Instructions

Prepare the vegetables

Preheat oven to 200 °C (400 °F). Toss sliced potatoes and diced winter vegetables with half the melted butter, salt, pepper, and minced garlic. Spread evenly in a greased 9‑inch baking dish.

Pro Tip: Arrange layers thinly; thicker pieces may stay undercooked.

Make the garlic‑cream sauce

In a saucepan, combine heavy cream, remaining butter, grated nutmeg, and a pinch of salt. Warm over low heat, stirring, until just simmering. Remove from heat and stir in half of the Gruyère until melted.

Pro Tip: Do not boil; high heat can cause the cream to separate.

Combine and bake

Pour the warm cream mixture over the layered vegetables, ensuring even coverage. Sprinkle the remaining Gruyère on top. Cover the dish with foil and bake for 25 minutes.

Pro Tip: Foil prevents premature browning while the interior cooks through.

Finish the crust

Remove foil and continue baking for another 15 minutes, or until the cheese is bubbling and the top turns a deep golden brown. Let the gratin rest 5 minutes before serving.

Pro Tip: A brief rest lets the sauce settle, making slicing cleaner.

Expert Tips

Tip #1: Uniform Slicing

Use a mandoline for potatoes to achieve consistent thickness; this guarantees even cooking and a smoother texture throughout the gratin.

Tip #2: Boost Flavor

Add a splash of dry white wine to the cream sauce before simmering; it brightens the garlic and adds subtle acidity.

Tip #3: Reheat Perfectly

When reheating leftovers, cover with foil and bake at 175 °C (350 °F) for 15 minutes, then uncover to restore the crisp top.

Storage & Variations

Cool the gratin completely, then refrigerate in an airtight container for up to 3 days. Reheat as described above. Swap Gruyère for smoked mozzarella for a richer flavor, or add sliced mushrooms for extra umami.

Yes. Replace half the heavy cream with whole milk or a plant‑based alternative (unsweetened oat or cashew cream). The texture will be slightly lighter but still delicious.
