Step-by-step Preparation of Pierogi Casserole
Creating a delicious Pierogi Casserole doesn’t have to be complicated! Let’s guide you through each step to ensure your dish turns out creamy, cheesy, and absolutely mouthwatering.
Gather all your ingredients
Before diving in, it’s essential to have everything on hand. Here’s what you’ll need:
- 4 tablespoons (½ stick) salted butter
- 4 tablespoons all-purpose flour
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- 2 cups milk
- 2 tablespoons dijon mustard
- 4 cups shredded mozzarella cheese (divided)
- 2 (16 ounce) packages frozen pierogis
- 12 ounce package of sliced kielbasa (¼-inch thick)
- 8 ounce can of sauerkraut (drained and rinsed)
This step ensures you won't have to run around the kitchen mid-recipe. Trust me, it makes the process much smoother!
Create the creamy sauce
With everything ready, the next step is to whip up a creamy sauce. In a medium saucepan over medium heat, melt the 4 tablespoons of butter. Once melted, whisk in the flour along with the garlic powder, onion powder, salt, and black pepper. Let it cook for about a minute to combine those flavors beautifully.
Now, it’s time to add the milk. Slowly pour it in while whisking continuously to prevent lumps. After incorporating all the milk, stir in the dijon mustard. Keep whisking until the mixture comes to a gentle simmer. This is where the magic begins! Once simmering, remove it from the heat and stir in half of the shredded mozzarella until it’s all melty and delicious.
Layer the pierogis and fillings
Now for the fun part—building your pierogi casserole! Start by placing half of the frozen pierogis in an even layer at the bottom of your greased 9x13-inch baking dish. Next, generously spread half of your creamy sauce over the pierogis.
Follow this with half of the sliced kielbasa and half of the sauerkraut. Layering gives each bite tons of flavor! Repeat these layers one more time: the remaining pierogis, sauce, kielbasa, and sauerkraut. Finally, finish with the rest of that gooey mozzarella cheese on top. The more, the merrier!
Baking to perfection
Preheat your oven to 375°F. Once ready, cover your prepared casserole with nonstick foil (or foil sprayed with cooking spray) to prevent sticking. Bake for 60 minutes until bubbly, then remove the foil and bake for an additional 15 minutes to get that cheese perfectly browned and crispy.
Cooling and serving the casserole
After the baking time is up, it's crucial to let your pierogi casserole cool slightly before serving. This helps everything set up beautifully. When ready, scoop out generous portions and serve it warm, allowing everyone to enjoy this comfort food classic.

Variations on Pierogi Casserole
Vegetarian Pierogi Casserole Options
For a deliciously meat-free twist on traditional pierogi casserole, simply replace the kielbasa with a mix of your favorite vegetables! Think sautéed mushrooms, diced bell peppers, and spinach. You could also add a layer of roasted squash for sweetness. Not only does this elevate the dish, but it also makes it perfect for veggie lovers! For added flavor, consider using vegetable broth instead of milk or a plant-based cheese alternative.
Spicy Adaptations with Jalapeños
If you’re looking to kick up the heat, toss in some finely chopped jalapeños! They bring a delightful kick that perfectly complements the creamy layers of your pierogi casserole. Mix them into the sauce or sprinkle them between the layers for bursts of heat. You can even add a dash of hot sauce or crushed red pepper flakes to take the spice level up a notch. Your taste buds will thank you for this exciting twist!

Cooking Tips and Notes for Pierogi Casserole
Tips for Making the Sauce Creamy and Smooth
Achieving that perfect creamy texture in your pierogi casserole sauce is all about the technique. Whisk in the milk gradually to avoid lumps—this helps create a smooth base. Additionally, consider using whole milk for richness or even try a splash of chicken broth to add depth of flavor. For an elevated touch, you can mix in a bit of cream cheese, which melts beautifully and enhances the creaminess of your sauce.
How to Avoid Overcooking Pierogis
To ensure your pierogi casserole comes out perfectly, aim to keep your pierogis slightly undercooked before layering them in the dish. Since they’ll continue to cook in the oven, this helps prevent them from becoming mushy. If you're using frozen pierogis, there’s no need to thaw them first; simply layer them straight from the freezer. This not only saves time but also helps maintain their ideal texture during baking.
