Ingredients

Why this recipe works

The method of shingling the potato slices is essential for the texture of this dish. By overlapping the slices, you create a structure that allows the garlic-infused cream to seep between the layers as they bake. This ensures that every single potato slice is thoroughly coated, resulting in a consistent, creamy texture throughout the entire casserole rather than a dry or unevenly cooked side dish.

Baking in two stages is the secret to a perfect scalloped potato. By covering the dish initially, you create a steamy environment that cooks the potatoes through until they are perfectly tender.

Removing the foil and adding the cheese for the final stage allows the top to become beautifully golden and bubbly without overcooking the potatoes or burning the dairy, providing a contrast between the soft interior and the savory, melted cheese crust.

Notes and substitutions

Russet potatoes are the ideal choice here because of their high starch content, which helps thicken the heavy cream sauce naturally as they bake. If you prefer a waxier texture, Yukon gold potatoes are a suitable alternative, though you may find the sauce remains slightly thinner.

Ensure that your slices are very thin, ideally around 1/8 inch, to guarantee they cook through within the specified time frame without becoming mushy.

The quality of the cheese makes a significant difference in the final result. Using freshly shredded sharp cheddar is highly recommended over pre-shredded varieties, which often contain anti-caking agents that prevent the cheese from melting into a smooth, cohesive layer.

If you find the sauce is too thick before baking, add a splash of milk to thin it, but keep in mind that the starch from the potatoes will naturally thicken the cream during the cooking process.

• russet potatoes: Yukon gold potatoes for a creamier, less starchy texture that holds its shape well when sliced thin.
• sharp cheddar: Gruyère or Monterey Jack for a different melt profile and flavor intensity.
