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 ↓
Stuffed Onions
Ingredients
Directions
Prepare the filling
Scoop out the hearts of the onions and mince them very small.
Mince the beef and mix it with the minced onion, breadcrumbs, parsley, butter, salt, cayenne, and egg.
Stuff the mixture into the hollowed onions.
Stew and serve
Place the onions in a saucepan with the gravy and stew for three hours.
Thicken the sauce with a little flour and butter, adding more salt and pepper to taste.
Serve very hot with gravy poured around the onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Hollowed to hold the filling, and their softened flesh sweetens the gravy as they stew.
- Beef
- Provides the savoury meaty body of the stuffing.
- Breadcrumbs
- Absorb juices and help the filling hold together and stay moist.
- Egg
- Binds the stuffing so it holds its shape when cooked.
- Butter
- Adds richness and fat that carries flavour through the filling.
- Flour
- Thickens the gravy into a smooth sauce when cooked with butter.
The step that matters
Stewing the stuffed onions. A long, gentle stew lets the onions turn tender and sweet while the filling cooks through. Too fast a simmer can toughen the beef and dry the stuffing, so keep the liquid barely bubbling.
Swap the onion
How well each one fits the dish's main ingredients (beef, parsley, butter, egg, flour):
