How to Make Pour the cream cheese mixture into the slow cooker and stir to combine

Step 1: Combine Everything Except the Cream Cheese

Start by grabbing your trusted 4–6 quart slow cooker. Add in three cups of chicken broth, all the frozen pierogies, half of the cheddar cheese, and those tempting slices of kielbasa. Give it all a gentle stir, letting the ingredients mingle and get cozy. Set your slow cooker to low for 6 hours (or high for 3–4 hours). No peeking needed—just let the slow heat work its wonders!

Step 2: Prep the Cream Cheese Mixture

About 30 minutes before it’s time to serve, you’ll make the magical component: the cream cheese mixture. In a microwave-safe bowl (or on the stovetop), gently warm the softened cream cheese with the remaining cup of chicken broth. Stir and whisk until the mixture is smooth, creamy, and pourable. This creamy blend is key to a sauce that’s smooth and lush, never lumpy or separated!

Step 3: Pour the cream cheese mixture into the slow cooker and stir to combine

This step is when everything comes together and the aroma fills your kitchen. Carefully pour the cream cheese mixture into the slow cooker and stir to combine with the warm pierogies and kielbasa. Watch as the sauce wraps lovingly around each morsel! Top with the last of the cheddar cheese, then cover and cook on low for an extra 30 minutes so the final cheese melts into perfection.

Step 4: Serve Hot and Garnish

Once your casserole is bubbling and golden, lift off the lid and soak in the coziness. Ladle portions onto plates or shallow bowls, then finish with a sprinkle of sliced green onions for color and freshness. Every bite is creamy, cheesy bliss!

Reheating
