First I clean and wash the zucchini. Peel and wash the potatoes. The zucchini and potatoes I slice on a vegetable slicer or cut them into very thin slices with a knife. Peel the garlic.
I chop 1 clove of garlic and mix it with the cream. Season with salt, pepper and nutmeg. Grate the cheese.
Now I halve the 2nd clove of garlic and rub it into a tart or casserole dish (approx. 28 cm Ø). Then I grease the mould.
Layer zucchini and potato slices and half the cheese alternately in the mould. Pour the cream over it and sprinkle everything with the remaining cheese.
Bake the gratin in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 45 minutes. In the meantime, I cut the cooked ham into strips. Finally, I sprinkle the ham strips on the gratin and bake it at the same temperature for about 10 minutes more.
Then I'll make the gratin. Drink tip: dry white wine, for example Chardonnay.
