    Why You'll Love This Vegetable Soup

    There's just something about a bowl of vegetable soup that's so satisfying. Lightly seasoned with Italian herbs, broth-y, lightly tomato-y, and with all of the varying textures of veggies and potato.

    The Instant Pot cooks the vegetables perfectly, and this recipe is so easy it's almost a "dump-and-start" type of IP recipe. After a 2-minute saute to enhance the flavors of the herbs and garlic, all you do is add everything to the Instant Pot, lock on the lid, and pressure cook on high for 9 minutes.

    So easy! And the flavors and colors of the vegetables stay more vibrant with pressure cooking, as opposed to extended simmering required for stovetop soup. I hope you love how comforting and easy this soup is, 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's perfect in soup and much better than the mushy, over-cooked green beans you usually find in vegetable soup.
    • onion - any type of onion you have on hand is fine.
    • potatoes - I used gold potatoes and left the skins on. Red potatoes or russets are also great in vegetable soup. If you go with russet potatoes I recommend peeling them.
    • canned diced tomatoes - I always go for fire-roasted but regular diced tomatoes are fine, too.
    • broth - either store-bought or homemade vegetable broth.
    • fresh parsley - added after pressure cooking, it lends a lovely fresh green flavor and color to the soup.
    • 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. But don't fret if you don't have any. 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 ยพ tsp oregano, ยผ tsp each of marjoram, rosemary, and thyme, and a few dashes of sage.

    See recipe card below for quantities and full recipe.

    How To Make Instant Pot Vegetable Soup

    Once you gather your ingredients and chop the vegetables, prep is a breeze!

    two photos showing the stages of adding the soup ingredients to the Instant Pot.

    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, 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.

    Vegetable Soup FAQs

    What other vegetables can I add to vegetable soup?

    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.

    Can I cook it on the stovetop?

    Absolutely. See the stovetop instructions in the recipe card below.

    Is vegetable soup good for weight loss?

    Yes, it can be helpful. Whether you're trying to lose weight, increase fiber intake, or simply eat more vegetables, vegetable soup is a great option. It's low in calories and fat, high in fiber, and very satisfying.

    Top Tip

    Try to cut the potatoes into somewhat evenly-sized, 1- to 1 ยผ-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!

    • 6-quart instant pot - either 6- or 8-quart

    Ingredients 

    • 2 teaspoons oil, optional - or use a splash of the vegetable broth
    • 2 teaspoons Italian seasoning blend
    • 4 large cloves garlic, minced
    • 1 large onion, chopped
    • 3 ribs celery, chopped
    • 2 large carrots, peeled and cut into coins or half moons
    • 1 pound red or gold potatoes, cut into 1-inch pieces
    • ½ small head cabbage, outer leaves removed, cored and chopped - I like to cut into large bite-size pieces, about 2x2 inches.

    Prevent your screen from going dark

    Instructions
     

    • 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.
    • 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.

    For the stovetop:

    • 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.

    Notes

    Note 1 - if you don't have mushroom powder, it's fine to omit it. I usually keep some on hand for adding depth of flavor to soups, stews, chili, etc. Alternatively, you can add sliced mushrooms.
    Store leftover soup 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.
    Thaw overnight in the refrigerator and reheat on the stovetop or in a microwave. You can also use the Instant Pot's saute function to reheat soup.
