Step‑by‑Step Instructions for Crockpot Pierogi Casserole

Step 1: Combine Ingredients in Crockpot
In a 4-6 quart crockpot, start by pouring in three cups of chicken broth. Then, add the frozen Mrs. T’s cheddar pierogies and the sliced kielbasa, mixing gently to combine. Finish by sprinkling in one cup of shredded cheddar cheese for a rich, cheesy base.

Step 2: Cook Casserole
Cover the crockpot and set it to cook on high for 3-4 hours or low for 6 hours. As it cooks, the pierogies will become tender and soak up that lovely chicken broth, while the kielbasa infuses a smoky flavor throughout the dish.

Step 3: Prepare Cream Cheese Mixture
About 30 minutes before cooking is complete, take out the cream cheese and warm it in a saucepan with the remaining chicken broth over low heat. Stir until the mixture is smooth and creamy, allowing the cream cheese to meld beautifully with the broth for added richness.

Step 4: Final Assembly
Once the cooking time is up, gently stir the cream cheese mixture into the crockpot, combining it well with the other ingredients for a luscious sauce. Then, top the casserole with the remaining shredded cheese and cover, cooking on low for an additional 30 minutes until melted and bubbly.

Step 5: Serve
To serve this delicious Crockpot Pierogi Casserole, spoon it onto plates while hot, optionally garnishing with fresh green onions for an added burst of flavor and a lovely pop of color. Enjoy the comfort and warmth of this hearty dish with your family and friends!

What can I do if the pierogies become mushy?
It’s important to keep an eye on the cooking time, as overcooking can lead to mushy pierogies.

Yes! If you have pets, it’s best to avoid sharing this dish with them, as some ingredients like cream cheese and certain spices can be harmful. Also, for allergy concerns, make sure to check the labels on your pierogies and kielbasa to ensure they don’t contain any allergens like gluten or dairy.
