What Are Pierogies?

Pierogies are traditional dumplings that originated in Poland and are very popular across Eastern Europe. They are usually filled with ingredients like:

• potatoes
• cheese
• onions
• meat
• sauerkraut

For this recipe, cheddar pierogies work best because they become extra creamy and flavorful while cooking in the crockpot.

Using frozen pierogies also makes this recipe incredibly convenient since there’s no need to thaw them beforehand.

• 3 packages frozen Mrs. T’s Cheddar Pierogies
• 4 cups chicken broth, divided
• 1 (8-ounce) block cream cheese
• 2 cups shredded cheddar cheese, divided
• 1 pound kielbasa sausage, sliced into rounds
• Salt and black pepper to taste

Optional Add-Ins and Toppings

Want to customize the casserole? Here are some delicious additions:

• Sliced green onions or fresh chives
• Caramelized onions for sweetness

Equipment Needed

You only need a few simple kitchen tools:

• Crockpot or slow cooker
• Small saucepan
• Knife and cutting board
• Cheese grater
• Mixing spoon

This is one of those easy “dump-and-go” meals that requires very little preparation.

Step-by-Step Instructions

Step 1: Prepare the Creamy Cheese Sauce

In a medium saucepan over medium-low heat, combine:

• cream cheese
• 2 cups chicken broth

Stir continuously until the cream cheese melts completely and the mixture becomes smooth and creamy.

Next, add:

• 1 cup shredded cheddar cheese

Continue stirring until the cheese fully melts into the sauce. Season lightly with salt and pepper.

This creamy mixture creates the rich, cheesy base that makes the casserole irresistible.

Step 2: Prepare the Crockpot

Lightly grease the inside of your crockpot using butter or nonstick cooking spray. This helps prevent sticking and makes cleanup easier later.

Now begin layering the ingredients.

Start with:

• a layer of frozen pierogies
• a layer of sliced kielbasa
• a spoonful of cheese sauce

Repeat the layers until all ingredients are used.

Try to distribute the kielbasa evenly so every serving gets plenty of smoky sausage flavor.

Step 3: Add Remaining Broth

Pour the remaining 2 cups of chicken broth evenly over the casserole.

The broth helps keep the pierogies tender while cooking and prevents the casserole from drying out.

Do not stir too much once everything is layered.

Step 4: Slow Cook

Cover the crockpot with the lid and cook:

• On HIGH for 3–4 hours
  or
• On LOW for 5–6 hours

The casserole is ready when:

• the pierogies are soft and heated through
• the kielbasa is fully warmed
• the sauce is creamy and bubbling

Your kitchen will smell amazing by this point.

Step 5: Add Final Cheese Layer

About 30 minutes before serving:

• sprinkle the remaining 1 cup of shredded cheddar cheese over the top

Cover again and allow the cheese to melt completely.

This final layer creates a rich, gooey topping that takes the casserole to another level.

Tips for the Best Crockpot Pierogi Casserole

1. Do Not Thaw the Pierogies

Always use them frozen. Thawed pierogies can become too soft and fall apart during slow cooking.

2. Use Smoked Kielbasa

Smoked kielbasa adds a deep savory flavor that balances perfectly with the creamy cheese sauce.

You can also try:

• turkey kielbasa
• beef sausage
• spicy sausage

3. Avoid Overcooking

Slow cookers vary in temperature. Cooking too long may cause the pierogies to become mushy.

Check around the minimum cooking time first.

4. Add Vegetables

You can easily turn this into a complete meal by adding:

• broccoli
• spinach
• peas
• mushrooms
• bell peppers

5. Make It Extra Crispy

For a crispy cheesy topping:

• transfer the finished casserole to an oven-safe dish
• broil for 3–5 minutes

This creates a golden-brown cheesy crust on top.

Serving Suggestions

This casserole is already filling on its own, but it pairs wonderfully with:

• green salad
• roasted vegetables
• garlic bread
• steamed corn
• coleslaw

For extra richness, top each serving with:

• sour cream
• chopped chives
• bacon bits

Storage Instructions

Refrigerator

Store leftovers in an airtight container for up to 3–4 days.

Freezer

Freeze for up to 2 months.

For best results:

• cool completely before freezing
• store in freezer-safe containers

Reheating Instructions

Microwave

Heat individual portions for 1–2 minutes, stirring halfway through.

Stovetop

Oven

Bake covered at 350°F (175°C) until heated through.
