Ingredients

This recipe relies on simple ingredients that come together beautifully in the slow cooker.

3 boxes mini cheddar pierogies – Mini pierogies cook evenly and are perfect for bite-sized portions. Cheddar flavor enhances the overall cheesiness.
4 cups chicken broth – Helps cook the pierogies while creating a flavorful base for the sauce.
8 oz cream cheese (block) – Melts into the broth to create a thick, creamy texture.
1 cup shredded cheddar cheese – Adds extra richness and that irresistible melted cheese pull.
1 pound kielbasa, sliced – Smoked kielbasa brings bold, savory flavor that balances the creaminess perfectly.
Salt and pepper, to taste – Enhances all the flavors.

Step-by-Step Instructions

Step 1: Layer the Ingredients

Place the mini pierogies into the crockpot. Add the sliced kielbasa evenly over the top.

Step 2: Add the Liquid and Cheese

Pour in the chicken broth. Cut the cream cheese into cubes and scatter over the mixture. Sprinkle the shredded cheddar cheese on top. Season with salt and pepper.

Step 3: Slow Cook

Cover and cook:

High: 3–4 hours
Low: 6 hours

The pierogies will become tender and absorb the rich flavors while the cheeses melt into a creamy sauce.

Step 4: Stir and Serve

About 30 minutes before serving, gently stir everything together to fully blend the melted cream cheese into the broth, forming a smooth, luscious sauce.

Serve hot and enjoy!
