# Expert Tips:

01 -
  • The slow cooker does all the work while you go about your day, returning to a meal that tastes like you spent hours standing over the stove.
  • Those creamy, cheesy layers create little pockets of flavor that somehow taste even better as leftovers the next day.
02 -
  • Do not cook this on HIGH to save time, as the dairy products can separate and the pierogi will get mushy rather than tender.
  • Leaving the slow cooker lid off for the last 10 minutes helps some of the excess moisture evaporate, giving you a thicker, more spoonable casserole rather than a soupy consistency.
03 -
  • If you can find them, use the mini pierogi rather than full-sized ones, as they distribute more evenly throughout the casserole and cook more consistently.
  • For a crispy top that mimics an oven-baked casserole, transfer to a baking dish after slow cooking and broil for 2-3 minutes until the cheese on top gets those beautiful golden spots.
