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

What each ingredient does

Eggs: Set into a custard that holds the omelet together as it bakes.
Half and half: Adds moisture and richness, keeping the custard tender rather than dry.
Breakfast sausage: Provides fat and savory flavor that seasons the whole dish as it bakes.
Fontina cheese: Melts into the custard, adding creaminess and a rich, savory flavor.

The step that matters

Bake at 425°F, then lower to 300°F. The high start sets the custard edges, while the lower temperature cooks the center gently. Staying at high heat too long can overcook the eggs, making them rubbery and watery.

Swap the onion
