Dump & go! This Slow Cooker Vegetable Barley Soup recipe couldn’t be easier. Just throw everything in the crockpot and walk away! Healthy, delicious and packed with nutrients.

Slow Cooker Vegetable Barley Soup - Vegan Crockpot Recipe (1)

This slow cooker vegetable barley soup saved me on more than one occasion. I’ve lost count of how many times we’ve sat on the sidelines of my son’s soccer game on windy, blustery days. We barely noticed the weather while the game is on – cheering and living vicariously through every kick, pass and tackle will do that. But once we’re on our way home, all I can think of is a hot bowl of soup.

Truth be told, any of our favorite soup recipes would do. My son would vote for his favorite Pesto Turkey Tortellini Soup and my husband would opt for something like my Chicken and Rice Soup (Instant Pot).

But there is something really appealing about throwing all of the ingredients into a crockpot before the game and coming home to a piping hot, ALREADY COOKED batch of soup. Just serve and eat!

And as an extra bonus, this soup ranks high on the nutrition scale. It’s high in fiber and is plant based, not to mention packed with flavor thanks to the vegetables, herbs and spices.

💙 What's to love about vegetable barley soup:

▪️ SO EASY! After chopping the vegetables, just dump everything into your crockpot, along with some barley and broth. Set to LOW and let the slow cooker do its thing!
▪️ PLANT-BASED: This veggie-packed soup happens to be plant-based and vegan. It's packed with fiber (about 9 grams per servings) and nutrients.
▪️ VERSATILE: This soup is incredibly versatile. Switch up the veggies to suit your tastes or what you have on hand. Or swap the barley for another whole grain, such as brown rice or farro.

Ingredients for this vegetable barley soup recipe:

  • PEARL BARLEY: Pearl barley can be found in most well-stocked grocery stores or online. If using quick cooking barley, cook it separately, then add at the end. See the Frequently Asked Questions section below for further explanation.
  • BROTH: To control the sodium, I used low sodium vegetable broth in combination with water. I promise that the taste doesn’t suffer!
  • SWEET POTATO: I used a red-skinned (orange flesh) sweet potato, which is sometimes labeled as red-skinned yam at the grocery store. Peel and cut it into ¾-inch pieces. Hello, Vitamin C and beta carotene!
  • FROZEN GREEN BEANS: Why frozen? They don’t become overcooked in the crockpot.
  • OTHER VEGETABLES: A standard mirepoix combination – onion, carrots and celery.
  • SEASONING: Fresh garlic cloves, paprika, dried thyme, dried oregano, salt and pepper.
  • CANNED TOMATOES: Use one (14 ounce) can of petite diced tomatoes, including the liquid.

Tools you need:

SLOW COOKER: There are plenty of crockpots available in the stores and online. I like to use a digital programmable crockpot, like this one. The 8-quart capacity means you can make plenty of soup!

See recipe card below for full ingredients list & recipe directions.

Substitutions:

SWEET POTATO: Swap regular potatoes for the sweet potato. I like small yellow or red-skinned potatoes, but into quarters.
BARLEY: Try a different whole grain. Farro provides the same chewy texture as barley. Brown rice and quinoa are good gluten-free options.

How to make crockpot vegetable soup:

You have to love when recipe instructions are only three steps long! Making vegetable soup in a crockpot is truly one of the easiest recipes you’ll ever prepare. There is a bit of chopping, but from there it’s all hands-off prep time.

PREP THE VEGGIES: Start by chopping the onion, carrots, celery and sweet potato, and mincing the garlic.

COMBINE AND COOK: Dump everything (except for the parsley) into the slow cooker. Vegetables, canned tomatoes, barley, broth and seasoning. Set the slow cooker to LOW (a nice gentle simmer), cover and cook for 8 hours, or until the barley is tender.

GARNISH AND SERVE: Last steps…stir in the parsley, taste for seasoning (and adjust as needed) and serve it up!

What to serve with this vegetable barley soup recipe:

If I’m eating this soup for a light lunch, I’ll typically serve it alongside some whole grain crackers and hummus for an added boost of protein.

