We swooned over this Slow Cooker Indian Lentil Soup with coconut milk and spinach and this soup is vegan, gluten-free, and dairy-free. It’s also quite low in carbs; just use more spinach and fewer lentils if you want a version that’s even lower in carbs.

I know some of you are going to take one look this Slow Cooker Indian Lentil Soup and veto it because you think the Indian spices, the red lentils, or the spinach is just not going to appeal to you. But that would be truly sad, because the entire time we were making this easy slow cooker soup, Jake and I just couldn’t stop tasting it and remarking on how good it was!

Admittedly Jake is an Indian food lover, and I’m a fanatic for red lentils, but still we’re pretty picky about what we consider to be “blog-worthy” and this delicious soup more than made the cut. I loved it with a generous squeeze of lime.

The soup was adapted from a recipe for yellow split pea dal I saw in a fun little book called 50 Simple Soups for the Slow Cooker (affiliate link) but truthfully I changed it up quite a bit in my version. What I didn’t change is the fact that this delicious soup is vegan, making it a perfect choice for a plant-based dinner idea.

What ingredients do you need?

What kind of lentils are best for Indian Lentil Soup?

I highly recommend using red lentils for this soup! The red lentils will dissolve much more quickly, helping the slow get done sooner in the slow cooker. Red lentils also have a slightly sweeter flavor compared to green or brown lentils.

What size slow cooker did I use?

I used a 5-1/2-Quart Slow Cooker (affiliate link) for this recipe, but it could have been a little smaller.

Is Indian Lentil Soup low in carbs?

When I calculated the nutritional information for this recipe I realized that because there is a lot of low-carb spinach, vegetable broth, and coconut milk, this tasty soup only has 11.8 net carbs per serving. If you’d like to make a version that’s even lower in carbs than that, just use more spinach and fewer lentils and it will still be delicious!

How to Make Slow Cooker Indian Lentil Soup:

(Scroll down for complete recipe with nutritional information.)

  1. Heat olive oil, then cook the onions until they’re slightly brown.
  2. Add minced garlic, ground cumin, ground coriander, ground turmeric, garam masala, and ground cinnamon and cook 1-2 minutes more.
  3. Put the spiced onions in the slow cooker.
  4. These are the red lentils I love so much for soup. Pick them over and discard anyone discolored ones and rinse with cold water before you add them to the slow cooker.
  5. We used canned vegetable broth and added enough water to make 4 cups.
  6. Add the lentils and vegetable broth to the slow cooker with the onions and spices and cook on high for about 2 hours or on low for about 4 hours.
  7. After 2 hours, the ground turmeric had given the lentils a beautiful yellow color and they were starting to dissolve into the soup.
  8. Turn the slow cooker to low and add coconut milk and chopped spinach and cook about 30 minutes more.
  9. Season the soup generously with salt and fresh ground black pepper and serve hot.
  10. This soup is delicious with a squeeze of lime added at the table!

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
All types of lentils and split peas are approved for the original South Beach Diet, but serving size is limited. In a soup recipe like this with lots of other ingredients you can eat a moderate size serving for Phase One. Lentils may be high in carbs for other low-carb eating plans, but if you check the nutritional info for this recipe you’ll see it’s relatively low in net carbs and you can reduce the carbs even more by using fewer lentils and more spinach.
