Make yourself the ultimate savoury snack: sweet potato crisps. These crunchy, golden rounds roasted in a fiery spiced oil are easier than you might think.


Sweet potato, raw

150 g

Sunflower Oil

2 teaspoon(s)

Cajun seasoning

2 teaspoon(s)


  1. Preheat the oven to 150°C, fan 130°C, gas mark 2. Line two baking trays with baking paper.
  2. Scrub the sweet potato clean, and dry thoroughly. Using a mandoline or a very sharp knife, carefully slice the potato into thin rounds about 2mm thick. Put the slices into a large bowl.
  3. In a small bowl, combine the oil and seasoning. Drizzle over the sweet potato slices and toss everything together with your hands until evenly coated. Season with salt and toss again.
  4. Arrange the sweet potato slices on the baking trays in a single layer. Bake for 35-40 minutes, turning the crisps and rotating the trays halfway through, until golden and crisp. Keep an eye on the rounds for the final 5 minutes of baking to make sure they don’t burn. If they are not quite crisp enough, continue to bake, checking them every few minutes until they are done.
  5. Remove from the oven and set aside for 10 minutes to cool completely, then serve.
