About Lentils

Lentils are a pulse, which is the edible seed of a legume. Other examples of pulses are chickpeas and beans. The difference, though, is that lentils are always dried, and never eaten fresh.

There are a few different varieties of lentils, including green, brown, yellow, red, and black lentils. The size of the lentil varies amongst the different varieties, as does the cooking time.

What’s the Difference Between Lentil Varieties?

The lentil varieties that you commonly find in the store are brown lentils, green lentils and split red lentils. Brown lentils take 20-30 minutes to cook, and green lentils for about 45 minutes. Both the brown and green varieties hold their shape well after cooking, so they are ideal for salads, soups where you want texture, and stews.

Red lentils, on the other hand, are split, and the seed coat is removed, so they are very quick to cook (10-15 minutes). They turn mushy when they are cooked, which makes them perfect for pureed soups like this red lentil soup recipe. And, by the way, red lentils are actually orange, not red. 

If you manage to find black lentils, they are a treat. Also called beluga lentils because they resemble caviar, black lentils are tiny and hold their shape very well after cooking. They’re perfect for salads and side dishes.

What are French Lentils?

You may have come across recipes with French lentils as an ingredient. French lentils are a variety of green lentil. They hold their shape after cooking even better than brown and regular green lentils. However, if you can’t find French lentils, it’s always fine to use regular green lentils in their place.

How to Store Lentils

Store lentils in air-tight containers in a dark, cool & temperature-stable place. Like your pantry, or kitchen cupboard, for example. If properly stored, your lentils will keep for up to a year.

After a year, the lentils will become tougher, less flavourful, and take longer to cook.

About This Red Lentil Soup

The main ingredients for this recipe are items that will keep in your pantry or cupboard for a long time. Lentils, of course, plus cartons of vegetable stock, canned tomatoes, and coconut milk. This is an Indian spiced soup, so I also used a jarred Korma paste. 

The soup will be delicious with just those main ingredients. However, you can also add cauliflower, potatoes, or sweet potatoes if you have them. My addition to this recipe is cauliflower and it is a delicious addition of both taste and texture for this soup.

A dollop of coconut cream and a drizzle of hot sauce are perfect complementary garnishes.

  • Bring to a boil, then reduce heat to a simmer.
  • Cover and allow to simmer 15 minutes, or until lentils and cauliflower are tender

*I used korma, which is a very mild curry sauce. Adjust the quantity according to the spice level of your curry paste.
If you don't have fresh cauliflower, you can use frozen, or you can omit it altogether for a still delicious soup. Or you can replace the cauliflower with the same quantity of peeled potatoes or sweet potatoes.
This soup freezes very well. Just portion it into airtight freezer containers.
Chicken stock can be used in place of vegetable stock for a non-vegan version.
