Ingredients You’ll Need

These ingredients come together in such a satisfying way. The blend of cheeses with spinach and kielbasa brings balance to the dish, while using pre-made pierogi keeps things quick. When shopping, grabbing a good quality smoked kielbasa really amps up the flavor here.

• Extra-virgin olive oil: Divided, so you use some for greasing and some for drizzling, adding moisture and flavor.
• Potato pierogi: Frozen works perfectly, making prep a breeze—you can use your favorite flavor for a twist.
• Cheddar cheese soup or cream of mushroom soup: Adds creaminess and ties all the layers together.
• Cheddar cheese: Shredded; part folded into the layers and part sprinkled on top for that melty, golden crust.
• Farmer’s cheese or ricotta: Crumbled for a creamy texture that contrasts nicely with the cheddar.
• Spinach: Fresh or frozen, just make sure it’s well-drained to avoid soggy casserole.
• Yellow onion: Finely chopped or thinly sliced adds subtle sweetness.
• Smoked kielbasa sausage: Thinly sliced; gives a smoky, savory bite that pairs perfectly with the cheese and pierogi.
• Kosher salt: To season and enhance all those layers of flavors.
• Thinly sliced scallions: For a fresh, mildly sharp garnish that brightens each serving.

Variations

I love making this Pierogi Casserole Recipe my own by tweaking ingredients depending on what I have on hand. You can easily switch up the type of cheese or sausage—or even add mushrooms for an earthy touch. Don’t be afraid to get creative!

• Meat-Free Version: Swap kielbasa for sautéed mushrooms and extra spinach for a vegetarian casserole that’s just as hearty.
• Cheese Swap: Try swapping cheddar for pepper jack or gouda for a different cheesy twist—I’ve caught friends raving over smoked gouda versions!
• Extra Veggies: Feel free to add diced bell peppers or caramelized onions to boost flavor and nutrition.

How to Make Pierogi Casserole Recipe

Step 1: Get Your Oven Ready & Prepare the Base

First things first, preheat your oven to 375°F (190°C). I like to grease my baking dish with about half of the olive oil, which helps keep the casserole from sticking and adds a subtle richness. Then, lay out 12 potato pierogi in a single layer on the bottom—this base layer starts building the comforting texture that makes this dish special.

Step 2: Mix Cheese Soup and Layer Flavors

While the oven warms up, mix your canned cheddar cheese soup (or cream of mushroom) with three-quarters of the shredded cheddar cheese in a bowl. This sauce is what binds everything together and keeps the pierogi nice and creamy. Pour half of this mixture evenly over your pierogi, then crumble half of the farmer’s cheese, sprinkle half the spinach, onion, and kielbasa slices, and don’t forget a pinch of salt to balance the flavors.

Step 3: Layer It Again and Drizzle with Oil

Repeat the layering with the remaining pierogi, sauce, farmer’s cheese, spinach, onion, and sausage. Finish by topping with the rest of the cheddar cheese, seasoning lightly with salt, and drizzling the remaining olive oil on top. This last drizzle helps achieve that golden finish and keeps the top from drying out.

Step 4: Bake and Broil to Perfection

Pop the casserole in the oven and bake for about 45 minutes until it’s bubbly and cooked through. Here’s a trick I learned: When it’s done baking, switch your oven to broil and broil the top for 2-3 minutes, but watch it closely. This step crisps up the cheddar on top and gives it an irresistible golden crust that my family absolutely goes crazy for.

Step 5: Garnish and Serve

Once out of the oven, sprinkle thinly sliced scallions over the top. They add just the right touch of freshness and a little crunch that balances all the richness.

How to Serve Pierogi Casserole Recipe

Garnishes

I always top this casserole with thinly sliced scallions because they add the perfect pop of color and a fresh, slightly peppery flavor that cuts through all the rich cheese and sausage. Sometimes I like to add a dollop of sour cream on the side for an extra tangy bite that everyone appreciates.

Side Dishes

To round out the meal, I usually serve this with a simple green salad tossed in a light vinaigrette to balance the richness. Roasted Brussels sprouts or steamed green beans also pair beautifully with this casserole for a hearty yet wholesome dinner.

Creative Ways to Present

For holiday gatherings or potlucks, I like to bake this Pierogi Casserole Recipe in individual ramekins—everyone gets their own portion with a crispy top, which looks super inviting and is easy to serve. Another fun idea is layering in colorful veggies like roasted red peppers to brighten up each slice when served.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge, and they usually last 3-4 days. The casserole keeps its flavor and texture surprisingly well, making it an ideal lunch or second dinner. When you reheat, it’s best to cover it loosely with foil to avoid drying out.

Freezing

I’ve successfully frozen this casserole by baking it first, letting it cool completely, and then wrapping it tightly in plastic wrap and foil. When you’re ready to eat, thaw overnight in the fridge and then reheat in the oven until warmed through—it tastes almost as fresh as the day you made it.

Reheating

To reheat, I preheat the oven to 350°F and warm individual portions covered with foil for about 15-20 minutes. Taking a few minutes under the broiler at the end revives that crispy top and brings the casserole back to its delicious, just-baked glory.
