Ottolenghi’s Sweet Potato Chips

This summer I’m working my way through my most recent Ottolenghi cookbooks, Simple and Flavour, and finding quite a few classics to add to my repertoire. These sweet potato chips are a tasty, economical and quick to prepare and make a useful side dish or snack. Sweet potatoes store very well and are often cheaper per kilo than potatoes which is a bonus, especially during those months when only bland, tasteless potatoes are available. Sweet potatoes are not, however, a superfood, unless you need a huge injection of vitamin A. The superfood marketeers put this tuber in that mythical category. They are as healthy or unhealthy as a regular spud, depending on how you cook them. See the infographics pages here for more nutritional info.

Sweet Potato Chips, serves six to eight as a side.

I halved this recipe and still found we had rather too many. If you do cook the full amount, you may need more trays than suggested in this recipe, and two shelves, swapping half way through baking. The potatoes need to be placed in a single layer on the trays. Preheating the oven to 220º C guarantees successful baking in this short time frame. The potatoes can be prepared up to six hours ahead, up to the point of placing them in the oven.

  • sweet potatoes, 1.2 kg, peeled and sliced into 1½ cm thick chips. (see photos) 
  • 1 Tbsp sweet smoked paprika
  • ½ tsp cayenne pepper
  • 3 garlic cloves, crushed
  • 30 g polenta
  • 100 ml olive oil
  • 1 Tbls sumac
  • flaked sea salt
  1. Preheat the oven to 220ºc, fan on.
  2. Mix the sweet potatoes in a large bowl with the paprika, cayenne, polenta, oil and 1 teaspoon of flaked salt. Once combined, tip the sweet potatoes (and all the oil) on to two large parchment- lined baking trays and roast for 25-30 minutes, stirring gently once or twice, until the potatoes are cooked, crisp and golden brown.
  3. Remove from the oven, sprinkle over the sumac and 1 teaspoon of flaked salt, and serve at once.

  1. They look delicious… sweet and potato homemade wedges and chips are often on the menu here [last week under time pressure I bought a bag of frozen “pub style wedges” and was reminded why I make them myself] and I often premake a jars of flavoured salt but hadn’t thought of including polenta, and pre-making them ahead to deepen the flavour.

    1. I rarely make wedges. I’ve often been tempted by those supermarket versions, but know now not to succumb. Anything with smoked paprika on it is a winner for me- I’m obsessed with that Spanish smoky taste. The polenta adds crunch, the sumac adds mr ottolenghi.


  2. I’m so glad you’re working through these recipes – I have both books and although I enjoy them (particularly Flavour) from a ‘research’ perspective I find myself either put off by finicky ingredients or fusiony flavours I rarely crave. It’s a shame because I know there is gold in there – so I’m rapt you’re working to mine it for me 😀

    1. Yeah fusion things can be annoying, like sticking mango with soba noodles, or peach salad with furikake sprinkles….in Simple, ottolenghi leans towards easy classics but gives them a twist. Daisy is keen on his flavour bombs and is coming up here to make some jars for the beach.


  3. Have to smile as I basically eat Asian-Australian fusion food all the time and love fruit in cold soba noodle salads ! Truly vive la difference !! I find myself completely at home with fusion creations both Asian and European – the dishes often being created by what happens to be at home . . . . my big, big complaint always has been the fact that many people doing so retain the classic name as if they had the moral right to change an age-old dish ! As far as Ottolenghi is concerned . . . we seem to keep the same pantry and I rather enjoy ‘creating’ his way . . . Hmm !!! Potatoes I barely eat and tho’ sweet potatoes are also sweet on my menus . . . they rarely appear in the chip form . . . . yours do look tempting tho’ . . .

  4. Your Ottolenghi choices are really intriguing — I’m also working through his recipes, including my often-mentioned favorite of chicken with fennel and tangerines, which I made this week. I just love his spice chioices.

    be well… mae at

    1. Tangerines with chicken is a most unusual combination. The spice choices are interesting. I’m enjoying Simple as, to date, the recipes do sit well with our busy garden schedule. I’m yet to delve into flavour.


  5. oh yum these look so delicious! i adore sweet potato chips, and these look the bomb. i have never used an Ottolenghi recipe tho i know many many people love his books and recipes. I really must have a delve into them one day…
