Essential Ingredients for Success

The Foundation:

• 3 packages Mrs. T’s Cheddar Pierogies (frozen)
• 4 cups chicken broth
• 1 lb kielbasa, sliced

The Creamy Base:

• 8 oz block cream cheese
• 1 cup shredded cheddar cheese
• Salt and pepper to taste

The Finishing Touch:

• Thinly sliced green onions (optional garnish)
• Additional shredded cheddar cheese for topping

Step-by-Step Preparation Guide

Crockpot Preparation: Begin by spraying a 4-quart crockpot with cooking spray to prevent sticking and ensure easy cleanup. This step is crucial for a casserole that will slide out effortlessly and maintain its beautiful presentation when served.

Building the Base Layer: Add 3 cups of chicken broth to the bottom of the prepared crockpot. This creates the liquid foundation that will transform into a creamy sauce during cooking. The broth provides essential moisture and depth of flavor that will be absorbed by the pierogies.

Adding the Stars: Layer the frozen cheddar pierogies directly into the crockpot – there’s no need to thaw them beforehand, which makes this step incredibly convenient. The frozen pierogies will cook perfectly in the moist environment of the slow cooker, absorbing flavors while maintaining their tender texture.

Incorporating the Kielbasa: Spread the sliced kielbasa evenly across the pierogies, ensuring every portion of the casserole will have that smoky, savory flavor. The kielbasa will release its juices during cooking, adding another layer of richness to the developing sauce.

First Cheese Layer: Sprinkle the shredded cheddar cheese over the kielbasa and pierogies, reserving some for the final topping. Season with salt and pepper to taste, keeping in mind that both the kielbasa and cheese will add saltiness to the dish.

Initial Cooking Phase: Gently stir the mixture to ensure the pierogies are coated in broth and evenly distributed throughout the casserole. Set the crockpot to cook on high for 3-4 hours or on low for 6 hours. The low and slow method allows for deeper flavor development and ensures the pierogies become perfectly tender.

Preparing the Cream Cheese Mixture: About 30 minutes before the cooking time is complete, prepare the cream cheese mixture that will create the signature creamy sauce. In a microwave-safe bowl, combine the cream cheese with the remaining cup of chicken broth. Microwave for 30 seconds to 1 minute, until the cream cheese is soft and easily mixable.

Creating the Smooth Sauce: Whisk the warm cream cheese mixture until completely smooth and lump-free. This creates a pourable sauce that will seamlessly integrate into the casserole, providing richness without creating clumps or uneven texture.

Final Assembly: Pour the smooth cream cheese mixture evenly over the contents of the crockpot, ensuring it reaches all areas of the casserole. Add the reserved shredded cheddar cheese on top for an extra layer of cheesy goodness. Cover and cook for an additional 30 minutes on low heat to allow the sauce to thicken and all flavors to meld together.

Serving Preparation: Once cooking is complete, gently stir the casserole to combine all elements, creating a cohesive dish where the creamy sauce coats every pierogi and piece of kielbasa. The stirring should be gentle to maintain the integrity of the pierogies while ensuring even distribution of the sauce.

Professional Tips for Perfect Results

Pierogi Selection: Mrs. T’s Cheddar Pierogies work exceptionally well in this recipe due to their sturdy construction and complementary flavor. Other flavors like potato and onion or four cheese also work beautifully. Avoid delicate pierogies that might fall apart during slow cooking.

Kielbasa Preparation: Slice the kielbasa into rounds about 1/4 to 1/2 inch thick for the best texture and flavor distribution. You can use any variety of kielbasa, from traditional Polish to turkey kielbasa for a lighter option. Pre-browning the kielbasa in a skillet before adding to the crockpot will add extra flavor depth.

Liquid Management: The chicken broth should be low-sodium to prevent the dish from becoming too salty. If your broth is regular sodium, reduce the added salt accordingly. The liquid will reduce and concentrate during cooking, so start conservatively with seasonings.

