Potato-celeriac gratin

Preheat the oven to 175 ° C.

Peel the potatoes and celeriac and scrape thin slices with a cheese slicer.

You can also cut them as thin as possible. Do you have a food processor. Then you can also plan them in thin slices.

Peel the garlic and cut finely. Ris the leaves of the sprigs of thyme, mix with the celeriac and potato slices and spread over the greased oven dish.

Pour the cream over the vegetable and potato slices and sprinkle with the cheese.

Place the rest of the sprigs of thyme on them and fry the gratin until golden brown and cooked for about 1 hour under the center of the oven.

Cover after 30 min loosely with aluminum foil so that the top is not too dark.
