Why it works: Onion and beef 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 ↓
Beefsteak and Onions
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Brown the onions
Dredge sliced onions in flour and fry until slightly browned.
Braise the beef
Transfer onions to a pot with the beef, add salt, pepper, and boiling water to half cover the beef.
Cover the pot and bring to a brisk boil, then reduce heat to simmer gently for 1 to 2 hours.
Alternatively, cover the pot tightly and place it in a 350°F (175°C) oven for the same time, turning the meat once.
Add boiling water if the gravy evaporates too quickly.
Serve
Serve the beefsteak topped with the onions and pour the gravy over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Long, slow cooking breaks down its connective tissue, making the meat tender.
- Onions
- Browning in butter builds sweetness and savory flavor, which then enriches the gravy.
- Flour
- Coating the onions lets the flour thicken the cooking liquid into a gravy.
- Butter
- Fat for frying carries heat evenly and helps the onions brown.
The step that matters
Simmer gently after the initial boil. A hard, rolling boil for the full cooking time toughens muscle fibers and evaporates the liquid quickly. A gentle simmer keeps the beef tender and the gravy from reducing too far.
