Why it works: Rice and broccoli match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 609 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked rice
- Forms the body of the casserole and absorbs moisture from the soup and sour cream.
- Cream of mushroom soup
- Provides moisture and a creamy binding base that holds the casserole together.
- Cheddar cheese
- Melts into the filling and browns on top, adding richness and savory flavor.
- Sour cream
- Adds fat and tang, keeping the filling moist and creamy after baking.
- Broccoli
- Adds vegetable texture and flavor; thawed frozen broccoli releases water, so it adds moisture.
The step that matters
Adding the top cheese late. Cheese added at the start can over-brown or become greasy during the long bake. Adding it near the end and baking briefly lets it melt evenly while the filling stays creamy.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (celery, rice, broccoli, cream, mushroom, cheddar cheese, pepper):
- Potatobetter flavor fit
- Capsicumbetter flavor fit
- Tomatobetter flavor fit
- Onionthe original
Fit is the average pairing score against celery, rice, broccoli, cream, mushroom, cheddar cheese, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
