Recipe Help

Can I use fresh pierogi instead of frozen?

Yes, fresh pierogi work perfectly. Reduce cooking time to 2-3 hours on low since fresh pierogi cook faster than frozen.

What can I substitute for cream of mushroom soup?

Try cream of chicken or cream of celery soup. You can also make a homemade white sauce with butter, flour, and milk for a from-scratch option.

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 pierogi are tender and the casserole is heated through before serving.

How do I store and reheat leftovers?

Store covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire dish in a 350°F oven for 20-25 minutes.

Can I make this vegetarian?

Absolutely. Omit the kielbasa and add sautéed mushrooms, bell peppers, or vegetarian sausage. Use vegetable-based cream soup to keep it fully vegetarian.

Do I need to thaw the pierogi first?

No, use pierogi straight from the freezer. The slow cooker will gently cook them through without any need for pre-thawing.
