How To Make Pierogi Casserole
- Preheat the Oven: Start by setting your oven to 350°F (180°C).
- Prepare the Baking Dish: Grab a 9×13 inch baking dish and spray it with non-stick cooking spray to prevent sticking.
- Layer the Ingredients: Begin layering by placing half of the pierogis in the prepared baking dish. Drizzle half of the Alfredo sauce over them. Continue layering by adding half of the sliced kielbasa, then half of the scallions, and finally, half of the Colby Jack cheese. Repeat the layering with the remaining ingredients.
- Bake the Casserole: Cover the dish with aluminum foil (lightly sprayed with non-stick spray on one side to prevent sticking to the cheese). Bake for 20 minutes with the foil on. Then, remove the foil and continue baking for another 20-25 minutes, until the casserole is bubbly and slightly golden.
- Serve: Allow the casserole to cool for a few minutes after baking, then it’s ready to serve.
- Even Layers: Spread each layer evenly for consistent flavor and texture in every bite.
- Cheese Coverage: Spread the cheese evenly to ensure a gooey, melty topping.
- Foil Trick: Lightly greasing the foil prevents cheese from sticking and makes for an easier clean-up.
Storing and Reheating
- Storing: Store any leftovers in an airtight container in the fridge. They will keep well for 2-3 days.
- Reheating: Reheat in the oven at 350°F (180°C) until warm throughout. You can also reheat individual portions in the microwave, using medium power to avoid overcooking the edges.
