What is curry lentil soup?

curry lentil soup with sourdough bread and a spoon

Our curry lentil soup is an Indian-inspired recipe where the lentils are simmered in a rich tomato sauce enriched with spices and vegetables.

The recipe, however, unlike our lentil curry is not authentically Indian. We would describe it as a fusion between Indian and Italian cuisine.

To make it, we use simple ingredients and spices, similar to what we do in lentil vegetable soup.

We add veggies like potatoes and kale, but you can substitute those to match your preferences.

You’ll love this recipe because like our Italian lentil soup it’s easy to make in just over 30 minutes in one pot. It’s also packed with flavor and umami!

Curry lentil soup is wholesome, nourishing, fulfilling, and satisfying. You’ll feel great after eating this comforting meal!

Ingredients and substitutions for curry lentil soup

curry lentil soup ingredients

Quantities are in the recipe box at the bottom of the page.

Lentils

Use dry green lentils or dry brown lentils. Dry lentils don’t require soaking and cook in about 30 minutes.

To learn more about lentils, check out our guide on how to cook lentils.

Substitute canned lentils for dry ones if you don’t have 30 minutes for them to cook.

If you want a recipe with yellow or red lentils, check out our red lentils soup.

Flavor base

Make the flavor base with olive oil, onion, carrots, garlic, and ginger.

Substitute avocado oil for olive oil and leek for the onion.

Spices

Curry powder, ground turmeric, ground cumin, and red pepper flakes are essential to flavor the curry lentil soup.

If you are comfortable with using spices, you can always add more. For example, ground coriander and garam masala work well in this recipe.

We don’t use curry leaves for this recipe as they are not a staple in our pantry and are hard to find in western supermarkets.

If you like to use them, add them to the pot with the hot oil and let them shimmer for a minute before adding the onion and the rest of the ingredients.

Vegetables

We recommend adding diced potatoes and chopped kale to make the soup more flavorful, creamy, and nutritious.

Substitute sweet potatoes for potatoes and spinach or chard for kale.

Crushed tomatoes

Canned crushed tomatoes are our favorite.

Substitute diced tomatoes, fire-roasted tomatoes, or whole canned peeled tomatoes for crushed ones.

Vegetable broth

We prefer vegetable broth to chicken broth so that the recipe is vegetarian and everyone in our family can enjoy it.

Feel free to use your favorite broth.

Salt and black pepper

Sea salt or kosher salt and a few twists of black pepper.

Serve it with

You can serve curry lentil soup with a slice of toasted bread rubbed with garlic, a drizzle of extra virgin olive oil, a squeeze of lime juice or lemon juice, and some fresh cilantro or parsley.

Questions

Do I need to soak lentils overnight?

There is no need to soak lentils overnight before cooking them. However, we recommend rinsing the lentils under running water before boiling them.

Also, check for small stones that might hide between the lentils.

How long does it take for dry lentils to cook?

Dry lentils have different cooking times, depending on the types of lentils. For example, split red lentils usually cook in about 20 minutes, small brown Italian lentils cook in about 30, and larger brown or green lentils might take up to 45 minutes to soften.

The best way to check for doneness is to taste the lentils. They should be soft to the bite.

Storage

Make ahead: curry lentil soup is an excellent recipe for meal prep, as its flavor gets better a day after it’s cooked. Also, it keeps well for days.

Refrigerator: let the soup cool down, then transfer it to an airtight container and store it in the fridge for up to 4 days.

Freezer: this recipe is perfect for freezing. Let it cool down completely, transfer it to a freezer-friendly container, and freeze for up to 3 months.

Thaw: defrost curry lentil soup in the fridge over several hours or in the microwave with a thawing function.

Reheat: warm the soup in the microwave for a couple of minutes or in a saucepan. Add a dash of water if necessary.

    made today–6-4-24. Ran across this recipe when I googled ways to use up fresh Kale. I made a few substitutions and it was delicious. I used 1 can Cannellini beans instead of lentils, mushroom stock instead of vege broth, and a can of diced potatoes vs fresh. Everything else was per the recipe.

  2. 5 stars
    so glad i found this today, as the temps dropped and my work-from-home day gave me more time in the kitchen. super yummy, and yes, with some additions, but that’s what makes the recipe so good – it’s flexible! on the hunt for some crunchy bread (unless someone wants to bring me some naan?). thank you!

    1. Heidi, I’m happy you enjoyed the lentil soup – you are very right, naan bread is fantastic with this soup!!

      Thank you for taking the time to leave a comment here. Have a great rest of your day. Kindest,

    I’m trying to incorporate more fiber/eat more plant-based meals and a friend shared this recipe with me. I used a can of chickpeas in place of potato, a bell pepper instead of carrot, and 1/2 jar of Rao’s marinara in place of crushed tomatoes. With these changes in place, I had everything on hand and didn’t even have to go to the store.

    This recipe was so beyond delicious, comforting, satisfying and filling and now I have lunch for the week! Thank you for a fantastic recipe.

    1. Hi Scout, that’s great news, I’m very happy you enjoyed the soup 🎉

      Thank you very much for your feedback and for taking the time to leave a comment here. I’m very happy we could help a little with your lunch meal-prep 😉

      Have a great rest of your week. All the best,
