A Brief History of Pierogi & Alfredo Sauce

Pierogi originated in Central and Eastern Europe, where they have been a beloved comfort food for centuries. Traditionally, pierogi are stuffed with potatoes, cheese, or meat and served with butter or sour cream. Today, they’re widely enjoyed in North America, often with modern twists like this Alfredo casserole. Learn more about pierogi history and their cultural significance.

On the other hand, Alfredo sauce traces its roots to Italy. The original version, known as Fettuccine Alfredo, was created by Alfredo di Lelio in the early 1900s. Unlike its modern creamy counterpart, the traditional sauce consisted of butter and Parmesan cheese. Over time, the recipe evolved into the creamy, garlic-infused sauce that’s popular today.

Frozen Pierogi (16 oz package) – Traditional potato and cheese pierogi work best, but you can also use bacon, mushroom, or spinach-stuffed pierogi for extra flavor.
Cooked Chicken (2 cups, shredded) – Rotisserie chicken is a convenient option, but grilled or baked chicken also works well.

Step-by-Step Cooking Instructions

Making this Chicken Alfredo Pierogi Casserole is incredibly simple. Just layer the ingredients, bake, and enjoy! Follow these detailed steps for a perfect, creamy, and cheesy casserole.

Step 1: Prepare the Baking Dish

Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
This step is crucial for even baking and ensures the pierogi don’t dry out.

Step 2: Arrange the Frozen Pierogi

Place the frozen pierogi in a single layer in the prepared baking dish.
If you’re using different flavors (cheese, potato, bacon, etc.), mix them for variety.
No need to thaw the pierogi beforehand—they’ll cook perfectly in the oven.

Step 3: Prepare the Alfredo Chicken Mixture

In a medium-sized bowl, combine the following ingredients:
- Shredded cooked chicken (2 cups)
- Alfredo sauce (15 oz jar)
- Milk (½ cup) to thin the sauce for even distribution
- Garlic powder (½ teaspoon)
- Onion powder (½ teaspoon)
- Italian seasoning (½ teaspoon)
- Black pepper (¼ teaspoon)
Stir everything together until well combined. This mixture should be thick but pourable.

Sprinkle shredded mozzarella cheese (1 cup) evenly over the top.
Add grated Parmesan cheese (½ cup) for extra richness.

Step 5: Bake the Casserole

Cover the dish with aluminum foil and bake for 25 minutes.
The foil helps trap moisture, preventing the dish from drying out.

Step 6: Remove the Foil & Finish Baking

After 25 minutes, remove the foil.
Bake uncovered for an additional 10-15 minutes, or until the cheese is melted and bubbly.
If you prefer a crispy, golden top, broil the casserole for 2-3 minutes at the end.

Step 7: Let It Rest & Serve

Remove the casserole from the oven and let it rest for 5 minutes before serving.
Garnish with chopped fresh parsley for a pop of color and freshness.
Serve hot and enjoy this creamy, cheesy comfort food!
