Middle Eastern Red Lentil and Chard Soup
A silky red lentil soup with wilted chard, cumin, and a bright squeeze of lemon—comforting, wholesome, and ready in under an hour.
It's a one-pot meal that comes together with pantry staples and a bunch of chard—no soaking, no blending required (though you can blend if you like it extra smooth). The soup is hearty enough for a weeknight dinner with warm flatbread, yet light enough for a starter or a lunchbox.
I love making a big batch on Sunday and reheating it through the week; the flavors deepen and the chard softens further. A drizzle of olive oil and a scattering of fresh parsley at the table make it feel special with almost no effort.
Ingredients
- 2 tablespoons olive oil
- 1 large onion, finely chopped
- 2 garlic cloves, minced
- 1 teaspoon ground cumin
- 1/2 teaspoon ground coriander
- 1/4 teaspoon ground cinnamon
- 1/4 teaspoon ground allspice
- 1 tablespoon tomato paste
- 1 cup red lentils, rinsed
- 6 cups vegetable stock
- 1 bunch (about 10 ounces) Swiss chard, stems separated and chopped, leaves sliced into ribbons
- 1 teaspoon salt, or to taste
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons fresh lemon juice, plus lemon wedges for serving
- 2 tablespoons chopped fresh flat-leaf parsley, for garnish
- Extra olive oil, for drizzling
Instructions
- Heat the olive oil in a large pot over medium heat. Add the onion and cook, stirring occasionally, until soft and translucent, about 6–8 minutes.
- Add the garlic, cumin, coriander, cinnamon, and allspice. Cook, stirring, for 1 minute until fragrant.
- Stir in the tomato paste and cook for another minute, then add the rinsed lentils and vegetable stock. Bring to a boil, then reduce the heat to a gentle simmer.
- Cover and simmer for 15 minutes, until the lentils are starting to break down.
- Add the chopped chard stems and simmer for 5 minutes. Then stir in the chard leaves, cover, and cook for another 5–7 minutes, until the leaves are wilted and tender.
- Season with salt and pepper. Stir in the lemon juice. If the soup seems too thick, add a splash more stock or water to reach your desired consistency.
- Ladle into bowls and garnish with parsley, a drizzle of olive oil, and lemon wedges on the side.
Cook’s tips
- Rinse the lentils well until the water runs clear to remove excess starch and any debris.
- For a smoother soup, blend about half of it with an immersion blender before adding the chard leaves, or blend fully after cooking.
- Add the lemon juice off the heat to preserve its bright flavor.
Substitutions
- Swiss chard can be replaced with spinach or kale; if using kale, add it with the chard stems and cook a few minutes longer.
- Vegetable stock can be swapped for water plus a bay leaf and an extra pinch of salt.
- Ground coriander can be omitted if you don't have it; the cumin and cinnamon are the key spices.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently on the stovetop, adding a splash of water or stock if needed.
Frequently asked questions
Can I use brown or green lentils instead of red?
Yes, but the texture will be different—brown or green lentils hold their shape and won't become silky. You'll need to increase the cooking time to about 30–35 minutes and add more liquid as needed.
Is this soup freezer-friendly?
Yes, it freezes well. Cool completely, then transfer to freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat on the stovetop, adding a little water if it's thick.
How can I make it more filling?
Serve it with warm flatbread, a scoop of cooked rice, or a dollop of yogurt. You can also add a can of chickpeas (drained and rinsed) in the last 10 minutes of cooking.
Can I make this soup in a slow cooker?
Yes. Sauté the onion and spices in a pan first, then transfer everything except the chard, lemon juice, and parsley to a slow cooker. Cook on low for 6 hours or high for 3 hours, adding the chard in the last 30 minutes. Stir in the lemon juice and parsley before serving.
