Key reasons to love this recipe:

  • Easy to prepare: Uses leftovers and pantry staples, saving time and reducing food waste.
  • Customizable: Swap in your favorite vegetables or add herbs and spices you love.

  • Perfect for any season: Cozy and warming in the winter, yet still great year-round.
  • Make-ahead option: Assemble in advance and bake when ready.

Ingredients

  • 2 cups leftover roast beef, diced or shredded
  • 2 cups mixed vegetables (carrots, peas, corn, green beans, or your choice)
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups beef broth
  • 1/2 cup milk or cream
  • 1 teaspoon Worcestershire sauce (optional, for depth of flavor)
  • Salt and freshly ground black pepper, to taste
  • 1 teaspoon dried thyme or fresh if available
  • 1 sheet ready-made puff pastry or pie crust
  • 1 egg, beaten (for egg wash)

Equipment

  • Large skillet or saucepan
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Pie dish or oven-safe baking dish (8-inch or similar)
  • Rolling pin (if needed for pastry)
  • Baking sheet (optional, to place under pie while baking)
  • Pastry brush
  • Oven

Instructions

  1. Prepare the filling: Heat the butter in a large skillet over medium heat. Add the chopped onion and cook until soft and translucent, about 5 minutes.
  2. Add garlic and flour: Stir in the minced garlic and cook for 1 minute. Sprinkle the flour over the onions and garlic, stirring constantly to form a roux. Cook for 2-3 minutes until it turns a light golden color.
  3. Create the gravy: Gradually whisk in the beef broth and milk, ensuring no lumps form. Continue to cook, stirring frequently, until the sauce thickens and coats the back of a spoon.
  4. Season the filling: Add Worcestershire sauce, thyme, salt, and pepper to taste. Stir well to combine.
  5. Add beef and vegetables: Fold in the diced leftover roast beef and mixed vegetables, mixing until everything is evenly coated with the gravy. Remove from heat.
  6. Prepare the pastry: Preheat your oven to 400°F (200°C). Roll out the puff pastry if needed to fit your pie dish. Transfer the beef and vegetable filling into the dish.
  7. Assemble the pot pie: Lay the pastry sheet over the filling, trimming any excess dough. Press the edges down to seal and crimp decoratively if desired. Cut a few small slits in the pastry to allow steam to escape.
  8. Brush with egg wash: Using a pastry brush, gently coat the pastry with the beaten egg to achieve a golden, glossy finish.
  9. Bake: Place the pot pie on a baking sheet and bake in the preheated oven for 25-30 minutes, or until the pastry is puffed and golden brown.
  10. Rest and serve: Let the pie rest for 5-10 minutes before serving to allow the filling to set slightly.

Tips & Variations

Tip: If you don’t have puff pastry, a homemade pie crust or biscuit topping works wonderfully as well.

Variation: For added flavor, sauté mushrooms with the onions or add a splash of red wine to the gravy.

Make it vegetarian: Swap the roast beef for mushrooms or lentils and use vegetable broth instead of beef broth. Check out our A to Z Vegetarian Recipes for Every Meal and Occasion for more inspiration.

Storage: Leftover pot pie can be refrigerated for up to 3 days or frozen for up to 2 months.
