Pierogi Casserole with Kielbasa Ingredients

This dish may look fancy when it comes out of the oven, but the ingredient list couldn’t be simpler. Let’s break down what you need and why each ingredient plays an important role.

Ingredient Breakdown for Pierogi Kielbasa Casserole

  • Frozen Pierogies: These dumplings, stuffed with potato and cheese, are the foundation of the casserole. You can find them in the freezer section of most grocery stores. They’re perfect because they save time while delivering all the cozy, carb-loaded goodness.
  • Kielbasa: The star of the show! Kielbasa adds a smoky, savory flavor to balance the creaminess of the pierogies. Slice it into thin rounds so every bite gets a piece of this delicious sausage.
  • Onions: Caramelized onions take this casserole to the next level. They add a subtle sweetness that complements the kielbasa beautifully.
  • Cheese: A mix of shredded cheddar and mozzarella gives the dish its gooey, cheesy topping. Cheddar brings sharpness, while mozzarella melts into a creamy, stretchy layer.
  • Heavy Cream: The cream creates a luscious sauce that ties everything together. It adds richness without making the dish overly heavy.
  • Butter: A little butter is used to sauté the onions, enhancing their flavor and giving the dish a cozy, homemade taste.

Ingredient List

Here’s exactly what you need to make this recipe:

  • 1 (16-ounce) package frozen potato and cheese pierogies
  • 1 pound kielbasa, sliced into thin rounds
  • 1 large yellow onion, thinly sliced
  • 2 tablespoons butter
  • 1 cup heavy cream
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • Fresh parsley for garnish (optional)

Step-by-Step Instructions

This pierogi casserole with kielbasa comes together in three simple steps: cooking the kielbasa and onions, layering the ingredients, and baking to perfection. Once you follow these detailed instructions, you’ll have a dish that’s not only easy to make but also worthy of rave reviews. Plus, it’s a recipe you’ll want to keep in your regular dinner rotation.

Preparing the Kielbasa and Onions

  1. Preheat the Oven: Set your oven to 375°F (190°C) to ensure it’s ready when the casserole is assembled. Lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Sauté the Onions and Kielbasa:
    • In a large skillet over medium heat, melt 2 tablespoons of butter.
    • Add the sliced onions and cook for 5-7 minutes, stirring occasionally, until they become soft and golden brown.
    • Stir in the sliced kielbasa and cook for another 5 minutes. The sausage should become slightly browned, and the onions will caramelize beautifully. Remove the skillet from the heat.
    Tip: Don’t rush the onions! Letting them caramelize slowly enhances their sweet flavor and adds depth to the casserole.

Layering Your Pierogi Casserole with Kielbasa

  1. Assemble the Casserole:
    • Place half of the frozen pierogies in a single layer at the bottom of the prepared baking dish.
    • Add half of the kielbasa and onion mixture over the pierogies.
    • Sprinkle half of the shredded cheddar and mozzarella cheese over the top.
    • Repeat with the remaining pierogies, kielbasa mixture, and shredded cheese.
  2. Pour the Cream: Slowly pour the heavy cream evenly over the layers. The cream will soak into the pierogies as they bake, creating a rich and creamy sauce.

Baking to Perfection

  1. Bake the Casserole: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes.
  2. Finish Baking Uncovered: Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
  3. Garnish and Serve: Remove the casserole from the oven and let it cool for 5 minutes. Sprinkle fresh parsley on top for a pop of color and serve warm.

Tips for the Best Pierogi Casserole

Want to take your pierogi casserole with kielbasa to the next level? If so, here are a few tried-and-true tips to make sure your dish turns out perfectly every time. With just a little extra care, you can elevate this recipe to a whole new level of deliciousness.

Choosing the Right Kielbasa

Look for high-quality kielbasa in the sausage section of your grocery store. Smoked kielbasa works particularly well in this recipe because it adds depth and flavor to the casserole without needing additional seasoning.

