Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Savoury Omelet
Ingredients
Directions
In a bowl, beat the eggs until well mixed.
Add the chopped pepper, salt, thyme, parsley, and optional onion or shallot.
Heat a non-stick skillet over medium heat and pour in the egg mixture.
Cook until the edges set, then gently lift the edges to allow uncooked egg to flow underneath.
Once mostly set, fold the omelet in half and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelet as they cook, holding the filling together.
- Parsley
- Adds fresh, green aroma and a light herbal flavour to the eggs.
- Dried thyme
- Adds earthy, herbal aroma that complements the eggs.
The step that matters
Cook until the edges set, then lift to let uncooked egg flow underneath. Cooking over medium heat and lifting the edges lets the eggs set gently into a tender layer. If the heat is too high, the proteins tighten quickly and the omelet turns rubbery and browned instead of soft.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (egg, pepper, thyme, parsley):
- Shallotfits better
- Carrotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, thyme, parsley. Candidates are from the same food group and used in at least 100 recipes.
