Ingredients you need
Here is what you’ll need to make this hearty red lentil soup. I promise, there’s nothing too fancy. You’ll have most of these things in your pantry and fridge or freezer.
- Red lentils: Of course. Make sure to use red split lentils as they’ll cook faster.
- Onion and garlic: To create a wonderfully rich and sweet flavor.
- Spices: A simple mix of cumin, turmeric, and black pepper.
- Carrots: To add a bit of sweetness.
- Spinach: Fresh or frozen. Because we should never forget that we all need to eat our greens!
- Vegetable broth (or water): If I don’t have vegetable broth available, I simply add water to this recipe. The flavor from the spices, lentils, and veggies gives it enough depth to make it delicious.
- The juice of one lemon: Optional, to add a bit of zest and acidity. I strongly recommend you try it!
- Parsley: to garnish the soup.
- Olive oil and salt
What are red split lentils?
Red split lentils are different from red lentils. They are made from red lentils with a brownish skin. the skin is removed and then the lentils are split into two halves. This helps to cook them much faster than normal lentisl.
They are a bright orange when dry but turn golden yellow when cooked!
How to make red lentil soup
1. Sauté the onion in some olive oil on low heat, then add the crushed garlic and spices. Let the spices cook for around a minute to bring out the flavors, but don’t overcook them, or they could turn bitter!
2. Add the carrots cut into chunks and the red lentils. Stir for a couple of minutes to let the lentils absorb the flavors, then add the vegetable broth or water and let everything cook for around 20 minutes. There is no need to blend the soup. The lentils will naturally puree and reach a thick, creamy consistency. If you like your soup more watery, add a bit more broth or water when it’s almost ready.
3. When lentils are cooked and falling apart, add the spinach and cook for about a minute (If you are using frozen spinach, add them 5 minutes earlier).
4. Serve hot, garnished with some fresh parsley.
5. Optional: add the juice of one lemon to add a touch of freshness (plus, the lemon, with its vitamin C, will help you to absorb the iron in the lentils and spinach).
Do you need to soak or pre-cook lentils for this recipe?
Absolutely not! The amazing thing about red lentils is that they’ll cook in around 15-20 minutes.
Usually, you’ll need a 1:3 ratio of lentils to liquid, which means that if you use 1 cup of red lentils, you’ll need 3 cups of water. But if you like your soup thinner, simply add a bit more broth. For a thicker soup, let it simmer for an extra 5-10 minutes. There is no risk of overcooking the lentils.
So, all you need to do to cook red lentils is quickly rinse them under cold water and chuck them straight into the pan.
Then cover with water or broth, bring to a boil, reduce the heat to a gentle simmer and let them cook for 15-20 minutes until they start to fall apart and become creamy and soft.
Is red lentil soup good for you?
Yes! Red lentil soup (or any lentil soup for that matter) is nourishing, creamy, and delicious, and also incredibly healthy. Lentils are a little nutrition powerhouse.
They are one of the best plant-based protein sources, with over 25% of their calories coming straight from protein. Which makes them the perfect meat substitute if you want to include more plant-based meals into your diet.
Plus, they are rich in fiber, making them incredibly filling yet low in calories. They are also packed with B vitamins, zinc, magnesium, and potassium.
So make sure to include lentils in your diet!
How to store and meal prep
This is a great soup to make in advance for meal prep. It’s one of those soups that gets better when you reheat it, especially on the stove.
In the fridge: Pour the soup into airtight containers and keep refrigerated for 3-4 days.
In the freezer: Divide the soup into freezer-safe containers. You can freeze it for up to 3 months. Once you are ready to eat it, thaw it overnight in the refrigerator before warming it up.
You can then reheat in the microwave, or, my preferred method, reheat it on the stove, adding half a cup of water to loosen it up a bit for perfect consistency.
- I use a 1:3 ratio for this recipe: 3 cups of liquid for 1 cup of red lentils. I like my soup really thick. But feel free to adjust this to your liking.
- Use any greens you like: anything goes – kale, chard, collard greens, cabbage. Just make sure you add your greens a bit sooner, depending on their cooking time.
- You can make this soup with any other type of lentils, but it will take longer to cook (30 to 45 minutes, depending on the lentils), and the result won’t be as creamy. You might need to use an immersion blender to give it a blitz or two to achieve the perfect creamy consistency.
