How to Make Vegan Curry Lentil Soup

Aside from its wonderful aroma and cozy flavors, this vegan curry soup is really easy to make. It only takes 30 minutes to put together – and that time is mostly dedicated to pulling as much flavors out of ingredients as possible. The rest of the time is hands-off simmering.

I like to slowly sauté the onions until they are golden brown and then layer in the other flavors one at a time. As one of my favorite kitchen tricks, I sauté the tomato paste until it’s dark red and richly flavorful. This is combined with lightly toasted curry powder for a richly flavorful broth that really makes this soup stand out.  

What Kind of Lentils Are Best for Soup?

If you’re new to cooking with lentils, here’s a little primer.

There are several different kinds of lentils – red, green, brown and black. They are all easy to find to find at the grocery store. For this soup, I recommend cooking with green or brown lentils. Both types take about 40 minutes to soften, but even when soft they retain their small, disc-like shapes.

Red lentils, by contract, lose their shape and can become mushy. That texture is perfect for recipes like my Spicy Red Lentils recipe, but they’re not the best opt for a broth-based soup.

Do You Have to Soak Lentils?

Nope! Lentils are a great vegan ingredient to use when you want to put a quick dinner on the table. Unlike dried beans and peas, lentils do not have to be soaked before cooking. You just need to rinse them and check them for debris (which is sometimes left over from harvesting).

Are Lentils Good for You?

They are! Lentils are high in protein and fiber. They’re also a good source of B vitamins, magnesium, zinc and potassium. And they’re known to be high in anti-oxidants.

Not only are lentils good for you, but they’re also good for the planet. Lentils use less water than other dietary protein sources. They also supply the soil with vitals nutrients.

How to Cook with Curry

Curry is one of my favorite flavors to cook with, but curry can be complicated. There is Indian curry, Thai curry and Japanese curry. Wet curries and dry curries. Some are mild, while others are spicy. If you want to learn all about curry, then be sure to check out my What is Curry? post.

What Is in Yellow Curry Powder?

For this recipe, I use an Indian yellow curry powder. It’s mild, featuring turmeric, cumin, coriander and fenugreek. To draw out as much flavor as possible, I lightly toast the yellow curry powder with the onions and garlic prior to adding any of the liquid ingredients.

What to Serve with this Vegan Lentil Curry Soup

This Vegan Lentil Curry Soup has it all, so it works well for lunch or a light dinner. The lentils provide protein, while the potatoes give this healthy soup staying power. I like to season it with a bit of fresh lemon juice, salt and pepper and, if I’m feeling spicy, I’ll add a dash of hot sauce. I little bit of garlic naan makes for a great dipping vessel.
