- ½ cup sour cream

Instructions

- Step 7: About 30 minutes before serving, sprinkle the shredded cheddar cheese evenly over the top of the casserole. Cover again and cook until the cheese has fully melted.
- Step 8: Once the cheese is melted and bubbly, serve the casserole warm for a delicious and satisfying meal.
Tips & Variations

FAQs
Can I use fresh pierogies instead of frozen?
Yes, fresh pierogies can be used. Reduce the cooking time slightly to prevent overcooking, as fresh pierogies soften faster than frozen ones.
Is it possible to prepare this casserole without a crockpot?
Absolutely. You can layer the ingredients in a baking dish, cover with foil, and bake at 350°F for about 45 minutes to 1 hour, until warmed through and bubbly. Add cheese during the last 10 minutes of baking.
