Tips

  • Don’t skip browning the beef: Letting the beef brown adds depth and richness to the flavor, so don’t rush this step.
  • Cook the shells al dente: Boil them until just tender—overcooking makes them harder to stuff and too soft in the final dish.
  • Pre-mix the sauce: Stir the cornstarch into cold milk first to dissolve it, preventing any lumps in your sauce.
  • Layer cheese carefully: Tearing the provolone allows you to cover the shells fully, ensuring each one has a delicious cheesy top!
