Reusing Execution Plan

I've created a stored procedure and tried to compare the execution plans by passing different parameters to it. The execution plan in all the cases is displayed as same. But how can i make sure that SQL Server is using the same execution plan from memory each time i execute my stored procedure. I want to make sure its not recreating the execution plan each time i call the stored procedure
Appreciate if anyone can help me to trace that
Lots of thanks in advance.See my other reply. Please don't multipost.
