Why it works: Garlic and onion match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Spaghetti with White Bean Sauce
Ingredients
Directions
Make the bean sauce
Heat the olive oil in a non-stick frying pan.
Add the garlic, onion, bell pepper, and celery and cook over medium heat until soft but not brown, about 4 minutes.
Stir in the white beans and cook for 1 minute.
Add the stock or bean liquid, half the parsley, pepper flakes, and salt and pepper to taste.
Simmer until the beans are quite soft, about 20 minutes.
Coarsely mash the beans with a fork.
Cook and serve
Cook the spaghetti in a large pot of 4 quarts rapidly boiling salted water until al dente, about 8 minutes.
Drain the spaghetti well.
Meanwhile, bring the sauce to a boil.
Transfer the spaghetti sauce to a large shallow bowl and mix well.
Sprinkle the spaghetti with the remaining parsley and serve immediately with freshly grated cheese on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Soften and mash to form the body of the sauce, adding creaminess and thickness.
- Spaghetti
- Forms the base of the dish, carrying the bean sauce.
- Celery
- Softens into the sauce base, adding savory vegetable flavor and texture.
- Red onion
- Softens during cooking to build a sweet, savory base for the sauce.
- Romano cheese
- Adds salty, savory flavor when grated over the finished dish.
The step that matters
Simmering the beans until quite soft. Beans must cook long enough to become fully tender; undercooked beans stay firm and grainy and will not mash into a smooth sauce.
Swap the beans
How well each one fits the dish's main ingredients (olive, garlic, onion, pepper, celery, parsley, romano cheese):
- Beansthe original
- Chickpeafits about as well
- Lentilsfits about as well
- Black-eyed peafits less well
Fit is the average pairing score against olive, garlic, onion, pepper, celery, parsley, romano cheese. Candidates are from the same food group and used in at least 100 recipes.
