Our quick and easy Lentil Soup Recipe with Kale is healthy and delicious with a surprisingly robust flavor.

This simple lentil soup has been a staple in our house since 2012. It’s one of those recipes that surprises me every time I make it. The amount of flavor you get from a few fresh vegetables, tomato paste, vegetable broth and lentils is truly amazing.

For years this has been my go-to recipe when my husband is traveling for work. I can make a pot of this lentil soup recipe and enjoy it all week long, and never get tired of it! Since this is a vegan soup, it will keep in the refrigerator for days and still taste fresh. I really love this soup, and it makes me feel better about the cookies I ate over the weekend 🙂 It’s all in the balance – right?

My husband also adores this soup and wishes I’d make it more often, when he’s home. It’s perfect for lunches too… think meal prep for the entire week!

Are lentils really that good for you?

Lentils are from the legume family and boast a respectable amount of vitamins, dietary fiber, minerals and protein. They’re filling, easy to make and inexpensive, so that makes them great for adding to salads, casseroles, soups and stews. Health Magazine named them one of the five healthiest foods in the world. Let’s eat more lentils!

How do you store lentils?

Dried lentils will keep for several years if stored in an airtight container in a cool, dark location. Once cooked, lentils should be refrigerated and will stay edible for 5 to 7 days. Cooked lentils freeze well for up to 6 months. As with any dried bean, be sure to wash and pick over the lentils removing debris before cooking.

For this lentil soup recipe, we use two varieties of dried lentils.

There are many varieties of lentils available at most grocery stores, and online. Some of the more common types of lentils are brown, Puy, green, red or yellow, and Beluga. Black Beluga lentils are some of our favorites, especially when added to warm salads and grain bowls like those served at Panera Bread and CAVA restaurants.

For our lentil soup recipe we use a combination of red lentils and an equal amount of green, or Puy lentils. Red lentils cook quickly, break down easily and have a nice sweet, nutty flavor. Even though red lentils are not the most nutritious powerhouse variety, I love to cook with them anyway. When added to soups and stews they add a delicate texture and flavor we really love.

Puy Lentils come from the Le Puy region in France and are similar to green lentils, only smaller. Try finding them online if they’re not available in your local stores.

A bowl of soup with carrots, lentils and kale

This lentil soup with kale is quick and easy to make:

First, sauté the carrots, onion and garlic in a little olive oil.
Add red pepper flakes and fresh thyme leaves and sauté until fragrant.
Pour in the vegetable broth and add the rinsed lentils. Cover and simmer for 30 minutes.
Stir in the remaining ingredients: tomato paste, brown sugar, vinegar, garam masala, black pepper and the chopped kale.
Simmer 10 minutes more or until the kale is wilted.
Serve with a slice of hearty bread and enjoy 🙂

For an easy shortcut, buy pre-washed, chopped kale leaves. You can even use a combination of hearty greens like Swiss Chard, baby kale leaves and/or spinach. This soup just makes you feel better when you eat it. Try it and see!

Can you freeze this lentil soup recipe?

Our lentil soup freezes very well. I like to portion the soup out into individual size containers and thaw only what’s needed overnight in the refrigerator. Rewarm the soup gently in the microwave and serve.

You can also make this lentil soup ahead of time and add kale just before serving. Kale is very sturdy and holds up better than spinach or other leafy greens, making it great for freezing.

A big pot of this healthy soup is like wearing a comfortable old sweater. You know … the one your family threatens to throw away if they ever get their hands on it. Yes, I have an ugly sweater that I love. My family makes fun of me every time I wear it. But they sure do love this soup!
