Recipe FAQs

Can I use fresh pierogi instead of frozen?

Yes, fresh pierogi work well and may cook slightly faster—check for doneness around 3 hours.

What other meats can I substitute for kielbasa?

Smoked sausage, andouille, or even cooked bacon work beautifully as alternatives.

Can I make this on high heat?

Cook on high for 2-2.5 hours, though low and slow gives better texture.

How do I store leftovers?

Refrigerate in an airtight container up to 4 days or freeze up to 3 months.

Can I assemble this ahead of time?

Assemble everything in the removable crock the night before, refrigerate, then start cooking when ready.