Substitutions and Variations

  • Add Veggies: Sneak in some vegetables like sautéed spinach, bell peppers, or mushrooms for added nutrition and flavor.
  • Cream Alternatives: If you prefer a lighter dish, swap out the heavy cream for half-and-half or a mixture of milk and cream.

Storing and Reheating Leftovers

  • Storage: Place leftovers in an airtight container and store them in the refrigerator for up to 3 days.
  • Reheating: Warm individual portions in the microwave or reheat the entire casserole in a 350°F oven until heated through.

Pairing with Side Dishes

While this casserole is hearty enough to stand alone as a full meal, pairing it with a few complementary side dishes can round things out beautifully. Here are some simple yet satisfying ideas:

  • Fresh Green Salad: A crisp salad with mixed greens, cucumbers, cherry tomatoes, and a light vinaigrette offers a refreshing contrast to the richness of the casserole. It’s also a great way to add a bright, fresh note to the meal.
  • Steamed Vegetables: First, consider pairing this casserole with steamed broccoli, green beans, or asparagus for a simple yet nutritious side dish. Not only do these vegetables add a healthy element to the meal, but they also complement the richness of the casserole beautifully. For an extra burst of flavor, try adding a sprinkle of lemon zest and a pinch of salt. This small addition enhances the vegetables with a refreshing brightness without taking attention away from the creamy and hearty main dish. Best of all, it’s a quick and effortless way to balance out the meal.
  • Roasted Vegetables: On the other hand, if you’re craving something warm and caramelized, roasted vegetables like carrots, Brussels sprouts, or zucchini are an excellent choice. A light drizzle of olive oil and a hint of garlic will enhance their natural sweetness while adding a savory depth. As a result, these veggies perfectly complement the hearty flavors of the casserole, creating a well-rounded and satisfying meal.
  • Garlic Bread: If you’re craving a little something extra, warm garlic bread or dinner rolls are perfect for scooping up every last bit of creamy sauce.

Garnishes and Toppings to Try

The right garnish can add flavor, texture, and a pop of color to your casserole. Here are a few simple toppings to try:

  • Sour Cream: A dollop of sour cream on top adds creaminess and a tangy note that balances the richness of the cheese and kielbasa.
  • Fresh Herbs: Sprinkle freshly chopped parsley, dill, or chives over the casserole for a burst of color and freshness. Dill, in particular, pairs beautifully with the potatoes and kielbasa.
  • Crispy Onions: Adding a layer of crispy fried onions as a topping brings a wonderful crunch to every bite.

FAQs about Pierogi Casserole with Kielbasa

1. What type of kielbasa works best?
Smoked kielbasa is the ideal choice for this recipe because of its robust, savory flavor. It’s fully cooked, which makes it easy to slice and incorporate into the casserole. You’ll find smoked kielbasa in most grocery stores in the sausage or deli section. If you prefer a leaner option, turkey kielbasa works just as well and still adds great flavor.

2. Can I use homemade pierogies instead of frozen ones?
Absolutely! If you have homemade pierogies on hand, they’ll make this casserole even more special. Keep in mind that frozen pierogies are slightly sturdier and hold up well during baking, so homemade ones might be a bit more delicate. To prevent homemade pierogies from breaking apart, boil them for just a minute or two before layering them in the casserole.

3. How do I make this dish ahead of time?
This casserole is an excellent make-ahead dish. Here’s how:

  • Assemble in Advance: Layer the casserole as directed but skip the baking step. Cover it tightly with foil or plastic wrap and store it in the refrigerator for up to 24 hours.
  • Bake When Ready: When you’re ready to serve, let the casserole sit at room temperature for about 15 minutes while the oven preheats. Bake as directed, adding an extra 5-10 minutes to the baking time if needed.

This method is perfect for busy days when you need dinner ready with minimal effort.

4. What cheese works well in the casserole?
Cheddar and mozzarella are a winning combination for this recipe, but there’s plenty of room for flexibility. You can try sharp white cheddar, Colby Jack, or even a little Gruyère for a nuttier flavor. Just make sure to use cheeses that melt well to get that irresistibly gooey, golden top layer.
