What each ingredient does
- Beef steak
- Provides the main protein, which browns on the outside and stays juicy when cooked.
- Onions
- Browning in fat develops sweetness and savory flavor, adding a rich topping to the steak.
- Beef drippings or butter
- Fat that conducts heat for frying the onions and adds rich flavor.
The step that matters
Frying the onions until brown. Onions need enough heat and time for their natural sugars to caramelize and turn brown. Stopping early leaves them pale, raw-tasting, and less sweet, while overheating can scorch them and make them bitter.
