Essential Kitchen Tools for Easy Cooking

For this recipe, the right tools make all the difference. Luckily, you don’t need anything fancy. Here’s a list of must-have kitchen essentials to make cooking this dish as seamless as possible:

Crockpot/Slow Cooker – The star of this recipe. I used a 6-quart crockpot, which had plenty of space for all the layers without overcrowding.
Sharp Knife and Cutting Board – To slice the kielbasa evenly and chop any additional toppings or ingredients.
Mixing Bowls – One or two bowls are perfect for prepping your cream sauce or mixing cheese.
Measuring Cups and Spoons – For precise measurements of the sauce and seasonings.
Tongs or Large Spoon – Useful for layering pierogies, kielbasa, and your sauce evenly in the crockpot.

Having these tools handy keeps everything organized and ensures the preparation is quick and easy.

Ingredients You’ll Need

Here’s a list of what you’ll need for this flavorful dish. These ingredients strike the right balance between creamy, smoky, and savory.

2 (12-oz) packages of pierogies (either frozen or refrigerated works)
1 lb kielbasa, sliced into bite-sized pieces
1 cup sour cream
1 (10.5-oz) can of cream of mushroom soup
1 cup shredded cheddar cheese (plus extra for garnish)

Step-By-Step Guide to Making Crockpot Pierogi Casserole

Here’s where the fun begins! Follow this simple guide for a foolproof pierogi casserole.

Crockpot Pierogi Casserole with Kielbasa

1. Prep Your Kielbasa and Onion

Slice the kielbasa into bite-sized pieces. If you’re using onions, sauté them separately in a small skillet with a bit of butter for 5 minutes until they’re translucent and fragrant.

2. Mix the Sauce

In a mixing bowl, whisk together the sour cream, cream of mushroom soup, garlic powder, salt, and pepper. Stir in 1 cup of shredded cheddar cheese for added creaminess.

3. Layer Ingredients in the Crockpot

Grab your crockpot and start layering! Begin with a single layer of pierogies, followed by sliced kielbasa, onions, and a generous amount of creamy sauce. Repeat these layers until all the ingredients are used. I usually end with a final drizzle of sauce and extra cheese on top.

4. Cook on Low Heat

Set your slow cooker on low and cook for 3-4 hours. This slow cooking allows the flavors to meld beautifully, and the pierogies become tender while absorbing the sauce.

Tips for the Perfect Crockpot Pierogi Casserole

Use High-Quality Kielbasa: The smoky, rich flavor of kielbasa is crucial for this dish. Opt for a trusted brand or consider a local butcher for the best results.
Frozen vs. Refrigerated Pierogies: Either works well for this recipe. Frozen pierogies may need a slightly longer cook time, so keep that in mind.
Cheese Options: Swap cheddar for mozzarella or Colby Jack if you prefer.
Add More Veggies: You can add chopped bell peppers, peas, or even spinach to amp up the nutrition factor.

Serving Suggestions

Once the casserole is done, your kitchen will smell amazing! Here’s how I love to serve this dish for maximum enjoyment.

Garnish with Green Onions or Parsley: A sprinkle of fresh herbs brightens the dish and adds color.
Pair with a Simple Side Salad: A fresh, crisp salad balances the richness of the casserole.
Serve Family-Style: Bring the crockpot to the table for a rustic, cozy presentation.
