If you’re craving comfort food with a twist, this Traditional Pierogi Casserole is your ticket to cozy heaven. It combines the familiar flavors of pierogi in a convenient, baked dish that’s perfect for sharing with family or friends.
Lasagna noodles are the foundation of this dish, providing structure and separating the layers of filling. Mashed potatoes are the star, offering a creamy and hearty base. Shredded cheddar cheese brings a sharp, tangy richness that complements the potatoes. Sour cream adds a subtle tang and creamy texture that elevates the filling. Diced onions, sautéed until golden brown, infuse the dish with sweetness and depth. Butter is used to sauté the onions, adding flavor and richness. Finally, salt and pepper are essential for seasoning, and chopped fresh chives provide a fresh, bright finish.
This casserole pairs beautifully with a crisp green salad dressed with a light vinaigrette, balancing the richness of the dish. For a complete meal, serve with grilled sausages or roasted chicken. A glass of chilled white wine or a light beer complements the flavors nicely.
First, preheat your oven to 350°F (175°C) to get things started. Meanwhile, cook the lasagna noodles according to the package instructions, then drain them and set them aside for later. As the noodles cook, melt the butter in a skillet over medium heat. Add the diced onions and sauté them until they're golden brown and fragrant.
In a large bowl, combine the mashed potatoes, sour cream, half of the cheese, and the sautéed onions. Give it a good stir until everything is well mixed, and season with salt and pepper. Next, grease a 9x13 inch baking dish to prevent sticking.
Place a layer of noodles at the bottom of the dish, then spread half of the potato mixture over them. Repeat the layering with noodles and the remaining potato mixture, ending with a final layer of noodles. Sprinkle the remaining cheese over the top and cover the dish with foil.
Bake the casserole in the preheated oven for 30 minutes. After that, remove the foil and bake for an additional 10 minutes until the cheese on top is bubbly and golden. Once done, garnish with chopped chives before serving to add a pop of color and flavor.
