Escalloped Onions

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 the onions

  1. Slice the onions and boil them until tender.

Assemble and bake

  1. Layer the onions in a baking dish, adding bread crumbs, butter, pepper, and salt between each layer until the dish is nearly full.

  2. Cover the top with bread crumbs and pour in milk or cream until the dish is full.

  3. Bake at 350°F (175°C) for 30 minutes or until the onions are tender.

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

What each ingredient does

Onions
Form the bulk of the dish and soften into a sweet, tender base as they cook.
Bread crumbs
Soak up liquid and add body, helping the layers hold together while baking.
Butter
Adds richness and moisture, and helps the top crumbs brown in the oven.
Milk or cream
Provides the liquid that moistens the layers and sets into a soft, custard-like texture.

The step that matters

Pour in the milk or cream until the dish is full. Too little liquid leaves the crumbs dry and the onions stiff, while the liquid needs to reach the layers to moisten them evenly as the dish bakes.

Swap the onion

How well each one fits the dish's main ingredients (bread, butter, pepper, milk):

  1. Capsicumfits better
  2. Potatofits better
  3. Tomatofits better
  4. Onionthe original

Fit is the average pairing score against bread, butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
