Hasselback Potatoes

Method

1. 1
   • potato8

   Fan-cut the potatoes — Heat the oven to 220°C. Sit each potato in the bowl of a wooden spoon and slice down at 3-4 mm intervals: the spoon stops the knife before it cuts through, so the base stays intact and the slices fan open in the heat.

2. 2
   • potato8
   • butter60 g
   • olive oil2 tbsp
   • salt1 tsp
   • black pepper½ tsp

   Butter and season — Stir the olive oil into the melted butter. Brush half of it over the potatoes, working it down into the cuts, season generously with the salt and pepper, and set them cut side up in a roasting tin.

3. 3

   Roast until the slices open — Roast for 40 minutes, basting once halfway through with the buttery juices in the tin, until the slices have begun to fan open and the tips are colouring.

4. 4
   • butter60 g
   • olive oil2 tbsp
   • fresh thyme2 tsp
   • breadcrumbs40 g
   • Parmesan40 g

   Pack in the crumb topping — Mix the breadcrumbs, Parmesan and thyme leaves into the remaining butter and oil, then press the mixture down between the fanned slices and over the tops.

5. 5

   Crisp the crumbs — Return to the oven for 15-18 minutes, until the crumbs are deep gold and the outer slices shatter when tapped with a spoon; a skewer should slide into the base with no resistance.

   Rest before serving — Let them settle for 5 minutes out of the oven so the centres finish steaming, then serve straight from the tin.
