I've said this many times before, but there is truly no weeknight meal I love more than soup. Even during the hottest weeks of summer, I can't resist the allure of a simple, one-pot soup. It's typically very easy to make, and there are always leftovers for the next day's lunch.

Plus, since my husband and I have different dietary preferences (I'm mostly vegan, he's not), soup is an easy dish to bridge that gap. More often than not, he doesn't mind option for a vegan soup. And if he really wants to add meat, he can cook it separately and add it in at the end.

This Vegan Lentil and Sweet Potato Curry Soup is one of his favorites. It's packed with flavorful, warming spices, hearty lentils and some leafy greens for good measure. Sweet potatoes add a bit of bulk, and tomatoes add the perfect amount of acidity and deep flavor.

Even if you think you don't like lentils, try this soup! If you really don't like lentils, you can always sub with chickpeas, but I think you'll love this either way.

The best part? This Curry Lentil Soup is great for leftovers. If you don't think you'll eat it right away, freeze it and reheat on a rainy (or snowy) day in the future. My husband loves taking this to work. He eats it with some crusty sourdough bread –– the perfect lunch!

What kind of lentils should I use?

While red and yellow lentils are well suited for a puréed lentil soup, they don't hold up well in this kind of soup. Opt instead for brown or green lentils, which hold their shape. You don't want to end up with a pile of mush!

We opt for French green lentils in this recipe. They’re smaller, darker in color, and more flavorful than regular green lentils. I love the texture that they add to this soup, but if you can't find any, regular green lentils will be fine.

How to build a flavorful soup base

The key to this soup is adding plenty of flavor to the base. Don't worry –– there aren't a ton of crazy ingredients –– just a few high quality flavor enhancers.

The base starts with onion, garlic and ginger, sautéed until browned, tender and super flavorful.

Tomato paste is one of my favorite ingredients for soup. It adds SO much delicious concentrated tomato flavor. Just be sure to buy high quality paste (the stuff that comes in a tube). It makes all the difference!

When it comes to spices, we're keeping it pretty simple with yellow curry powder and a dash of cinnamon. Again, opt for a high quality curry powder, which will deliver plenty of flavor.

Mild curry will be a bit milder (duh!), while madras curry powder will add a spicy punch. Choose whichever you prefer!

In addition to vegetable broth, full-fat coconut milk is a wonderful addition. It adds creaminess, depth and a just a touch of coconut that pairs perfectly with the curry powder.

To add more vegetables, we opted for peeled and diced sweet potato and leafy kale. There are plenty of other vegetables you could add or substitute. We'd opt for cauliflower, regular potatoes instead of sweet potatoes, carrots, zucchini, etc.

The only soup pot you need in your life

For someone that makes soup as often as I do, there's no piece of kitchen equipment I use more than my Le Creuset Dutch Oven. (Except for maybe my blender.)

If you already have a Le Creuset Signature Dutch Oven, you know what I mean. It's enameled cast iron (which means yes, it's heavy), but it holds up for years and years (seriously, decades!). I truly believe every single kitchen needs a Le Creuset Dutch Oven. Very much worth the investment!

Cast iron distributes heat evenly and retains heat perfectly. The enameled surface also prevents sticking, and there's no need to season these pans unlike other cast iron. You can read more about Le Creuset Dutch Ovens here!

I adore this color. It's a gorgeous matte white that I would imagine looks great in just about any kitchen. But I also love some of their brighter colors. You can choose from 15+ color options here!
