Instant Pot Barley Minestrone Soup

Posted: October 8, 2019 | by Sandra Valvassori

This colourful Instant Pot barley minestrone soup, hearty with beans, barley, and vegetables, is brimming with flavour and perfect for chilly nights.

To me, few things are as comforting as a minestrone soup. Full of vegetables that are good for you, it is nourishing and healthy yet robust enough not to leave you wanting more. Versions of this soup are everywhere and mine is ever-changing depending on what vegetables I have in the fridge. I have a stove-top version of minestrone soup that I make as often in the winter as I do in late summer when zucchinis and carrots are plentiful. The Instant Pot version I offer you today has a little more bite and substance with the addition of pearl barley making it a very satisfying, and downright delicious soup.

  • To Serve
  • You might wonder why you should bother cooking this soup in an Instant Pot when the cooking time is not much shorter than the stove-top version. Well, hear me out. In this post I explain that the instant pot does not really cook food in a shorter amount of time. It does, however, make the cooking process easier — chuck everything in to one pot, seal it, walk away. In less than an hour you have a delicious dinner on the table that practically cooked itself. To be honest, if I were making minestrone soup without the barley, I would likely just make it on the stove. When adding grains to the soup, however, the instant pot does a brilliant job of cooking everything together quickly and sealing in all the flavours.

    Ingredients for Instant Pot Barley Minestrone Soup 

    The ingredient list for this soup may seem a little daunting, but other than a little arduous vegetable chopping (good for the soul, I say) the rest comes from jars, cans, and tetra packs. Easy peasy. Below I address the main ingredients for this soup, but really, this is a soup where you can feel free to play with the ingredients as you see fit.

    • Vegetables: Minestrone is all about the vegetables. Here I’ve used the classics; onions, celery, carrots, and garlic. A lot of instant pot recipes will have you skip sautéing the vegetables. I like to make good use of the sauté mode on the instant pot and let the vegetables cook down to release all their wonderful flavours into the broth. As mentioned, the fun thing about this soup is its easy adaptability. Cubes of zucchini, sliced fennel, potatoes, and green beans would also be right at home in here. Be mindful, however, not to exceed 4-5 cups totals if using the instant pot.
    • Barley: Barley is an ancient grain that imparts a distinct nuttiness and wholesome flavour when cooked. It adds great texture and complexity to soups, but is also terrific as a base for salads, cereals, and grain bowls. Barley is known to be high in fibre and protein and to help lower cholesterol. Note that this recipe calls for pearl barley which cooks quicker, and is a little less chewy than hulled barley. Hulled barley has had less of the outer hull removed than pearled barley, however, fibre is still present in both forms of barley. If you prefer to use hulled barley, cook it separately as the longer cooking time it requires will turn the other vegetables to mush. This is a good article that explains the differences between hulled and pearled barley, if you’re interested.
    • Tomato Sauce: A good jarred marinara sauce adds incredible flavour to this soup – I like this one, or use your favourite. You can use a can of diced tomatoes, if that is what you prefer. If you do, consider increasing the amount of herbs and salt to enrich the flavour of the broth.
    • Broth: I like to use a mix of water and chicken broth for this soup. You can use all water or vegetable broth to keep the soup vegan. It all works since most of the flavour is coming from the veggies and marinara sauce. Store-bought broth is fine to use here, just be sure to always (always, always) but low-sodium.
    • Cannellini Beans: If you know me, you know I like to cook my beans from scratch. However, dried cannellini beans are hard to find so I simply go for the canned ones. Try and find a good-quality (preferably BPA-free) brand — I like this one. Here, I like to add them after the pressure has been released so they keep their shape nicely.
    • Spinach: It is common to use spinach in minestrone soups and it is what my family prefers. Sometimes, I will use kale which is a little heartier and does not wilt as much as spinach. Use whichever you prefer.
    • Pesto: Adding a few tablespoons of pesto to the minestrone soup will brighten up the flavours immediately. If you have a lot of basil make your own. If not, buy your favourite pre-made pesto. Alternatively, simply add a lot of chopped fresh basil before serving.
    • Parmesan cheese: A must to sprinkle over the finished soup. And if possible, toss a piece of the rind into the pot. It adds an incredible deep-flavour. If vegan, omit the parmesan and add 1 tablespoon nutritional yeast.

    To Serve

    To increase the depth of flavour in the finished soup, add a dollop of store-bought pesto. Alternatively, chop and/or smash a good amount of fresh basil and stir that in. A drizzle of good olive oil, and generous sprinkles of parmesan will also add a lovely deep and rich note to this hearty soup.

    I try not to always serve this barley minestrone soup with toasted crusty bread on the side. Haven’t succeeded, though often a green salad also makes an appearance. Enjoy!

    Instant Pot Barley Minestrone Soup

    Author: Sandra Valvassori
    The barley will soak up a lot of the broth. If you prefer it more brothy, add 2 cups of water or broth after it has pressure cooked.

