📝 About This Recipe

A quintessential British classic, this Cottage Pie features succulent ground beef simmered in a deeply savory red wine and thyme gravy, topped with a cloud of buttery, golden-crusted mashed potatoes. Unlike its cousin the Shepherd's Pie which uses lamb, this beef-based version offers a robust, hearty flavor profile that epitomizes soulful comfort food. It is the ultimate family centerpiece, promising a perfect balance of tender vegetables, melt-in-your-mouth meat, and a crispy, fork-raked potato topping.

🥗 Ingredients

The Savory Beef Filling

  • 2 pounds Lean Ground Beef (85/15 blend is ideal for flavor)
  • 2 tablespoons Olive Oil (extra virgin)
  • 1 large Yellow Onion (finely diced)
  • 2 medium Carrots (peeled and cut into small cubes)
  • 2 pieces Celery Stalks (finely sliced)
  • 3 cloves Garlic (minced)
  • 2 tablespoons Tomato Paste (for richness and color)
  • 2 tablespoons Worcestershire Sauce (adds essential umami)
  • 1/2 cup Dry Red Wine (such as Cabernet or Merlot)
  • 1.5 cups Beef Broth (low sodium preferred)
  • 1 tablespoon Fresh Thyme (leaves stripped from stems)
  • 1 cup Frozen Peas (added at the end to keep green)

The Velvet Potato Topping

  • 2.5 pounds Russet or Yukon Gold Potatoes (peeled and chopped into even chunks)
  • 4 tablespoons Unsalted Butter (softened)
  • 1/2 cup Milk or Heavy Cream (warmed)
  • 1/2 cup Sharp Cheddar Cheese (shredded (optional for crust))
  • 1 piece Egg Yolk (for a rich, golden finish)
  • to taste Salt and Black Pepper (freshly cracked)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 400°F (200°C). Place the chopped potatoes in a large pot of salted cold water. Bring to a boil, then reduce heat and simmer for 15-20 minutes until fork-tender.

  2. 2

    While potatoes boil, heat olive oil in a large oven-proof skillet or Dutch oven over medium-high heat. Add the ground beef, breaking it up with a wooden spoon, and cook until browned. Drain excess fat if necessary.

  3. 3

    Add the diced onions, carrots, and celery to the beef. Sauté for 6-8 minutes until the vegetables have softened and the onions are translucent.

  4. 4

    Stir in the minced garlic and tomato paste. Cook for 2 minutes, stirring constantly, until the paste turns a deep brick red and smells fragrant.

  5. 5

    Pour in the red wine to deglaze the pan, scraping up any browned bits (fond) from the bottom. Let the wine reduce by half.

  6. 6

    Add the beef broth, Worcestershire sauce, and fresh thyme. Bring to a gentle simmer, then reduce heat to low and let it bubble for 15 minutes until the sauce has thickened into a rich gravy.

  7. 7

    Stir in the frozen peas during the last minute of simmering. Taste and season generously with salt and pepper. Remove from heat.

  8. 8

    Drain the cooked potatoes and return them to the hot pot for 1 minute to steam dry. Mash thoroughly with a potato masher or ricer until no lumps remain.

  9. 9

    Mix in the butter, warm milk/cream, and the egg yolk. Stir until the potatoes are fluffy and smooth. Season with salt and pepper.

  10. 10

    If your skillet isn't oven-safe, transfer the beef mixture to a 9x13 inch baking dish. Spread the mashed potatoes evenly over the top.

  11. 11

    Use a fork to create decorative ridges or 'peaks' across the surface of the potatoes; these will catch the heat and become crispy. Sprinkle with cheddar cheese if using.

  12. 12

    Place the dish on a baking sheet (to catch drips) and bake for 25-30 minutes, or until the gravy is bubbling up the sides and the potato topping is beautifully golden brown.

  13. 13

    Remove from the oven and let it rest for 5-10 minutes before serving. This allows the layers to set so you get a perfect slice.

💡 Chef's Tips

For the smoothest topping, use a potato ricer instead of a masher to eliminate all lumps. Don't skip the 'steaming dry' step for the potatoes; removing excess moisture ensures they don't sink into the meat. If the gravy looks too thin before topping, mix 1 tsp of cornstarch with water and stir it in while simmering. For an extra flavor punch, add a teaspoon of Dijon mustard to the mashed potatoes. You can prepare the filling a day in advance; cold filling makes it even easier to spread the warm potatoes on top.

🍽️ Serving Suggestions

Serve with a side of buttered leeks or steamed seasonal greens like kale or savoy cabbage. A crisp green salad with a sharp vinaigrette helps cut through the richness of the beef. Pair with a glass of the same red wine used in the recipe, or a cold British Ale. Offer a bottle of extra Worcestershire sauce at the table for those who love a spicy, tangy kick. Freshly baked crusty bread is perfect for mopping up any leftover gravy.
