This cozy Vegetable Barley Soup is hearty, flavorful, and naturally vegan since it’s made with rich vegetable broth. With tender pearl barley, potatoes, carrots, and peas, every spoonful is comforting and satisfying. You can also bulk it up with beans or lentils if you’d like even more plant-based protein.

This soup is the kind of meal that makes you feel cozy and cared for, while still being packed with good-for-you ingredients. The pearl barley adds a hearty, chewy texture, and all those colorful veggies bring fiber and fresh flavor to every bowl.

Ingredients Needed

Below are the ingredients you’ll need to make Vegetable Barley Soup. The full quantities can be found in the recipe card further down the post.

Olive oil: or avocado oil
Veggies: Yellow onion, Celery, Carrots, Yellow bell pepper, and Potatoes.
Garlic: Fresh is best, but jarred minced garlic works in a pinch
Sun-dried tomatoes: You can sub in a few tablespoons of tomato paste if needed
Oregano and thyme: I used dried herbs here, but if you’re using fresh herbs, double the amount for the same flavor
Kosher salt and black pepper: or your favorite seasoning salt blend
Marinara sauce: Use my homemade marinara for the best results, or your favorite brand to save time; plain tomato sauce works too
Frozen green peas: no need to thaw first; fresh peas can also be used
Pearl barley: rinsed well, not soaked
Vegetable broth: low-sodium is ideal; chicken broth works if you prefer
Parsley (optional): fresh and finely chopped for garnish

How to Make Vegetable Barley Soup

Here’s how to get perfect results every time:

Step 1: Heat olive oil in a large soup pot over medium heat. Add onion, celery, carrots, and bell pepper, cooking for about 5 minutes until softened.

✏️ This step builds the flavor foundation for your vegetable barley soup, so don’t rush it.

Step 2: Stir in diced potatoes, garlic, sun-dried tomatoes, oregano, thyme, salt, and pepper.

✏️ Seasoning early helps the potatoes and veggies soak up flavor as they cook.

Step 3: Continue to sauté for 2-3 minutes, stirring often so the vegetables and spices blend well.

Step 4: Mix in the frozen peas and pour in the marinara sauce, stirring until everything is coated.

Step 5: Stir in the rinsed pearl barley and vegetable broth. Bring to a boil, then reduce to a simmer for 35-45 minutes until the potatoes and barley are tender.

✏️ Barley soaks up liquid as it cooks, so check occasionally and add extra broth if needed.

Common Questions

Do I need to soak the barley before using it?

No! You don’t need to soak pearl barley. Just rinse it well, then add it directly to the soup; it will soften during simmering.

Can I use hulled barley instead of pearl barley?

Yes, but hulled barley takes longer to cook (sometimes 15-30 minutes extra). Adjust the simmering time accordingly and check for tenderness.

Is this soup gluten-free?

No. Barley contains gluten, so this recipe is not safe for people with celiac disease or gluten intolerance.

How to store leftovers?

Store leftovers in an airtight container for up to 4 days. You may freeze for up to 3 months. Thaw overnight in the fridge before reheating.

What to serve with this soup

I like serving this vegetable barley soup with a warm slice of my Whole Wheat Bread or soft Homemade Dinner Rolls. They’re perfect for dipping and make the meal feel extra homey.
