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

What each ingredient does

Eggs
Set into a firm, custard-like structure that holds the frittata together.
Parmesan cheese
Adds savory, salty flavor and helps the surface brown lightly as it cooks.
Milk
Adds moisture so the eggs stay tender rather than dry.
Red bell pepper
Adds sweetness and moisture as it softens in the butter and oil.
Onion
Adds savory depth as it softens into the egg mixture.
Butter
Adds richness and flavor to the skillet and the eggs.

The step that matters

Keep the heat low when the eggs go in. Eggs turn tough and rubbery when cooked too hot, so low heat lets the custard set gently and evenly. Lifting the edges lets runny egg flow underneath and cook through.

Swap the onion

How well each one fits the dish's main ingredients (egg, milk, parmesan cheese, pepper, butter, olive, thyme):