Cream Cheese Technique: Room temperature cream cheese blends more easily, but the microwave method works perfectly for this recipe. Make sure to whisk thoroughly to prevent lumps that won’t dissolve during the final cooking phase.

Timing Considerations: The low and slow method produces the best results, but if you’re short on time, the high heat method works well too. Just check periodically during the last hour to ensure the liquid hasn’t evaporated too much.

Serving Suggestions and Variations

This casserole is hearty enough to serve as a complete meal, but it pairs wonderfully with simple sides that complement its rich flavors. A crisp green salad with vinaigrette helps cut through the richness, while steamed vegetables like broccoli or green beans add color and nutrition to the plate.

Classic Accompaniments:

• Mixed green salad with tangy vinaigrette
• Steamed broccoli or green beans
• Crusty bread or dinner rolls
• Pickled vegetables for acidic contrast

Flavor Variations:

• Bacon and onion version using crispy bacon instead of kielbasa
• Mushroom and herb variation with sautéed mushrooms and fresh thyme
• Spicy version with jalapeños and pepper jack cheese

Protein Alternatives:

• Polish sausage or bratwurst for different flavor profiles
• Leftover ham or turkey for a lighter option
• Vegetarian version using plant-based sausage

Make-Ahead and Storage Options

This casserole is perfect for meal prep and can be assembled up to 24 hours in advance. Simply layer all ingredients except the cream cheese mixture in the crockpot, cover, and refrigerate. When ready to cook, add the cream cheese mixture during the final 30 minutes as directed.

Leftovers keep beautifully in the refrigerator for up to 4 days and can be frozen for up to 3 months. The casserole reheats well in the microwave or oven, though you may need to add a splash of broth or cream to restore the proper consistency.

For portion control, divide leftovers into individual containers for grab-and-go meals. The casserole maintains its creamy texture and rich flavor even after reheating, making it perfect for work lunches or quick dinners.

Frequently Asked Questions

Q: Can I use fresh pierogies instead of frozen? A: Yes, but reduce the cooking time slightly as fresh pierogies will cook faster. Add them during the last 2-3 hours of cooking to prevent them from becoming too soft.

Q: What if I don’t have Mrs. T’s pierogies? A: Any frozen potato-filled pierogi will work. Adjust cooking time based on the brand’s thickness and construction. Homemade pierogies also work beautifully.

Q: Can I make this without cream cheese? A: You can substitute with sour cream or Greek yogurt, but add them only in the last 15 minutes to prevent curdling. The texture will be slightly different but still delicious.

Q: How do I prevent the casserole from drying out? A: Make sure to use enough liquid initially and don’t lift the lid unnecessarily during cooking. If it seems dry, add more broth 1/4 cup at a time.

Q: Can I add vegetables to this casserole? A: Absolutely! Bell peppers, onions, or mushrooms work well. Add heartier vegetables at the beginning and more delicate ones during the last hour of cooking.

Q: What’s the best way to slice the kielbasa? A: Cut it into rounds about 1/4 to 1/2 inch thick. For extra flavor, you can halve the rounds or even quarter them for smaller pieces throughout the casserole.

Q: Can I use a different type of cheese? A: Yes! Monterey Jack, Swiss, or even cream cheese can be substituted. Use cheeses that melt well and complement the other flavors in the dish.

Q: How do I know when it’s done? A: The pierogies should be tender when pierced with a fork, and the sauce should be creamy and coat the ingredients. The cheese should be melted and the kielbasa heated through.

Q: Can I make this in a regular oven? A: Yes, bake covered at 350°F for about 45 minutes, then add the cream cheese mixture and bake uncovered for another 15 minutes until bubbly and golden.

Q: What if my casserole is too thick or too thin? A: If too thick, add more broth or cream. If too thin, mix a tablespoon of cornstarch with cold water and stir it in, then cook for 10 more minutes to thicken.
