  • Bring a large pot of salted water to a boil and cook penne pasta according to package directions, removing about 2 minutes before the time indicated on the box so the pasta is slightly underdone. Drain, then add to the skillet with the cream sauce along with sliced leftover steak. Return to the heat, stirring frequently for 1 minute to mix everything together. Serve, and enjoy!

  • Cook pasta in boiling water with a bit of salt added. Pull it off of the heat to drain 2 minutes before the time indicated on the box so it is just slightly underdone.
  • Do not let the pasta sit in the colander, or it might stick together and continue to cook.
  • Half and half can be used in place of heavy cream for a lighter pasta.
  • Add grated Parmesan cheese to the sauce to make it extra rich!
  • Mixed mushrooms can be used in place of cremini if you prefer.
