Pierogi bake casserole is a wonderfully cozy shortcut to the flavors of traditional Eastern European dumplings without the time-intensive rolling, filling, and pinching. Classic pierogi—most closely associated with Polish cuisine, but also beloved across Ukraine, Slovakia, and other parts of Central and Eastern Europe—are typically filled with potatoes, cheese, or sauerkraut and then boiled and pan-fried in butter. In this easy version, we lean on frozen pierogies, a staple in many Midwestern freezers, and layer them with a creamy, cheesy sauce and savory toppings. The result is a bubbling, golden casserole that captures the spirit of pierogi night with a fraction of the effort, perfect for busy weeknights, potlucks, or a comforting meal when the temperature drops.
This pierogi bake is rich and satisfying, so I like to balance it with something fresh and crisp on the side. A simple green salad with a sharp vinaigrette (think lemon or red wine vinegar) cuts through the creaminess nicely. Lightly sautéed or roasted vegetables—such as green beans, Brussels sprouts, or a mix of carrots and parsnips—also pair well and echo the homey feel of the casserole. For an extra nod to its Eastern European roots, serve it with a side of tangy sauerkraut or quick-pickled cucumbers. If you’re feeding a crowd, round out the table with rye bread or a crusty baguette and a small bowl of sour cream and chopped fresh dill for spooning over individual portions.
Easy Baked Pierogi Casserole with Frozen Pierogies
Servings: 6 servings
Ingredients
2 (16–20 oz) bags frozen potato-and-cheese pierogies (about 24 pierogies total)
4 tbsp unsalted butter, melted (plus extra for greasing the dish)
1 medium yellow onion, thinly sliced
6 slices bacon, chopped (optional but traditional and flavorful)
2 cloves garlic, minced
1 1/2 cups sour cream (full-fat recommended)
1 cup heavy cream or half-and-half
1 1/2 cups shredded sharp cheddar cheese, divided
1/2 cup shredded mozzarella cheese (optional, for extra meltiness)
1 tsp kosher salt, plus more to taste
1/2 tsp freshly ground black pepper
1/2 tsp smoked paprika or sweet paprika
1 tbsp chopped fresh chives or green onions, plus extra for garnish
2 tbsp chopped fresh parsley or dill, plus extra for garnish
Directions
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
Cook the bacon: In a large skillet over medium heat, cook the chopped bacon until crisp and browned, 6–8 minutes. Transfer the bacon to a paper towel–lined plate, leaving about 1–2 tablespoons of rendered fat in the skillet. If not using bacon, add 1–2 tablespoons of butter or neutral oil to the skillet instead.
Sauté the aromatics: Add the sliced onion to the skillet with the bacon fat (or butter/oil). Cook over medium heat, stirring occasionally, until the onion is soft and lightly caramelized around the edges, about 8–10 minutes. Add the minced garlic and cook for 30–60 seconds, just until fragrant. Remove from heat.
Make the creamy sauce: In a medium bowl, whisk together the sour cream, heavy cream or half-and-half, melted butter, salt, pepper, and paprika until smooth. Stir in about 1 cup of the shredded cheddar cheese and the mozzarella cheese, if using, along with the chopped chives and parsley or dill.
