Looking for an easy, comforting & super simple dinner idea? Check out this tasty chicken pot pie casserole.

I like to describe this dish as a combination between a chicken pot pie and Shepard's pie. Think of the classic pot pie filling you know and love but topped with delicious whipped mashed potatoes. I'm not the biggest fan the puff pastry that comes on top of the traditional pot pie so this is a nice alternative to still get those flavours with a bit of a different spin icon

This recipe uses simple pantry ingredients to make this hearty dish. It requires nothing fancy and pretty simple kitchen skills but boy oh boy does it really hit the spot!

For the mashed potatoes
In a large pot, place diced potatoes and cover with enough cold water to submerge the potatoes. Boil over high heat until fork tender, about 20 minutes. Drain and add back to large pot.
To the cooked potatoes, add in butter. Using a hand held mixer, beat potatoes and butter together.

Season with salt and pepper, cover with the lid and set aside.
For the chicken pot pie
In a large frying pan over medium high heat, add oil, carrots, corn, peas, mushrooms and onions and cook until tender, about 8-10 minutes. Once cooked through, remove and place in large mixing bowl.
To the cooked vegetables, add in diced chicken and stir.
Next add in soup, sour cream and milk. Stir to combine and season to your liking.
To assemble
Preheat oven to 400.
Place pot pie mixture in large 9 X 13 baking pan.

Bake uncovered for 10-15 minutes or until top is getting golden brown. Serve warm and en

    Does this have a crust? Or just mashed potatoes as crust on pot pie?

      Hi; there is no crust. It is a chicken pot pie casserole topped with mashed potatoes.

    This looks delicious. I have started using cream of chicken with herbs in these kinds of recipes. It makes it even easier to “season to taste.”

      Thanks, Beth! That is a great tip I’ll need to check for that next time I’m getting groceries 😊
