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 ↓
Beef Loaf
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make and shape the loaf
In a large bowl, combine the ground beef, egg, chopped onion, and bread crumbs or crushed crackers.
Mix well until all ingredients are evenly incorporated.
Shape the mixture into a loaf and place it in a baking dish.
Bake
Bake for about 1 hour or until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the main body and rich flavor of the loaf.
- Egg
- Binds the meat and helps the loaf hold its shape as it sets.
- Bread crumbs or finely crushed crackers
- Absorbs juices and keeps the loaf tender and moist while baking.
- Onion
- Adds moisture and savory flavor throughout the loaf.
The step that matters
Mix until evenly incorporated. Mixing just until combined keeps the loaf tender. Overworking ground meat develops proteins that make it dense and firm.
Swap the onion
How well each one fits the dish's main ingredients (beef, egg, bread):
- Asparagusfits better
- Tomatofits better
- Leekfits about as well
- Onionthe original
Fit is the average pairing score against beef, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
