Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Heat 2 tbsp olive oil in a heavy skillet over medium-high heat. Add 1 lb diced beef chuck seasoned with 1 tsp salt and 1/2 tsp black pepper. Brown beef for 5-7 minutes until seared on all sides, then remove and set aside.
  2. Step 2: In the same skillet, add 1 large diced yellow onion and sauté for 5 minutes until softened. Add 2 minced garlic cloves and 8 oz sliced button mushrooms and cook for another 5 minutes until mushrooms release moisture and start to brown.
  3. Step 3: Return beef to skillet, sprinkle 2 tbsp all-purpose flour over the mixture and stir for 1 minute to coat. Slowly pour in 1 cup beef broth and 2 tbsp Worcestershire sauce while stirring. Add 1 tsp fresh thyme leaves. Reduce heat to low and simmer for 30 minutes until sauce thickens.
  4. Step 4: Transfer beef mixture to a 9-inch pie dish. Roll out 2 sheets of frozen puff pastry to cover the dish. Place pastry over filling, trim edges, and press to seal. Brush 1 beaten egg over pastry for gloss.
  5. Step 5: Bake in preheated oven for 35-40 minutes until pastry is puffed and golden brown. Let rest for 10 minutes before serving.
