 Step by Step Instructions

 STEP 1: 

I started by dropping some shredded rotisserie chicken into a mixing bowl.

I added two jars of alfredo sauce to the bowl.

 STEP 2: 

I added some chopped garlic and Italian seasoning to the bowl.

Then I stirred all of the ingredients together until well combined.

 STEP 3: 

I sprayed a 9 x 13 inch baking dish well with cooking spray.

I spread some frozen pierogies out in the bottom of the dish.

 STEP 4: 

I spooned approximately two thirds of the chicken mixture over the pierogies.

I sprinkled shredded mozzarella cheese on top.

 STEP 5: 

I placed more frozen pierogies on top of the cheese.

I spooned the remainder of the chicken mixture over the pierogies.

 STEP 6: 

I sprinkled more shredded mozzarella on top.

I also sprinkled some chopped cooked bacon pieces over the cheese.

 STEP 7: 

I covered the dish with aluminum foil and placed it in the oven.

I baked the casserole, covered for 30 minutes.

 STEP 8: 

After 30 minutes I removed the foil.

I left the casserole to continue baking, uncovered, for 25 minutes.

 STEP 9: 

Then I removed the dish from the oven and allowed it to rest for a few minutes.

I sprinkled fresh chopped parsley on top just before serving.

Then the creamy chicken alfredo pierogi casserole was ready to scoop and serve!

Every bite is loaded with cheesy pierogies, tender chicken, crispy bacon, and creamy Alfredo goodness.

The pierogies soak up the rich Alfredo sauce and bake up perfectly under a blanket of gooey mozzarella.
