Perfect Variations
Refine the basic recipe with aromatic herbs. Fresh thyme or rosemary give a Mediterranean note. For an autumnal version, mushrooms between the potato layers are suitable. Leeks create additional vegetable layers. For meat lovers, fried bacon pieces are a good match.
Optimal Potato Selection
Primarily waxy varieties like Yukon Gold or new potatoes are ideal. They retain their shape yet become tender. Starchy varieties break down too quickly. Don't pre-cook the potatoes - they cook perfectly in the cream-milk mixture.
Perfect Texture
For even cooking, cut the potato slices really thin - about 2-3 mm. A mandoline slicer or the slicing function of a food processor is ideal. The sauce should just cover the potatoes. Too little liquid leads to dry spots.
Storage and Reheating
The gratin keeps in the refrigerator for up to three days. When reheating, cover with aluminum foil and warm at 300°F to prevent drying out. For individual portions, the microwave is also suitable. Freezing is possible, but it tastes best fresh.

Serving Suggestions
The gratin is perfect as a side dish with roast beef or chicken. As a standalone dish, serve it with a crisp green salad. For a rustic dinner, homemade bread pairs well. A glass of white wine completes the taste experience.
