How to make this Carrot and Lentil Soup

This Carrot and Lentil Soup actually might be the easiest soup in the world to make. If there is a simpler soup out there, please let me know because I want to hear about it.

Chop the onion and garlic as finely as you feel like.
Peel and grate the carrot and ginger. If you have a grater attachment on your food processor, your job will be even easier. I used a box grater.
Put the onion, garlic, grated carrots and ginger into a Dutch oven or the insert of an Instant Pot
Add the lentils, spices, coconut milk and water.
If you’re using the stovetop method, bring the soup to a boil over high heat, then reduce the heat to medium-low, give the soup a good stir, then cover, and cook for 20 minutes.
If you’re using the Instant Pot method, simply lock the lid into place and set the Instant Pot to the high-pressure mode for 10 minutes.
Serve with a squeeze of lime juice and enjoy!

Tips for success

These tips will help you make the best Carrot and Lentil Soup:

Use the thickest canned coconut milk you can find. That means shaking the can when you’re in the store and rejecting any cans where you can hear the liquid sloshing around. (Tip courtesy of Chef Heidi Fink.)
Make sure your red lentils are somewhat fresh. If you have a jar of red lentils at the back of your cupboard that has been there for a decade or more, you’re not alone. But there’s a good chance they’re too old and will not soften as nicely. Dried legumes have a super long shelf-life, that’s for sure, but even lentils have their limits.
Making a bigger batch of soup? Great idea. You can easily double this recipe and it’ll still fit into the Instant Pot. This size batch fits perfectly into my Dutch oven though.
Use the freshest ginger and garlic you can get your hands on. It really helps make the soup taste better, and it makes a big difference in the satisfaction you’ll get from making it. If you’ve never had the pleasure of slicing through a juicy, fresh-from-the-ground garlic clove, it’s worth seeking out!
Once the soup is done cooking, keep it covered but let it sit off the heat for 15-30 minutes. It helps develop the flavours a bit more—which is great because we didn’t sauté the onions or toast the spices, so we need all the flavour development we can get.
Also in the flavour development realm—this soup is ten times better after it’s been in the fridge for a while. Enjoy all the “fridge-cooked” leftovers!
Don’t forget that lime juice finish. It’s a game-changer.

What goes well with this Carrot and Lentil Soup?

This soup is very satisfying on its own. The lentils make it super filling. But as with most soups, I find it hard to resist a bit of bread on the side. I recently had it with my 2 Ingredient Flatbread (the all-purpose flour and yogurt version) and it was the most perfect thing ever.

I would also be quite happy eating it beside a grilled cheese and homemade chutney sandwich.

Storage, freezing, and reheating tips

This Carrot and Lentil Soup is great eaten right away but gets incrementally better after 1-4 days in the fridge after which it starts to decline.

To store this soup in the fridge, keep it in a sealed food container for up to 4 days.

This soup freezes well as long as it is well-sealed. A glass or plastic food storage container is perfect. I have also been known to use freezer-safe Mason jars—just be sure to leave plenty of room in the top so it doesn’t explode.

This soup is simple to reheat in the microwave or on the stovetop. Lentil soup sticks and burns easily so if you’re using a pot on the stovetop, be sure to stir regularly and keep it over medium heat.

The soup will thicken up a bit as the lentils continue absorbing the liquid. I happen to love the thicker consistency but you can thin it out slightly with water if you prefer.

Frequently asked questions

Can I use another kind of lentil if I don’t have red lentils?

Yes, any other lentil or split pea will work, but the cooking time will change. It will also affect the final look and texture of the soup. Red lentils are really cheap and readily available, so I recommend sticking with them.

Can I use dried ginger instead of fresh ginger?

Yes, but it will lack a bit of the punch you get from fresh ginger. If using ground ginger, I recommend using 1 Tablespoon.

I usually blend my carrot soup with an immersion blender. Can I blend this one?

Sure, but I personally love the texture of the lentils and the grated carrots. I love blended soup as much as the next gal, but in my opinion, this one is perfect as is.

Shouldn’t I sauté the onions in olive oil first to enhance the flavour?

Sure! I almost always start soups by sautéing the onions and toasting the spices. This soup takes a lot of shortcuts that way, but I love the flavour so much anyway and I find it liberating to just chuck everything in at once!

Can I use vegetable broth instead of water?

Of course you can! But it’s not essential. There’s something really nice and simple about just using good ol’ plain water. This soup is so flavourful either way.
