Classic Homemade Chicken Pot Pie is the steady dinner hero you need tonight. Using rotisserie chicken cuts the prep work in half without losing that scratch-made taste. We are talking tender vegetables, a thick sauce that actually coats the spoon, and a top crust that stays crisp. It is a reliable meal that feeds the whole table and makes the kitchen smell amazing. Perfect for a Sunday supper or a busy weeknight.
Preheat oven to 400°F (205°C). Place bottom crust in a 9-inch pie dish (if using) and refrigerate.
Melt butter in a large pot over medium heat. Add onion, celery, carrots. Cook 6–8 minutes. Add garlic and cook 30 seconds.
Stir in flour and cook 1–2 minutes. Slowly whisk in broth, then milk. Simmer 3–5 minutes until thickened.
Add chicken and potatoes. Simmer 10–12 minutes until potatoes are tender. Stir in peas during the last 2 minutes. Season with salt, pepper, thyme, parsley, and poultry seasoning if using. Turn off heat and cool 10–15 minutes.
Pour filling into pie dish. Top with second crust. Trim and crimp edges. Cut slits on top.
Brush with egg wash.
Bake 35–45 minutes until golden and bubbling. If browning too fast, tent with foil.
Rest 15 minutes before slicing.
Notes
For top-crust only, pour filling into a greased baking dish and cover with one crust.For crispier reheating, warm slices in the oven at 350°F for 15–20 minutes.Freeze unbaked for best texture and bake from frozen 60–75 minutes at 400°F.
