Ingredients

Here’s what you’ll need :

1 tablespoon oil (vegetable, canola, or olive)
1 lb beef stewing meat, cut into bite-sized cubes
1 small onion, finely diced
2 teaspoons minced garlic (about 2–3 cloves)
1 teaspoon salt (adjust later to taste)
1 teaspoon Italian seasoning (a blend of oregano, basil, thyme, etc.)
¼ teaspoon black pepper
3 large carrots, peeled and chopped
2 ribs celery, chopped
½ cup pearl or pot barley, rinsed under cold water
2 tablespoons tomato paste
2 bay leaves
4 cups low‑sodium beef broth
Fresh parsley (chopped), for serving

Yield: Approx. 2 quarts (about 4 cups per quart). One serving = 2 cups.

Step‑by‑Step: How to Make Slow Cooker Beef Barley Soup

1. Brown the beef

Heat a large pan over medium‑high heat. Add the tablespoon of oil, let it warm about 1 minute until shimmering. Working in batches (so the pieces don’t crowd and steam), brown the beef cubes on all sides. You want a browned crust, not boiled meat. Transfer browned beef to your 4–6 quart slow cooker.

2. Sauté onion & seasonings

In the same pan (don’t rinse; those browned bits add flavor), add the diced onion and cook over medium heat until translucent (about 3–4 minutes). The onion will pick up those flavorful browned bits. Stir in the garlic, salt, Italian seasoning, and black pepper; cook for another minute to toast the aromatics.

3. Combine into slow cooker

Add the sautéed onions & seasonings into the slow cooker over top of the beef. Then add the chopped carrots, chopped celery, rinsed barley, tomato paste, and the two bay leaves. Stir gently to combine.

4. Add the broth

Pour in the 4 cups of low‑sodium beef broth, stirring gently to make sure the tomato paste is well distributed.

5. Cook low and slow

Low setting: Cover and cook for 6–8 hours
High setting: Or, cook for 3–4 hours

Cook until the vegetables and barley are tender and the beef is fork‑tender. The soup should have a slightly thickened, stew-like consistency from the barley.

6. Finish & serve

Before serving, stir in chopped fresh parsley to brighten up the flavor. Taste and adjust seasonings: you may want a bit more salt or pepper. Remove bay leaves. Ladle into bowls and enjoy!

Helpful Tips

Don’t skip browning: That step introduces deep, umami flavors via the Maillard reaction.
Rinse the barley: This removes surface starch that could otherwise make the soup overly thick or gummy.
Layer gently in the slow cooker: Put meat first, then vegetables, then pour broth so you don’t dislodge the layered flavor.
Avoid overcooking barley: If left too long, barley can go mushy—so aim for the shorter side of cook times if your slow cooker runs hot.
Degrease if needed: If you see excess fat pooled on top after cooking, skim it off with a spoon or chilled paper towel.
Seasoning adjustments: Because of the residual salt in beef broth, season lightly early and adjust at the end.
Reduce liquid if too runny: If your soup seems thin, you can remove the lid for the final 30 minutes on high to let excess liquid evaporate.

Substitutions and Variations

Protein swap: Use diced lamb, cubed pork, or even chicken thighs (cook time may vary).
Grain alternative: Use farro or hulled barley for a chewier texture (note: cook times may shift).
Vegetable additions: Add diced potatoes, parsnip, turnip, green beans, or peas in the last hour.
Herb alternatives: Replace Italian seasoning with dried thyme, rosemary, or a bundle of fresh herbs (bouquet garni) for a more customized flavor profile.
Tomato twist: Use a can of diced tomatoes (14 oz) instead of tomato paste + broth, for a lighter, tangier version.
Spicy kick: Add a pinch of red pepper flakes, or a dash of hot sauce, especially at the end.
Vegetarian version: Omit beef; use vegetable broth and substitute mushrooms or lentils, though the flavor profile will differ.

Storage Instructions

Refrigerator: Store in an airtight container. It will keep well for 3–4 days.
Freezer: Let soup cool fully, then transfer into freezer‑safe containers or heavy freezer bags, leaving some headspace. Freeze for up to 3 months.
Reheating: Thaw overnight in refrigerator (if frozen). Reheat on stovetop over low‑medium heat, stirring occasionally. You may need to add a little extra broth or water, as barley continues absorbing liquid.
Avoid microwave overheating: The barley and vegetables can overcook; reheat gently until just warmed through.

Frequently Asked Questions About Slow Cooker Beef Barley Soup

Can I use quick‑cooking (instant) barley instead of pearl barley?
You can, but results vary. Quick or instant barley cooks much faster and may become mushy with long slow cooker times. If you use it, add it during the final 1–2 hours of cooking rather than at the start.

My soup is too thick — how can I thin it out?
Stir in extra beef broth or water, a half cup at a time, until you reach desired consistency. Reheat gently after adding.

It seems under‑seasoned — when should I add more salt or herbs?
It’s best to season gently early on, because the flavors concentrate during cooking. After it’s fully cooked, taste and adjust — add salt, pepper, or fresh herbs at the end.

Can I double or triple this recipe?
Yes — just use a larger slow cooker (at least 6‑8 quart) and adjust cook time if needed. Make sure not to overfill; keep ingredients below the “max fill” line.

Will the vegetables overcook or turn to mush?
With slow cooking, softer vegetables like carrots and celery tolerate long cooking. Barley is usually the limiting factor — if it becomes too soft, reduce cooking time or switch to a more resilient grain.
