📝Key Ingredients For Authentic French Potatoes Au Gratin

Just 4 Ingredients

• Waxy potatoes: They hold their shape and create that signature layered texture.
• Heavy cream: Gives the gratin its luxurious silkiness.
• Garlic: Infuses the cream and potatoes with gentle warmth.
• Nutmeg: Just a pinch adds depth to the flavor of the dish.
• Butter: For greasing the dish so nothing sticks and the edges caramelize.

Substitutions

• Swap half the cream for whole milk if you prefer a lighter texture.
• Add a tiny sprinkle of cheese on top, but traditionally, this dish is cheese-free.
• Infuse the cream with thyme or bay leaf for a subtle herbal note.

🔢 How To Make Authentic French Potatoes Au Gratin

Step 1

Preheat your oven to 325°F. Butter a medium baking dish generously so the potatoes release easily and the edges brown beautifully.

Step 2

Peel the potatoes and slice them very thinly, about ⅛ inch. Consistent slices help the gratin dauphinois recipe cook evenly. Use a mandoline for this if you have one. Otherwise, slice as evenly as you are able.

Step 3

Rub one cut garlic clove all over the inside of the dish, then mince or crush the rest. Layer the potatoes neatly in the dish, overlapping slightly like shingles on a roof.

Sprinkle each layer lightly with salt, pepper, some garlic, and a tiny pinch of nutmeg.

Pour the cream evenly over the potatoes. It should just come up to the top layer without drowning them. (The photo only shows half the cream.)

Alternatively, for a creamier and lower-fat content potato dish, make my béchamel sauce, and pour the sauce over the layered potatoes.

Step 4

Bake for about 1 hour, longer if needed, or until the potatoes are tender and the top is golden with little caramelized edges.

Baking Tip 1: To bake Gratin Dauphinois well, a heavy-bottom baking dish is the best. Thick glass like Pyrex, Corningware, cast iron, or stoneware are all good choices that will allow the potatoes to cook to a nice softness without burning.

Baking Tip 2: For a firmer gratin, bake uncovered the entire time. For a softer one, cover for the first half.

Step 5

Let the gratin rest for 10 minutes before serving so the layers settle into that perfect creamy texture.

What To Serve With This Recipe

• Serve with your chosen meat, such as Ham Ficelle Picarde Recipe, or French Sausage Recipe.
• A Green Leafy Salad, Salad With Artichokes, or Salade Lyonnaise Recette.
• It's good on its own too when you feel in the need of comfort eating, especially with a glass of wine and some crusty French bread.

What Else Can Be Created From The Humble Potato?

Potatoes are one of our little friends in the kitchen - they are inexpensive, even more so if you can grow your own, and yet they make the most wonderful dishes from pommes frites (chips or fries to some of us) to boulangére potato recipe, potato fondant, and in this instance, the beautiful gratin dauphinois.

🔄 Variations

• If you include cheese with this dish, then strictly speaking, that would be Gratin Savoyard. Use comté cheese or gruyère; they are delicious and look lovely when cooked.
• Alternatively, for a creamier and lower-fat content potato dish, make my béchamel sauce, and in step 8, pour the sauce over the layered potatoes.
