Creamy Pierogi Casserole Recipe

If you grew up in certain areas of the country, you’re probably very familiar with pierogis. They’re little Eastern European dumplings filled with a potato mixture, cheese, cabbage, and other ingredients. And even if you’re not from a part of the U.S. with a large Polish population, you’ve probably seen boxes of pierogis at the grocery store!

You can boil, bake, or fry frozen pierogis. However, my absolute favorite way to serve them is in a creamy, cheesy casserole. If you’re looking for a new way to use pierogis or a casserole that’s not the same old variation of potatoes, ground beef, and cheese, you’re going to love this pierogi casserole.

Pierogi casserole is the ultimate comfort food dish! It combines your choice of frozen pierogis with a creamy mushroom sauce, cheddar cheese, crispy bacon, and a sprinkle of chives. You can easily put your own spin on it, too.

For example, you can add sautéed mushrooms and caramelized onions to up the veggie factor. Or, maybe add some sliced and cooked kielbasa for extra protein.

With a cooking time of just 30 minutes, this casserole is one of my favorite recipes for an easy dinner. You can also double the recipe, and bring pierogi casserole to your next potluck. It’s going to rank right up there with Cheeseburger Tater Tot CasseroleEasy Cheesy Potatoes, and Taco Casserole in your list of most favorite casserole recipes!

Ingredients for Pierogi Casserole

To print: see recipe card below

Ingredients to make pierogi casserole.
  • 2 tablespoons olive oil You can substitute canola oil or vegetable oil.
  • 1/2 onion – Yellow or white both work here.
  • 2 minced garlic cloves
  • 1 (10.5 ounce) can cream of mushroom soup – Cream of vegetable soup or cream of chicken soup are also delicious.
  • 1/2 cup sour cream – Use full-fat sour cream for the richest sauce.
  • 1/4 cup milk – You can use whole milk, reduced fat, or even dairy-free milk.
  • 1 cup shredded cheddar cheese Feel free to use your preferred shredded cheese. Freshly shredded cheese from a block is best! Pre-shredded cheese has a waxy coating to extend shelf-life and this reduces the flavor and makes the cheese harder to melt.
  • 1/2 cup bacon – Cook the bacon, and crumble it.
  • 1 (16-ounce) package frozen pierogis You can use any variety your family likes. Thaw them in the refrigerator all day so they’re ready to go by the time you start dinner.
  • 3 tablespoons fresh chives Or, substitute sliced green onions for a stronger flavor. Fresh parsley also works well.
  • Nonstick cooking spray


  • Substitute cream of chicken soup for the cream of mushroom soup.
  • Save some prep time and use bacon bits instead of cooking the bacon.
  • Add sautéed mushrooms to the sauce mixture.

Directions for How to Make Pierogi Casserole

  1. Prepare: Preheat your oven to 375 degrees Fahrenheit. Coat a 9 x 9 casserole dish with nonstick cooking spray.
  2. Cook the aromatics: Heat a large skillet set over medium heat. Cook the onion and garlic in olive oil until the onion is translucent.
  3. Finish the sauce: Remove the skillet from the heat. Then, stir in the cream of mushroom soup, sour cream, milk, cheddar cheese, and bacon.
  4. Assemble: Spread half of the sauce on the bottom of the prepared baking dish. Arrange the pierogis over the top. Next, spread the remaining sauce mixture over the top, and add the chives.
  5. Bake: Place the dish in the oven, and bake until the top is golden brown and the sauce is bubbling around the edges. Cool for four to five minutes before serving.

Serving Suggestions

Traditionally, pierogis are served with condiments like sour cream and butter or fried onions. You can add any variety of toppings to this recipe!

I love to serve it as a main dish with sides like roasted vegetables, mashed potatoes, or a simple salad. You can also cook up some sausage, bacon, and ground beef to serve alongside the casserole to make a heartier meal!

How to Store Leftover Pierogi Casserole

  • You can make pierogi casserole ahead of time. Simply assemble the ingredients in a baking dish, and keep it covered with foil in the refrigerator. Remove the foil, and let the casserole sit at room temperature while the oven preheats.
  • Store leftovers in an airtight container in the refrigerator for up to three days. Or, cover the baking dish with plastic wrap or aluminum foil.
  • To reheat, place the casserole in the oven at 350 degrees Fahrenheit for about 15 minutes or until warmed through. You can also reheat it in the microwave. If the casserole browns too quickly, cover it with foil and bake until warm.

Quick Tip

Depending on the size of the pierogis and your baking dish, you may have to overlap them slightly to get them to fit. This is fine!
