Pierogi Casserole
Pierogi Casserole is a super easy dinner recipe perfect for busy weeknights. Made with frozen pierogis, mushrooms, onions, pasta sauce, and topped with Parmesan cheese. It’s a family favorite comfort food!
I always have boxes of frozen pierogies in the freezer. One reason is that my spouse LOVES them for a quick and filling dinner. Sometimes, he will even make them for a late-night snack.
They are also super cheap. You can get an entire family meal from them without breaking the bank.
I’m sure homemade pierogies are better, but the frozen variety will do just fine. I’ve never made them because they seem like much extra work.
This baked casserole reminds me a little of ravioli. The pierogies are the “pasta” with the spaghetti sauce. I use a jar of pasta sauce to save time. I have a Homemade Spaghetti Sauce, though, that you could try if you want more of a homemade taste.
It’s filling, hearty, and perfect for busy nights when you don’t feel like cooking dinner!

The Best Way to Cook Frozen Pierogies
I like to boil my frozen pierogies to cook them. That way, I know for sure they aren’t still frozen. You can also sauté them on the stove in a skillet or even bake them.
Some people boil their pierogies and finish them off in the skillet to give them a crispier crust.
For this recipe, I boil them since they will be covered in sauce. Boiling makes them softer and more tender, which suits this recipe better.
Recipe Tips and Tricks
- You can prep this casserole ahead of time if you need to (e.g., in the morning for tonight’s dinner). Cook the pierogies and assemble all the ingredients in the casserole dish. Cover and refrigerate until you are ready to bake. You might want to add some baking time since it’s going into the oven cold.
- Feel free to switch up the sauce. Alfredo sauce is also yummy!
- Want it really cheesy? Add 1 cup of shredded cheddar or mozzarella cheese on top before placing it in the oven.
- Add more veggies! This is a great clean-out your fridge kind of recipe to use up veggies in your fridge.

Storage Instructions
You can store any uneaten leftovers in the fridge for up to 3 days. I like to put leftovers in plastic storage containers so I can wash the casserole dish, and they don’t take up too much real estate in the fridge.
You can also freeze Pierogi Casserole. Place in freezer-safe containers and freeze for up to 3 months.

Would like approving casserole. I am tired of perogies alone
I made these tonite and they were delicious. I normally wait until the next day to hear from my picky eater but was so pleased with these I am not waiting. The only significant change I made was that I only used a 1 pound package of pierogis. I used the 4 cheese medley. When I opened the box and looked at I realized that one box would cover the bottom of the 9 X 13 pan. And I was right. I had some leftover onions from a recipe the night before. I added a cup of sliced mushrooms and a 24 oz jar of pasta sauce. Cooked it in a 350 oven for a half hour. It was so good. I had not had pierogis for quite some time and had forgotten how good they are. I served these with a recipe for oven baked pork chops and it made for wonderful dinner. Thanks for posting such an EZ and yummy recipe.
This looks delicious and easy too. I am pretty sure my son would eat it all.
Such a unique dish! Definitely going to give this recipe a try! Looks so yum!
