# Expert Insights:

01 -
  • It turns frozen convenience food into a gourmet comfort meal without any heavy lifting.
  • The sauce becomes incredibly velvety as it mingles with the potato starch from the pierogi.
02 -
  • Resist the urge to cook this on the high setting because the pierogi skins can become unpleasantly tough.
  • If you find the sauce too thick at the end a tiny splash of hot broth will loosen it right up.
03 -
  • Always use freshly grated cheese because pre shredded bags are coated in starch that prevents a perfectly smooth melt.
  • Switch to cream of chicken soup if you want a milder flavor that lets the kielbasa shine even brighter.
