Easy Instant Pot vegetable soup with barley! This vegan vegetable barley soup recipe is rich with flavor and quick enough for a weeknight meal.
Hiya, Rhubarbarians! Another weeknight dinner recipe for you today. Instant Pot vegetable soup! Loaded with mushrooms and barley and soooo much good stuff.
I’m getting quite a bit more out of my Instant Pot these days. I think I’m FINALLY comfortable enough to make most things without having to google it first. It took a while though. I remember when Instant Pot baked potatoes were amazing to me, LOL! I’m now learning how to build flavor (ahem.. amazingly flavorful Instant Pot cacciatore) and cook some pretty impressive dishes. BOOYAH!
Now that it’s spring, I want to try some lighter recipes. I’m going to be testing out some artichokes AND some strawberry cheesecake in it very soon. CHEESECAKE! How cool is that?
How to make a rich and flavorful vegetable barley soup
It’s not difficult to make a rich and flavorful plant based vegetable soup. The key: build flavor by sauteeing the veggies. This isn’t a dump and start IP recipe. You want to bring all that great flavor out of the veggies and then let everything simmer with the barley. First, brown the onions, then saute the rest of the veggies with the browned onions. Mmmm….
Using a mire poix (onion, carrot, and celery) will build the base of the flavor that you’re looking for. Adding earthy mushrooms will give you that umami flavor while the bay leaves will brighten up the soup just enough to keep it from being too heavy and flat.
I definitely suggest finding a vegetable broth that you love. My favorite is the Better Than Bouillon organic seasoned vegetable base. It’s a concentrated base that you add hot water to. Perfect for soups because you can add as much or as little of the concentrate as you want, so it doesn’t just taste like veggie stock.

Is vegetable barley soup healthy?
Yes! Vegetable barley soup is healthy! Obviously the veggies are very healthy. I don’t think there’s any question there. What you REALLY want to know is: is barley healthy?
This recipe (and most vegetable barley soup recipes) use pearl barley. Pearl barley is a processed grain, where the hull has been removed and the grain has been “polished” or “pearled.” Although pearl barley is not a whole grain, it does have quite a few nutritional benefits.
Pearl barley is low in calories and is also low on the glycemic index. It contains beta-glucan, which can normalize your body’s insulin response. It’s also loaded with dietary fiber, which means it takes longer to digest and will keep you full for a very long time.
As long you keep the sodium levels low, this soup is a very healthy meal!
Can I freeze it?
Yes, you can freeze vegetable soup with barley! The barley may not be *as* al-dente as it will be when it’s freshly made, but it will still be delicious.
Freeze for up to three months in a well sealed container. Thaw in the refrigerator and heat in a sauce pan. SO EASY!
How to make Instant Pot vegetable barley soup
First, get all of your vegetables chopped. Things can move pretty quickly once you add the veggies, so make sure those are prepped!
Brown those onions in the Instant Pot using the saute function. Add the rest of the veggies and saute those as well. Then add the liquid, the bay leaves, and the barley. Stir together and turn off the saute function.
Pressure cook on high pressure for 10 minutes. It takes about 15 minutes for the Instant Pot to fully come to pressure and about 3 minutes to manually release the pressure, so 28 minutes of closed lid time.
Serve with a bit of fresh parsley and enjoy!
Can I make this on the stove top?
You definitely can make this on the stove top! I suggest a dutch oven or soup pot over medium-high heat to saute all the veggies as stated in the instructions.
Once you add all the liquid and the barley, bring just to a boil, then reduce the heat to simmer and cover. Cook for about 30 minutes, or until the barley is cooked to your liking.
I’ve made this both on the stove top and in the Instant Pot, and I prefer the Instant Pot version. I feel like the flavors marry together more quickly when pressure cooked and it saves you about 10 minutes when all is said and done.

So glad I stumbled upon this recipe. Always looking for more recipes for the insta pot. Those mushrooms are a perfect way to bring in the umami flavor and texture while still keeping this vegan. It’s still chilly here and this soup is filling and warming too.

As much as I like a GOOD dump-and-start IP or slow cooker recipe, I’m glad to see you taking the realistic (and delicious) route here and building up your flavours first. With veggies and neutral grains like barley, it’s so much more delicious to really build a good flavour foundation. I think that there’s a lot of temptation to take the one-and-done approach to recipes, but the results are so often middling at best that I think it turns a lot of people off of using their Instant Pots. And hey, I’m all in favour of using more barley – it’s an underappreciated grain!

This comes at SUCH a great time! This week marks the week where I start to make my freezer meals to stash away for when baby comes. SO GLAD you can freeze this! This will offer up the cozy nourishment I know I’m going to need during that time. And it’s an excuse to lug out my Instant Pot. I love the thing, but I still feel like I just don’t use it as much as I should!
Jenni LeBaron says
Pearl barley is such a great way to make this soup super hearty and filling. I love a classic veggie soup and this one really does a nice job of encouraging the weather to stay a little drizzly right now so I can enjoy it a bit longer! Bonus that I can make it in the Instant Pot!

I don’t have an Instant Pot, but I do have a pressure cooker. Hubby LOVES barley soup. I will adapt this to make it work…and I know it will be a hit. He will be thrilled.
Julie Menghini says
That is one beautiful bowl of soup that I could eat every day! I’m getting my instant pot out a lot more these days. Making soup in it is the best since you can cook it without boiling the heck out of it and losing all that texture and flavor in longer cooking methods. I’m a barley lover too and I can’t wait to make this recipe!
