Ingredients
Directions
Prepare
Season the chopped beef with salt and pepper.
Stir in the flour until well mixed.
Make the beef mixture
Place the beef in a small saucepan and add enough milk to nearly cover it.
Simmer gently for 10 minutes, then add the butter.
Serve
Toast the bread slices and arrange them on a platter.
Spread the beef mixture over the toast and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the savory meat base that the sauce is built around.
- All-purpose flour
- Thickens the milk as it simmers, giving the beef a creamy, spreadable texture.
- Milk
- Forms the liquid that cooks the beef gently and becomes the creamy sauce.
- Butter
- Adds richness and a smooth, glossy finish to the sauce.
- Bread
- Gives a crisp base that holds the beef mixture.
The step that matters
Simmer gently for 10 minutes. Gentle heat lets the flour hydrate evenly in the milk so the sauce thickens smoothly; a hard boil can scorch the milk or make it lumpy.
