This pierogi puff pastry pizza is the ultimate comfort food. It hits all the nostalgic notes of old-school pierogi pizza: a layer of cheesy mashed potatoes on a flaky puff pastry crust, finished with sweet, caramelized onions.
Yes — potatoes on pizza, and it works beautifully.
The base is the fluffiest cheesy mashed potatoes, with extra cheddar folded in, and the caramelized onions on top add a sweet-savory finish. It’s hearty, comforting, and perfect for chilly nights or a special Lent Friday dinner.
I’ve made a traditional pierogi pizza before on classic pizza dough, which is wonderful, but heavier. Switching to puff pastry makes this version lighter, flakier, and more balanced alongside the cheese-and-potato topping.
If pierogis remind you of fish fry Fridays and Lent traditions, this will transport you there in a new form. If you’ve never had pierogi pizza before, think of this as cheesy mashed potatoes on a crispy, flaky crust — and yes, it’s delicious.
Many pierogi lovers prefer the classic dumpling filled with mashed potatoes and cheese. For this pizza, the potato-cheese mixture becomes the topping, and caramelized onions are cooked separately and added on top for extra flavor and texture.
Caramelized onions are worth the time — they deepen the flavor and pair perfectly with the cheesy potatoes.
A few steps are involved: caramelize the onions, make a small batch of mashed potatoes (or use leftovers), and then assemble on a sheet of puff pastry. The mashed potatoes are spread thinly, topped with mozzarella, and baked until the pastry is golden and puffed. Finish with the caramelized onions and fresh herbs.
A little effort, big reward
Yes, this recipe requires a bit of prep, but the results are worth it. Caramelizing onions takes time but gives a rich, sweet finish. Making fresh mashed potatoes gives you control over texture and seasoning, and the puff pastry keeps the dish light and flaky compared to a dense pizza crust.
Serve this as a main, a side, or a party snack. Slice it into smaller pieces for sharing. You can also add classic pierogi toppings like sour cream, green onions, or bacon to customize each slice.
Puff pastry is my preference here because it’s lighter, flakier, and thinner than traditional pizza dough, making the mashed potato topping feel less heavy while still delivering the familiar pierogi flavors.

Ingredients
- 2 tablespoons olive oil
- 3 sweet onions, thinly sliced
- kosher salt and pepper
- 1 pound yukon gold potatoes, peeled and chopped
- ⅔ cup heavy cream
- 6 tablespoons butter
- 4 ounces grated cheddar cheese
- 4 ounces grated mozzarella cheese
- 1 sheet puff pastry, refrigerated or frozen
- 1 large egg + 1 teaspoon water, beaten for egg wash
- chives or fresh herbs for topping
Instructions
-
Preheat the oven to 425°F (220°C).
-
Heat the olive oil in a large skillet over medium heat. Add the sliced onions with a pinch of salt and cook, stirring occasionally, until they begin to soften, about 15–20 minutes. Lower the heat and continue to cook, stirring often, until the onions are deeply golden and caramelized, about 45–60 more minutes.
-
While the onions cook, make the mashed potatoes. Place the chopped potatoes in a pot of cold water, bring to a boil, and cook until fork-tender, about 10–15 minutes. Drain well.
-
Return the pot to low heat and add the cream and butter so they warm and melt. Add the drained potatoes back to the pot and mash until smooth. Season with salt and pepper, then stir in the grated cheddar until evenly combined.
-
Place the puff pastry sheet on a parchment-lined baking sheet and prick the surface all over with a fork. Spread a thin, even layer of mashed potatoes over the pastry, leaving a 1-inch border. Sprinkle the mozzarella over the potatoes and brush the pastry edge with the egg wash.
-
Bake for 15–20 minutes, or until the pastry is puffed and golden and the cheese is melted.
-
Remove from the oven and scatter the caramelized onions over the top. Garnish with chives or fresh herbs, slice, and serve immediately.
