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.
Fry until lightly browned. Remove to a bowl and allow to cool while preparing other ingredients.
In a medium mixing bowl, stir together ricotta cheese, eggs fine sea salt and ground white pepper.

Notes
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.
