Classic Shepherd’s Pie is the ultimate comfort food, featuring a rich and savory layer of ground lamb simmered with vegetables and herbs. This traditional Irish dish is defined by its crowning glory: a thick, velvety layer of mashed potatoes that is baked until golden brown and slightly crisp on top.

Perfect for chilly evenings or family gatherings, this hearty casserole brings together simple, wholesome ingredients to create a timeless favorite that feels like a warm hug in a bowl.

Key Ingredients

• 1.5 pounds ground lamb

• Salt and pepper to taste

Step-by-Step Instructions

1. Place the cubed potatoes in a large pot of salted water, bring to a boil, and cook for 15-20 minutes until tender.
2. While potatoes cook, brown the ground lamb in a large skillet over medium-high heat until fully cooked, draining any excess fat.
3. Add the diced onion and minced garlic to the skillet with the lamb, sautéing for 3-5 minutes until the onions are translucent.
4. Stir in the tomato paste, dried thyme, and frozen peas and carrots, then pour in the beef broth and simmer for 5-10 minutes until the sauce has thickened.
5. Drain the cooked potatoes and mash them with butter and milk until smooth, seasoning with salt and pepper as needed.
6. Preheat your oven to 400°F (200°C).
7. Transfer the lamb mixture into a 9×9 inch baking dish and spread the mashed potatoes evenly over the top.
8. Sprinkle with shredded cheddar cheese and bake for 20 minutes, or until the top is golden brown and the edges are bubbling.
