Can I Use Fresh Pierogies Instead of Frozen?

Absolutely, you can use fresh pierogies if you prefer. Just keep in mind that fresh pierogies might cook a bit quicker than frozen ones, so you’ll want to check on your casserole a bit earlier to avoid them turning mushy.

Slow Cooker Pierogi Casserole Ingredients

• 4 cups of chicken broth, use divided
• 2 bags (16 ounces each) of frozen pierogies (cheddar or onion) – I recommend Mrs. T’s brand
• 2 cups of shredded cheddar cheese, use divided
• 1 pound of smoked Polska kielbasa, sliced
• Salt and pepper, to taste
• 8 ounces of cream cheese, softened to room temperature
• Sliced green onions, for garnish (optional)

How To Make Slow Cooker Pierogi Casserole

1. Prep Your Slow Cooker: Into your 4-6 quart crockpot, add three cups of chicken broth, frozen pierogies, half the cheddar cheese (1 cup), and the sliced kielbasa. Season with salt and pepper to your liking.
2. Cook It Up: Set your slow cooker to high and cook for 3-4 hours, or opt for a low setting for about 6 hours. Either way, you’re in for a treat.
3. Cream Cheese Magic: About 30 minutes before you’re ready to serve, take the remaining chicken broth (1 cup) and the cream cheese. Heat them together either in a microwave until warm or on a stovetop. Whisk until you’ve got a smooth and creamy mixture.
4. Final Touches: Pour the cream cheese mixture into the crockpot and give everything a good stir. Sprinkle the remaining cheddar cheese on top. Cover and set the cooker on low for another 30 minutes to let everything melt together beautifully.
5. Serve and Enjoy: Ladle up your casserole and if you feel like it, throw some sliced green onions on top for a bit of crunch and color.

Could I Make This Without Kielbasa?

Yes, you can definitely make the Pierogi Casserole in a Slow Cooker without kielbasa. If you’re looking for a vegetarian option, just skip the kielbasa or replace it with a vegetarian sausage to keep that hearty texture. The dish will still be delicious with the cheesy pierogies and creamy sauce!

Recipe Tips

• Optimize Cooking Time: If you want your Pierogi Casserole to have a bit more crunch to the pierogies, consider sautéing them lightly before tossing them in the slow cooker.
• Cheese Varieties Matter: Don’t shy away from experimenting with different types of cheese; a mix of sharp cheddar and mozzarella can add a rich, complex flavor profile to your casserole.
• Enhance with Herbs: Throwing in fresh herbs like dill or parsley about 15 minutes before the end of cooking can inject a fresh, vibrant layer of flavor into your dish.
• Layering is Key: For a more even distribution of textures and flavors, layer your pierogies and kielbasa instead of mixing them all at once, ensuring every bite is as good as the last.

Recipe Variations

• Spice It Up: If you fancy a bit of a kick, add a teaspoon or two of red pepper flakes or a splash of hot sauce to the cream cheese mixture to heat things up.
• Meaty Additions: For those who want even more protein, consider adding ground beef or crispy bacon bits to the casserole for additional flavor and texture.
• Low-Carb Solution: Replace traditional pierogies with cauliflower-based alternatives, which can offer a lower-carb version of this dish without sacrificing the creamy, comforting essence.
• Gluten-Free Option: Use gluten-free pierogies and ensure your kielbasa and other added ingredients are certified gluten-free, making this dish accessible for those with dietary restrictions.

What To Serve With Pierogi Casserole

Serve your Pierogi Casserole with roasted Brussels sprouts with balsamic glaze, Beetroot Risotto, a cucumber dill salad, and garlic sautéed mushrooms.

You can also pair this dish with pickled red onions for an extra zing, and a chilled apple slaw to add a refreshing crispness.

How To Store Leftover Pierogi Casserole

In The Fridge:

To store leftover Pierogi Casserole in the fridge, first let it cool to room temperature. Then transfer it into an airtight container or cover the original dish tightly with plastic wrap. It will stay fresh for up to 3 days when properly refrigerated.

In The Freezer:

Pierogi Casserole can be frozen, though the texture of pierogies may slightly soften upon reheating. To freeze, cool the casserole completely and transfer it into a freezer-safe container or a heavy-duty freezer bag. It will keep well for up to 2 months.

How To Reheat Leftover Pierogi Casserole

Reheat your leftover Pierogi Casserole by placing it in a 350°F oven for about 20 minutes, or until heated through. Cover the dish with foil to prevent the top from drying out.

For a quicker method, microwave individual servings for 2-3 minutes, stirring halfway to ensure even heating.
