My Southern kitchen is always cooking up hearty comfort food, and chicken pot pie is a classic dish that delivers! There is something with true comfort foods like chicken and dumplings and fluffy buttermilk biscuits and sausage gravy that just bring you back home and warm your soul. Or fuel your soul.......get it..... wink wink..... ok I am done lol. 😉

Chicken pot pie can be made with different types of "cream of whatever" cans of soup depending on which recipe you find or grow up with. But I just like to stay away from processed foods, so I tested this a bunch of different times to figure out how to get that same luscious cream chicken and veggie filling but with fewer ingredients - my updated and modern take on Southern cooking! Let me show you how.

Step by Step on How To Make

sautéing celery in a big pot on the stove with some butter.
Saute the onions and celery in a large pot over medium heat with the butter for a couple of minutes until soft.
Add flouring to onions and celery and cooking in a pot on the stove.
Add in the flour and stir to coat the veggies. Cook for a couple of minutes. The flour will help thicken the filling.
Cooking chicken broth, milk, and veggies in a pot on the stove tp prepare a savory pie filling.
Add in the chicken broth and milk. Stir well, making sure there are no flour clumps.
Adding pease, carrots, and cubed chicken to a pot on the stove with milk and chicken broth.
Add in the cubed chicken, veggies, and spices.
Cooking the filling for chicken pot pie in a pot on the stove.
Stir and let simmer for a couple of minutes.
Rolling out pie crust on a kitchen counter.
Roll out the pie crust a little larger than your baking dish.
Pouring chicken pot pie filling into a baking dish.
Pour the filling into a 9x9" greased baking dish.
Topping a baking dish with chicken pot pie filling with a pie crust.
Gently lay the crust on top and crimp the edges to seal.
Brushing an egg wash over the top of a pie crust for a chicken pot pie casserole
Cut a couple of small silts in the top for steam to escape when baking. Gently brush with an egg wash. Bake for 35-40 minutes or until the crust is golden brown and the center is bubbly.

PRO TIP - And if you're short on time, you can use premade rotisserie chicken and a storebought pie crust, transforming it into a quick weeknight meal that's equally comforting! This meal also can be made ahead of time and can be frozen for later so you can enjoy a hearty, satisfying meal when you need it.

Ingredients

Scale
  • 3 Tablespoons Butter
  • 1 Medium Sized Onion - diced
  • 1 Cup Celery - diced
  • 2-3 Garlic Cloves - minced
  • 3 Tablespoons Flour
  • 1 ½ Cups Whole Milk
  • 1 ½ Cups Chicken Broth
  • ¾ Teaspoon Salt
  • ½ Teaspoon Thyme
  • ½ Teaspoon Basil
  • ½ Teaspoon White Pepper
  • ¼ Teaspoon Pepper
  • ⅛ Teaspoon Nutmeg
  • 3 Cups Cooked Chicken Breast (3 large breasts or roughly 2 pounds) - cubed
  • 1 Cup Frozen Peas and Carrots
  • 1 Homemade Pie Crust (or storebought)
  • 1 Egg - for egg wash


Instructions

  1. Preheat the oven to 375 degrees.
  2. Place a large pot on the stove over medium heat. Add in butter, onion, and celery. Saute until the onions are soft, about 5 minutes. Add in the garlic and saute for another 5 minutes, or until everything is soft and fragrant.
  3. Add in flour and mix thoroughly - stir for 2-3 minutes making a thick coating on the vegetables.
  4. Slowly pour in ½ cup of milk and mix, combining the flour and veggie mixture well. Add in the rest of the milk and chicken broth. Stir to make sure no clumps are present.
  5. Turn on medium-low heat. Add in all of the spices, cooked chicken, and frozen veggies. Give it a good stir and let it simmer for 5 minutes.
  6. Pour into a greased 9x9 baking dish. Top with pie crust and crimp around the edge of the baking dish to seal. Cut a couple of small slits in the top for steam to escape and brush gently with an egg wash.
  7. Bake for 35-40 minutes and until the crust is golden brown and the filling is bubbly. Remove and let cool for 10 minutes before serving.

Notes

  • Any kind of cooked chicken can be used for this. Cut-up rotisserie chicken breast, baked chicken, leftover chicken, etc. Whatever kind of white meat chicken you would like to use to make this easy is great!
  • You can use fresh veggies if desired (½ cup diced carrots and ½ cup peas).
  • For the crust - if you use the homemade pie crust recipe, use half (which is 1 pie crust - freeze the other crust, double this recipe, or use it to make a quiche). For a store-bought crust, make sure you get the sheet of pie crust and not the premade shell.
  • Keep leftovers stored in the fridge wrapped tightly for 2-3 days.

Making Ahead

  • The day before: make the filling completely and pour into a greased baking dish. Wrap in plastic wrap and store in the fridge for up to 24 hours. When ready to bake, remove from the fridge, top with the crust, and bake at 375 for 40 minutes or until the filling is hot and bubbly and the crust is slightly golden brown.
  • To freeze: make completely (including crust) and pour into a greased baking dish. Wrap airtight in plastic wrap and then in foil. Write on the top what it is. Place in the freezer for up to 6 months. Bake from frozen (unwrap to remove the plastic wrap then wrap the top in foil) at 375 for 60 minutes (removing the foil the last 30 minutes to brown the crust) or until the center is hot and bubbly and the crust is slightly golden brown.
