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

What each ingredient does

Eggs
Set when baked, binding the vegetables and cheese into a firm omelet.
Egg whites
Add structure and lightness, helping the omelet set firm without extra fat.
Potatoes
Add body and starch, giving the omelet a hearty, tender texture.
Mozzarella cheese
Melts through the eggs, adding richness and a stretchy, creamy texture.
Mushrooms
Release moisture and savory flavor as they cook, adding depth to the filling.
Onion
Sautéed until browned, adding sweetness and savory aroma to the base.

The step that matters

Sauté the vegetables until tender but not brown. Cooking the vegetables gently keeps them tender and releases moisture slowly. If they brown too much or are watery, the egg mixture can turn tough or soggy when baked.

Swap the potato
