Ingredient Notes

Here are the ingredients needed to make this flavorful soup, plus substitution ideas for your perfect curry lentil soup.

  • Lentils – These are the main protein source in this curry soup. You can use either brown or green lentils in the recipe. If using green lentils, you’ll need to add a few minutes of cooking time, as noted in the recipe card below.
  • Potatoes. Use waxy potatoes such as red, white, or Yukon gold, as they hold their shape nicely when simmered.
  • Mirepoix. The usual mix of onion, carrot, and celery makes a great flavor base and adds color and texture.
  • Garlic. If you don’t have fresh garlic on hand, substitute with 1 teaspoon garlic powder.
  • Tomatoes. Use canned for convenience or fresh if roma tomatoes are in season.
  • Tomato Paste. For even more curry flavor, substitute the tomato paste with red curry paste.
  • Greens: Use whatever greens you like—spinach, rainbow chard, beet greens, or kale. This time around, I used a packaged baby kale and spinach mix, but I’ve also used julienned full-grown kale with great results.
  • Spices & Herbs: The spice blend is a mix of curry, cumin, and a couple of bay leaves. If you like a little heat, add a pinch of red pepper flakes. For serving, cilantro adds a nice finishing touch and added flavor.

How To Make Curry Lentil Soup

With just a few simple adjustments, curry lentil soup can be made on the stovetop, in a slow cooker, or in an Instant Pot.

The stovetop and Instant Pot both take about the same amount of time, about 40 min. The slow cooker will take the longest, letting you set it and go about your day.

Here’s a quick look at your options:

  • Stovetop: Using a large pot, you’ll simply saute the onion, carrots, and celery. Add the spices and tomato paste and stir until fragrant. Stir in the remaining ingredients, except the greens, and simmer for about 30 minutes. Towards the end of cooking, add in the greens and enjoy!
  • Instant Pot: Add the ingredients, except the greens, to your pressure cooker bowl. Place the lid on the Instant Pot and set the release valve to the SEALED position. Press the MANUAL button and set the timer to 15 minutes. Once finished, set the valve to quick release or let it release pressure on its own (it takes about 20 minutes). Remove the lid and stir in the greens.
  • Slow Cooker: The set it and forget it method. Simply add the ingredients, except the greens, to the crock pot bowl. Cover with lid and set on HIGH for 3 – 4 hours or LOW for 6 – 8 hours. Add greens, let them wilt, and enjoy!

How To Store + Reheat

  • Refrigerator: Leftovers will keep for 5 – 6 days in the refrigerator, stored in a covered container.
  • Freezer: This soup is freezer-friendly and freezes well for up to 2 – 3 months. To freeze, let cool completely and store in freezer-safe containers (affiliate link), leaving 1/2 inch head space for expansion. Let thaw before reheating. You can also freeze larger portions in large ziplock bags or containers.
  • Reheat: Simply re-warm on the stovetop over low heat until warmed through. Alternately, reheat in the microwave using 30-second intervals, stirring after each, until warm. It makes a great meal prep for the week with homemade Naan on the side for soaking up the juices.

  • Pair with homemade vegan naan for dipping and swiping.

  • In large stock pot, heat water/olive oil over medium heat. Add carrots, celery and onions, saute for 5 minutes. Add the curry/tomato paste and garlic, stir to combine and cook for 3 minutes. Add the curry, cumin and red pepper, mix to combine and cook for 1 more minute.

Press the MANUAL button and set the timer at 10 minutes. Once finished, set valve to quick release or let it release pressure on it’s own (takes about 20 minutes). Remove lid, stir in the greens. Remove bay leaves before serving.

Slow Cooker: Add the ingredients, except the greens and water/oil, to the bowl of your crock pot. Cover with lid. Set on HIGH for 3 – 4 hours or LOW for 6 – 8 hours. Add greens, let them wilt. Remove bay leaves and enjoy!

Serve with homemade vegan naan or artisan bread. Add a squeeze of lemon juice for a touch of brightness and chopped fresh cilantro for extra flavor!

Serves 6

Store: Leftovers will keep in the refrigerator for 4 – 5 days. store covered. To keep longer, store in the freezer in freezer safe containers for 2 – 3 months.


Use any dark leafy greens you like….spinach, kale, swiss chard, broccoli raab greens, beet greens ect. Just be sure to julienne your greens if they are large leafy ones. If using full grown greens, add them about 10 minutes before soup is done as they take longer to wilt.

If using green lentils, they tend to take a little longer to cook, add another 5 – 10 minutes on the stovetop and 2 minutes in the Instant Pot.

Add a handful of raisins or currants for some sweetness at the end of cooking. Or, you may rather add some to the top of your individual servings. It’s highly recommended adding a light touch of sweetness with the curry flavor!

  1. Thank you for this recipe. Made this tonight. It was delicious.

  2. This is a wonderful, delicious recipe that is adaptable to whatever vegetables you have on hand. (I use cauliflower and green beans and just a small potato). The only addition i made which i think you can’t really leave out is unsweetened coconut milk. Not a full can, but maybe half. It adds depth to the flavor. Everyone i’ve made this for asks for the recipe, its a real crowd pleaser!

  3. Delicious! I added some extra veggies and used red lentils for this recipe 😋

  4. I loved this recipe. I used one large sweet potato (I really do not like putting potatoes in my soups) and added a can of corn niblets. I love lentils. I would definitely make this soup again!
