Chicken Alfredo Pierogi Casserole
Everyone who tries this easy baked Chicken Alfredo Pierogi Casserole made from frozen pierogies raves about how amazing it is! This comfort food dinner recipe is loaded with chicken, bacon, Alfredo sauce, onions, mushrooms and pierogies.
This may be the best recipe I’ve made all year! My spouse seems to think so anyways. We’ve made this casserole bake a few times already in the last month. If you are craving comfort food, this is the recipe to try!
I even made an extra casserole so I could share it with some friends. We dropped off containers to their homes and they messaged us later on to say how delicious it was. I even was told how good of a cook I was! I had to chuckle because this recipe is so darn easy to put together that anyone can do it!
It’s creamy, savory , cheesy and filling. I think of it like a Pierogi Casserole with chicken comfort food extraordinaire.
Ingredients
If you’ve got a box of frozen pierogies (or perogies…however you spell it!) in your freezer, you can dress them up for an easy family dinner. I always buy them because they are inexpensive and good filler for nights you don’t know what to cook.
For this recipe, you’ll need the following ingredients:
- Frozen pierogies (any flavor) that have been cooked – I boiled mine per the package directions.
- Chicken
- Onion
- Mushrooms
- Cooked bacon
- Alfredo sauce – I used Classico Alfredo Sauce
- Italian seasoning
- Monterey Jack cheese – You could also use mozzarella cheese.
- Extra virgin olive oil
- Salt and pepper
How to Make
1. Preheat oven to 350F. Spread cooked pierogies on the bottom of a 9×13 casserole dish and set aside.
2. Add extra virgin olive oil to a skillet over medium heat. Add onions, mushrooms and garlic. Season with salt and pepper. Cook for approximately 10 minutes or until onions are softened and mushrooms are cooked.
3. Add Alfredo sauce to a large bowl. Add chicken, bacon, Italian seasoning and mushrooms and onion. Stir to combine. Pour on top of pierogies in casserole dish.
4. Spread cheese on top. Top with reserved bacon.
5. Bake for 30 minutes. Serve hot.

Recipe Tips
It’s easier if you prep the ingredients ahead of time. Cook the chicken breasts the night before or the morning of and store them in the fridge. Fry up extra bacon with breakfast and save some for the recipe.
Don’t cook the pierogies and leave them sit! I’ve made the mistake before of boiling the pierogies and then leaving them in the sink in the colander. They will stick together. Get them spread out in the casserole dish right after draining the water.
You can prep the entire casserole ahead of time if you like. Store in the fridge, covered, until you are ready to bake. You’ll need to add on a little extra cooking time since it’s going in the oven cold.
How to Store
Place any leftovers in covered containers or cover the casserole dish and put in the fridge. Eat within 3 days.
If you want to freeze the casserole, bake it first and then let it cool. Once cooled, place in freezer safe containers and put in the freezer for up to 3 months.

Made a few edits out of necessity. Also cooking for one so tried to reduce quantity. So it’s an inspired dish.
I’m in south MS and pierogies were none to be found! I’ve eaten them before, and have occasionally seen them in stores around MS. But it’s not popular. My first pierogies were in Prescott, Ontario and yum!
So I ended up getting potato gnocchi. I used one cooked box. I wilted a bag of spinach in the onion/mushrooms at the end. I used one can chicken bc I was being lazy. (Cooking at Airbnb isn’t the same as home) Used one jar of sauce, it seemed like enough for my reduced amount of ingredients.
But this was really yum! And something I’ll do again, especially when I see pierogies! Thanks for the idea!
Hi Natasha,
Great idea with the potato gnocchi! I’m not too far from Prescott 🙂 I’m glad to hear you enjoyed it. Thanks so much for sharing!
Can this be made and froze?
Yes, you can freeze it for up to 3 months.
My husband loved this recipe! The only problem was I bought 1 jar of Alfredo sauce and when I went to make the recipe, I realized it called for 2 jars. So I improvised by using a can of Cheddar Cheese Soup and added a bit of milk to make it the same consistency as the Alfredo sauce. Thanks for sharing the recipe, I will be making this again!!
This was exceptional. So easy to make too. Turned out wonderful. Had company over for dinner and they said it was really good.
I make homemade pierogies around the holidays. I’ve always boiled, then fried them. Think I’ll do the same for this casserole….Mmm cannot wait to try this!
i might have to try this but without the pierogies….. looks like a simple yet delicious recipe.
