Chronicles of Gratin Dauphinois
The origins of Gratin Dauphinois trace back to at least 1788 when it was first documented at a banquet. However, this simple yet refined dish had been a staple long before then. The Dauphiné region of France, due to its proximity to Switzerland, was introduced to potatoes earlier than much of the country—well before Antoine Parmentier helped popularize them in French cuisine.
Traditionally a humble peasant dish, Gratin Dauphinois consists of thinly sliced potatoes, milk, and garlic, slowly baked to perfection. The starch from the potatoes, combined with butter, naturally forms a golden, crispy crust—hence the term au gratin.
Over time, the recipe evolved, incorporating rich additions like cream, cheese, and nutmeg. The word gratin itself comes from the French verb gratter, meaning “to scrape,” referring to the delicious crispy bits that form at the bottom and edges of the dish.

Step-by-step: How to Make Potato Au Gratin
Step 1: Preparing the Ingredients -Mise en Place

Wash, peel, and thinly slice the potatoes using a sharp knife or mandoline slicer (pic. 1 and pic. 2)

Heat the milk and cream in a pot, adding smashed garlic (pic. 3) , thyme, and coarsely crushed black pepper (pic. 4). Let it simmer to infuse the flavors, then strain and set aside.
Shred the cheese. Mix the salt and black pepper in a small bowl and set aside
Lay the slices on a clean kitchen towel to remove excess moisture, keeping the starch intact.
Set aside the best-looking slices for the final top layer.
Step 2: Layering the potatoes

Generously butter an ovenproof gratin dish and sprinkle with parmesan cheese (pic. 5).
Start by arranging the potato slices around the perimeter of the dish, slightly overlapping them (pic. 6).
After the first layer, season with salt and pepper, then sprinkle with ¼ cup of cheese.

Continue layering, seasoning each layer, and adding cheese (pic. 7).
For the final layer, arrange the reserved slices neatly for an elegant presentation.

Pour the infused cream mixture evenly over the potatoes (pic. 8 & 9) and top with the remaining cheese (pic. 10).
Dot with butter and add extra cheese if desired for a crispier crust.
Step 3: Baking the potato gratin
Preheat the oven to 325°F (160°C).
Bake for 1 to 1½ hours, or until the potatoes are soft and the top is golden brown and crispy.
Check for doneness at the 1-hour mark by sliding a knife through the layers.
If needed, increase the temperature to 350°F (180°C) for the last few minutes to enhance browning.
Best Ways to Serve Gratin Dauphinois
