Instant Pot Vegetable Soup
Vegetable soup has always been a soup I either LOVE or HATE.
Depending on how the soup is prepared and flavored, Veggie Soup is either incredibly full of flavor and hearty, or it is bland, watery, and boring.
I have a few secrets that help develop the most incredible Vegetable Soup, and it is prepared easily in the Instant Pot.
There is nothing fancy, no odd ingredients, and you can probably have all the ingredients needed right now to make this Vegetable Soup. My secret is to add in a bit of red wine, spices, and balsamic vinegar to add depth and flavor to an otherwise simple soup recipe.
It is a delicious plant-based recipe that makes a perfect meatless meal or healthy lunch!
- Vegetable Broth--I use my homemade vegetable broth. It is SO incredibly flavorful and easy to make. It really adds to the flavor of this simple soup. But feel free to use your favorite store-bought vegetable broth.
- Red Wine--A bit of wine really adds dimension to this recipe. I use a dry red wine such as a Merlot or Cabernet. If you don't drink, feel free to omit.
- Vegetables--This soup is full of vegetables. The base is built with onions and celery, but also features green beans, carrots, and potatoes are added to the soup. Feel free to add corn if desired.
- Diced Tomatoes--I love to use Italian seasoned diced tomatoes for extra flavor. If you use regular diced tomatoes, I would add additional garlic and oregano.
- Spices--Garlic, oregano, and a 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.
- 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. My husband NEVER complains if I omit them! HA!
- 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 really pop in your mouth. It is a secret addition that makes this soup out of this world!
How to Make Vegetable Soup in the Instant Pot
This soup is SUPER simple to make. The hardest part is chopping the veggies! It comes together with just a few steps and thanks to the Instant Pot, this Vegetable Soup develops really rich flavors in a very short amount of time.
The first step to preparing this soup is to saute the vegetables. Hit the saute function on the Instant Pot and let it heat up for a minute. Some models will read HOT, once heated, but it only takes a couple of minutes for the instant pot to heat up. Once heated, add in the olive oil, celery, and onions and saute until the onion is just beginning to soften, then add in the garlic and saute for about 30 seconds longer. You don't want to saute the garlic too long, or it will cause your garlic to burn and ruin the soup.
Next, add in the wine and scrape up any browned bits off the bottom of the inner pot--this helps prevent a burn warning. Let the wine simmer for just a minute and then turn off the Instant Pot. Add in the vegetable broth, vegetables, diced tomatoes, and seasonings.
Once the soup is prepared, place the lid on the Instant Pot and be sure your vent knob is sealed. Set cook time for 5 minutes.
After cook time has elapsed, allow pressure to release naturally for at least 15 minutes. This is really important. 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 yourself.
After pressure has been released, stir in greens and vinegar and just let the greens wilt--this takes just a minute or two. Then serve up this soup and be prepared to be blown away with how good this simple, economical vegetable soup tastes!
