# Expert Hints:

01 -
  • The slow cooker transforms frozen pierogi into incredibly tender dumplings that soak up all that creamy sauce
  • Its the kind of meal that makes the whole house smell amazing hours before dinner
  • Leftovers reheat beautifully and somehow taste even better the next day
02 -
  • Don't be tempted to cook on high heat for less time, the pierogi need those 4 hours on low to get perfectly tender
  • The sauce might look thin at first but it will thicken beautifully as it cooks
  • Lift the lid only to check doneness at the end, every peek adds cooking time
03 -
  • Spray your slow cooker insert generously, this cheesy dish loves to stick
  • Let it rest for 10 minutes before serving so the sauce sets slightly
  • Use a slotted spoon for serving so you can control how much sauce each person gets
