Why You'll Love It
There's just something about a bowl of vegetable soup that's so satisfying. Lightly seasoned with Italian herbs, it's broth-y, lightly tomato-y, and has all of the varying textures of veggies and potato.
What we really love about this particular recipe is that the Instant Pot cooks the vegetables perfectly! And it's so easy it's essentially a "dump-and-start" kind of Instant Pot recipe.
After briefly sauteing the herbs and garlic to enhance the flavors, you simply add everything else to the Instant Pot, lock on the lid, and pressure cook on high for 9 minutes.
The flavors and colors of the vegetables stay more vibrant with pressure cooking, as opposed to the extended simmering required for stovetop vegetable soup.
And with the cabbage and potatoes, I find it especially comforting and satisfying. I hope you love it, too!
Ingredient Notes
- cabbage - most vegetable soup recipes don't include cabbage, but in my opinion, it's the veggie that totally makes this soup! It cooks up perfectly tender, and we really prefer it over green beans, which are often in vegetable soup (and often over-cooked).
- onion - any variety
- potatoes - I used gold potatoes and left the skins on. Red potatoes or russets are also great in vegetable soup. If using russet potatoes, I recommend peeling them first.
- canned diced tomatoes - I used fire-roasted tomatoes but regular diced tomatoes are fine, too.
- broth - either store-bought or homemade vegetable broth
- fresh parsley - added after pressure cooking, it gives the soup a pop of color and lovely fresh flavor.
- mushroom powder - I'm always looking for easy ways to add umami to my plant-based recipes, and dried mushrooms/mushroom powder have become a staple in my pantry for that reason. If you don't have this ingredient, that's no problem. Just skip it!
- Italian seasoning - this is a blend of oregano, marjoram, rosemary, thyme, basil, and sage. If you don't have the blend on hand, make your own with about ¾ tsp oregano, ¼ tsp each of marjoram, rosemary, and thyme, and a few dashes of sage.

How To Make Instant Pot Vegetable Soup
Once you gather your ingredients and chop the vegetables, prep is a breeze!
1 - First, preheat the Instant Pot using the saute function. Set it for 3 minutes. After 3 minutes it will automatically turn off (or press cancel). Add the oil and give it a few seconds to get hot. Add Italian seasoning and garlic. Stir and let sit 1 minute.
2 - Add the remaining ingredients, and stir well. Lock on the Instant Pot lid, and set to sealing. Select manual/pressure cook, and cook at high pressure for 9 minutes. The Instant Pot will take about 15 minutes to come to pressure, then the timer will begin.
When the timer beeps and the 9 minutes are complete, carefully quick release the pressure by flipping the knob to the venting position.
Remove the lid, and stir in the fresh parsley and apple cider vinegar. Taste for seasoning and add salt, pepper, and soy sauce, if desired.
Variations
- Spicy - add diced jalapeno or other hot peppers, either to the pot or to individual servings. Crushed red pepper flakes and your favorite hot sauce are also quick and easy additions.
- Kid friendly - omit the black pepper and slightly reduce the Italian herbs. Serve with crumbled crackers and grilled cheese or vegan quesadillas on the side.
- Proteins - to make vegetable soup even more filling, add cooked tempeh, vegan ground beef, tofu chorizo, beans, or other vegan meats to the finished soup. Or bump up the amount of vegetable broth and add red lentils, TVP, or soy curls to the Instant Pot before cooking.

Equipment
I've included stovetop instructions in the recipe below, but otherwise you'll need an Instant Pot! I'm currently using this 8-quart model. It's also fantastic for making vegan yogurt, by the way.
A 6-quart Instant Pot should also be large enough for this volume of soup.
If you have a smaller pressure cooker you'll need to adjust the ingredient amounts accordingly.
How to Store and Freeze Vegetable Soup
This soup keeps in the refrigerator for up to 6 days.
To freeze vegetable soup, first allow it to cool completely. Transfer to a freezer-safe container leaving space at the top for the liquid to expand. Freeze for up to 1 month.
Let the soup thaw overnight in the refrigerator then reheat on the stovetop or in a microwave. You can also use the Instant Pot's saute function to reheat soup.
FAQs
For this Instant Pot recipe, you'll want to consider is whether the vegetable has a similar cook time to the other ingredients. A few options are frozen corn, peas, and green beans. For softer, quick-cooking vegetables like summer squash, split the pressure cooking into two sessions. Release the pressure after 5 or 6 minutes, add the squash, and resume pressure cooking for 2 to 3 minutes. Leafy greens like spinach and kale should be added after cooking. The residual heat of the soup is enough to soften the greens.
Absolutely. See the stovetop instructions in the recipe card below.
Yes, vegetable soup can be helpful for weight loss since it is low in calories and satisfying. Whether you're trying to lose weight, increase fiber intake, or simply eat more vegetables, homemade vegetable soup is a healthy option.
Top Tip
Cut the potatoes into somewhat evenly-sized, 1- to 1 ¼-inch pieces. This helps them cook evenly. If they're smaller, they may over-cook and split apart. Of course, it's just soup. An overly soft potato isn't the worst thing!
I finished our most recent batch of this soup for lunch today while typing up the recipe. Time to make another batch!

Instructions

- Add the remaining soup ingredients (not the Additions), and stir very well. Lock on the Instant Pot lid, and set the venting knob to sealing. Select manual or pressure cook, and cook at high pressure for 9 minutes. The Instant Pot will take about 15 minutes to come to pressure, then the 9-minute timer will begin.
- When the timer beeps and the 9 minutes are complete, carefully release the pressure by turning the venting knob to the venting position.
- Once the pin has dropped, carefully remove the lid. Stir in the fresh parsley and apple cider vinegar. Taste for seasoning and add salt, pepper, and soy sauce, if desired. Serve with salad and cornbread or other hearty bread.
Stovetop instructions:
- Preheat a large soup pot over medium-low heat. Saute the oil, Italian seasoning, and garlic for 1 to 2 minutes. Increase heat to medium and add the onion, celery, and carrots. Cook for 2 to 3 minutes.
- Add the remaining ingredients (not the Additions), and bring to boil. Reduce heat to low, cover, and simmer for 35-40 minutes. Adjust heat as needed to maintain a simmer. The soup is done when the vegetables and potatoes are tender. Stir in the parsley and vinegar. Taste for seasoning and add salt, pepper, and soy sauce, if desired.

Hi Lori! I am kinda obsessed with your recipes lately. I made your creamy Vegetable soup yesterday and made this cabbage vegetable soup today. Since I had so much soup I decided to add some of the creamy veg soup to this soup. Wow! Really good! I do love the cabbage veg soup by itself as well. I should have made some cornbread to eat with this delicious soup! TY Lori! All your recipes are soooo good!
Kris
Very flavorful! Feels very clean and light, and it was easy to make. I just love the Instant Pot! One comment from a family member was “best soup ever.” Thank you!

Wow, what great feedback! Thank you for sharing with us, Kris. Funny enough, I was just walking into the kitchen to make another batch of this soup when your comment came in. 😀
