Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ground beef
- Provides the meat base and savory browning flavor as it cooks in the dish.
- Rice
- Absorbs liquid as it cooks, becoming the tender starchy body of the casserole.
- Dry onion soup mix
- Seasons the rice and meat with concentrated onion flavor and salt.
- Condensed cream of mushroom soup
- Adds moisture and a creamy, thickened sauce that coats the rice and meat.
The step that matters
Cover and bake. Covering the dish traps steam so the rice cooks fully in the liquid. Uncovered, the surface can dry out while the rice stays firm underneath.
Swap the onion
How well each one fits the dish's main ingredients (beef, rice, cream, mushroom):
- Potatofits about as well
- Asparagusfits about as well
- Onionthe original
- Spinachfits about as well
Fit is the average pairing score against beef, rice, cream, mushroom. Candidates are from the same food group and used in at least 100 recipes.
