Ingredients (Serves 4)
- 1 tablespoon olive oil (15 ml)
- 1 medium yellow onion, diced (150 g)
- 2 medium carrots, diced (200 g)
- 2 celery stalks, diced (100 g)
- 3 garlic cloves, minced (9 g)
- 1 1/2 cups dried green split peas, rinsed (300 g)
- 1/2 cup pearl barley, rinsed (100 g)
- 2 medium potatoes, peeled or unpeeled and diced (450 g)
- 8 cups vegetable broth (1.9 liters)
- 1 teaspoon dried thyme (1 g)
- 1 bay leaf
- 1 teaspoon fine salt, plus more to taste (6 g)
- 1/2 teaspoon black pepper (1 g)
Step-by-Step Instructions
1. Rinse the Split Peas and Barley
Place the split peas and pearl barley in a fine mesh strainer. Rinse them under cool water until the water looks clearer. Pick out any small bits that do not belong. This quick step keeps the soup clean-tasting and helps the grains cook evenly.
2. Sauté the Vegetables
Warm the olive oil in a large soup pot over medium heat. Add the onion, carrots, and celery. Cook for 6 to 8 minutes, stirring often, until the onion turns glossy and the carrots start to soften at the edges.
Add the garlic and cook for 30 to 60 seconds. Stop when your kitchen smells savory and garlicky. Do not let the garlic brown too much, or it can taste bitter.
3. Add the Split Peas, Barley, Potatoes, Broth, and Herbs
Stir in the rinsed split peas, rinsed barley, diced potatoes, vegetable broth, thyme, bay leaf, salt, and black pepper. Scrape the bottom of the pot with a spoon so all the sweet browned bits from the vegetables mix into the broth.
4. Simmer Until Thick and Tender
Bring the soup to a gentle boil, then lower the heat. Cover the pot with the lid slightly cracked. Simmer for 55 to 70 minutes, stirring every 10 to 15 minutes so the peas and barley do not stick to the bottom.
The soup is ready when the split peas break down into a creamy texture, the barley tastes tender but chewy, and the potatoes crush easily with a spoon. The broth should look thick, golden green, and hearty.
5. Adjust the Texture and Seasoning
Remove the bay leaf. If the soup looks too thick, stir in a splash of broth or water until it reaches your preferred texture. If you want it creamier, mash a few potatoes against the side of the pot and stir them back in.
Taste the soup. Add more salt and black pepper if needed. Let it rest for 5 minutes before serving so the barley settles and the flavors deepen.
Expert Troubleshooting & FAQs
Why are my split peas still firm?
Old split peas can take longer to soften. Keep simmering and add more broth or water as needed. Avoid adding acidic ingredients, like lemon juice or vinegar, before the peas are tender because acid can slow softening.
Why is my soup too thick?
Split peas and barley both absorb liquid as they cook. Stir in extra vegetable broth or water, 1/2 cup (120 ml) at a time, until the soup loosens. It will thicken more as it cools.
Can I make this soup ahead of time?
Yes. This soup tastes even better the next day. Store it in the refrigerator for up to 4 days. Reheat it gently on the stove and add a splash of water or broth to bring back the original texture.
Can I freeze split pea barley vegetable soup?
Yes. Cool the soup completely, then freeze it in airtight containers for up to 3 months. Leave a little space at the top because the soup expands as it freezes.
Can I use quick barley instead of pearl barley?
Yes, but add quick barley during the last 15 to 20 minutes of cooking. If you add it too early, it can turn very soft and lose its chewy texture.
