Ingredients You’ll Need

The mix of pierogi, cheeses, spinach, and smoked kielbasa sausage packs this Pierogi Casserole Recipe with flavor and texture—plus, it balances creamy and savory beautifully. When shopping, picking good-quality pierogi and fresh spinach really lifts the dish.

• Extra-virgin olive oil: Use it for greasing the dish and a little drizzle on top to help develop that perfect crust.
• Potato pierogi (or favorite frozen flavor): These are the star! I like potato, but cheese or sauerkraut versions work great too.
• Cheddar cheese soup (or cream of mushroom soup): Adds creamy body and flavor; the soup acts like a binder here.
• Shredded cheddar cheese: For that gorgeous melty top and cheesy goodness throughout.
• Farmer’s cheese or ricotta: Gives a lovely creamy tang and richness that balances the smoky sausage.
• Fresh or frozen spinach: Make sure it’s well-thawed and drained to avoid watery casserole layers.
• Yellow onion: Finely chopped or thinly sliced to add a mild sweetness and texture.
• Smoked kielbasa sausage: Thin slices bring smoky, meaty flavor that complements the cheese and pierogi perfectly.
• Kosher salt: Season layers as you go to build flavor.
• Thinly sliced scallions: Fresh green garnish for brightness and a bit of crunch at the end.

Variations

I like to play around with this Pierogi Casserole Recipe depending on what we have on hand or dietary needs. It’s a flexible recipe that invites creativity, so don’t hesitate to swap or add your favorite veggies or swap meats.

• Vegetarian option: Skip the kielbasa and add mushrooms, bell peppers, or more spinach—this keeps the casserole hearty and satisfying.
• Cheese swaps: I’ve used mozzarella or gouda instead of cheddar for a milder, creamier flavor that my kids love.
• Spicy kick: Sometimes I add a pinch of smoked paprika or cayenne to the sausage layer for a subtle heat that wakes up the dish.
• Different pierogi: Sauerkraut or mushroom pierogi can add an earthier note if you want to experiment.

How to Make Pierogi Casserole Recipe

Step 1: Prep Your Baking Dish and Pierogi

First things first, preheat your oven to 375°F. Grab a 13 x 9-inch (or similar) baking dish and grease it really well with a tablespoon of olive oil. Then, arrange about 12 pierogi in a single layer to cover the bottom—don’t worry if they overlap slightly; this forms the casserole base. I find greasing well prevents sticking and helps get that golden crust on the pierogi edges.

Step 2: Layer the Savory Mixture

In a medium bowl, mix the cheddar cheese soup with three-quarters of the shredded cheddar. This mixture is your creamy glue! Pour half over the pierogi layer, then crumble half the farmer’s cheese on top. Sprinkle half the spinach, half the finely chopped onion, and half the sliced kielbasa over everything. Don’t forget to season lightly with kosher salt. This layering is key because it helps balance creamy, cheesy, and meaty flavors in every bite.

Step 3: Repeat and Finish

Now, repeat that layering with the remaining pierogi and the rest of your soup-cheese mixture, farmer’s cheese, spinach, onion, and sausage. Top the entire casserole with the remaining cheddar cheese and another light sprinkle of salt. Drizzle the last tablespoon of olive oil over the top to encourage browning and a bit of crispness.

Step 4: Bake and Broil to Perfection

Bake your casserole for about 45 minutes, until everything is bubbly and heated through. I’m always so tempted to peek in early, but trust me—patience really pays off here. Once baked, switch your oven to broil and watch closely as the top crisps up in 2-3 minutes. That gorgeous golden-brown cheese topping is the best part!

Step 5: Garnish and Serve

Finish by scattering thinly sliced scallions over the top for a fresh pop of color and flavor. I like this bit of brightness because the casserole itself is so rich and rich, the scallions cut through perfectly.

How to Serve Pierogi Casserole Recipe

Garnishes

I love topping mine with fresh scallions or a sprinkle of crispy fried onions to add texture and a touch of sharpness to the rich casserole. Sometimes a dollop of sour cream on the side makes it feel extra indulgent, too.

Side Dishes

This casserole pairs wonderfully with a simple green salad dressed in vinaigrette to balance the creaminess. Roasted vegetables or a crisp cucumber salad also add freshness and crunch that complement the warm, cheesy layers.

Creative Ways to Present

For special occasions, I’ve set this casserole in individual ramekins for a pretty presentation at dinner parties. You could also layer it in a pretty glass casserole dish so guests see those beautiful layers through the sides—it always gets compliments!

Make Ahead and Storage

Storing Leftovers

I usually let leftovers cool to room temperature, then store them tightly covered in the fridge for up to 3 days. The flavors actually deepen overnight, making the next-day meal even better.

Freezing

This Pierogi Casserole Recipe freezes really well! I assemble it, but don’t bake, then tightly cover with foil and freeze. When ready to eat, I bake it from frozen, adding extra time to make sure it’s heated through.

Reheating

To reheat, I recommend the oven for best texture—cover loosely with foil and warm at 350°F until hot, about 20 minutes. You can finish with a quick broil if you want to crisp up the top again. Microwaving works in a pinch but tends to make it softer.
