Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 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
- Cream of mushroom soup
- Provides a creamy, binding base that holds the casserole together.
- Cooked rice
- Adds bulk and body, soaking up the sauce as the casserole sets.
- Cut green beans
- Supply the main vegetable texture and moisture in the dish.
- Cheddar cheese
- Melts over the top and browns in the oven for a savory crust.
- Luncheon meat
- Adds savory, salty flavor and a firmer, meaty bite.
The step that matters
Cook onion until soft but not brown. Gently softening onion in butter draws out its sweetness without bitterness. Browning it too far turns it sharp and can taint the creamy sauce.
Swap the green beans
How well each one fits the dish's main ingredients (onion, butter, cream, mushroom, rice, meat, mustard):
- Potatofits better
- Shallotfits better
- Chivefits better
- Green beansthe original
