Here’s a complete guide to Au Gratin Potatoes, a creamy, cheesy potato dish perfect as a side for dinner:
Au Gratin Potatoes Overview
Au Gratin Potatoes (or “Potatoes au Gratin”) are thinly sliced potatoes baked in a rich, creamy cheese sauce until golden and bubbling. Unlike scalloped potatoes, au gratin typically includes cheese both in the sauce and on top.
- Texture: Tender potato slices with a creamy interior and golden, slightly crispy top
- Flavor: Rich, cheesy, buttery, and comforting
- Servings: 4–6
Ingredients
- 2 lbs (900 g) potatoes, peeled and thinly sliced
- 2 cups (480 ml) heavy cream or milk
- 1 1/2 cups shredded cheese (cheddar, Gruyère, or a mix)
- 2 tbsp butter
- 2 tbsp all-purpose flour
- 1 small onion, finely chopped (optional)
- 1 clove garlic, minced
- Salt and pepper to taste
- Optional: paprika or nutmeg for extra flavor
Instructions
1. Preheat Oven
- Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
2. Make the Cheese Sauce
- Melt butter in a saucepan over medium heat.
- Add onions and garlic; sauté until soft.
- Stir in flour and cook 1–2 minutes to form a roux.
- Slowly whisk in cream or milk until smooth and thickened.
- Add 1 cup of cheese, stirring until melted. Season with salt, pepper, and optional spices.
3. Assemble the Dish
- Arrange half of the sliced potatoes in the baking dish.
- Pour half of the cheese sauce over the potatoes.
- Layer the remaining potatoes and top with the rest of the sauce.
- Sprinkle remaining cheese over the top for a golden crust.
4. Bake
- Cover with foil and bake 45 minutes.
- Remove foil and bake another 15–20 minutes until the top is golden and bubbly.
5. Serve
- Let rest 5–10 minutes before serving so the sauce thickens slightly.
Tips for Perfect Au Gratin Potatoes
- Slice potatoes thinly: Use a mandoline for even cooking.
- Partially cook potatoes: Parboil or microwave for 5 minutes if you want faster baking.
- Cheese choice: Gruyère gives a nutty flavor; sharp cheddar adds tang.
- Make ahead: Assemble the dish and refrigerate; bake when ready.
💡 Serving Ideas:
- Perfect with roasted meats, chicken, or ham
