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

What each ingredient does

Eggs: Set when heated to form the custard that binds the omelet together.
Half and half: Adds moisture and a creamy texture to the set custard.
Sharp cheddar cheese: Melts into the custard, adding rich fat and savory flavor.
Ham: Provides the main savory, salty flavor and substance of the dish.
Onion: Adds aromatic sharpness that mellows as it bakes into the custard.

The step that matters

Reduce the oven temperature after 15 minutes. The high early heat sets and puffs the top. Dropping to 300°F then finishes the egg custard gently, so it stays tender instead of curdling, weeping or turning rubbery.

Swap the onion
