How to Make Potatoes Gratin
-
Preheat Oven: Start by preheating your oven to 350°F (180°C). This ensures it’s ready for that perfect bubbly finish.
-
Melt Butter: Melt the butter in a medium saucepan over medium heat. Add the finely diced onion and cook until tender, about 3-5 minutes, stirring occasionally.
-
Add Aromatics: Stir in the minced garlic and chopped thyme. Cook for about 1 minute, until fragrant, allowing those lovely aromas to fill your kitchen.
-
Incorporate Flour: Sprinkle in the flour, stirring constantly, and cook until it turns lightly golden, roughly 1 minute. This will be the base for your creamy sauce.
-
Make the Sauce: Gradually whisk in milk (or heavy cream), cooking until the sauce thickens for about 1-2 minutes. It should be pourable, yet thick enough to coat the back of a spoon.
-
Stir in Cheese: Remove from heat and fold in half of the shredded Gruyere cheese until melted. Season your sauce with a pinch of nutmeg, salt, and pepper to taste.
-
Layer the Dish: In a greased baking dish, spread a layer of the cheese sauce, then layer the sliced potatoes. Repeat this process until you run out of potatoes—ending with sauce on top. Sprinkle the remaining cheese generously over the top.
-
Bake: Place the dish in the preheated oven and bake for 45-60 minutes. You’re looking for tender potatoes and a beautifully golden-brown crust on top.
Optional: Garnish with fresh herbs before serving for an extra touch of color and flavor.

Potatoes Gratin Recipe FAQs
How do I choose the right potatoes for gratin?
Absolutely! For the best texture in your Potatoes Gratin, I recommend using russet or Yukon gold potatoes. They have a creamy consistency that melts beautifully in the oven. Look for potatoes that are firm with smooth skins, avoiding any with dark spots or blemishes.
How should I store leftover potatoes gratin?
To store leftover Potatoes Gratin, place it in an airtight container in the refrigerator. It will stay fresh for about 3 days. Simply reheat it in the oven to maintain its creamy goodness—cover it with foil to avoid drying out, and heat at 350°F (180°C) until warmed through.
Can I freeze potatoes gratin, and if so, how?
Very! To freeze your Potatoes Gratin, first allow it to cool completely. Then wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn.

What should I do if my sauce is too thin when making gratin?
If you find that your cheese sauce is too thin, don’t fret! You can thicken it by whisking in a bit more flour or cornstarch.

Cook for 1-2 more minutes to get rid of any raw flour taste.
