What Is Slow Cooker Pierogi Casserole?
Slow Cooker Pierogi Casserole is an easy crockpot dinner made with frozen potato and cheese pierogies, smoked sausage, onions, and a creamy cheddar cheese sauce.
Instead of boiling the pierogies separately, everything cooks together in the slow cooker. As the pierogies slowly cook, they absorb the flavorful broth and cream while staying soft and tender. The result is a hearty casserole that’s loaded with cheesy, comforting flavor.
Can You Cook Frozen Pierogies in the Slow Cooker?
Absolutely! Frozen pierogies are one of the best shortcuts for slow cooker meals.
No thawing is necessary.
The pierogies cook gently while absorbing the flavorful broth.
Cooking on low helps them stay tender without falling apart.
Since they’re fully assembled, there’s very little prep work.

Tips for the Best Slow Cooker Pierogi Casserole
- Brown the sausage before adding it to the slow cooker for extra flavor.
- Add the cream cheese mixture during the last hour so the sauce stays smooth and creamy.
- Stir gently to keep the pierogies from breaking apart.
- Use freshly shredded cheese for the creamiest sauce.
- Avoid overcooking, which can make the pierogies too soft.
- Let the casserole sit for about 10 minutes before serving so the sauce thickens slightly.
