Scalloped Potatoes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Peel and thinly slice the raw potatoes.

Assemble

  1. Layer the potatoes in a baking dish, seasoning each layer with salt, pepper, and butter.

  2. Continue layering until the dish is full.

  3. Pour cream or milk over the top, then sprinkle with bread crumbs and add a small piece of butter.

Bake and serve

  1. Bake at 350°F (175°C) for one hour and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Raw potatoes
Form the bulk of the dish and soften into a tender, starchy body as they bake.
Cream or milk
Provides liquid that cooks into a creamy sauce around the potato slices.
Butter
Adds fat for richness and helps the top brown lightly in the oven.
Bread crumbs
Form a topping that adds texture and helps the surface brown.

The step that matters

Pour cream or milk over the top, then sprinkle with bread crumbs and add a small piece of butter.. The liquid needs to reach down between the layers so the potatoes cook evenly and the sauce thickens as starch releases. Adding it before the crumb topping and butter keeps the surface from drying out before the potatoes are tender.
