Directions
- 1
Season the steaks generously on both sides with salt and pepper. Heat the oil in a skillet over high heat and cook each steak 2–3 minutes per side to your preferred doneness.
- 2
Transfer the steaks to a plate and tent loosely with foil while you prepare the sauce — resting keeps them juicy.
- 3
In the same skillet over medium heat, sauté the onion rings until golden and tender, about 5 minutes. Add the garlic and cook for 1 minute more.
- 4
Pour in the water and scrape up all the browned bits from the bottom of the pan. Simmer for 3–4 minutes until the onions are very soft.
- 5
Remove from heat and stir in the mayonnaise until you have a smooth, creamy sauce.
- 6
Spoon the onion cream generously over the steaks and serve immediately with mashed potatoes, steamed rice, or crusty bread.
💡 Chef's Tip
Stir a teaspoon of Dijon mustard into the mayonnaise before adding it to the pan for extra depth. Never bring the sauce to a boil after adding mayo or it may split.
