Method
Step-by-Step
- Heat the oven to 400°F. Melt the butter in a 10- or 12-inch oven-safe cast-iron skillet over medium heat, then cook the onion, carrots, and celery for 5–7 minutes, until the vegetables begin to soften.
- Add the minced garlic and cook for about 30 seconds. Sprinkle in the flour and stir continuously for 1–2 minutes so the raw flour cooks without browning too much.
- Gradually whisk in the chicken broth, followed by the milk or cream. Simmer for 3–5 minutes, stirring often, until the sauce thickens enough to coat a spoon.
- Stir in the cooked chicken, frozen peas, thyme, kosher salt, and black pepper. Remove the skillet from the heat once the mixture is hot and fairly thick.
- Lay the pie crust or puff pastry over the skillet, trimming or folding the edges as needed. Cut several vents in the top to let steam escape.
- Beat the egg with the water, then brush the mixture evenly over the pastry. Place the skillet on a rimmed baking sheet to catch any bubbling filling or drips.
- Bake for 25–35 minutes, until the pastry is deeply golden and the filling is bubbling. If the crust browns too quickly, loosely cover it with foil.
- Let the pot pie stand for about 10 minutes before serving. This resting time allows the sauce to thicken so each scoop holds together better.
Notes
For raw chicken, poach or roast about 1 1/4 pounds boneless chicken to produce approximately 3 cups cooked meat, and confirm that the chicken reaches 165°F internally. Keep puff pastry cold until it goes into the oven for especially crisp results. Store leftovers refrigerated and reheat gently until hot.
