Recipe FAQs

Can I use fresh pierogi instead of frozen?

Yes, fresh pierogi work well in this casserole. Cooking time may be slightly shorter, so check after 3 hours to ensure they don't overcook.

What can I substitute for kielbasa?

You can use turkey kielbasa, smoked sausage, andouille, or even cooked bacon pieces. Vegetarian options include plant-based sausage or extra sautéed mushrooms.

Can I make this on high heat instead?

Yes, cook on HIGH for 2 to 2.5 hours instead of 4 hours on LOW. Watch carefully to prevent the edges from drying out.

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 minutes until heated through.

Can I add vegetables to this casserole?

Absolutely! Sautéed bell peppers, mushrooms, spinach, or broccoli florets work beautifully. Add them with the onion layers for extra nutrition and flavor.

Do I need to thaw the pierogi first?

No, use the pierogi straight from the freezer. They'll cook perfectly in the slow cooker and thawing them beforehand may make them too soft.
