Potatisgratäng

Potatisgratäng is a creamy baked potato dish common in Swedish cuisine. It belongs to the family of gratins, where thinly sliced potatoes are layered with a dairy-based sauce and baked until tender. Typical ingredients are potatoes, heavy cream or a mix of cream and milk, butter, garlic, and grated cheese such as Gruyère, Emmental or cheddar. Some recipes include nutmeg or herbs; although cheese is common, some preparations omit cheese for a lighter version. Variants may use sour cream or yogurt to add tang, and vegan versions use plant-based milk and cheese.

Preparation involves slicing potatoes evenly, seasoning the slices, layering them in a dish with the sauce, and baking. The dish is often started covered to soften the potatoes, then uncovered to form a golden crust. Temperature normally around 180°C (350°F), with a total baking time of 60 to 90 minutes depending on potato thickness. The top may be finished with breadcrumbs or extra cheese for a browned crust.

Potatisgratäng is usually served as a side dish to roasted meat, poultry or fish, and can accompany vegetables or be part of a holiday dinner. It shares a clear link with French gratin dauphinois, though Swedish recipes vary in fat content and cheese usage. Variants include crisper tops, gluten-free versions with starch thickening, and regional adaptations.
