Step‑by‑Step Instructions for Cheesy Pierogi Casserole Step 1: Preheat and Prepare Begin by preheating your oven to 375°F (190°C). While it heats, take a moment to grease a 9×13 inch baking dish with non-stick spray or butter. This ensures easy serving and cleanup later. The warmth of your oven will soon fill the kitchen with delicious aromas as the Cheesy Pierogi Casserole bakes. Step 2: First Layer of Pierogies Once the dish is ready, layer half of the frozen cheddar cheese pierogies on the bottom, arranging them evenly. There’s no need to defrost, as they will cook beautifully in the oven. Place them snugly to create a solid foundation for your casserole, making sure they’re flat and evenly distributed. Step 3: Add Alfredo Sauce Spread half of the alfredo sauce generously over the first layer of pierogies, ensuring every dumpling is well-coated. This creamy goodness will soak into the pierogies as they bake, imbuing them with flavor. The rich, velvety consistency of the sauce is crucial for achieving the ultimate cheesy comfort that this Cheesy Pierogi Casserole promises. Step 4: Sprinkle Toppings Now, sprinkle half of the crispy cooked bacon, followed by half of the sliced green onions, evenly across the sauced pierogies. The bacon adds a delightful crunch, while the green onions introduce a fresh, mild flavor that brightens the dish. Finally, layer half of the shredded mozzarella and cheddar cheese generously on top for that golden finish. Step 5: Repeat the Layers Next, repeat the layering process with the remaining frozen pierogies, sauce, bacon, green onions, and cheeses. Ensure that everything is evenly spread to maintain a balanced flavor throughout the Cheesy Pierogi Casserole. Don’t forget to season with kosher salt and black pepper to enhance all the rich flavors. Step 6: Bake Covered Cover the casserole dish tightly with aluminum foil and place it in the preheated oven. Bake for 15 minutes to allow the pierogies to steam and soften. This step ensures that the entire dish heats through, creating that comforting and hearty texture that we love in a casserole. Step 7: Bake Uncovered After 15 minutes, carefully remove the foil and continue to bake the Cheesy Pierogi Casserole for an additional 20-25 minutes, or until the dish is bubbling and the cheese is beautifully melted and golden brown. The savory aroma wafting from the oven will surely entice everyone in your home! Step 8: Garnish and Serve Once the casserole is done baking, take it out of the oven and let it rest for a few moments. Before serving, sprinkle freshly chopped parsley over the top for a vibrant touch of color and freshness. Now your Cheesy Pierogi Casserole is ready to be served and enjoyed!

Cheesy Pierogi Casserole Recipe FAQs What kind of pierogies should I use? For this Cheesy Pierogi Casserole, I recommend using frozen cheddar cheese pierogies. They provide the perfect flavor base for the dish, and there’s no need to defrost them beforehand—just layer them straight from the freezer! How do I store the leftovers? Leftovers can be stored in an airtight container in the fridge for up to 4 days. I often enjoy reheating them in the microwave at reduced power to keep them nice and creamy without drying out. Can I freeze Cheesy Pierogi Casserole? Absolutely! To freeze, allow the casserole to cool completely after baking. Then, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and reheat it at 350°F (175°C) until warmed through (about 30 minutes). What are some common issues when making this casserole? If your pierogies turn out a bit tough, it might be because they weren’t steamed enough at the beginning. Make sure to cover the dish with foil for the first 15 minutes of baking to create steam. Also, uneven layering can lead to some bites tasting less flavorful. Be sure to distribute the sauce, toppings, and pierogies evenly for the best results! Are there any dietary considerations I should be aware of? This casserole contains dairy and gluten from the pierogies and cheeses, so it may not be suitable for those with lactose intolerance or gluten sensitivities. If you’re feeding a crowd, consider using gluten-free pierogies and a dairy-free cheese alternative to make this dish more inclusive for different dietary needs. Can I add vegetables to the casserole? Very much! Adding vegetables not only boosts nutrition but also adds vibrant color. I suggest incorporating sautéed spinach or diced tomatoes between the layers for an extra flavor twist. Just be sure to keep the moisture in check to avoid a soggy casserole!
