Why it works: Onion and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Steak and Onions
Ingredients
Directions
Prepare
Peel and thinly slice the onions.
Heat the dripping in a large frying pan over medium heat.
Cook and serve
Add the onions, cover, and cook, stirring occasionally, until they are brown and moist.
Once the onions are done, lift them to the side of the dish.
Add the butter to the pan and fry the steak, turning with tongs until cooked.
Place the steak in the center of the dish and serve with a little butter on top.

What each ingredient does
- Onions
- Soften and release moisture, then brown and turn sweet as their sugars caramelize.
- Steak
- Provides the main protein and meaty flavor, browning on the hot pan surface.
- Butter
- Adds richness and a rounded, nutty flavor when fried and spooned on top.
- Dripping
- Conducts heat evenly in the pan and carries flavor to the onions.
The step that matters
Cooking the onions until brown and moist. Covering the pan traps steam so the onions soften and release their moisture, and stirring occasionally keeps them from scorching. Browning comes only after that moisture cooks off, so the sugars caramelize gradually and develop deep sweetness.
