Steak and Onions
Ingredients
Directions
Prepare the onions
Fry the onions in one pan until golden brown.
Cook the steak
In another pan, cook the steak to your desired doneness.
If using the same pan, brown the steak briefly, then remove excess fat.
Braise and finish
Layer half the fried onions in the pan, place the steak on top, and cover with the remaining onions.
Add stock, season with salt and pepper, and simmer gently for about an hour.

What each ingredient does
- Steak
- Provides the main protein, which firms as it cooks and becomes tender with gentle simmering.
- Onions
- Browning builds sweetness and savory depth, and they soften into the sauce during simmering.
- Stock
- Supplies liquid for gentle simmering and carries flavor into the pan juices.
The step that matters
Browning the onions until golden. Slow frying lets sugars caramelize and the Maillard reaction develop deep flavor. Pale or underbrowned onions give a flat, watery-tasting dish.
