Ingredients for Easy Pierogi Sausage Casserole

Gathering the right ingredients is the first step to culinary success, and this Easy Pierogi Sausage Casserole features some fantastic staples that create a cozy meal. Here’s what you’ll need to gather:

Frozen Potato and Cheese Pierogies: These little pockets of joy are the star of the show! They save you time while still delivering that comforting flavor.
Smoked Kielbasa: This sausage adds a rich, smoky flavor that beautifully complements the dish. You can opt for turkey or veggie kielbasa for a lighter or meat-free variation.
Condensed Cream of Mushroom Soup: This canned gem provides a creamy base for the casserole. It’s a shortcut for homemade sauces without sacrificing flavor.
Sour Cream: Adds a tangy creaminess that elevates the overall taste. You can swap it with Greek yogurt for a healthier twist.
Shredded Cheddar Cheese: I use sharp cheddar for a bold flavor. Feel free to mix in other cheeses like mozzarella for extra gooeyness!
Milk (optional): If you prefer a thinner sauce, this ingredient can help achieve the desired consistency. Adjust according to your taste.
Medium Onion: Adds sweetness and depth when sautéed. Yellow or white onions will work beautifully here.
Olive Oil: Just a splash to cook the kielbasa and onions. You can use any cooking oil you have on hand.
Salt and Pepper: Essential seasonings that bring all the flavors together. Adjust them to your preference for additional seasoning.
Chopped Fresh Parsley (optional): Sprinkle some on top for a fresh touch and burst of color. If you don’t have fresh parsley, dried herbs work, too.

How to Make Easy Pierogi Sausage Casserole

Now that we’ve gathered our ingredients, it’s time to roll up our sleeves and get cooking! Follow these simple steps to create your Easy Pierogi Sausage Casserole. Trust me; it’ll be worth every minute!

Step 1: Preheat the Oven and Prepare the Dish

First things first! Preheat your oven to 350°F. This way, your casserole will bake evenly. While the oven warms up, grab a 9×13 inch casserole dish. Grease it with some olive oil or nonstick spray. This will help your casserole slide right out when it’s ready.

Step 2: Cook the Kielbasa

Next, let’s get that kielbasa sizzling! In a large skillet, heat a tablespoon of olive oil over medium heat. Add the sliced kielbasa in a single layer. Cook for about 4 to 6 minutes. You want the edges to turn a lovely, golden brown. This step adds depth to the flavors! Once browned, use a slotted spoon to remove it. Set it aside for now.

Step 3: Sauté the Onions

In the same skillet, drop in your thinly sliced onion. It’s time to bring out its sweetness! Sauté for 4 to 6 minutes until the onion has softened and caramelized slightly. Sprinkle a pinch of salt and pepper over them for extra flavor. Once they’re looking good, remove them from the heat.

Step 4: Mix the Sauce

In a medium bowl, combine the condensed cream of mushroom soup, sour cream, and milk if you’re using it. Whisk until it’s smooth and creamy. You want this sauce to be velvety! Season generously with salt and pepper to your taste. Remember, this sauce is the heart of our Easy Pierogi Sausage Casserole!

Step 5: Layer the Casserole

Now it’s time for the fun part—layering! Start with half of the frozen pierogies, placing them evenly across the bottom of the prepared casserole dish. Then, scatter half the browned kielbasa on top, followed by half the sautéed onions. Spoon half of our creamy sauce over this layer. Don’t be shy—let it drizzle down every last pocket! Finally, add 1 cup of shredded cheddar cheese across the top. Repeat this process with the remaining ingredients.

Step 6: Bake the Casserole

Time to let the oven work its magic! Cover your casserole dish tightly with aluminum foil. Bake in the preheated oven for 25 minutes. After that, carefully remove the foil and sprinkle the last cup of cheddar cheese on top. Bake for an additional 10 to 15 minutes until cheese is melted and bubbly. If you like a bit of color, pop it under the broiler for a minute or two, but keep a close eye on it!

Step 7: Serve and Enjoy

Once it’s out of the oven, allow the casserole to rest for about 5 minutes. This will help everything settle into deliciousness. For a pretty presentation, garnish with fresh parsley if you have it. Serve with a dollop of sour cream on top if desired, and watch everyone dig in!

Tips for Success

Ensure the pierogies are frozen—no need to thaw for perfect texture!
For a more golden top, broil for a minute or two after baking.
Don’t skip the resting time; it helps flavors meld together.
Experiment with different cheeses for a unique flavor profile.
Feel free to sneak in veggies like spinach or bell peppers for added nutrition!

Equipment Needed

9×13 inch casserole dish: You can also use an 8×8 inch dish for a thicker casserole.
Large skillet: Any frying pan will do—just make sure it’s deep enough for sautéing.
Medium mixing bowl: A large enough bowl to whisk your sauce ingredients together.
Slotted spoon: Perfect for removing kielbasa without the grease.
Aluminum foil: Essential for covering the casserole while baking.

Variations

Vegetarian Option: Substitute the smoked kielbasa with veggie sausage or mushrooms for a delicious meat-free alternative.
Different Cheeses: Try using a blend of mozzarella and Monterey Jack for a gooey texture or even add feta for a tangy twist.
Extra Veggies: Add in frozen peas, spinach, or bell peppers to the layers for additional nutrients and a pop of color.
Spice it Up: For a kick, sprinkle some red pepper flakes or use spicy kielbasa to heat things up.
Gluten-Free Alternative: Use gluten-free pierogies and ensure your cream of mushroom soup is gluten-free as well for a suitable option.

Serving Suggestions

Fresh Salad: Pair your casserole with a crisp green salad dressed with a light vinaigrette for a refreshing contrast.
Garlic Bread: Serve with warm garlic bread or dinner rolls to soak up that creamy sauce.
Wine: A chilled white wine like Riesling or a light red complements the hearty flavors beautifully.
Garnish: A sprinkle of fresh parsley or chives adds a nice touch and color.
