How to Make Potato Gratin

Step 1: Prepare Potatoes

Start by peeling and slicing your potatoes evenly, about 1/8-inch thick, to ensure uniform cooking. A mandoline slicer is handy here but a sharp knife will work perfectly.

Step 2: Infuse Cream

In a saucepan, gently warm the heavy cream with peeled garlic cloves, fresh thyme sprigs, salt, and pepper. Let this mixture steep on low heat for 10 minutes to infuse flavors without boiling.

Step 3: Layer the Dish

Butter your baking dish generously, then arrange a layer of potato slices covering the bottom. Pour a few spoonfuls of the infused cream and sprinkle grated Gruyère on top. Repeat these layers until all potatoes and cream are used, finishing with cheese on top.

Step 4: Bake to Perfection

Cover the dish with foil and bake in a preheated oven at 350°F (175°C) for about 45 minutes. Remove the foil and continue baking another 25-30 minutes until the top turns golden brown and the potatoes are tender when pierced with a fork.

Step 5: Rest Before Serving

Let the Potato Gratin sit for 10-15 minutes after baking to set up perfectly. This resting period helps the layers stabilize, making it easier to slice and serve.

Pro Tips for Making Potato Gratin

• Uniform Slices: Consistent thickness ensures even cooking and perfect texture throughout.
• Don’t Rush the Cream Infusion: Letting the cream absorb garlic and herbs creates a deeper, balanced flavor.
• Butter the Dish Well: Prevent sticking and encourage a beautifully crispy bottom crust.
• Use a Mandoline: This tool helps achieve precision and saves prep time dramatically.
• Cover During Baking: Keeps the top from browning too quickly before the potatoes are tender inside.
• Let It Rest: Slicing too soon can cause the layers to fall apart; patience pays off.

How to Serve Potato Gratin

Garnishes

Freshly chopped parsley or chives add a pop of color and a fresh contrast to the rich, creamy layers. A light sprinkle of grated parmesan right before serving also amps up the cheesy goodness.

Side Dishes

Potato Gratin pairs beautifully with roasted meats like chicken or beef, crisp green salads, or steamed vegetables such as green beans or asparagus, rounding out a meal with complementary textures and flavors.

Creative Ways to Present

Try serving Potato Gratin in individual ramekins for an elegant touch at dinner parties. Alternatively, layer it in a clear casserole dish to showcase the gorgeous golden crust and creamy interior, making it as visually appealing as it is delicious.

Make Ahead and Storage

Storing Leftovers

Store any leftover Potato Gratin in an airtight container in the refrigerator for up to 3 days. Make sure to cover it tightly to prevent it from drying out or absorbing other fridge odors.

Freezing

Potato Gratin freezes well when wrapped securely in plastic wrap and foil. Freeze for up to 2 months but note that texture may slightly change; gentle reheating helps restore creaminess.

Reheating

Reheat leftovers in a 325°F (160°C) oven covered with foil to avoid drying, until warmed through. For a crispy top, uncover during the last 10 minutes of heating.
