How to Make Gratin Dauphinois

Step 1: Prepare the potatoes

Start by peeling your potatoes and slicing them thinly—about a quarter-inch thick is perfect. Using a mandoline slicer makes this easy and ensures uniform slices that cook evenly.

Step 2: Infuse the cream

Pour heavy cream into a saucepan and add crushed garlic cloves, a pinch of salt, pepper, and nutmeg if using. Warm the mixture gently on medium-low heat until you see steam and the flavors meld, but do not boil. This step allows the garlic and spices to fully infuse into the cream.

Step 3: Assemble the gratin

Butter a ceramic or glass baking dish generously to prevent sticking. Layer the potato slices neatly in overlapping rows. Pour the warm, infused cream evenly over the potatoes, making sure everything is well-coated. Dot bits of butter on top for an added golden finish.

Step 4: Add cheese and bake

Sprinkle grated Gruyère cheese evenly across the top. Place the dish in a preheated oven at 350°F (175°C) and bake uncovered for about 60 to 75 minutes. The gratin is done when the top is golden brown and bubbling, and the potatoes are tender when pierced with a fork.

Step 5: Rest before serving

Allow the Gratin Dauphinois to rest for about 10 minutes after baking. This resting period lets the dish settle, making it easier to cut and allowing flavors to fully develop.

Pro Tips for Making Gratin Dauphinois

• Slice potatoes evenly: Consistent thickness ensures even cooking and perfect texture.
• Use full-fat cream: It’s key to achieving that luxuriously creamy texture.
• Don’t rush the bake: Low and slow baking helps the potatoes absorb the cream fully without burning the cheese.
• Avoid boiling the cream: Heating gently preserves the delicate flavors and prevents curdling.
• Let the dish rest: Resting solidifies the layers and enhances cutability and taste.
