Instructions Let’s bring this luxurious gratin to life:
Preheat and Prep: Preheat your oven to 375°F (190°C). Grease a baking dish to prevent sticking.
Sauté the Mushrooms: Heat olive oil in a pan over medium heat. Add the sliced mushrooms, season with salt and pepper, and cook until soft and golden brown. Set aside.
Prepare the Cream Mixture: In a small saucepan, heat the heavy cream with pressed garlic over low heat. Stir occasionally until warm but not boiling.
Layer the Gratin: Arrange a layer of thinly sliced potatoes in the greased baking dish. Top with a portion of the sautéed mushrooms and crumbled Gorgonzola. Repeat the layers until all ingredients are used.
Pour the Cream: Evenly distribute the warm cream mixture over the layered potatoes and mushrooms.
Add the Final Touch: Sprinkle grated Gruyère cheese on top for an irresistible golden crust.
Bake to Perfection: Cover with foil and bake for 40 minutes. Remove the foil and bake for another 15-20 minutes, or until the top is golden and bubbly.
Let It Rest & Serve: Allow the gratin to cool for a few minutes before serving. This helps the layers set and enhances the flavors.
