Creating these Shepherd’s Pie Phyllo Cups is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook the Meat: In a large skillet over medium heat, cook the ground lamb or beef until browned. Drain excess fat if necessary.
3. Add Vegetables: Add the chopped onion, garlic, and diced carrots to the skillet. Sauté until the vegetables are tender.
4. Season: Stir in the peas, tomato paste, Worcestershire sauce, thyme, rosemary, salt, and pepper. Pour in the beef broth and simmer for about 10 minutes, allowing the mixture to thicken slightly.
5. Prepare Phyllo Cups: While the filling is simmering, prepare the phyllo pastry. Lay one sheet of phyllo on a clean surface and brush it lightly with melted butter. Top with another sheet and repeat the process for a total of 4 sheets.
6. Cut and Shape: Using a sharp knife, cut the phyllo stack into squares. Gently press each square into a muffin tin, allowing the edges to hang over the sides.
7. Fill Cups: Spoon the meat and vegetable mixture into each phyllo cup, filling them about three-quarters full.
8. Top with Mashed Potatoes: Pipe or spoon the mashed potatoes on top of the filling, smoothing it out as needed.
9. Bake: Bake in the preheated oven for 25-30 minutes or until the phyllo is golden brown and crispy.
10. Add Cheese (Optional): If desired, sprinkle shredded cheddar cheese on top and return to the oven for an additional 5 minutes until melted.
11. Cool: Remove from the oven and allow the cups to cool for a few minutes before serving.
