Easy, healthy Slow Cooker Red Lentil Curry with Sweet Potatoes and coconut milk. Creamy, delicious vegan recipe with the perfect amount of Indian spice!

I first made this simple red lentil curry recipe when we moved into our new home and—after two weeks straight of moving-stress-induced takeout dinners—I needed a healthy reset.

WELL, here I am again! I’ve spent the last few weeks eating out as often as I’ve eaten in. It’s been delicious and fun and I’m likely to do it again, which is exactly why I need more easy red lentil recipes like this one in my life this week.

For me, it’s much easier to be excited about eating at home when I’m genuinely looking forward to the food in my refrigerator. Having delicious food on hand helps me avoid the temptation to say “Forget it—let’s go out” or to reach for a bag of chips instead of going to the effort to cook.

This Red Lentil Curry is absolutely scrumptious. I feel giddy and impatient to eat it every time I warm up a bowl!

More about Red Lentils

If you are not ultra familiar with red lentils, then I am so pleased to introduce you to one of the least-expensive, best-tasting healthy foods on the planet.

Lentils are a member of the legume family, along with split peas, peanuts, chickpeas, and more. A few reasons to add them to your pantry (in addition to how inexpensive they are):

  • Versatility. Red lentils are mild and readily absorb spices, meaning they can soak up any flavors you add to them. They’re an easy ingredient in a wide range of recipes that range from more Indian-spiced dishes like this Instant Pot Lentil Curry to more traditional ones like Instant Pot Lentil Soup.
  • High in Fiber and Protein. That means this Red Lentil Curry (and other recipes with lentils) will keep you full and happy, no meat required.
  • Low on Calories. Just 230 in a whole cup!
  • Big on Nutrients. Think iron, folate, and more.
  • Creamy but Not Mushy. With their pleasant texture, lentils are a delight to eat.
  • Fast. Lentils do not need to be soaked before cooking, saving you a recipe step. They do need to be rinsed to remove any dirt or stray bits, but this takes only a minute or two.

How to Make a Red Lentil Curry with Max Flavor and Minimal Effort

Today’s Slow Cooker Red Lentil Curry is one of my absolute favorite ways to spice and flavor the versatile red lentil.

In a bit of a mashup, I ended up with an Indian-meets-Thai approach. (Does this make this curry Asian fusion? If yes, according to my last issue of Bon Appetit, we are right on trend!)

  • Thai Red Curry Paste. Think of this ingredient as a jar of instant flavor. It’s widely available and sold in the international food or Asian food section of almost any grocery store. Once you have it, you can use it to make many more healthy recipes, including Thai Chicken Curry, Coconut Curry, and Pumpkin Curry Soup.
  • Garam Masala. This ingredient is a blend of many spices and a staple in Indian cooking. You can find garam masala in the spice section of many grocery stores or online here. Once you have a bottle, in addition to this Slow Cooker Red Lentil Curry, you can use it to make my healthy Instant Pot Chicken Tikka MasalaPaneer Tikka Masala, and Instant Pot Butter Chicken.

Spices like garam masala and the red curry paste are key allies to cooking that is a) healthy (spice = big taste without extra fat), b) easy (you can measure one spoonful of one spice blend instead of 10 of individual spices), and c) DELISH.

The sweet potatoes and lentils calm the spices so they are warm and flavorful but not hot, making this red lentil curry recipe accessible to more sensitive palates.

Creamy Curry without the Cream

One of my favorite parts of Indian red lentil curry is how creamy it is. I love the way the sauce coats the rice and how rich it makes even an ingredient as healthy as lentils taste.

In a restaurant, that creaminess often comes from cream (surprise!), but I’ve found that you can achieve a similar effect (and make the red lentil curry vegan) by using coconut milk. I used light coconut milk and the curry was plenty thick and satisfying for us, but if you wanted extra indulgence, you could use full fat instead.

Slow Cooker Red Lentil Curry with Sweet Potato is an easy vegan dinner that's great for meal prep!

The next time you are thinking about takeout, instead of picking up the phone, pull out your crock pot and give this red lentil curry recipe a try!
