This slow cooker curry lentil soup cooks for ten hours while you do other things. You’ll come home to a delicious, tummy-warming dinner!

Some days just seem to go on forever. You look up at the clock and it says the same time it said an hour ago, and you know the batteries aren’t dead. But other days…

On other days, there just are not enough hours in the days. We run, run, run just to realize we still don’t have enough time to get everything finished. Those are the days this recipe was made for.

What Is Curry Lentil Soup?

While this does have some curry flavor, I wouldn’t consider this an Indian dish. It definitely has that sort of flavor, but I guess you could say it’s pretty Americanized.

The curry flavor here is mild and the soup is comforting. It’s filling and full of good nutrition. You can make it vegan/vegetarian or not, depending on the broth you use. It’s just a tasty, all-around lentil soup. It also makes a large amount so you can freeze some for future meals.

What To Serve With Slow Cooker Curry Lentil Soup

  • Flatbread is wonderful with this soup.
  • A green side salad.
  • Rice, either on the side or mixed in.
  • Ladled over a baked sweet potato or regular baked potato.

Other Methods For Making Curry Lentil Soup

  • Stovetop – You can make this on the stovetop in a large stock pot. Prepare everything according to the recipe, but instead of putting it in a slow cooker, cook it on the stove. You’ll want to keep the soup at a simmer and watch the liquid content as it cooks. You may need to add more.
  • Instant Pot – You can also cook this in an Instant Pot, but you’ll need to cut the recipe in half so it will fit. Sauté the vegetables directly in the IP on sauté mode. Then add everything else, secure the lid, and set the IP to high pressure. Adjust the time with manual mode to 10 minutes. Note that the older your lentils are, the longer cooking time they will need. If 10 minutes isn’t enough, simply replace the lid after checking them, and cook in 5 to 10-minute intervals until the lentils are done.

How To Store Curry Lentil Soup

This will keep in the fridge for up to 3 days. Any portion of the soup left over after that should be frozen.

How Long Can You Freeze Lentil Soup For?

This soup will keep in the freezer for up to 6 months. This is a great soup to freeze in portioned, single servings.

How To Thaw Lentil Soup

The easiest way to thaw this is in the microwave or in a pot on the stovetop.

What You’ll Need

Oil – This can be any oil you usually like to sauté with. I used coconut oil, but use what works for you.

Carrots – I used baby carrots because that’s what I had on hand. If you have full-size carrots, use the skinniest ones you have in the bunch. Peel them, and slice them thin.

Celery – Slice these thin.

Red onion – These should be chopped very small for a better texture in the finished soup.

Garlic powder – I used garlic granules because that’s what I had on hand. But garlic powder is what people usually have. Either will work.

Dry brown lentils– You’ll want to rinse these first and check for any dirt clumps or rocks. Rinse in a fine-meshed sieve or colander.

Curry powder

Ground cumin

Ground coriander – This is optional, but adds a nice flavor, even in that small amount.

Vegetable broth – You can also use chicken broth if you prefer. Look for broth with no added sugar or dextrose and opt for low sodium if you can.

Canned diced tomatoes – These are just plain, diced tomatoes in a can. Do not use fire-roasted tomatoes. Just the plain variety is what you want here.

FAQs

Do I need to rinse lentils before making soup? ›

The other good news: Lentils don't need to soak as beans do (though you do need to sort and rinse them before cooking). Different types of lentils cook in different amounts of time. Red lentils are the fastest cooking and they dissolve as they cook and make for a smooth soup.

Why is my lentil soup so thick? ›

Go easy—if you purée the soup too much, it will get too thick and you'll lose the integrity of the lentils. If you don't have an immersion blender, transfer a few cups of the soup to a standard blender and purée, then return the blended soup to the pot.

Do lentils soak up broth? ›

Lentils aren't rice—they don't need to absorb every last drop of cooking liquid. They're more like pasta: best cooked in an abundance of water or stock. Bring your liquid up to a boil, add your lentils, then turn down your heat to a simmer for at least 25-30 minutes.

Will lentils soften in soup? ›

If you're making a homey soup or stew, either regular green or brown lentils would be an excellent choice. Instead of holding their shape, they soften and become mushy as they cook. I like to add the dried lentils to a big pot of soup and let it simmer until they become tender, about 30 minutes.

What happens if you don't rinse lentils before cooking? ›

While it seems like an unnecessary step, don't skip rinsing your lentils and sifting through them before cooking to remove any stones or debris. It is rare to find stones, but it does happen.

What happens if you don't wash lentils before cooking? ›

A typical packet doesn't say to rinse them. With red lentils the only reaosn I can see for rinsing is to (slightly) reduce foaming; with Puy lentils and some others even that's not an issue and you may lose flavour.

Can you overcook lentils in soup? ›

Yes, you can overcook lentils; they will become mushy. Much depends on the type of lentil you're using. Some cook quicker and hold their shape better than others. To avoid overcooking them, always follow the cooking directions in your recipe and use the type of lentils called for in the ingredient list.

Can you eat too many lentils in soup? ›

Eating half a cup of cooked lentils gives you lots of essential nutrients and their high fiber content makes you feel full. However, the fiber in lentils can be hard for your body to break down. Eating too many lentils can cause gas, bloating, and cramping.

What is the white stuff in lentil soup? ›

Those look to be radicles (embryonic stems, the part the root grows from) that have separated from the lentils. If you look closely at the less squished lentils in your soup, you'll probably see some with the radicles still attached.

Why did my lentil soup turn black? ›

the color change you've observed is from oxidation. If you want to prevent this, lay some plastic wrap over the surface of your lentils to prevent air from getting to them, or add some acid, like lime juice, to the recipe.

What color lentils are best for soup? ›

I recommend using green or French green lentils because they hold their shape in the soup, adding satisfying texture. Brown lentils are also a fine option.

Why did my lentil soup turn brown? ›

As the veggies hit the boiling water, volatile acids are released into the water and are carried away in the steam. When the pot is covered, the steam and the acids it contains are forced back into the water. Once there, the acids react with the chlorophyll in the vegetables, turning them an unsightly shade of brown.

Why is my lentil soup tasteless? ›

Not adding any aromatics to the pot.

Follow this tip: Add a few cloves of garlic, a bay leaf, a spring of rosemary, half of an onion, or a combination of these aromatics to the cooking water or stock to help flavor the lentils.

Why does lentil soup upset my stomach? ›

Eating lentils can cause gas and bloating because they're high in fiber that your body is unable to break down. While fiber plays a large role in supporting and regulating your digestive system and bowel movements, it can also produce bacteria that leads to cramping and gas pains.

What is the secret to cooking lentils? ›

To cook, cover the lentils with plenty of water or stock—about 3 cups for each cup of dry lentils. Lentils swell in size, but they don't absorb the extra water; just drain them when they're done. Once you bring the liquid to a boil, cover the pan and reduce the heat to maintain a gentle simmer.

Is it OK not to rinse red lentils? ›

Lentils do not require it but can be soaked in order to reduce cooking time by about half. Before cooking, rinse lentils in cold water, pick over to remove debris or shrivelled lentils, then drain.

How long to rinse lentils before cooking? ›

Swish the water, drain, and repeat until the water runs clear. This usually takes six or seven rinses for red lentils, split peas and moong dhal, and as little as two for green or brown lentils.

How important is it to rinse red lentils? ›

It's best to be safe and rinse and sift through them before cooking, because no one wants to break a tooth by biting down on a rock. Follow this tip: Give the lentils a good rinse in a colander to remove any debris and sift through them to be sure there are no hidden stones tucked among the legumes.
