  • 1 lb potatoes, thinly sliced
  • 1 lb mushrooms, sliced
  • 1 onion, finely chopped
  • 2 cloves of garlic, minced
  • 1 cup grated cheese
  • 1 cup heavy cream
  • 2 tbsp butter
  • 2 tbsp olive oil
  • Salt and pepper to taste


1. Preheat the oven

Preheat your oven to 375°F (190°C).

2. Sauté the onions and garlic

In a pan, heat the olive oil over medium heat. Add the onions and garlic, and sauté until they are soft and translucent.

3. Add the mushrooms

Add the sliced mushrooms to the pan and cook until they are browned and any liquid they release has evaporated.

4. Layer the potatoes and mushroom mixture

Grease a baking dish with butter. Layer the thinly sliced potatoes in the bottom of the dish, followed by a layer of the mushroom mixture. Repeat until all the potatoes and mushrooms are used up.

5. Season and add cheese

Sprinkle salt and pepper over the layers. Pour the heavy cream over the top, and sprinkle the grated cheese evenly.

6. Bake

Cover the baking dish with foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15 minutes, or until the top is golden brown and the potatoes are cooked through.

7. Let it rest

Remove the gratin from the oven and let it rest for 10 minutes before serving.

8. Serve

Slice the gratin into portions and serve hot as a side dish or a main course.

9. Optional additions

You can customize this recipe by adding herbs like thyme or rosemary, or even a sprinkle of paprika for some extra flavor.

10. Enjoy!
