I always have boxes of frozen pierogies in the freezer. One reason is that Matty, 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 a full family meal out of them without breaking the bank. 

I’m sure homemade pierogies are better, but the frozen variety will do just fine for us. I’ve never made them before because they seem like a lot of extra work.

This baked casserole reminds me a little of a ravioli. The pierogies are the “pasta” with the spaghetti sauce. I use a jar of pasta sauce to save on 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 really 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 then 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. They are softer and more tender and suit this recipe more if they are boiled.

Recipe Tips

  • You can prep this casserole ahead of time if you need to (ie. 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 a little extra 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. 
  • Need an amazing comfort recipe to share? Bring this family favorite to potluck and parties.

How to Store

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 it doesn’t take up too much real estate in the fridge.

You also freeze Pierogi Casserole. Place in freezer safe containers and freeze for up to 3 months.
