Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Form the edible shell that holds the filling and becomes tender when baked.
- Raw beef
- Provides the savory meat filling that sets as it cooks.
- Egg
- Binds the filling so it holds together when baked.
- Bread crumbs
- Absorb the cream and add body to the filling.
- Cream
- Adds moisture and richness to the filling.
- Butter
- Adds fat and helps the tops brown during baking.
The step that matters
Continue baking until the onions are brown. Covering the dish first traps steam so the onions soften and the filling cooks through. Uncovering afterward lets dry heat brown the tops; leaving the dish covered throughout would leave them pale and soft.
