Ingredients
- 4 large potatoes, thinly sliced
- 2 cups mushrooms, sliced
- 1 package (5.2 oz) Boursin cheese
- 1 cup heavy cream
- 1 cup shredded cheese (e.g., Gruyère)
Instructions
- Preheat the oven to 375°F (190°C) and generously butter a 9x13 inch baking dish to prevent sticking.
- Wash and thinly slice potatoes using a mandoline or sharp knife, ensuring uniform thickness of approximately 1/8 inch for even cooking.
- Clean and slice mushrooms into uniform thin pieces, removing any tough stems.
- In a large mixing bowl, combine heavy cream, crumbled Boursin cheese, and whisk until smooth and well-integrated.
- Layer the bottom of the baking dish with a thin layer of sliced potatoes, slightly overlapping each slice to create an even base.
- Distribute half of the sliced mushrooms evenly over the potato layer.
- Pour half of the cream and Boursin mixture over the potatoes and mushrooms, ensuring even coverage.
- Repeat layering with remaining potatoes, mushrooms, and cream mixture.
- Sprinkle shredded Gruyère cheese over the top layer, covering the entire surface.
- Cover the baking dish with aluminum foil and bake for 30 minutes.
- Remove foil and continue baking for an additional 15 minutes until the top is golden brown and potatoes are tender when pierced with a fork.
- Let the dish rest for 10 minutes after removing from the oven to allow flavors to settle and sauce to thicken.
- Serve hot, garnishing with fresh chopped parsley or chives if desired.
Tips
- Slice Consistently: Use a mandoline or sharp knife to ensure uniform potato thickness, which guarantees even cooking and a professional presentation.
- Cheese Selection Matters: While Gruyère is recommended, feel free to experiment with other melting cheeses like Emmental or sharp cheddar for unique flavor profiles.
- Prevent Sticking: Generously butter your baking dish and consider using parchment paper for easier cleanup and perfect release.
- Don't Rush the Resting: Allowing the dish to rest for 10 minutes after baking helps the sauce thicken and makes serving easier.
- Fresh Herbs are Optional but Recommended: A sprinkle of fresh parsley or chives can add a bright, fresh contrast to the rich, creamy dish.
- Temperature Control: Keep an eye on your oven to prevent over-browning. If the top is getting too dark before potatoes are tender, cover with foil.
