Chicken Alfredo Pierogi Casserole at a Glance

Ingredients You Will Need

This recipe relies on simple, readily available ingredients, many of which are pantry staples, making it an incredibly accessible meal.

• 2 lbs frozen pierogies (fully thawed is key! Bacon and cheese flavor works wonders, but any type is fine)
• 2 cups cooked chicken, shredded or chopped (Rotisserie chicken works great!)
• 10 slices bacon, cooked and crumbled (or substitute with pre-cooked bacon pieces/bits)
• 2 cups shredded mozzarella cheese (plus extra for a richer top)
• 2 Jars of Alfredo sauce (about 15 oz jars each)

Optional Flavor Boosters:

• 1/2 cup chopped onion or mushrooms
• 1 tsp minced garlic
• Black pepper or Italian seasoning to taste

Step-by-Step Instructions

Follow these simple steps to create a cheesy, bubbly, and rich bacon pierogi casserole that is perfect for any occasion.

1. Preparation and Sautéing

• Preheat the Oven: Preheat your oven to 350°F (175°C).
• Cook the Bacon: In a large skillet, cook the bacon until perfectly crispy. Remove the bacon, crumble it, and set it aside.
• Optional Sauté: If you are adding vegetables, save 1-2 tablespoons of the bacon drippings in the skillet. Sauté the chopped onion, mushrooms, and garlic until softened (about 5 minutes).

2. Assemble the Casserole

• Prep the Dish: Lightly grease a standard 9×13-inch casserole dish.
• Layer the Pierogies: Arrange the thawed pierogies in a single layer across the bottom of the prepared dish.
• Add Meat & Flavor: Sprinkle the cooked, shredded chicken, the crumbled bacon, and any sautéed vegetables (if using) evenly over the pierogies.
• Pour the Sauce: Pour both jars of Alfredo sauce over the entire mixture, ensuring that the pierogies are well coated.
• Top it Off: Sprinkle the shredded mozzarella cheese generously over the top layer.

3. Bake and Serve

• Bake Covered: Cover the dish loosely with aluminum foil. Bake for 40–45 minutes, or until the sauce is bubbly and the pierogies are soft.
• Achieve Golden Brown: If you prefer a beautifully browned, crusty mozzarella top, remove the foil during the last 5 minutes of baking, or briefly broil on high for 2–3 minutes (watch carefully to prevent burning).
• Rest: Let the chicken and pierogi bake rest for 5–10 minutes before serving. This allows the sauce to set slightly, making serving easier.
• Garnish: Garnish with fresh chopped parsley if desired, and serve hot!

Why This Chicken Alfredo Pierogi Bake is a Weeknight Winner

This recipe is designed for maximum flavor and minimum fuss, making it ideal for busy families looking for a hearty comfort food dinner that can be prepped quickly.

Time Savings is Key: The use of frozen pierogies and jarred Alfredo sauce cuts preparation time dramatically. If you opt for a store-bought rotisserie chicken, you can eliminate cooking the chicken entirely, bringing your hands-on prep time down to under 15 minutes.

Perfect Texture: The combination of ingredients creates a textural masterpiece: the soft, pillowy potato and cheese pierogies absorb the creamy Alfredo sauce while the mozzarella melts into a sublime, gooey blanket, contrasted perfectly by the crunch of bacon.

Customization Potential: Unlike many rigid recipes, this pierogi casserole is highly adaptable. It provides a simple base that you can quickly adjust based on what you have available or what flavors your family loves. This versatility is what truly makes it a staple easy pierogi dinner recipe.

Expert Tips for Customizing Your Comfort Casserole

One of the best features of this mozzarella and chicken casserole is how easily it adapts to your palate and pantry. Use these tips to optimize your baking experience and flavor profile:

Meat Substitutions & Add-Ins

• Chicken Alternatives: While shredded chicken is classic, this recipe is delicious with other cooked proteins. Try using leftover fried beef, crumbled Italian sausage, or cubed leftover ham for a different flavor profile.
• Vegetarian Option: Skip the bacon and chicken and double down on vegetables. Sautéing spinach, zucchini, and mushrooms adds great texture and depth. Ensure your selected pierogies are cheese and potato only.

Sauce and Flavor Boosts

• Enhance Creaminess: For an extra decadent sauce, stir in a splash of heavy cream or 2 ounces of softened cream cheese directly into the Alfredo sauce before pouring it over the pierogies.
• Garlicky Ranch Twist: To add a subtle tang, stir 1/4 cup of ranch dressing or 1 teaspoon of garlic powder into the jarred Alfredo sauce. This gives the sauce a delightful garlic-herb complexity.
• Hidden Veggies: Easily incorporate nutrition by adding steamed broccoli florets or a handful of fresh spinach underneath the cheese layer.

Make-Ahead and Storage

This recipe is excellent for meal prepping and freezing!

• Make-Ahead Assembly: Assemble the entire casserole (up to the point of baking) up to 24 hours in advance. Cover tightly and refrigerate. When ready to bake, you may need to add 5–10 minutes to the total cook time since the dish will be cold.
• Freezing Baked Leftovers: Leftovers store well in an airtight container for up to 3 days in the refrigerator. To reheat and preserve moisture, cover the dish and warm in a moderate 300°F oven until heated through.
• Freezing Unbaked: While possible, freezing assembled pierogies can sometimes make the potatoes slightly mushy upon thawing. It is best to assemble this dish fresh or refrigerate only for the specified 24 hours.
