Onion and Macaroni Omelet

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

  2. Stew the onions in a dish with the butter until tender.

  3. Boil the macaroni in water for about 30 minutes; drain and cool, then cut into pieces.

  4. Mix the bread crumbs with the milk; add the beaten eggs, pepper, and salt.

Assemble and bake

  1. Place the onions in a well-buttered dish dusted with flour, layer the macaroni on top, and pour in the egg mixture.

  2. Bake until set, then turn out onto a hot flat dish and serve with brown sauce.

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

What each ingredient does

Eggs
Set the custard-like mixture so the omelette holds its shape when baked.
Bread crumbs
Absorb the milk and eggs, giving the omelette body and a soft, tender texture.
Milk
Adds moisture that bakes into the egg mixture, keeping the omelette tender.
Butter
Adds richness and flavour and helps the onions soften and brown gently.
Macaroni
Provides a firm, chewy layer that gives the dish its structure and bite.

The step that matters

Bake until set. Eggs set as their proteins coagulate with heat; pulling the dish too early leaves a runny centre, while overbaking makes the eggs rubbery and dry.

Swap the onion

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

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

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