Turn the oven on to 200°C (thermostat 6 to 7) so it's nice and hot when it's time to brown the gratin.
Tip · For a creamier gratin, you can add a little milk to the cream, just don't thin it out too much so it stays rich and smooth.
Peel the vegetables
Peel the zucchini and potatoes, then cut them into thin rounds (about 3 mm) so they cook evenly.
Tip · To keep the potatoes from sticking to the skillet, don't pile them up and stir regularly while they cook.
Sauté the vegetables
Heat the olive oil in a nonstick skillet over medium heat. Add the zucchini and potatoes, then season lightly with salt and pepper. Sauté for 5 min, stirring now and then.
Make the cream
In a bowl, mix the crème fraîche with the nutmeg and a pinch of salt and pepper. Set aside.
Layer in a dish
In an ovenproof dish (or an ovenproof skillet), spread a layer of vegetables, spoon over half the cream, then add the rest of the vegetables. Finish with the rest of the cream.
Add the cheese
Scatter the shredded cheese evenly over the top for a nice golden crust.
Bake the gratin
Put the dish in the preheated oven and bake for 15 min until the top is nicely golden and the vegetables are tender.
