A hearty slow cooker beef barley soup will stick to your bones and keep you full all winter long. It’s packed full of vegetables, barley, and beef.

It’s been raining for two straight days here.
This does not make me happy. I have always wanted to be one of those people who don’t mind the rain, but sadly, I am not.
I now know I could never hack living in Washington. I would probably shrivel up and die. I need sunlight.
It’s only December 7th and I already miss the sunlight of summer. Blerg.

So, what’s better than soup for when you are feeling down?
Nothing, in my opinion.
Especially when it’s a thick and hearty stick to your bones type of soup. Luckily this slow cooker beef barley soup is just that!

Plus side, it’s also made in the slow cooker.
So when you’re in a sloth-like state, because it’s grey and rainy, you only need to exert a small amount of energy to throw everything in the cooker.
Then it’s back to being lazy! It’s the best.
Enjoy!!!

Slow Cooker Beef Barley Soup

Ingredients
- 2 pounds chuck roast, cut into bite size pieces
- 1 14 ounce can diced tomatoes
- 2/3 cup pearl barley
- 4 carrots, peeled and diced
- 3 sprigs of fresh thyme, leaves pulled off stem
- 1 large onion, diced
- 1 green pepper, cored and diced
- 2 teaspoons kosher salt
- 1 teaspoon fresh cracked pepper
- 6 cups beef stock, more if needed
Instructions
- Add all ingredients to a large 6-quart slow cooker, give a quick stir, and cook on low for 8-10 hours.
- Every few hours I like to give mine a stir and check the liquid level. If it looks as though there is not enough liquid you can add more stock or water.

HIGH for 8-10 hours? Not Low?
Hi Laura! Sorry about that! When I re-typed the recipe I must have made that mistake. I changed the directions 🙂
No apologies needed! Glad I checked. Making this today – looks great and is one of the only soups my husband will eat.
Can i substitute dried thyme instead of fresh?? And if so,
How much will i need??
Thank you!!
Hi Tiffany! Dried thyme will work just fine. I would add 1/2 teaspoon dried thyme in place of the fresh. If you’re not a fan of thyme you could always drop it down to 1/4 teaspoon. Hope this helps!
I made this today and it turned out great! I didn’t have enough beef stock so I had to sub chicken stock for some of the liquid, I wound up using 32oz beef and 24oz chicken and it was delicious and a perfect consistency. I also added a sprig of fresh rosemary. I will try it again using all beef stock, but either way it was great!
I could only find Qucker’s “Quick” pearled barley in my grocery store, does the fact that it is Quick cooking barley make any difference to this recipe in the slow cooker?
Hi Stephen! I apologize for taking so long to get back to you. I have never used quick barley but I’m assuming it cooks much faster than normal pearled barley. I worry it could cook up too fast and turn mushy. If you give it a try and it works out let me know!
What is this “Green pepper”? Is it bell pepper? Is it some hot pepper like jalapeno? Can you clarify, please? Thanks!
Yes! The green pepper I’m referring too is a green bell pepper. I’m going to clarify this in the directions as well. Thanks!
I made this and my husband and I didn’t care for it. I don’t know if it’s because of the canned tomatoes or the thyme but it left a flavor we didn’t like. I really wanted this to come out good because I love getting this soup from restaurants.
