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.

  1. Preheat the oven to 350°F (175°C).

  2. Peel and thinly slice the potatoes.

  3. Peel and thinly slice the onions.

  4. Butter a baking dish.

  5. Layer the sliced potatoes and onions in the dish, seasoning with salt and pepper between layers.

  6. Repeat the layers until the dish is almost full.

  7. Cover the layers with milk or cream.

  8. Bake until the potatoes are tender and golden.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
