Crock Pot Pierogi Kielbasa

This Crock Pot pierogi casserole with kielbasa is pure comfort food magic on a chilly night. Tender cheese or potato filled pierogies mingle with savory kielbasa and sweet caramelized onions under a blanket of gooey cheddar all made hands off in your slow cooker. I reach for this recipe when time is tight but everyone craves hearty satisfying flavors that make the house smell amazing.

The first time I made this my family hovered over the slow cooker all afternoon because it just smelled so good. Now it is a go to for cozy weekends snow days and potlucks.

Gather Your Ingredients

• Frozen pierogies: Choose cheese or potato filled for a fluffy chewy base that soaks up sauce look for brands with natural ingredients if possible
• Kielbasa sausage: Delivers smoky depth and hearty protein ask for one made with quality pork at the deli counter for best flavor
• Large onion: Sliced thin for natural sweetness and that irresistible caramelized edge
• Shredded cheddar cheese: Melts into gooey layers pick a sharp variety for a richer bite or mild for kid appeal
• Sour cream: Adds creaminess and a gentle tang choose full fat for extra luscious results
• Butter: Used to sauté and build flavor stick to real butter for best richness
• Garlic powder: Boosts savory flavor pick fresh or fragrant powder
• Salt and black pepper: To round everything out always taste before the final layer
• Fresh parsley: For a pop of color and brightness always use fresh chopped just before serving for best aroma

How to Make It

Prep and Sauté the Kielbasa and Onions:

In a large skillet melt the butter over medium heat. Add sliced kielbasa and cook for five to seven minutes until it takes on some golden brown color. Add the sliced onions and continue to sauté until they turn soft and caramelized about eight to ten minutes. Sprinkle in garlic powder salt and pepper at the end. Stir well and remove from heat.

Assemble in the Crock Pot:

Coat the inside of your slow cooker with a touch of nonstick spray so nothing sticks. Spread out the frozen pierogies in an even layer at the bottom. Spoon the sautéed kielbasa and onion mixture evenly over the top. Sprinkle the shredded cheddar evenly in a layer above that.

Add Creamy Layer and Cook:

Dollop the sour cream across the cheese and spread evenly with the back of a spoon. Place the lid on your slow cooker. Set to cook on low for three hours or high for one to one and a half hours until everything is warmed through the cheese is melted and bubbly.

Finish and Serve:

Remove the lid and check that the pierogies are tender. If you crave a crispy browned top transfer the casserole to an oven safe dish and broil under high heat for a couple of minutes until just golden and bubbling. Scatter fresh chopped parsley over the finished casserole right before serving.

The sweet flavor of deeply caramelized onions is something I look forward to every time I make this. My kids beg to help layer the ingredients they call it building the dinner mountain and take turns sprinkling cheese and parsley.

Flavor Boosters

Pack leftovers in airtight containers and refrigerate for up to four days. Reheat portions in the microwave or oven adding a splash of cream or broth if it looks dry. This dish also freezes well just let it cool then freeze slices for up to three months.

Serving Suggestions

Serve this casserole with a crisp green salad and crunchy pickles to balance the richness. For potlucks keep it warm right in the slow cooker or transfer to a serving dish for a family style meal. Warm rye bread on the side is always a hit at my table.

Creative Twists

If you cannot find kielbasa try smoked sausage or cooked bratwurst. You can use Monterey Jack instead of cheddar for a milder cheese experience or mozzarella for extra stretch. For the onions try using leeks for a more delicate flavor.

This dish brings together the best of comfort and convenience. Enjoy each bite and make it your own family classic.
