What You’ll Need (Ingredient Highlights)
Frozen cheddar pierogies – the heart of the dish, soft and cheesy.

Pro Tips Before You Start
No need to thaw the pierogies. Just layer them in frozen—they’ll cook perfectly in the oven.
Grease your foil. This prevents the cheese from sticking to the top.
Use pre-shredded cheese to save time, or grate your own for extra meltiness.
Add a dash of garlic powder or red pepper flakes for a flavor kick.
How to Make Creamy Baked Pierogi Casserole
Step 1: Prep your baking dish
Preheat the oven to 350ºF (177ºC).
Lightly grease a 9×13-inch casserole dish.
Also, spray one side of a piece of aluminum foil with nonstick spray and set aside.
Step 2: Start layering
Place half of the frozen pierogies in a single layer in the baking dish.

Spoon Alfredo sauce over the pierogies.
Layer with sausage slices, sprinkle with green onions, and then top with both types of shredded cheese.
Step 4: Repeat
Add a second round of pierogies, Alfredo sauce, sausage, green onions, and cheese.
Step 5: Bake covered
Cover the dish with the greased foil and bake for 20 minutes.
Step 6: Bake uncovered
Remove the foil and continue baking for another 20–25 minutes, or until the casserole is bubbly and golden.
Step 7: Rest and serve
Let the dish rest for 5 minutes before slicing and serving warm.
