Ingredients
- For the Filling:
- 1 lb ground beef
- 1 cup mushrooms, finely chopped
- ½ onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon dried thyme
- ¼ cup parsley, chopped (optional)
- For the Sauce:
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 cup beef broth
- 1 tablespoon heavy cream
- 1 teaspoon soy sauce
- For the Casserole:
- 1 package (14 oz) puff pastry, thawed
- 1 egg, beaten (for egg wash)
Directions
- Preheat the Oven: Begin by preheating your oven to 400°F (200°C). This ensures that your casserole will cook evenly and the pastry will puff up beautifully.
- Cook the Ground Beef Mixture: In a large skillet over medium heat, add the ground beef and cook until browned. Drain any excess fat.
- Add Vegetables: Stir in the chopped mushrooms, onion, and garlic. Sauté for about 5-7 minutes, until the vegetables are softened.
- Season the Mixture: Add the Worcestershire sauce, Dijon mustard, salt, pepper, thyme, and parsley. Mix well and cook for another 2-3 minutes to let the flavors meld. Remove from heat and let cool slightly.
- Prepare the Sauce: In a separate saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes until it forms a paste. Gradually add the beef broth while whisking continuously to avoid lumps.
- Thicken the Sauce: Bring the mixture to a simmer and let it thicken for about 3-5 minutes. Stir in the heavy cream and soy sauce, then remove from heat.
- Combine Mixtures: Pour the sauce over the beef and vegetable mixture, stirring to coat evenly.
- Prepare the Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry sheet. Cut it into rectangles that are large enough to hold the filling.
- Fill the Pastry: Place a scoop of the beef filling on each rectangle of pastry.
- Seal the Wellingtons: Fold the pastry over the filling to create a pocket. Use a fork to crimp the edges, sealing in the delicious goodness.
- Egg Wash: Place the filled pastries onto a baking sheet lined with parchment paper. Brush the tops with the beaten egg to give them a golden brown color while baking.
- Bake: Bake in the preheated oven for 20-25 minutes, or until the pastry is puffed and golden brown.
- Cool and Serve: Once baked, let the Ground Beef Wellingtons cool for a few minutes before serving. They are best enjoyed warm and can be paired with a fresh salad or steamed vegetables for a complete meal.

Tips for the Perfect Ground Beef Wellingtons
- Don’t Overfill: Make sure not to overfill your pastry, as this can cause them to burst while baking.
- Make Ahead: You can prepare the beef filling in advance and assemble the Wellingtons just before baking for a stress-free dinner.
- Experiment with Flavors: Feel free to add other ingredients like spinach, cheese, or different herbs to customize the filling to your preference.
- Serve with Style: These Wellingtons are excellent with a side of mashed potatoes or a rich gravy.
