Instructions
Prepare Potatoes
Start by peeling and thinly slicing the potatoes — aim for slices about ⅛ inch thick. You can use a mandoline slicer for perfect, even layers.
To remove excess starch and help them cook evenly, soak the slices in cold water for 5 minutes, then rinse and drain well. This little trick keeps your gratin tender and prevents the layers from sticking together.
Make Gratin Sauce Without Cream
In a medium pan over low heat, melt butter and stir in all-purpose flour. Cook for 1–2 minutes until it turns slightly golden and smells nutty — this helps remove the raw flour taste.
Slowly pour in milk, whisking constantly to keep the sauce silky smooth (no lumps allowed!).
Once it thickens slightly, season with salt, black pepper, and a pinch of paprika for a gentle warmth. Keep stirring until your sauce looks creamy and glossy — that’s your perfect cream-free gratin base.
Layer The Gratin
Grease a baking dish with butter or oil. Arrange a layer of sliced potatoes, pour some of the sauce evenly over them, and sprinkle a generous handful of shredded cheese (Gruyère, cheddar, or mozzarella all work beautifully).
Repeat the layering process until all the potatoes and sauce are used — finishing with a cheesy top layer. Cover the dish tightly with aluminum foil to help the potatoes steam and soften during baking.
Bake
Place your dish in a preheated oven at 220°C (428°F) and bake for 1 hour or until the potatoes are tender when pierced with a knife.
Broil For Signature Golden Top
Remove the foil carefully and sprinkle a final layer of mozzarella or your favorite melting cheese on top.
Switch the oven to broil (or bake from the top) for about 5 minutes, until the surface turns beautifully golden, bubbly, and crisp — the hallmark of a perfect au gratin!
Serve
Let it rest for 5–10 minutes before serving — this helps the layers set and makes slicing easier. Serve warm as a side for roast chicken, beef, or your favorite main dish, and get ready for everyone to ask for seconds!

Notes
Here are a few tips and tricks for beginners trying au gratin at home:
Best Cheese for Gratin: Cheese is the star of any gratin — it adds flavor, creaminess, and that irresistible golden crust. Traditional recipes call for Gruyère, but it can be expensive. I love using a mix of cheddar and mozzarella — they melt beautifully, brown evenly, and give a rich, cheesy taste at a fraction of the cost.
Ideal Baking Dish: Choose a shallow baking dish to ensure even cooking and a beautifully browned top. An 11 x 7-inch dish works perfectly, but feel free to use whatever you have — just remember that deeper dishes may need a slightly longer baking time.
Best Potatoes to Use: Use starchy or all-purpose potatoes (like Yukon Gold or Desiree) for the creamiest, most flavorful gratin. They hold their shape but become tender and melt-in-your-mouth after baking.
Cream Alternatives: If you’re skipping cream, full-fat milk is your best friend. It gives a smooth, silky sauce that keeps your gratin rich without being heavy.
Don’t Overpour the Sauce: Pour just enough sauce to coat the potato layers. Too much will make the gratin runny and watery after baking.
Dry the Potatoes: Before layering, make sure the potato slices are well-drained and patted dry. Wet or watery potatoes can make the dish soggy and prevent a crisp top.
Wrapping & Broiling: Cover the dish with foil during the first part of baking. After 1 hour, remove the foil, top with mozzarella or your favorite melting cheese, and broil for a few minutes. This gives the gratin its signature golden, bubbly, au gratin finish.
