Step 1

Preheat the oven to 180°C.

Step 2

Boil the beetroot in slightly salted water for 1½ hours, until the centre is soft.

Step 3

Make the sauce. Melt the butter in a medium saucepan, then add the flour, and stir to amalgamate the flour with the melted butter. Add the warm milk slowly, stirring constantly to avoid lumps, until the sauce is thick. Add 80g of the Parmesan, some nutmeg, chilli powder, salt and pepper to taste.

Step 4

Peel the cooked beetroot and cut into thin slices. In an ovenproof dish, build a layer of beetroot, followed by a layer of ham, then cover with some of the sauce. Build up these layers until you finish the ingredients, ending with the remainder of the sauce on top. Add a final sprinkle of the remaining Parmesan and black pepper.

Step 5

Bake in the preheated oven for 35 minutes and serve hot.
