Creating the perfect Beef Pot Pie can be simple when you follow these clear steps:

1. Preheat the Oven: Set your oven to 425°F (220°C).
2. Brown the Beef: In a large pot, heat the olive oil over medium heat. Add the beef stew meat and cook until browned on all sides. This step locks in flavors.
3. Sauté Vegetables: Add the diced onion, carrots, and celery to the pot. Cook for about 5-7 minutes until the vegetables begin to soften. Stir in the minced garlic and cook for another minute.
4. Make the Gravy: Pour in the beef broth and Worcestershire sauce. Add thyme, salt, and pepper. Bring this mixture to a simmer. It should bubble slightly; reduce heat and cover for about 20 minutes.
5. Add Potatoes and Peas: Stir in the diced potatoes and frozen peas along with any additional seasonings to adjust taste. If you prefer a thicker gravy, mix cornstarch with water in a small bowl and stir it into the pot. Cook for another 5-10 minutes until the potatoes are tender.
6. Prepare the Pie Crust: Roll out your pie crust on a flat surface if using homemade dough. If using store-bought, unroll it directly onto your pie dish.
7. Fill the Pie: Pour the beef and vegetable mixture into the pie crust, spreading it out evenly.
8. Top with Crust: Place the second pie crust over the filling. Cut slits in the top crust to allow steam to escape.
9. Apply Egg Wash: Brush the top crust with beaten egg for a golden color when baked.
10. Bake: Place the pot pie in the preheated oven and bake for about 30-35 minutes or until the crust is golden brown.
11. Cool Before Serving: Once baked, let it cool for around 15 minutes to allow the filling to set before slicing.

These steps will lead you to an incredible Beef Pot Pie that not only fills the tummy but warms the soul.
