For the Mashed Potato Topping:

• 4 large potatoes, peeled and chopped
• 1/4 cup milk (or more as needed)
• 2 tablespoons butter
• Salt and black pepper to taste
• 1/4 cup shredded cheddar cheese (optional, for topping)

Cooking Directions

Step 1: Prepare the Mashed Potatoes
Boil the peeled potatoes in salted water for 15–20 minutes until tender. Drain, then mash with milk, butter, salt, and pepper until smooth and creamy. Set aside.

Step 2: Cook the Beef Filling
Heat olive oil or butter in a large skillet over medium heat. Add onions and sauté for 3–4 minutes until softened. Add garlic and cook for 1 minute.

Step 3: Brown the Ground Beef
Add the ground beef to the skillet. Cook until browned, breaking it up with a spoon. Drain any excess fat if needed.

Step 4: Add Vegetables and Flavorings
Stir in carrots, peas, and corn. Add tomato paste, beef broth, Worcestershire sauce, thyme, rosemary, salt, and pepper. Simmer for 10–15 minutes until the vegetables are tender and the sauce thickens slightly.

Step 5: Assemble the Cottage Pie
Preheat the oven to 400°F (200°C). Transfer the beef mixture to a greased baking dish. Spread the mashed potatoes evenly over the top. Optionally, sprinkle shredded cheddar cheese on top.

Step 6: Bake
Bake in the preheated oven for 20–25 minutes, until the top is golden and slightly crisp.

Step 7: Serve
Let the pie rest for 5 minutes before serving to allow the layers to set.

Recipe Tips

• Potato Texture: For extra creamy potatoes, add a splash of cream or use a potato ricer.

• Make Ahead: Prepare the beef filling a day in advance, top with mashed potatoes, and bake when ready.

Variations

• Shepherd’s Pie Version: Use ground lamb instead of beef for a traditional Shepherd’s Pie.
• Cheesy Topping: Mix Parmesan or Gruyere into the mashed potatoes for a richer flavor.
• Vegetable Boost: Add mushrooms, celery, or zucchini to the filling for extra nutrition.
• Low-Carb Option: Substitute mashed cauliflower for the potato topping.