    Instant Pot barley minestrone soup

    Ingredients  

    • 2 Tablespoons extra virgin olive oil
    • 1 medium onion diced
    • 4-5 carrots cut into 1/4-inch coins
    • 4-5 celery stalks diced
    • 4 medium garlic cloves minced
    • 3/4 cup pearl barley rinsed
    • 1 24- ounce 680 grams jar marinara sauce (or use a 28-ounce can of whole tomatoes)
    • 4 cups chicken broth or vegetable broth
    • 2 cups water
    • 1 teaspoon crushed red chile flakes more to taste
    • 2 bay leaves
    • 1 teaspoon each kosher salt and freshly ground pepper
    • 1 3-inch piece of Parmesan rind, (optional)
    • To finish:
    • 4 cups baby spinach
    • 1 14- ounce can cannellini beans or other white bean, drained and rinsed well
    • 2 Tablespoons homemade or store-bought pesto optional
    • Optional toppings:
    • parmesan cheese chopped fresh parsley, chopped fresh basil

    Instructions 

    • Set the Sauté function button to high and heat the olive oil for 1 minute. Add the onion, carrots, celery and garlic. Cook, stirring occasionally, until softened but not browned, about 4-5 minutes.
    • Add the barley, marinara sauce, chicken broth, water, chile flakes, bay leaves, salt and pepper, and parmesan rind, if using.
    • Secure the lid and set the Pressure Release to Sealing. Press Cancel to stop the Sauté function. Select Pressure cook or Manual setting; adjust pressure to high and set time for 18 minutes. When finished cooking, quick-release pressure and open the lid. Remove the bay leaves. Stir in cannellini beans, spinach and pesto, if using. Let warm for about 2 minutes or until spinach is wilted. Taste and add more salt and pepper, if necessary.
    • Serve immediately, garnished with grated Parmesan and chopped parsley and basil, if desired.

    Notes

    For this recipe I use a 6-quart Instant Pot.
    To freeze: Let the soup cool completely and then freeze individual portions in freezer bags or glass containers. Thaw in the refrigerator and warm gently in a pot adding a bit more liquid if necessary.

      This is a wonderful recipe. The result is delicious! My husband remarked that this is the best minestrone he’s ever had – high marks from someone who has been a chef, and has excellent cooking and tasting standards.

      I made it with hulled barley, which I pressure cooked while preparing the other ingredients (5 cups water to 1 cup barley at high pressure for 18 minutes – perfect). I poured it into a bowl and set it aside while cooking everything else. I strained the barley liquids right at the end, before adding into the cooked veggies.

      Since I did not cook the barley together I only put the 4 cups broth in with the veggies and excluded the 2 cups water.

      The pesto is a wonderful finish. I recommend it though I think this soup would be great without it.

      Note: I used a regular pressure cooker, not instant pot. Sauté setting for onions etc. is medium-high. Then once all the veggies were in, lid on, I brought to pressure on high and when steam began escaping, I reduced heat to medium-medium high and cooked the 18 minutes.

      It’s a new family favorite and will be made again!

        So happy you loved this soup! It is hands down one of favourite soups especially during the winter. Thank you so much for all your feedback – I enjoyed reading all the details on the tweaks you made :))

      Such a wonderful recipe! I’ve made this soup 4 times and it gets better every time. My family loves it, too. ❤️ This one is a keeper!

      The barley really makes this such a hearty soup. I’ve made it with the suggested marinara sauce and another time with canned whole tomatoes and agree that the jar sauce (or homemade/time permitting) gives the soup more depth of flavor. The optional pesto is a must–yummy!

      The recipe is fabulous as is, but depending on what I have on hand, I’ve used chopped leeks instead of onion and I’ve thrown in other veggies after the 18 minutes in the Instant Pot–baby kale or swiss chard instead of spinach, and a wee bit of cauliflower and fresh cooked green beans with success.

      Thank you so much for this recipe and the scrumptious photos!

      Would it be easy to make on the stove/in a regular pot?

      Reply
      • Sandra Valvassori

        Yes, absolutely! The only advantage to making the soup in the Instant Pot is that the barley will cook faster. When making it on the stovetop you can follow the same instructions but you might need to a bit more broth, or water, as it cooks. Just keep an eye on it and add as needed. Hope you give it a try and let us know how it goes 🙂

      This is hands down my all-time favorite soup. I’ve made it so many times that I can remember it by memory! I omit the barley, but add in 3 or 4 things of zucchini and some cabbage as well. Super delicious, super easy, super hearty!

        Yay! This makes me so happy!! I love that you replace the barley with zucchini and cabbage – sounds delish! Thank you so much for writing and sharing, I really appreciate it :))

      This soup is soooooo good! I made a big batch hoping to freeze some but everyone had seconds and there was nothing left 🙂
      I made it on the stovetop in a LeCreuset because I don’t have an Instant Pot. I used farro instead of barley, threw in some cauliflower and handfuls of fresh herbs from the garden (chives, basil, thyme, oregano). I love how versatile it is! Thank you, Sandra!
