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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the body of the soup and absorbs broth, giving it a starchy, substantial texture.
- Butter
- Adds fat that carries flavor and gives the soup a richer mouthfeel.
- Onion
- Softens as it cooks and contributes savory, aromatic sweetness to the broth.
- Broth
- Provides the main liquid and the base savory flavor of the soup.
- Parmesan cheese
- Adds salty, savory depth and a sharp, nutty flavor at the end.
The step that matters
Simmering the macaroni in the broth. Pasta keeps softening and absorbing liquid while it sits in hot broth, so extended simmering makes it mushy and prone to breaking apart. Checking it often and stopping once it is just tender keeps its shape.
Swap the onion
