How to Cook the Delicious Crockpot Pierogi Casserole with Kielbasa?

Step 1: Layer the Pierogi

Grab your crockpot and throw in the frozen pierogi—uh huh, from the bag! You don’t even need to thaw them; they’ll soften beautifully while cooking. Simply lay them out in a single layer on the bottom of the pot. Easy, right?

Step 2: Add Kielbasa & Onions

Now get your sliced kielbasa and spread it on top of the pierogi. Next, add in the chopped onions. Don’t worry about making it look beautiful — just make sure everything is spread out so that every bit has some smoky sausage flavor and a little oniony goodness.

Step 3: Season It Up

Time to bring in some flavor! Sprinkle everything liberally with garlic powder, a few shakes of salt and pepper. Want a bit more of a garlicky kick? Why the hell not — there isn’t such a thing


Tips For Making It More Delicious:

  • Peel and Freeze the Pierogi – No Thaw needed, just throw them in frozen! These can because of freezing start to get too tender and mushy upon thawing.
  • Layer Evenly for Best Flavor — Distribute ingredients so every bite has a perfect balance of flavor.
  • Use Full-Fat Ingredients for Extra Creaminess — Full-fat sour cream, cheese and soup make the sauce richer and more delicious.
  • Don’t Skimp on the Cheese — You want lots of cheese on top for that golden, melty goodness.
  • Let It Cook Low & Slow –4-6 hours on low yields perfect texture and flavor.
