Sweet Potato Chips and Avocado Mayo


Food writer Lucy Jessop creates a delicious avocado mayo to sink your sweet potato chips into. Genius!

Ingredients (serves 4)
For the sweet potato chips

  • 4 sweet potatoes (about 800g)

  • 3 tablespoons olive oil

  • 3 tablespoons polenta

  • 1 teaspoon paprika

  • Sea salt

For the mayo

  • 1 large ripe avocado

  • 40g root ginger, peeled and finely grated

  • ½ small garlic clove, crushed

  • 3 tablespoons lime juice

  • Zest of 1 lime

  • Dash of Tabasco (optional)

  • 1 tablespoon olive oil


  1. Preheat the oven to 200°C/fan 180°C/gas mark 6. Wash the sweet potatoes in cold water and dry thoroughly with a clean tea-towel – there’s no need to peel them. Cut lengthways into 1cm wide chips.

  2. Transfer to a large bowl. Add the olive oil and toss to coat. Then add the polenta, paprika and a good pinch of salt. Mix well to evenly coat.

  3. Spread the chips between two large roasting tins. They need as much space as possible, so they should be in a single layer. Bake for 35–40 minutes until tender and crisp.

  4. Meanwhile, make the ‘mayo’ dip. Place the avocado flesh in a food processor. Add the grated ginger, garlic, lime juice and zest, Tabasco (if using), olive oil, 1 tablespoon of cold water and a large pinch of salt. Whizz until smooth. Transfer to a small dish and serve with the warm, crunchy sweet potato chips.
