Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Beefsteak with Onion Sauce
Ingredients
Directions
Marinate
Marinate the steak in a mixture of sweet salad oil and vinegar, covering both sides.
Turn the steak over at bedtime.
Cook the steak
In the morning, heat a frying pan until hot enough to sizzle when the steak touches it.
Quickly brown the steak on both sides.
Reduce the heat and cook to desired doneness.
Fry the onions as directed in a separate recipe.
Once the steak is done, place it on a hot dish and season with salt and pepper to taste.
Make the sauce and serve
In the same pan, add the fried onions and their juices, then add enough hot water to make a semi-liquid sauce.
Break up the onions with a fork, season the sauce with salt and pepper, and pour it over the steak before serving hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Tender round cut that becomes the main protein, cooked to the desired doneness.
- Sweet salad oil
- Coats the surface during marinating and carries flavor into the meat while it sears.
- Vinegar
- Acidity in the marinade gently tenderizes the surface of the steak and adds tang.
- Onions
- Fried until soft and juicy, their juices and softened flesh form the body of the sauce.
The step that matters
Quickly brown the steak on both sides. The pan must be very hot so the surface browns quickly through the Maillard reaction, sealing in juices before the heat is lowered to finish cooking the interior.
Swap the onion
How well each one fits the dish's main ingredients (beef, vinegar, pepper):
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
- Mustardfits about as well
Fit is the average pairing score against beef, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
