(Slow Cooker) Ginger Curry Lentil Soup with Sweet Potatoes

Easy to make and deeply satisfying, a simple adjustment makes this soul-warming soup vegan-friendly. 

 

 

A few weeks into my son John’s first semester at college, a friend asked him to sign a Meatless Monday pledge. He figured one day a week without meat wouldn’t be too hard, so he put pen to paper.

Several weeks in, I asked him how it was going. With no hesitation, he said it was really hard. Some Mondays he simply forgot. When he remembered, the smell of bacon tempted him at breakfast and crisp turkey paninis called his name at lunch. By dinnertime, he’d walk into the dining hall, ravenous after a long sports practice, and see juicy burgers, curried chicken, or glazed salmon. Food choices at colleges these days are rather impressive—and a buffet line puts the many temptations front and center!

When he came home for Christmas break, I figured I’d help him get back on track. If we all went meatless together, the challenge would be infinitely easier, right?

The first Monday, I completely forgot. So I made up for it on Wednesday of the same week, deciding we would still be true to the spirit of giving up meat one day a week, even if the alliteration was lacking.

A reader named Mary Lou first shared a version of the following recipe with me over five years ago. Mary Lou has faithfully prepared my recipes since the early days of my blog, regularly commenting and providing thoughtful feedback. She thought I might enjoy the flavor and ease of this filling soup as much as she did—and she was right.

 

Easy to make and deeply satisfying, a simple adjustment makes this soul-warming soup vegan-friendly. The aroma while cooking is amazing, too!

When I made it most recently, I was prepared for a groan or two from a family member who is decidedly not a fan of lentils or sweet potatoes. I served the soup without comment (hoping a side of cornbread would boost his spirits), and was completely shocked when everyone around the table raved. I think one teenage boy actually uttered the words “This is awesome!

Maybe the soup tasted especially good on a cold day, and perhaps somebody mistook the sweet potatoes for carrots. Regardless, I was delighted that a soup I’ve always enjoyed was suddenly a hit with all.

It was also a reminder that being vague about what’s on the menu can be helpful when feeding “selective” diners. When asked what was for dinner, I simply called it a hearty soup that one of my readers shared with me many years ago. This way, nobody took the first bite with his mind already made up.

Instead, a handful of well-chosen seasonings create a flavorful broth, making the hearty (dare I say meaty) lentils and filling potatoes inviting to even the most enthusiastic of meat eaters.

(Slow Cooker) Ginger Curry Lentil Soup with Sweet Potatoes
The aroma wafting from your kitchen while this savory soup cooks is delightful. Leftovers improve with age, although they will become more stew-like as the lentils continue to absorb liquid over time. If desired, simply thin with additional broth.
Yield: 8 servings
Ingredients
  • 2 medium sweet potatoes, chopped (About 16 ounces or 3 cups chopped; I don’t peel, but you may if preferred)
  • 1 cup dry brown lentils
  • 1 cup chopped yellow onion
  • 1 medium fresh jalapeno, seeded and finely chopped (or 1/4 teaspoon cayenne pepper)
  • 3 cloves garlic, minced
  • 3 (14.5-oz) cans (or 5 cups) chicken broth (use vegetable broth for vegan/vegetarian option; have extra on hand to thin, if desired)
  • 1 (14.5-oz) can diced tomatoes, with juices
  • 1 tablespoon curry powder
  • 1 tablespoon minced fresh ginger*
  • 3-4 cups lightly packed kale or spinach, roughly chopped
  • 1/2 tablespoon honey**
  • 1 teaspoon kosher salt and freshly ground pepper to taste
  • Optional garnishes: plain yogurt or sour cream, jalapeno, crushed red pepper
Instructions
  1. In a 4 – 5 quart slow cooker, combine the sweet potatoes, lentils, onion, jalapeño, and garlic. Add the broth, tomatoes with juices, curry, and ginger.
  2. Cover and cook on low-heat setting for 7 – 8 hours or on high-heat setting for 3 1/2 – 4 hours.  (Check a half hour or so early until you know how long it takes for the lentils to become tender, but not mushy, in your slow cooker.)
  3. Add the kale or spinach, honey, salt and pepper during the last 15-30 minutes of cooking.
  4. Check for seasoning (you may wish to add another pinch or two of salt depending on the type of broth used—or perhaps a full teaspoon if using unsalted stock) and garnish with yogurt or sour cream, chili peppers and/or crushed red pepper if desired.
Notes

*My husband claims to not love ginger, but I level off the tablespoon and the resulting flavor is subtle enough that he enjoys the soup without realizing there’s ginger in it.

**This amount of honey will not make the soup sweet, but it does balance the flavor nicely.  You can use maple syrup or brown sugar for a vegan option, or omit if preferred.

    I made this using a pressure cooker because I live at high elevation and it was awesome. Great taste and impressed my husband. Thank you!

    Hi there! I am curious about the yield, or quantity/size of servings. Entering recipe into LoseIt and don’t quite know what to tell it. Thanks so much!

    Bit of a conundrum… I have all the ingredients on hand, except for a slow cooker or crockpot. I’m pretty sure it also works in a regular soup pot on the stove… Any indications of cooking times in that case? (or should it basically be ‘simmer til the lentils are tender’?)

      Hi Jef,
      That should be no problem. Coincidentally, I just made a chili recipe with lentils on the stovetop and simmered it for 30-35 minutes. Like you said, though, just check for the lentils to be tender. Hope you enjoy!

    (Time sensitive) Ok so I made a big mistake. Used green split peas and it’s already all mixed. I could take them out still and go grab some green lentils. Thoughts?

      Oh goodness…of course this has to be the day I am in meetings! The split peas will cook in far less time but could end up tasting delicious in this soup. Please let me know how you made out!

    Thanks for your response! I only have 1 tsp of curry on hand. Would that even make a dent with flavor or would you go for the full TBSP? I was going to run to the store to get more but would have to add it a few hours into cooking. Worth it or not? Also does this tend to be pretty spicy? Feeding it to kids and adults. Thanks again!

      Hi Belinda,
      I would go ahead and make it even if you are low on the curry. I think you will still get a hint of the flavor and be happy with the outcome. If you are concerned about the palates of the kids who will be eating, you might want use the lesser end of the ginger mentioned. My kids enjoy the soup with the full tablespoon but, since ginger is somewhat pungent, you could err on the side of caution. I hope everyone enjoys!

    Looks SO good! Have your tried green or red lentils? I’ve heard red cook differently so wanted to see your thoughts. Thanks!

      It smells as good as it tastes, Belinda! I would not use red lentils (which are often split) or yellow lentils as they will become mushy. Green or French lentils should work just fine. If you try, I hope you enjoy!

    I love lentils and I love curry but have never put the two together, this soup sounds wonderful! And it’s so fun that it can be done in the slow cooker. How great to come home to this after a day of working (or playing)!

      This soup smells as delicious as it tastes, thanks partly to the curry which works so well with the lentils. This recipe is definitely a treat to come home to! Thank you for the thoughtful comment!

      You are going to love it, Winnie! I was just telling my husband that I could eat it every night. Will be making more here soon!

      Good question, Roberta! I used 4 cloves from one head of garlic. I haven’t heard the term “toes” before…good to know! We call the whole thing a head of garlic and the individual pieces the cloves.

    Wow! You are welcome and so happy you liked the recipe Ann! Isn’t the aroma delightful? I need to thaw some of the grass fed ground beef I have in freezer to make the lentil soup recipe you have on here.
