Weight Watchers Recipe of the Day: Spicy Red Lentil Soup with Lemon
I first tasted red lentil soup in London’s Books for Cooks, a tiny book shop with an even tinier test kitchen sandwiched between the bookshelves at the back of the store, where customers can sample splendid soups, mouthwatering home-baked cakes and other delectable dishes made from recipes in the thousands of cookbooks on their shelves.

I was immediately smitten but had never attempted to recreate the soup at home, until last week when a vegan version with kale I enjoyed at Wild Flower Bread Company reawakened the desire.
Recipe Notes
After checking out several recipes both online and in several cookbooks, I came up with this delightful concoction.
Unlike the green or brown varieties, red lentils are already hulled and split so they cook much faster. But their delicate salmon pink color fades to a golden yellow hue as they cook. So to give my soup more color, I added a bit of tomato paste.
When done, I gave the soup a blitz with my hand-held blender (affiliate link) right in the pot, taking the texture somewhere between chunky and smooth.

Just before serving, I topped it with a dollop of yogurt.
A drizzle of olive oil or pomegranate syrup or smattering of crispy onions as suggested in one recipe would be nice as well.
Lighter and brighter than more traditional lentil soups I’ve made, this is a recipe I plan to return to often.

Itโs like you have2 Different recipes. One in the video and the other one.. So I guess you use whichever??
Made this today with brown lentils and no tomato paste. It is very good, had some for lunch. It will probably taste even better tomorrow. Very good, nice change of pace. Thank you
I want to make but your recipe says 6 cups vegetable broth and the video says 2 cups. Did I miss something?
Hi Cheryl,
The video is for a different lentil soup recipe. Follow the written instructions for my Spicy Red Lentil Soup. Hope this helps. Martha
Very good and so easy. I had everything on hand! I made it as written and it was perfect.
Thanks Jennifer!
I wasn’t able to find red lentils? Would regular ones work just as well? Or does the red make or break the flavor?
HI Hay, I’ve only made it with red lentils so I can’t really say for sure…
Well I already had all the ingredients so I went ahead and used regular brown ones. They worked just fine. Can’t wait to try it again with the red! Yum.
Thanks for letting us know Haylie!
This soup looks very promising & most importantly requires very less ingredients! And thank you so much for explaining in detail about the red lentils! It was really useful. Thank you!
