Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Broiled Beefsteak with Onions
Ingredients
Directions
Prepare the onions
Peel and wash the onions, then slice them.
Place the sliced onions in a skillet with enough water to cover and boil until tender.
Drain the water, add 2 tablespoons of butter, and fry the onions until they are nicely browned.
Keep the fried onions warm on the side of the stove.
Cook and serve the steak
Broil the beef steak until cooked to your liking.
Remove the bone from the steak, then scatter bits of butter, salt, and pepper over it.
Top the steak with the fried onions before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the main protein, which firms and browns as it cooks under the broiler.
- Onions
- Boiling then frying softens them and browns their natural sugars for sweetness and depth.
- Butter
- Adds fat for frying the onions and enriches the steak with flavour and richness.
The step that matters
Frying the onions until nicely browned. Boiling first softens the onions, but browning needs dry, hot contact with fat. Drain well so the onions fry rather than steam, letting their sugars caramelise for sweetness.
Swap the onion
How well each one fits the dish's main ingredients (beef, butter, pepper):
- Potatofits about as well

- Capsicumfits about as well
- Tomatofits about as well
Fit is the average pairing score against beef, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
