Vegetable soup has always been a soup I either LOVE or HATE, depending on how the soup is prepared and flavored.
Today, I am sharing with you the ultimate recipe for Instant Pot Vegetable Soup that will guarantee your soup is incredibly full of flavor and hearty and never bland, watery, or boring.
Reasons to Love Instant Pot Vegetable Soup
- Layered Flavors. The secret to making the best version of Instant Pot Vegetable Soup is to layer flavors. Adding a bit of dry red wine, a variety of dried spices, and balsamic vinegar adds depth and flavor to an otherwise simple soup recipe.
- Comes Together Quickly. Thanks to the speed and convenience of Instant Pot, this veggie soup is ready in just over 30 minutes.
- Wholesome Recipe. Instant Pot Vegetable Soup is packed with vegetables, which in turn, fills this soup with nutrients and fiber.
- Affordable. This Instant Pot Vegetable Soup recipe calls for basic ingredients that you likely already have on hand.
- Versatile. Change out the veggies to suit your preference or what you have on hand.
Notes on Ingredients & Equipment
- Vegetable Broth: Use low-sodium store-bought or homemade vegetable broth.
- Red Wine: A bit of dry red wine adds dimension to this recipe. I recommend using a dry red wine such as a Merlot or Cabernet that is worth drinking for the best flavor. If you don't care to cook with alcohol use additional vegetable broth in place of the wine.
- Aromatics: The base of this vegetable soup is built with onions, celery, and garlic, which adds a classic, rich flavor to the soup.
- Spices: Oregano, salt, pepper, and bay leaf add flavor to this simple Veggie Soup. They all work together to bring out the flavors of the vegetables and complement the vegetable broth.
- Potatoes: You can use red potatoes, gold potatoes, or russet potatoes. I would recommend peeling russet potatoes, but the red and gold potatoes can be left unpeeled if desired.
- Green Beans: Use fresh or frozen trimmed green beans.
- Carrots: Use peeled, sliced carrots or frozen diced carrots.
- Italian-Seasoned Diced Tomatoes: Instead of using a can of plain diced tomatoes, look for one that has added oregano and garlic, which will lend additional flavor to the vegetable soup.
- Greens: I finish this soup with baby kale or spinach to add a hefty dose of nutrients. If you have super picky eaters, feel free to skip adding the greens.
- Balsamic Vinegar: This may sound like an odd addition, but trust me. By finishing this soup with a bit of balsamic vinegar, your palate is open and the flavors pop in your mouth. It is a secret addition that makes this soup out of this world!
- Instant Pot: If using a 3-quart pressure cooker, this recipe would need to be cut in half. It can be doubled in an 8 or 10-quart instant pot.
Substitutions/Modifications
- Regular Diced Tomatoes: If you use regular diced tomatoes, double the amount of garlic and oregano added to the soup, to amp the flavor up.
- Diced Frozen Veggies: Feel free to use up to 3 cups of frozen mixed vegetables in place of the green beans, carrots, potatoes, corn, etc.
- Oil-Free Option: If you prefer to cook without oil, use a bit of vegetable stock in place of the olive oil to saute the garlic and onions.
How to Make Vegetable Soup in the Instant Pot
While this is an incredibly simple recipe, if you are unfamiliar with cooking in an Instant Pot or the functions of your Instant Pot, be sure to start with How to Use an Instant Pot for the best results on this and future recipes. You will find the full recipe in detail in the recipe card below.
Step One: Saute Veggies. Rather than simply dumping the carrots, celery, onion, and garlic into the pressure cooker along with the other ingredients, taking a few minutes to saute the onions, celery, and carrots with the garlic will help develop the rich flavor in the soup.
Step Two: Deglaze. Whenever you saute ANYTHING in the instant pot, it is crucial to add thin liquid and scrape up any browned bits off the inner pot. This is called deglazing and will help to prevent a burn warning.
Step Three: Layer Ingredients. Add in the vegetable broth, potatoes, carrots, green beans, diced tomatoes, and seasonings, and stir gently to combine.
Step Four: Pressure Cook & Pressure Release. The cooking time for this vegetable soup is only 5 minutes. Any longer than that, your vegetable will turn to mush. After the cooking time has elapsed, allow pressure to release naturally for at least 15 minutes. If you try to release pressure before 15 minutes have passed, the hot liquid will spew out of your vent knob and make a mess, and potentially burn you.
Step Five: Finish Soup. After pressure has been released, stir in greens and vinegar and let the greens wilt. Note: For softer kale, add it to the soup before pressure cooking.
Serving Suggestions
Instant Pot Vegetable Soup is a fabulous, hearty, and healthy meal that is perfect to serve for dinner or lunch with homemade biscuits or whole wheat rolls and a side salad tossed with balsamic vinaigrette to compliment the balsamic added to the soup. Or serve with Whole Wheat Dutch Oven Bread and a Caesar Salad.
Storage Instructions
- Refrigerate: Allow the vegetable soup to cool slightly and then store it in an airtight container for up to 5 days in the refrigerator.
- Freeze: While you can freeze this soup, keep in mind that the texture of the vegetables will not be the same after thawing and reheating.

Delicious soup ! I substituted some veggies and added broccoli, leftover ham and chicken from Christmas dinner and an extra cup of water. It turned out great. 😊
Sounds great! Thanks for sharing.
Very good and it will be a go to for vegetable soup. I did add about heaping tablespoon of natural maple syrup to reduce acidy.
That's a great idea, Laurie! Thank you so much for sharing!
Excellent flavor! My wife absolutely loved it and it was easy to make. However, it took me a little over an hour to prepare from start to finish --slightly more than twice as long as the estimate. I will be making it again and again, regardless!
Hi Kerry! I am thrilled you enjoyed--and thank you for the feedback regarding timing.
Made this as written but added a can of cannellini beans and a small jar of marinara sauce. Delish!
