This is a great recipe for a make-ahead meal and can also be frozen and ready for a quick easy dinner the whole family will love.

What is a Pierogi?

Pierogies are dumplings filled with mashed potatoes and sweet or savory ingredients. Its origins are rooted in European cuisine.

Fun fact: Pierogi is the national dish of Poland and dates back to the 13th century.

They are usually cooked in boiling water and then often pan-fried before serving.

Traditional Polish pierogis might be served with a dollop of sour cream, cottage cheese, Greek yogurt, or melted butter with fried onions.

Ingredients Needed

  • Cheese Pierogis – I use frozen pierogi found in the frozen aisle of your supermarket. You can also use fresh or homemade pierogi.
  • Onion – White or yellow onion both work well in this recipe. One of my favorite shortcuts is buying chopped onions in the produce or frozen section of my grocery store. Saves me time and tears!
  • Ricotta cheese – Cottage cheese can also be used. I recommend using 4% fat and blending it for a bit in your food processor so your cottage cheese mixture will have the same creaminess as ricotta.
  • Cheddar cheese – You need shredded cheese for this casserole. You can buy pre-shredded cheese or grate your own.
  • Kielbasa – I prefer this sausage, but you can experiment with different meats such as Italian sausage and ground pork sausage. It would also be a perfect way to use up leftover ham or shredded chicken.
  • Green onions – You will garnish your casserole with these chopped onions. You could also use chives, or parsley if you don’t want additional onion flavor.
  • Pantry staples – Unsalted butter, large eggs, salt, and black pepper.

How to Make Pierogi Casserole

  1. Preheat the oven to 350°F and spray a 9×9 baking dish with nonstick cooking spray.
  2. In a large skillet over medium heat, melt butter and brown the frozen pierogies and diced onions in two batches. Set aside to cool slightly.
  3. In a mixing bowl, combine the ricotta cheese, beaten eggs, salt, and pepper.
  1. To assemble the casserole, start by layering half of the pierogis on the bottom of the prepared dish. Add 1/3 of the ricotta mixture, 1/3 of the kielbasa, and 1/3 of the cheddar cheese. Repeat with the remaining pierogis and other ingredients, finishing with a layer of cheese on top.
  2. Cover the casserole with foil and bake for 40 minutes. Remove the foil and bake for an additional 10 minutes until the cheese is golden brown and bubbly.
  3. Let the casserole cool slightly before topping with sliced green onions and serving. Enjoy!

This pierogi casserole makes a great freezer meal. You can store it for up to 3 months. Let the casserole cool to room temperature.

To reheat, thaw overnight in the refrigerator. Bake at 350F for 25-30 minutes or until the internal temperature reaches 165F.

Do you have to cook the frozen pierogi before making the casserole?

You don’t have to fully cook the frozen pierogi before making the pierogi casserole.

However, it is recommended to brown them in a pan over medium heat for a few minutes on each side before layering.

This step adds extra flavor and texture to the pierogi and helps to prevent them from becoming mushy in the casserole.