You could also add beans (still vegan) shredded rotisserie chicken (not vegan) to make a more hearty dinnertime meal for your family.

Soup is meant for dipping. Try a slice of Mushroom Rosemary Olive Oil Bread or Indian Spiced Chickpea Flatbread.

Frequently Asked Questions:

Can I use quick cooking barley in this soup?

Pearl barley take significantly longer to cook than quick-cooking barley, so one is not easily swapped for the other in most recipes. If you only have the quick cooking variety, cook it separately in a pot, drain it, then stir it in the finished soup.

Is barley gluten-free?

Unfortunately, it isn’t. Brown rice or quinoa would be good substitutes in this recipe. If you prefer to add gluten-free pasta, turn the slow cooker heat to HIGH in the last 30 minutes of cooking and stir in the pasta.

What kind of vegetables are in a vegetable barley soup?

The beauty of a crockpot vegetable soup like this is that you can throw almost any vegetable into the mix, substituting your favorites for any of the ingredients listed. Use what's already in your fridge or freezer - frozen vegetables are great for slow cooker soups - so that you don't have to make a separate trip to the store.

I used sweet potato, carrots, onion, frozen green beans, celery and canned tomatoes, along with a scoop of pearl barley. If some of those ingredients don’t float your boat, feel free to make substitutions, such as broccoli, green peas, cabbage or zucchini.

Can I freeze barley soup?

Nothing makes me happier than when soup freezes well. It means we can eat our fill, then have enough for future meals. This recipe makes a ton of soup (11 cups) and is ideal for freezing.

Allow the soup to cool, then transfer it to a freezer safe airtight container (or multiple container, depending on how much soup is leftover), such as these glass ones. Freeze the soup for up to 3 months.

When ready to eat, defrost the soup in the refrigerator, then gently reheat it on the stove or in the microwave.

    Made this today, it’s a rainy day in New Jersey and I needed some soup. I also added a handful of dried mixed mushrooms since I had those on hand. It just finished and it’s delicious. Thank you.

    We loved this! I added carrots and parsnips (because yum!). I may have cut too thin and my crockpot cooks quick but I did mine at 6 hours on low and it was perfect!

FAQs

Should barley be soaked before adding to soup? ›

Does barley help thicken soup? ›

What is pearled barley used for? ›

What happens if you don't rinse barley before cooking? ›

What is the difference between barley and pearl barley? ›

Hulled barley, considered a whole grain, has had just the indigestible outer husk removed. It's darker in color and has a little bit of a sheen. Pearled barley, also called pearl barley, is not a whole grain and isn't as nutritious. It has lost its outer husk and its bran layer, and it has been polished.

What is the ratio of barley to broth? ›

Is barley a carb or a protein? ›

A one-cup serving of cooked, pearled, barley provides 193 calories, most of which are carbohydrates. You'll consume 44.3 grams of carbohydrates in a single serving, 6 grams of fiber, and 0.4 grams of naturally-occurring sugar. The rest of the carbohydrates in barley are starch.

What if I put too much barley in my soup? ›

As barley is a starch the best you can do is dilute it, or thin it out a bit. You may need to add a fair bit of broth and more of your vegetal ingredients. Possibly to the point of doubling your recipe. It will depend on when you find the taste and texture to have gotten back to acceptable levels.

Can you overcook barley? ›

Overcooked barley will become mushy, while undercooked may have a thicker and chewier texture. You can make barley as a side dish, but you can also cook it into your food. Feel free to cook our pearled barley in your favorite soup or stew, but be mindful that it will absorb a lot of liquid.

First, is barley better for you than rice? Barley and brown rice both have their benefits. If you're avoiding gluten, then brown rice should be your go-to, because barley has gluten.

What happens when you soak barley? ›

Should barley be washed before soaking? ›

Tips for Preparing Barley Like all grains, before cooking barley, rinse it thoroughly under running water and then remove any dirt or debris that you may find. Soaking is the next important first step as the raw grain may contain substances that are difficult to digest or are toxic.
