How to Make Crockpot Pierogi Casserole with Kielbasa
Step 1 — Prep and grease the slow cooker
First, lightly grease the slow cooker with butter or nonstick spray. I find this helps pierogies lift easily. It prevents sticking and keeps cleanup simple.
This prep sets up the Crockpot Pierogi Casserole with Kielbasa for easy layering. A well-greased cooker means clean edges and stable layers. Plus, it makes serving a breeze, honestly.
Step 2 — Make the creamy sauce
In a medium bowl, mix sour cream, cream cheese, and melted butter until smooth. Add minced garlic, paprika, and pepper. Stir until the mixture feels creamy and cohesive.
This creamy sauce is the soul of the Crockpot Pierogi Casserole with Kielbasa. Dare I say it’s the secret to that glossy, clingy finish? Stir and set aside while you layer.
Step 3 — Layer pierogies, kielbasa, onions, sauce, and cheese
Spread half the pierogies across the bottom. Then add half the kielbasa and onions. Pour on half the creamy sauce and sprinkle cheese.
Repeat with remaining ingredients, finishing with cheese on top. This top layer helps seal flavor and keeps everything cohesive. Even if the layers aren’t perfectly even, it will taste fantastic.
Step 4 — Cook and check for bubbly, heated through
Cover and cook on Low for 4 to 5 hours, or High for 2 to 3 hours. Check once at the halfway point if you’re unsure. The dish is ready when everything is heated through and bubbly around the edges.
If you’re short on time, resist lifting the lid too often. Trust the timer and your nose; cheese will smell like comfort. A quick stir at the end helps mingle melted cheese with pierogies.
Step 5 — Stir gently, finish with parsley, and serve
Stir gently to blend the melted cheese with the pierogies. Sprinkle chopped parsley for color and a fresh note. Serve hot for best texture and flavor.
If you have leftovers, store in an airtight container. Reheat gently to preserve creaminess. This dish rewarms nicely the next day.
