What each ingredient does
- Beef steak
- Is the main protein, cooked to provide the meat and savory flavor of the dish.
- Onions
- Browning in fat develops sweetness and deep savory flavor, and they add texture on top of the steak.
- Beef drippings or butter
- Fat for frying that carries heat evenly and helps the onions brown.
The step that matters
Browning the onions. Onions need enough heat and fat to brown rather than steam. Browning caramelizes their natural sugars, which gives sweetness and depth. Crowding the pan or using low heat makes them pale and soggy.
