Scalloped Eggs

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 350°F (175°C).
Butter a baking pan.

Assemble

Layer cracker crumbs on the bottom of the pan.
Add a layer of sliced hard‑boiled eggs.
Dot with butter and season with salt and pepper.
Repeat layers until the pan is full.
Pour milk over the top layer.

Bake

Bake for 30 minutes or until heated through.

What each ingredient does

Hard-boiled eggs: Form the main body of the dish and set into a soft, sliceable texture when heated.
Cracker crumbs: Add structure between layers and absorb some of the milk as the dish bakes.
Milk: Provides moisture that softens the crumbs and gives the baked dish a creamy texture.
Butter: Adds richness and fat that carries flavor and helps the top brown lightly.
