Pierogi Casserole takes your favorite pierogi and layers them with creamy ricotta, smoky kielbasa and cheddar cheese. A family favorite and great for potlucks and parties!
Preheat oven to 350 degrees. Coat a 2 quart casserole dish with cooking spray.
In a large, heavy bottom skillet, melt butter over medium-high heat. Add half of the perogies and chopped yellow onion. When the first half is browned, remove and add second half.

If you are using frozen, don't worry if they aren't 100% thawed. If you use fresh, follow the same process, it will just take less time. Either way, they will heat all the way through during the baking process.
