A comforting mushroom and leek chicken pot pie recipe for early spring. This recipe makes full use of chicken thighs’ rich flavors, first by cooking the vegetables in rendered chicken fat, and then by gently poaching the thighs and making a flavorful chicken broth for the filling.
This recipe can be made with a sheet of store bought puff pastry dough (I prefer the all-butter varieties) or homemade pie dough.
Set the seared chicken in the broth, if possible, try to perch the chicken on top of the vegetables so it’s not fully submerged. Partially cover the pot and simmer until chicken starts to pull off the bone, about 20 minutes.
Set the cast iron skillet over medium/medium-high heat (so that pan is hot, but not smoking). Add 1 tablespoon chicken fat and half the mushrooms. Sprinkle with sea salt and pepper. Cook, stirring occasionally, until mushrooms have crisp edges. Remove mushrooms to a dish. Repeat for the second batch. Add another tablespoon chicken fat to the skillet (use olive oil if you run out), add the leeks, sprinkle with sea salt and pepper, and sauté until they’re tender. Fold in the mushrooms and potatoes. Add the flour and stir until flour darkens and covers all the vegetables. Turn heat to medium-low.
Strain the broth and set the chicken thighs aside to cool. When cool enough to handle, pull meat off of chicken bones and rough chop.
Add 2 - 3 cups broth, ½ cup at a time, to the skillet, stirring often and giving the mixture time to thicken between additions. Finally, fold in the chicken. Taste and add sea salt and pepper to taste.
Bake 20 minutes, or until crust is golden, then turn heat down to 350 degrees F, and bake pot pie 30 - 35 minutes, or until crust is a deep golden hue and the filling is bubbling vigorously.
