# Expert Suggestions:

01 -
  • The slow cooker does all the work while you go about your day, returning to a house filled with mouthwatering aromas that instantly make everyone hungry.
  • The contrast between the tender pierogi, smoky kielbasa, and creamy cheese sauce creates layers of flavor that somehow taste even better as leftovers the next day.
02 -
  • Resist the urge to cook this on HIGH to save time, as the pierogi may become gummy and the edges of the casserole will overcook before the center is done.
  • If your slow cooker runs hot, check the casserole at the 3-hour mark, as overcooking can dry out the edges while the center remains perfect.
03 -
  • Taking five minutes to brown the kielbasa slices in a hot skillet before adding them to the slow cooker adds a depth of flavor that transforms this good recipe into a great one.
  • A tablespoon of whole grain mustard whisked into the sauce mixture brings a subtle tangy complexity that complements the pierogi and kielbasa perfectly.
