure. Lock the lid of the Instant Pot on and set the valve to SEALING. Cook on high pressure for 15 minutes and allow the pressure to naturally release for 15 minutes once the timer beeps.

Release the pressure and serve. Once the 15 minutes of natural venting are done, turn the valve to VENTING to release the remaining pressure. Take the lids off and add in salt and pepper to taste. Serve it hot and enjoy.

What are the Best Vegetables to Put In Soup? 

We use frozen veggies for ease of use. They are all precut and mostly bite sized already so no extra prep work needed. We usually look for mix bags, but you can use individually packed veggies as well, just take some from each bag.

You can also use fresh veggies if you prefer. Just keep in mind, if you are in a hurry, you’ll need to clean, peel, and cut the veggies before adding them to the soup.

Some of our favorite veggies to use include:

  • carrots
  • potatoes
  • green beans
  • english peas
  • onions
  • celery
  • corn 
  • lima beans
  • okra
  • cauliflower
  • broccoli
  • mushrooms 
  • squash
  • zucchini

Mix and match the veggies you use to match your preferences.

Can I Add Meat to this Soup? 

You can definitely add meat to the soup if you want to for some extra protein. You can add leftover chicken or even shred rotisserie chicken in this. Or, if you have left over roast beef, you could add that in too.

Other options include browning up ground beef, turkey, or chicken and adding them in. You can season them with salt and pepper, garlic, and Italian seasonings to match the flavor in the soup, or you can try to mix it up a bit with other flavors.

How to Freeze It 

The key to freezing the soup is to let it cool completely first. Once it is cool, pour it into freezer safe container(s) or into freezer safe bags. You can store it in the freezer for up to 3 months. 

When you are ready to eat, let it defrost in the fridge. Then heat it on the stove or in the microwave.
