Ingredients
- 1.5 lbs beef chuck, diced
- 2 tbsp olive oil
- 1 large yellow onion, diced
- 3 garlic cloves, minced
- 8 oz button mushrooms, sliced
- 3 tbsp all-purpose flour
- 2 cups beef broth
- 1 tbsp Worcestershire sauce
- 1 tsp fresh thyme leaves
- 1 tsp salt
- 1/2 tsp black pepper
- 2 sheets, thawed frozen puff pastry sheets
- 1 for egg wash egg, beaten
Instructions
- Step 1: Heat 2 tbsp olive oil in a large heavy-bottomed pot over medium-high heat. Add 1.5 lbs diced beef chuck and brown on all sides for 6-8 minutes. Remove beef and set aside.
- Step 2: In the same pot, add 1 large diced yellow onion and cook for 4 minutes until softened. Stir in 3 minced garlic cloves and 8 oz sliced button mushrooms; sauté for 5 minutes until mushrooms release moisture and start to brown.
- Step 3: Sprinkle 3 tbsp all-purpose flour over the vegetables, stir constantly for 2 minutes to cook the flour and create a roux.
- Step 4: Gradually pour in 2 cups beef broth, stirring to prevent lumps. Add the browned beef back to the pot along with 1 tbsp Worcestershire sauce, 1 tsp fresh thyme leaves, 1 tsp salt, and 1/2 tsp black pepper. Bring to a simmer, cover, and reduce heat to low; cook gently for 2 hours until beef is tender and gravy thickens.
- Step 5: Preheat oven to 400°F. Transfer the beef and mushroom mixture to a 9-inch pie dish. Roll out 2 thawed puff pastry sheets and cover the filling, trimming excess pastry and sealing edges with a fork.
- Step 6: Brush the pastry top with 1 beaten egg for a golden finish. Cut a few small slits in the pastry to vent steam. Bake for 25-30 minutes until pastry is puffed and deep golden brown.
- Step 7: Let the pie rest for 10 minutes before serving to allow the filling to set.
