Recipe Information
Ingredients
- 1000 g Potatoes
- 300 g Mushrooms (button or cremini, sliced)
- 2 cloves Garlic (minced)
- 30 g Unsalted butter
- 1 tbsp Olive oil
- 200 ml Heavy cream
- 100 ml Whole milk
- 120 g Gruyère cheese (grated)
- 1 tsp Fresh thyme leaves
- 1 tsp Salt
- 0.5 tsp Black pepper
- 0.25 tsp Nutmeg (freshly grated, optional)
Instructions
Preheat your oven to 180°C (350°F). Grease a medium-sized baking dish with a bit of butter or olive oil and set aside.
Peel the potatoes and slice them thinly (about 3-4 mm thick) using a sharp knife or mandoline for even cooking.
Heat the butter and olive oil together in a large skillet over medium heat. Add the sliced mushrooms and a pinch of salt, cooking until the mushrooms are softened and any released liquid has evaporated (about 5-7 minutes). Stir in the minced garlic and thyme leaves, cooking for another minute. Remove from heat and set aside.
In a medium saucepan, combine the heavy cream, milk, salt, pepper, and nutmeg (if using). Heat gently over low-medium heat until just warmed through. Do not let it boil.
Begin assembling the gratin by spreading a single layer of potato slices across the base of the prepared baking dish. Top with a layer of the sautéed mushrooms, then sprinkle a small amount of grated Gruyère cheese over the mushrooms.
Repeat the layering (potatoes, mushrooms, cheese) until all the ingredients are used up, finishing with a final layer of potatoes on top.
Pour the warm cream and milk mixture evenly over the layered potatoes and mushrooms. Gently press down on the top layer with a spatula to ensure all the potatoes are coated in the liquid.
Sprinkle the remaining Gruyère cheese over the top layer of potatoes for a golden, cheesy crust.
Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes. Then remove the foil and bake for an additional 20 minutes, or until the top is bubbling and golden and the potatoes are fork-tender.
Let the gratin rest for 5-10 minutes before serving. Garnish with a few extra thyme leaves if desired, and serve warm alongside a crisp green salad or roast meat for a complete meal.
