Lentil Soup With Swiss Chard

This post may contain affiliate links. As an Amazon Associate, I earn from qualifying purchases. Please read my disclosure.

This warming lentil and swiss chard soup comes together in one pot in just 45 minutes with red lentils, curry spices, and a cooling yogurt swirl. I make it when I want something filling that packs real flavor, and the bold tangy balance keeps everyone coming back for more. It freezes well too, so I always have a batch ready for busy weeknights.

I created this soup on an especially cold week when I needed comfort food but wanted something that felt light and healthy at the same time. I had picked up a bunch of swiss chard at the farmers market without a clear plan, and when I saw the vibrant green leaves sitting in my fridge, I knew I wanted to pair them with something hearty and filling.

The solution came together quickly! I combined red lentils with curry powder, cayenne, and chickpeas for protein, then stirred in the chard right at the end so it wilted into the broth without losing its color. The lime and yogurt add the perfect cooling contrast to the aromatic spices, and the whole pot simmers in about 30 minutes with minimal effort.

This soup has become a regular in my meal rotation because it works for so many situations. I make it for weeknight dinners when I need something fast, I pack it for lunches throughout the week, and I’ve even served it to friends who were surprised that something this flavorful could come together so easily. My kids eat it without complaint, especially when I tone down the cayenne, and my husband always goes back for seconds.

🥘 Ingredients

My recipe has minimal prep, and just needs a handful of simple ingredients! This is what I use:

Olive Oil: I use extra virgin olive oil to sauté the aromatics. It adds flavor and helps the spices bloom. Avocado oil or coconut oil also work well here.

Red Onion: I use red onion for its slightly sweet flavor. Yellow onion works just as well.

Garlic: I use fresh garlic cloves, minced. Garlic powder doesn’t give the same depth of flavor.

Jalapeño: I use jalapeño for heat. I remove the seeds for less spice or leave them in for more.

Curry Powder: I use curry powder for depth and complexity. It’s what gives this soup its Indian-inspired flavor.

Cayenne Pepper: I use cayenne to add a “spicy” heat. I adjust the amount based on who I’m serving, and will often omit this when I’m making this for sensitive palates (like my kids!).

Vegetable Broth: I use vegetable broth as the base. Chicken broth works too if you’re not keeping this vegetarian.

Swiss Chard: I use swiss chard for its earthy flavor, fiber, and nutrition. I remove the tough stalks before chopping the leaves.

Red Lentils: I use dried red lentils because they cook quickly and break down to thicken the soup naturally. I don’t need to soak them first.

Chickpeas: I use canned chickpeas, rinsed and drained. They add protein and make the soup more filling.

Salt: I use salt to bring out all the flavors. I always taste and add more at the end if needed.

Greek Yogurt: I use thick Greek yogurt, slightly thinned with water. It adds cooling creaminess and balances the spice.

Lime: I use fresh lime wedges for brightness. Lemon works in a pinch.

Substitutions

Swiss Chard Substitute: I can use kale, spinach, or collard greens (1 bunch, about 1 pound) as a 1:1 replacement.

Red Lentils Substitute: I can swap in brown or green lentils (2 cups), but they take longer to cook, about 35-40 minutes instead of 20.

Chickpeas Substitute: I will use white beans if I don’t have chickpeas (15 oz can, rinsed and drained) as a 1:1 replacement.

Greek Yogurt Substitute: I recommend using coconut yogurt or cashew cream (6 tablespoons thinned with 2 tablespoons water) for a dairy-free version.

🔪 How To Make

Here’s how I make this spicy lentil soup with swiss chard step by step.

Sauté Aromatics: I heat oil in a large, heavy saucepan over medium heat. I add the onion, garlic, and jalapeño and cook, stirring frequently, until the onion is lightly golden, about 5 minutes. Then I stir in the curry powder, salt, and cayenne pepper.

Add Broth, Chard, Lentils, Chickpeas: I add 4 cups broth and the lentils, chickpeas, and swiss chard. I increase the heat and bring everything to a boil, stirring until the chard is wilted.

Simmer: I reduce the heat to low, cover, and simmer for 20 minutes, stirring occasionally, until the chickpeas are tender and the lentils have broken down.

Blend and Serve: I remove the pot from heat. I use a hand blender to puree the soup until it’s mostly creamy. I divide the soup among bowls, drizzle about 1 tablespoon of the thinned yogurt over each serving, and garnish with a few slices of jalapeño if I’m using them and a lime wedge.

📖 Variations

This swiss chard lentil soup is easy to customize based on what I have on hand or who I’m serving! Here are my favorite ways to switch it up:

Mild Version: I omit the jalapeño and reduce the cayenne to just a pinch for a milder soup that my kids enjoy more.

Tomato Version: I stir in 1 cup of crushed tomatoes with the broth for a richer, slightly tangy base.

Extra Vegetables: I add 1 diced carrot and 1 diced zucchini with the onions for more vegetables and texture.

Coconut Version: I replace 1 cup of the broth with coconut milk for a creamier, slightly sweet variation.

🍽 Serving Suggestions

I serve this soup with toasted whole wheat pita bread, warm naan, or my vegan flatbread for scooping. My almond flour tortillas are also a great side for a gluten-free option. A side of cucumber tomato salad also adds freshness and crunch that balances the hearty soup.

🧊 Storage Directions

Storing: I store the soup in an airtight container in the fridge for up to 4 days. I keep the yogurt topping separate and add it when I reheat individual portions.

Freezing: I freeze the soup in individual portions for up to 3 months. I don’t add the yogurt before freezing – I recommend adding that fresh when you’re ready to serve. I thaw the soup in the fridge overnight and reheat on the stove.

Reheating: I reheat the soup in a saucepan over medium heat, adding a splash of broth or water to thin it out since it thickens as it sits. I can also reheat individual portions in the microwave for 2-3 minutes.
