Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the meat layer and fat that flavours the casserole as it cooks.
- Raw rice
- Absorbs liquid as it cooks, becoming tender and adding body to the dish.
- Potatoes
- Turn tender and starchy as they bake, adding bulk and body to the casserole.
- Tomato soup
- Supplies the liquid and acidity that cook the rice and vegetables and flavour the layers.
The step that matters
Pour the soup and water evenly over all the layers. Raw rice and vegetables need enough liquid to cook through; uneven pouring leaves dry spots where rice stays hard while other parts overcook.
Swap the onion
