Classic Shepherd’s Pie
Ingredients
The Meat Filling:
-
1 lb extra-lean ground lamb (or ground beef if you prefer a traditional Cottage Pie)
-
1 medium yellow onion, finely diced
-
2 large carrots, peeled and diced
-
1 cup frozen peas
-
2 cloves garlic, minced
-
2 tbsp tomato paste
-
1 cup beef broth
-
1 tbsp Worcestershire sauce
-
1 tsp fresh thyme (plus a sprig for garnish)
-
Salt and freshly ground black pepper to taste
-
1 tsp olive oil
The Mashed Topping:
-
1.5 lbs Yukon Gold or Russet potatoes, peeled and cubed (To make this a low-carb, WW-friendly dish, swap half or all of the potatoes for cauliflower florets!)
-
1/4 cup skim milk or unsweetened almond milk
-
2 tbsp light butter or plain Greek yogurt (for extra protein and creaminess)
-
1/4 cup reduced-fat shredded cheddar cheese
-
Salt and pepper to taste
Instructions
-
Boil the Mash: Place the cubed potatoes (and cauliflower, if using) in a large pot and cover with cold, salted water. Bring to a boil and cook until fork-tender, about 15 minutes. Drain completely.
-
Whip the Topping: Mash the drained potatoes with the milk, butter or Greek yogurt, salt, and pepper until completely smooth and fluffy. Set aside.
-
Brown the Meat: Heat the olive oil in a large, oven-safe skillet over medium-high heat. Add the ground meat and diced onions. Cook until the meat is fully browned and the onions are soft. Drain any excess fat from the pan.
-
Build the Flavor: Stir in the garlic, carrots, and tomato paste. Cook for 2 minutes, stirring constantly so the tomato paste deepens in color.
-
Simmer the Filling: Pour in the beef broth and Worcestershire sauce. Add the fresh thyme, salt, and pepper. Bring the mixture to a gentle simmer, reduce the heat, and let it thicken for about 10 minutes. Stir in the frozen peas during the last 2 minutes. (Tip: You can also prep this meat filling in a slow cooker on LOW for 4-5 hours to let the flavors marry before assembling).
-
Assemble the Pie: If your skillet isn’t oven-safe, transfer the thickened meat filling into a 9×9 baking dish. Spoon the mashed topping over the meat and spread it evenly. Drag the tines of a fork across the mash to create textured ridges—these peaks will crisp up beautifully in the oven. Sprinkle the shredded cheese evenly over the top.
-
Bake: Bake at 400°F (200°C) for 25-30 minutes, or until the edges are bubbling and the potato topping is a rich golden brown.
-
Rest and Serve: Let the pie rest for 10-15 minutes before serving so the filling can set. Garnish with a fresh thyme sprig right in the center.
