(Jenni) Turkey Pot Pie

I love the show on PBS called EVERYDAY FOOD. I had so much turkey left over after Thanksgiving so I made this easy yummy pot pie. The carrots and celery were left over from the veggie tray. WIN WIN!!! You can also use chicken. Thayne loved it!
Here is a link to watch everyday food's chicken pot pie. Check it out!

4 tablespoons unsalted butter

1 medium onion, cut into medium dice

1 large carrot, cut into medium dice

1/2 cup all-purpose flour, plus more for work surface

coarse salt and ground pepper

4 cups low-sodium chicken broth

3 cups cooked chicken, cut into (or turkey)

1-inch pieces (1 pound total)

1 cup frozen peas

1 1/2 teaspoons chopped fresh thyme leaves

1 sheet frozen puff pastry, thawed

1 large egg yolk

.*I used a can of biscuits instead of the pastry.

1. In a medium saucepan, melt butter over medium. Add onion and carrot and cook until onion softens, about 6 minutes. Add flour and 1/2 teaspoon salt; cook, stirring frequently, until mixture is pale golden, has a slightly nutty aroma, and is the texture of cooked oatmeal, about 5 minutes.
2. Whisking constantly, add broth. Bring to a boil, stirring frequently, until mixture thickens, about 8 minutes. Reduce to a simmer and cook 10 minutes. Stir in chicken, peas, and thyme; season with salt and pepper. Divide mixture among four 12-ounce baking dishes; refrigerate until room temperature, about 20 minutes.
3. Preheat oven to 375 degrees. On a lightly floured work surface, roll pastry to an 1/8-inch thickness. Cut into 4 equal squares, 1 inch larger than dishes; with the tip of a sharp knife, cut vents into pastry. In a small bowl, lightly beat egg yolk with 1 teaspoon water; top potpies with pastry and brush with egg wash. Refrigerate 15 minutes. Bake until pastry is deep golden and juices are bubbling, about 35 minutes.
