How to make Easy Pierogi Sausage Casserole

Making Easy Pierogi Sausage Casserole is straightforward, even for beginner cooks. The dish comes together in a few simple steps, allowing you to enjoy a home-cooked meal without much hassle. Here’s how to make it.

Ingredients

To make this delicious casserole, you will need the following ingredients:

24 oz frozen potato and cheese pierogies
1 lb smoked kielbasa, sliced into rounds
1 can (10.5 oz) condensed cream of mushroom soup
½ cup sour cream
2 cups shredded cheddar cheese, divided
½ cup milk (optional, to thin sauce)
1 medium onion, thinly sliced
2 tablespoons chopped fresh parsley (optional for garnish)
1 tablespoon olive oil
Salt, to taste
Freshly ground black pepper, to taste

Directions

Preheat the oven to 350°F (175°C). Grease a 9×13 inch casserole dish with oil or nonstick spray.
Cook the Kielbasa: In a large skillet, heat olive oil over medium heat. Add the sliced kielbasa and cook until the edges are lightly browned, about 4 to 6 minutes. Use a slotted spoon to remove the kielbasa and set it aside.
Sauté the Onion: In the same skillet, add the sliced onion. Sauté for 4 to 6 minutes until the onion is softened and begins to caramelize. Season it lightly with salt and pepper. Remove from heat.
Make the Sauce: In a medium bowl, whisk together the condensed cream of mushroom soup, sour cream, and milk until smooth. Adjust the milk quantity if you want a thinner sauce. Season with salt and pepper to taste.
Layer the Casserole: Arrange half of the frozen pierogies in an even layer in the greased casserole dish. You do not need to thaw them. Scatter half of the browned sausage and half of the sautéed onions over the pierogies. Spoon half of the sauce mixture evenly on top. Finally, sprinkle 1 cup of shredded cheddar cheese over this layer.
Repeat Layers: Repeat the process with the remaining pierogies, sausage, onions, and sauce. Top everything with the last cup of shredded cheddar cheese.
Bake: Cover the dish tightly with aluminum foil and bake for 25 minutes in the preheated oven.
Final Browning: Remove the foil and bake for an additional 10 to 15 minutes until the cheese is melted, bubbly, and the top is golden. If you want extra browning, you can broil it for 1 to 2 minutes, but watch it closely to avoid burning.
Rest and Serve: Allow the casserole to rest for 5 minutes before serving. Garnish with chopped fresh parsley and serve with optional sour cream.

Tips and Mistakes to Avoid

Here are a few tips to ensure your Easy Pierogi Sausage Casserole turns out perfect:

Don’t Thaw the Pierogies: Baking them directly from frozen helps keep the texture nice and firm, avoiding mushiness.
Watch the Cooking Time: Ovens can vary in temperature, so check the casserole a few minutes early. You want the cheese melted and golden without overcooking the dish.
Adjust Sauce Consistency: Depending on your preference, feel free to adjust the milk in the sauce. If you like it creamier, use less milk; if you prefer it thinner, add more.
Sauté Onions Well: Make sure your onions are slightly caramelized before adding them to the casserole for added sweetness and depth of flavor.

Variation

There are plenty of variations you can try with this Easy Pierogi Sausage Casserole:

Vegetarian Option: Swap kielbasa with mushrooms, bell peppers, or zucchini for a vegetarian dish.
Different Cheese: Use different types of cheese such as mozzarella or pepper jack for a more unique flavor.
Add Vegetables: To boost the nutritional value, add spinach or kale to the layers.
Use Different Sauces: Experiment with different soup bases, like cream of chicken or cheese soup.

FAQs

1. Can I use homemade pierogies instead of frozen?
