Step 1

Begin by melting the unsalted butter in a medium-sized saucepan over a low flame.

Step 2

Once the butter is fully melted, gradually incorporate the all-purpose flour, whisking constantly to ensure the formation of a smooth roux.

Step 3

Slowly introduce the warm whole milk to the roux, continuing to whisk diligently to prevent any lumps from forming. Subsequently, increase the heat to medium-high, ensuring constant stirring until the mixture attains a thickened consistency.

Step 4

Upon achieving the desired thickness, fold in the finely chopped dried beef and incorporate the cayenne pepper. Continue to heat the mixture until the beef is adequately warmed.

Step 5

To serve, ladle the creamed beef mixture over slices of toasted bread.
