Creating Classic Shepherd’s Pie is straightforward if you follow these simple steps:

1. Preheat your oven to 400°F (200°C).
2. Cook the Potatoes: In a large pot, bring salted water to a boil. Add the peeled and cubed potatoes, and cook until tender, about 15-20 minutes. Drain and set aside.
3. Prepare the Meat Filling: In a large skillet, cook the ground lamb or beef over medium heat until browned, breaking it apart with a spatula.
4. Add Vegetables: Add the chopped onion, diced carrots, and minced garlic to the meat. Sauté until the vegetables soften, about 5-7 minutes.
5. Season the Filling: Stir in the tomato paste, Worcestershire sauce, beef broth, and frozen peas. Add thyme, paprika, salt, and pepper to your taste. Let simmer for about 10 minutes until thickened.
6. Make the Mashed Potatoes: While the meat simmers, mash the potatoes with butter and milk until smooth. Season with salt and pepper as needed.
7. Assemble the Pie: Spread the meat mixture evenly in a baking dish. Top with the mashed potatoes, smoothing it out into an even layer.
8. Bake: Bake in the preheated oven for 20-25 minutes, or until the top is lightly golden.
9. Cool Slightly: Allow to cool for a few minutes before serving, which helps the layers set.

These steps will lead you to a mouthwatering Classic Shepherd’s Pie that is sure to become a favorite in your household!
