How to make Cheesy Pierogi Casserole

Start by spraying a large baking dish with nonstick cooking spray. Then layer half of the frozen pierogies in the casserole. Next, spoon half of the alfredo sauce on top. Next, sprinkle with crispy chopped bacon, chopped green onions, and some shredded mozzarella and cheddar cheese. Now layer the rest of the pierogies on top and spoon the rest of the alfredo sauce on top. Sprinkle with the rest of the chopped bacon, green onions, and remaining cheese.

Then cover with aluminum foil and bake for about 15 minutes. Remove the foil and continue baking for another 20-25 minutes or until the cheese is melted and the casserole is bubbly and cooked through.

This easy to make cheesy casserole is comfort food at its best.

Recipe notes and tips

Frozen pierogies are available in the freezer section of most grocery stores.
For ease in cleaning, grease the casserole dish.
You don’t have to pre-boil the pierogies. They will cook just fine layered with the sauce and the cheese.
You can use any combination of creamy melting cheese that you like. I think the mozzarella and cheddar combo tastes best with the alfredo sauce.
Replace the bacon with browned Italian sausage, smoked kielbasa, or ham.
Store leftovers in an airtight container in the refrigerator for up to 4 days.
The recipe reheats well in the microwave at reduced power.
To freeze this casserole, first cool completely, then cover with two layers of plastic wrap, followed by a layer of aluminum foil. Freeze for yo to 2 months. Thaw in the fridge overnight and reheat in the oven at 300 degrees for about 20-25 minutes or in the microwave at reduced power.
