Cooking Instructions
1.
Preheat the oven to 180°C/160°C fan. Spread a little
bechamel sauce (1 jar)
over the bottom of a gratin dish or baking tray.
2.
Arrange a layer of
sweet potatoes (3)
at the base of the dish, scatter with some
beans (1 tin)
and
rosemary (1 handful)
and season. Spoon over some of the béchamel and repeat the process, alternating sweet potato, beans, rosemary and béchamel, finishing with a layer of sweet potato, but leaving some béchamel in the jar.
3.
Cover with the remaining béchamel, then scatter over the
breadcrumbs (75 g)
and the reserved chopped rosemary. Bake in the oven for 1 hour or so, until the breadcrumbs are golden and the sweet potato is tender when a knife is stuck in. Leave to cool for a few minutes, then serve with steamed green vegetables, if you like.
