Author Notes

This is a really simple soup to make, and gently flavored with hints of the Middle East, where I was working until just recently. Za'atar is a spice blend that combines dried hyssop, thyme, and sesame seeds and can be found at Middle Eastern grocers or other specialty stores. I had originally conceived of this as a butternut squash soup, but we had an overload of sweet potatoes in the house and so the recipe was amended, luckily to delicious results. Perfect for an autumnal evening. —Lauren Shockey

Test Kitchen Notes

One of the things we like best about this recipe is how lauren takes a few simple ingredients, adds a couple of exotic touches and manages to produce a dish that's both comforting and thrilling at the same time. The soup itself is silky and hearty, the sweetness of the potatoes tempered by the aromatics; a finishing swirl of zaatar oil (zaatar is a Mediterranean seasoning typically containing sesame seeds, thyme, oregano and salt) and a sprinkling of crumbled feta elevate the soup to sophistication. One cooking note: our soup was a bit thick after we pureed it, but a bit of water brought it to just the right consistency. - A&M —The Editors

What You'll Need
Ingredients
  • 1/4 cup plus 2 tablespoons olive oil
  • 2 tablespoons za'atar (see headnote)
  • 1 tablespoon butter
  • 1 onion, peeled and diced
  • 1 carrot, peeled and diced
  • 1 leek, white part only, rinsed thoroughly and diced
  • 5 medium sweet potatoes, peeled and cut into 1" cubes
  • 6 cups water
  • 2 cups chicken stock
  • 1 bay leaf
  • 1 tablespoon salt
  • 1/4 cup feta cheese
Directions
  1. In a small pot, combine ¼ cup olive oil and the zaatar. Cook over medium heat until hot, but take care not to burn the zaatar. Set aside for at least one hour to cool and infuse.
  2. In a large pot, heat the butter and remaining olive oil over medium high heat. When the butter has melted, add the onion, carrot, and leek, and cook until softened, about five minutes. Add the sweet potato cubes and sauté for another minute. Add the water, stock, and bay leaf, and bring to a boil. Once the soup begins to boil, lower to a simmer and cook for 30 minutes. Check to make sure the sweet potatoes are completely soft. If not, continue cooking until they are.
  3. Remove the bay leaf and puree the soup using a regular or immersion blender. Check the seasoning and add the salt (you may need more or less depending on what type of stock you used). Ladle out the soup into individual bowls. Crumble some feta into each bowl, and drizzle each bowl with some of the zaatar oil.

We thought this was delicious, but with a few tweaks. I used the 2 lb. tub of precut sweet potatoes in the produce section at Trader Joe's and it was a perfect amount. I added 2 carrots instead of one, 2 large cloves of minced garlic, and a little Ras el Hanout. After it was blended, I added salt and pepper, but thought it could still use a little more depth of flavor and added some Better Than Bouillon for a boost. That flipped the trick! The oil and feta are a really nice touch. I think next time I make this, I'll swap the liquids and do 4 cups of stock and 2 cups of water instead. It's definitely an easy and tasty recipe, you just may have to adjust the seasoning to your own liking.

Don't sleep on this soup! Deceivingly simple, but this za'atar oil is a real hero. Amazing pre-thanksgiving food. Cozy, easy, tastes good.

BTW, left out the onion and leek due to dietary restriction. Threw in celery to add something to the pan to start. Still good.

Very tasty! When tasted by itself, the soup is nothing to write home about but with the feta and za'atar oil, it's delicious. I added pearl couscous for a bit of extra texture.

I am not a huge feta cheese fan, suggestions on substitute cheese?

Being as my grocery store only had giant sweet potatoes, I used about 4.5 pounds worth and the ratio was perfect (I also added an extra carrot.) I wanted a little more flavor, so I added some garam Masala, paprika and a little mixed seasoning from a spice shop. Incredibly hearty and delicious!

This is great - like, really great. I've made it a few times now, and I make some mall changes:
1. I add 2 cloves of garlic. I'm incorrigible like that - I'll add garlic to most things.
2. I'm huuuuuuge on spices, so I added some. I understand that not everyone is, but for those who are looking to add a little bit to the flavour profile (not that it needs it), The spices I use (in order of most to least) are: garam masala, ground coriander, cumin, caraway and smoked paprika
DELICIOUS. Thank you for the soup.

I enjoyed this soup a lot. Didn't have a leek at hand so I added extra onion and really caramelized it for all the flavor it could offer.

Excellent recipe. I used 5 cups of water rather than 6 to achieve a thick consistency, but not too thick.

Za'atar oil is not listed as an ingredient. How much is needed and where can it be bought? Same source as za'atar?

She means that you infuse 1/4 cup olive oil with 2 tablespoons of za'atar and let sit for an hour, then you have za'atar oil!

I love this site! Since this soup sounded fabulous I ran out and bought everything and made it. Much to my surprise, it was simply like too thick sweet potatoes that were pureed. Being an experienced chef, I tried doctoring this up and ended up throwing the entire pot away. Sad.

@julie B.
quite surprising that an experienced chef could not make this work and had to throw it away?!! thin it, add more bloomed spices, .wait- even with the feta and zaatar oil it was inedible?
sad

This soup is to die for. I ate it for a week straight for lunch. The za'atar oil is my new favorite thing to put on everything. Thanks for the recipe!

This is SO good...I made it with butternut squash. I went to a Mediterranean store and bought sumac and then made my own zaatar. I may burst ;)

me thinks that if you rave about this ingredient- zaatar- then you should mention its whereabouts! And the recipe includes 2 tablespoonfuls of zaatar yet there is discussion about zaatar oil? Are these two items meant to be the same thing?

totally agree, there is no such thing as a Middle East grocery story where I live. None. Nada.

This is delicious. The only change I made was to leave a few sweet potato chunks in the soup. Next time I will make twice as much zaatar oil (yuuumm).

Za'atar, oil where have you been my whole life?
I love Za'atar anyway, but this is a revelation. Made a leek and porcini ragu this week an d add a bit to the top, really great. Then had a ho-hum cauliflower soup, but zing-- za'atar oil, and it's a new soup. Can't wait to try it with this gorgeous Kuri squash that has this soup's name written all over it. Thanks for the inspiration!

This is the epitome of a dish that is super simple and straightforward to make, but exudes such thought and elegance that it seems like it should have taken hours to make. My husband is not a fan of feta, and he absolutely loved it in this dish. It is a really smart, crowd-pleasing dish and we loved it.

So, so good! This one has become a regular at our table. The potato soup base recipe is good on it's own but then when you add the zaatar and feta - it is totally over the top delicious!
