This beef pot pie is simple and easy to make. A savory meaty filling packed with veggies and flavor and topped with a golden buttery crust, what else could you want?
Cook the filling. Heat the olive oil in a cast iron skillet over medium heat. Add the ground beef, onion, and celery and cook until the beef is browned and the onion is soft. Drain excess grease if needed.
Season the mixture. Stir in the salt, black pepper, Italian seasoning, dried thyme, and Worcestershire sauce until well combined.
Add vegetables and liquids. Stir in the frozen mixed vegetables, 1 ½ cups of the chicken broth, and the cream of mushroom soup.
Thicken the filling. In a small bowl, whisk the remaining ½ cup chicken broth with the cornstarch until smooth. Stir the slurry into the skillet. Bring the mixture to a boil and cook for 5 minutes, stirring constantly, then remove from the heat.
Preheat the oven. Preheat the oven to 350°F.
Top with crust. Place the pie crust over the skillet, pressing the edges into the pan. Cut a small vent in the center of the crust.
Add egg wash. Whisk together the egg and water and brush over the top of the crust.
Bake. Bake for 30 minutes, until the crust is golden brown.
Rest and serve. Let the pot pie rest for about 10 minutes to thicken before serving.
Notes
Extra hearty option. Add drained and rinsed canned potatoes just before simmering for a more filling pie.
Crust handling. Work quickly with the pie crust, as it softens as it warms. A butter knife helps shape the edges.
Storage. Transfer leftovers to an airtight container and refrigerate for up to 3 days. Avoid storing cast iron pans in the refrigerator.
