Recipe Questions & Answers

Can I make this soup gluten-free?

Yes, simply replace the pearl barley with short-grain brown rice or quinoa. Both maintain the hearty texture while making it gluten-free. Always verify your vegetable broth is certified gluten-free as well.

What greens work best in this soup?

Collard greens hold up beautifully during simmering without becoming mushy. Swiss chard, kale, or even spinach work well too—just add delicate greens like spinach in the last 5 minutes to prevent overcooking.

How should I store leftovers?

Refrigerate in an airtight container for up to 5 days. The barley will continue absorbing liquid, so you may need to add more broth or water when reheating. Freeze for up to 3 months in portion-sized containers.

Can I use different types of lentils?

While red and brown lentils create a nice texture contrast, you can use all green lentils for a firmer bite. Avoid only using red lentils alone, as they'll break down completely and make the soup overly thick.

What can I serve with this soup?

Crusty whole-grain bread, garlic knots, or a simple side salad make excellent accompaniments. For a heartier meal, top with croutons or serve alongside a grilled cheese sandwich.

Do I need to soak the lentils or barley?

No soaking required. Red and brown lentils and pearl barley cook relatively quickly. Just rinse everything well before adding to remove any debris or dust.
