Country Chicken and Mushroom Pot Pie

Step 1
Combine 1 cup boiling water and chicken bouillon in a liquid measure; set aside to dissolve.

Step 2
Meanwhile, melt 1 tablespoon butter in a pot over medium heat. Add onions and saute until translucent, about 5 minutes. Increase heat to medium-high and add mushrooms; fry for about 3 minutes. Remove onion-mushroom mixture from the pot.

Step 3
Add remaining butter to the pot with chicken pieces. Stir chicken and splash Worcestershire sauce over top. Cook, stirring continuously, until chicken is seared on all sides but not cooked through, about 3 minutes. Stir in onion-mushroom mixture, bouillon, and pepper.

Step 4
Add milk and 1/4 cup water; boil for 20 minutes. Add frozen vegetables and boil for 10 more minutes.

Step 5
Preheat the oven to 400 degrees F (200 degrees C). Grease an 8-inch oven-proof dish and lay down bottom crust in it. Set top crust aside.

Step 6
After filling has boiled for 10 minutes, use a large ladle to scoop out approximately 1 cup sauce from the mixture and pour into a cup. Add cornstarch to the cup and stir until all lumps have dissolved. Add cornstarch mixture back to the pot; cook and stir until filling has thickened to your liking.

Step 7
Bake bottom crust in the preheated oven for approximately 5 minutes. Remove from the oven, add filling, and cover with the top crust, making sure the edges are sealed. Make cute decorations with pastry cut-offs and use a knife to make several small slits in the top to allow steam to escape. Lightly paint egg yolk over the top crust.

Step 8
Bake until golden brown, 15 to 20 minutes. Ovens vary so baking time may vary-keep an eye on it.
