Questions & Answers

Can I use fresh pierogi instead of frozen?

Yes, fresh pierogi work well in this casserole. Reduce the cooking time to 2-3 hours on low, checking for doneness to avoid overcooking.

How do I prevent the pierogi from sticking?

Generously grease your slow cooker insert with butter or cooking spray before layering. The creamy sauce also helps prevent sticking during cooking.

Can I make this ahead of time?

Yes, you can layer all ingredients in the slow cooker insert the night before, cover, and refrigerate. Add 30-45 minutes to the cooking time when starting from cold.

What can I substitute for kielbasa?

Turkey kielbasa, smoked sausage, or andouille work well. For a lighter option, use chicken sausage. Just ensure your substitute has good smoky flavor.

How do I store leftovers?

Store in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or the entire dish in a 350°F oven until warmed through.

Can I cook this on high instead of low?

Yes, cook on high for 2-2.5 hours instead of 4 hours on low. Check that the pierogi are tender and the casserole is heated through before serving.
