Recipe FAQs

Can I use fresh pierogi instead of frozen?

Yes, fresh pierogi work well too. Just reduce the cooking time to about 2-3 hours on low, as fresh pierogi cook faster than frozen ones.

What can I substitute for cream of mushroom soup?

Cream of chicken, cream of celery, or even a homemade béchamel sauce make excellent alternatives. For a dairy-free version, try coconut milk mixed with cornstarch.

Can I make this on high heat?

Absolutely. Cook on high for 2-2.5 hours instead of 4 hours on low. Check after 2 hours to prevent overcooking the pierogi.

How should I store leftovers?

Store in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or oven with a splash of milk to refresh the creamy sauce.

Can I freeze this casserole?

Yes, assemble and freeze before cooking. Thaw overnight in the refrigerator, then cook as directed. Already-cooked portions can be frozen for up to 2 months.
