Crockpot Pierogi and Kielbasa Casserole

So, what is a pierogi anyway? Pierogies are dumplings that can have savory or sweet fillings, boiled in water, and occasionally pan fried before serving.

They most likely originated in Asia, but became popular in Eastern Europe before making their way to the US and Canada. Pierogies are typically filled with mashed potatoes, cheese, mushrooms, or fruit.

The savory ones are often topped with a creamy sour cream sauce which is where this easy recipe comes in! Our recipe uses frozen pierogies to save on the prep work (although you could make some from scratch if you really wanted to, but we’re all about ease here).

You can choose whichever filling you’d like or switch it up each time you make this recipe. Slice up some kielbasa sausage, toss in the Crockpot with some broth, and let it simmer while you relax! Top some sharp cheddar cheese and green onions and you won’t believe how delicious this dish is!

How to Make Crockpot Kielbasa and Pierogi Casserole

In a large crock pot (6-7 quart), place the frozen pierogies, kielbasa slices, 3 cups of the chicken broth, and a dash of salt and pepper. Stir and cover.
Cook on High for 3-4 hours or on Low for 6-7 hours.
When you have about 30 minutes of cook time left, combine ½ cup of chicken broth, the cream cheese, and the sour cream in a saucepan over low heat. Whisk until melted and combined.
Pour this creamy mixture into the crockpot and sprinkle in 1 cup of shredded cheddar cheese. Stir once more, cover, and continue to cook for another 30 minutes.
The casserole will continue to thicken as it cools. Serve with a garnish of additional shredded cheese and some sliced green onions. Enjoy!

Tips and Variations

Make sure to use regular sized pierogies instead of mini ones. The mini pierogies have a tendency of falling apart while everything is cooking.
If you aren’t a kielbasa fan, you can always switch your protein to chicken, bacon, turkey, etc.
Fried onions as a garnish add a bit of crunch to the casserole.
Change up the flavor of pierogi and the type of cheese used to keep the flavors in this recipe new and exciting each time you make it!
The sauce for this crockpot pierogi and kielbasa casserole looks thin when it comes out of the slow cooker, but it will thicken nicely as it cools.
