How to Make Crockpot Pierogi Casserole with Kielbasa Recipe
Step 1: Prep Your Slow Cooker
Start by lightly greasing the insert of your 6-quart slow cooker. This simple step prevents sticking and helps the casserole come out in one beautiful piece. It’s the foundation for a fuss-free cooking experience.
Step 2: Layer the Pierogi
Place half of the frozen potato and cheese pierogi evenly across the bottom of the slow cooker. No need to thaw them—this keeps things quick and easy while locking in their soft texture during cooking.
Step 3: Add Kielbasa and Onion
Scatter half of the sliced kielbasa and half of the thinly sliced onions over the pierogi. These layers build the flavor from the bottom up, making sure every bite has a perfect balance of tender pierogi, savory sausage, and sweet onion.
Step 4: Whisk Together the Sauce
In a medium bowl, whisk together the condensed cream of mushroom soup, sour cream, garlic powder, black pepper, and smoked paprika until smooth. This creamy, savory mixture is what makes the casserole irresistibly comforting.
Step 5: Layer Sauce and Cheese
Pour half of the sauce over the pierogi, kielbasa, and onion layers. Then sprinkle half of the shredded cheddar cheese across the top. The cheese melts into the sauce, creating a luscious, cheesy blanket that brings everything together.
Step 6: Repeat the Layers
Now, layer the remaining pierogi, kielbasa, and onions. Spoon the rest of the sauce over this second layer, and finish with the remaining cheddar cheese. This double layering ensures every forkful is packed with goodness.
Step 7: Slow Cook Until Tender
Cover the slow cooker and cook on LOW for about 240 minutes (4 hours and 15 minutes), or until the casserole is bubbling and the pierogi are tender. The slow, gentle heat melds all the flavors beautifully and guarantees melt-in-your-mouth goodness.
Step 8: Garnish and Serve
Just before serving, sprinkle the chopped fresh chives or parsley on top for a bright pop of color and fresh flavor. This finishing touch elevates the dish and makes it look as good as it tastes.

FAQs
Can I use fresh pierogi instead of frozen for the Crockpot Pierogi Casserole with Kielbasa Recipe?
Yes! Fresh pierogi will work wonderfully and may cook even faster, so keep an eye on them during the slow cooking process to avoid overcooking.
