Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F (160°C). Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add 1 lb diced beef chuck and brown evenly on all sides, about 5-7 minutes. Remove and set aside.
  2. Step 2: In the same skillet, add 1 diced medium onion, 1 diced medium carrot, and 3 minced garlic cloves. Sauté for 5 minutes until softened and fragrant.
  3. Step 3: Stir in 8 oz chopped button mushrooms and cook for another 4 minutes until mushrooms release moisture.
  4. Step 4: Sprinkle 3 tbsp all-purpose flour over the vegetables and stir for 1 minute to cook the flour.
  5. Step 5: Slowly add 1 1/2 cups beef stock while stirring, then add 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, 1 tsp fresh thyme leaves, 1 1/2 tsp salt, and 1 tsp black pepper. Return the browned beef to the skillet and mix well.
  6. Step 6: Cover the skillet and transfer to the preheated oven. Bake for 2 hours until beef is tender and the sauce thickens.
  7. Step 7: Remove skillet from oven and increase oven temperature to 400°F (200°C). Lay 2 sheets of puff pastry over the filling, trimming edges and pressing lightly to seal.
  8. Step 8: Brush 1 beaten large egg over the pastry and bake uncovered for 20-25 minutes until puffed and golden brown.
  9. Step 9: Let the pie rest for 10 minutes before serving warm.
