Cream of Leek and Sweet Potato Soup
This Cream of Leek and Sweet Potato Soup is so silky and creamy, it’s the perfect dish to warm your body and soul on a cold winter day. Best of all, it’s super easy, and crazy quick, to make!
A few weeks ago I attended a specialized photo workshop, in an effort to perfect my skills and expand my technical knowledge a little bit. The subject that day was Winter Landscapes. I know, it has nothing to do with food, but sometimes, I feel it’s good to “think outside the box” and look at other things than just food through the lens of my camera.
So anyway, needless to say that the workshop took place outside — on a fairly cold winter morning — and lord only knows I am not a winter person. But I had a very lovely time nonetheless, and managed to take a few very decent pictures, too!
After spending all morning out in the snow and cold, we headed back to the workroom where we were greeted with a warm bowl of Cream of Leek and Sweet Potato Soup. This very Cream of Leek and Sweet Potato Soup…
Not only was the steaming hot soup more than welcome, it was also the most delicious and comforting and delicious soup ever. In fact, it was so crazy delicious, I just HAD to ask for the recipe! And honestly, I couldn’t believe how simple the list of ingredients, and instructions, too!
This is probably the easiest soup I’ve ever made. Well, that didn’t come out of a can, that is… And when soup this delicious is that easy to make, who even needs cans, anyway?
To make it, first heat a little bit of olive oil in a large saucepan set over medium heat. Add a chopped leek and two garlic cloves and cook until slightly softened, golden and fragrant, about 2 minutes.
Then, add a few diced sweet potatoes, followed by some vegetable broth, water, thyme, salt and pepper; bring all that to a simmer.
Cover and cook until the sweet potatoes are fork tender, which shouldn’t take much longer than 5 minutes.
Carefully ladle the soup into a high-speed blender and process until smooth and creamy, about 30 seconds.
If you didn’t have one of those fancy shmancy high speed blenders, you could also use a regular blender, a food processor or even a stick blender. Your soup won’t come out quite as silky and creamy, but it will taste just as good!
That’s it! You’re done! Told you it was easy, didn’t I?
All that’s left to do is serve your soup promptly, garnished with a dollop of sour cream or plain yogurt (use dairy-free option to keep vegan) finely chopped leeks and fresh thyme, if you are so inclined.
And enjoy!

For the leak and sweet potato soup. Is it ok if I use just water? If I don’t have chicken stock
Thank you!!
Sure thing Ana, although you’re probably gonna want to adjust the seasoning a little bit…
Delicious! And very easy. Thank you! Also, the table with nutritional info is helpful however does not show the amount of ounces per serving? Please let us know.
Thank you! Celeste
The nutrition facts are per one of four servings, so 1/4 of the recipe.
Never cooked with Leeks before, do use the whole thing dark green tops or just the bottom?
I use the whole thing, but you can use just the white parts if you prefer!
I’ve made this twice, 1st with veggie stock (but I don’t love veggie stock, all I can taste is celery), 2nd time with water and threw in a small onion for more flavor. Easy and tasty! However, I’m terrible at sweet potatoes, and the 2nd time I bought golden(?) ones? Don’t do this, it turns a really weird green color. Used wand blender both times for a really long time and still comes out silky, just need patience. And an apron. I’ve added this to my winter repertoire, thanks!!!
just made this last night for me and my daughters who eat plant based. I happened to have a sweet potato and leek in the frig and it was delicious and filling. We all loved it and it only made 3 servings so i will be making it again this weekend.
thanks for a delicious, easy and healthy recipe!

Absolutely!

Super happy to hear, Elizabeth! Thanks much for the great feedback!:)
Simple, compliant with my diet, and yummy!
*FIST BUMP* 🙂

Glad to hear it was to your liking, Nerak. Thanks a bunch for the great feedback! 🙂
Delicious! I only had one sweet potato so added a carrot and two small white potatoes and a dollop of butter.
Rich, sweet and flavoursome. Will be making this again.
Thank you, Beth! Glad you liked it! 🙂
Oh my goodness this was fantastic! Thank you for sharing.x
Thank YOU, Grietjie, for taking the time to let me know! 🙂
Simple but delicious!
My go to soup recipe when I have leeks. Yum!
Do I have to cook the sweet potatoes before I put them into the pot of boiling water?
No. The sweet potatoes will cook in the simmering broth.
Tried this recipe today not exactly to the measurements nor the mentioned broth but turned out fabulous regardless. Thanks for the guideline I wouldn’t have known how to make this without it. I definitely recommend.
So easy to make and quick! Very very good. Will be one of my go tos.
I made some homemade vegetable stock late last week, had extra leeks and sweet potatoes in the crisper. When I googled a recipe for those ingredients this soup is what I found. Fast and fabulous lunch for the three of us working from home on a gray, snowy, windy Monday.
I used more leeks and broth than called for which means we have more.
Husband and 25 year old daughter rate it restaurant quality.
You are right it is fast. However I began with butter and addzd asparagus. Whe I could not find potato I look at sweet potatos. And it worked just right added heavy cream donot forget the onion. Done thank for the assist
Absolutely amazing
Delicious! and so quick and easy! I used my immersion blender to make it even easier for myself. In our CSA this week we got some beautiful leeks and sweet potatoes, I’m so glad I found this recipe 🙂 Definitely a new fall favorite!
Love this! We had it for our Thanksgiving Day lunch, and now it will be my go to soup to bring to our larger Christmas Eve gathering. Thank you!
So very honored and real happy to hear, Andra! Thanks a bunch for taking the time to let me know! 🙂
Really loved this! Easy to make.
Excellent
Ridiculously easy and Delicious!!!!
LOVED IT! I’ve never commented on a recipe before but I enjoyed this so much and it was so simple and quick that I feel I just had to. I made this today with slight adjustments according to what I had which was a large purple sweet potato, 4 large leeks (to use them up or they would have been wasted) 3 cloves of garlic, some dried thyme, and salt and pepper. I never use stock as shop bought cubes etc, are high in salt and/or UPFs. so I just used water. I didn’t have yoghurt so I sprinkled on some pumpkin seeds and walnuts for the good fats. It was sooooo delicious. I think the thyme made it as it went so well with it. I am rarely happy with my home made soups for one reason or aother but I loved this and this will now be a regular for me.
Please clarify.
The leek: do you use only the white part? Or the white and green?
The weight of the sweet potatoes: is the 750g the unpeeled weight? Or the peeled weight?
What can I add to get more protein?
