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.
  • 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

Variations

  • Broccoli – Add some broccoli florets when you’re cooking the mushrooms and onions.
  • Ham – Use leftover ham instead of bacon.
  • Vegetarian – Leave the chicken and bacon out of the recipe. Add in some extra veggies if you like.
  • Cheese – Add more cheese like Parmesan and mozzarella.
  • Spinach – Add spinach in with the onions and mushrooms.

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.
