Full Recipe:

Ingredients:

For the filling:

• 1 kg beef mince
• 1 onion, finely chopped
• 2 tablespoons olive oil
• 2 garlic cloves, crushed
• 2 carrots, grated
• 150 ml red wine
• 2 tablespoons Worcestershire sauce
• 1 tablespoon tomato paste
• 250 ml beef stock
• 400 g canned lentils, drained and rinsed
• 400 g chopped tomatoes
• 1/2 cup spinach, chopped
• 2 tablespoons fresh parsley, finely chopped
• 2 teaspoons fresh thyme
• Salt and freshly ground black pepper, to taste

For the topping:

• 1.2 kg kūmara (sweet potatoes), peeled and chopped
• 200 ml milk
• 25 g butter
• 1/2 cup grated cheddar cheese

Directions:

1. Prepare the filling:

   • Heat 1 tablespoon of olive oil in a large saucepan over medium-high heat. Add the beef mince and cook until browned, breaking it up with a spoon. Remove and set aside.
   • In the same pan, add the remaining olive oil. Sauté the onion and garlic over low heat for about 5 minutes until softened.
   • Increase the heat to medium, add the grated carrots, and cook for another 5 minutes.
   • Return the browned mince to the pan. Stir in Worcestershire sauce, chopped tomatoes, tomato paste, beef stock, red wine, and lentils. Season with salt and pepper.
   • Reduce heat to low, cover, and let the mixture simmer for 30 minutes, stirring occasionally, until the sauce thickens.
   • Five minutes before the end of cooking, add chopped spinach, parsley, and thyme. Stir well to combine.

2. Prepare the topping:

   • While the filling simmers, place the kūmara pieces in a large pot of salted water. Bring to a boil and cook until tender, about 15-20 minutes.
   • Drain the kūmara and return to the pot. Add milk and butter, then mash until smooth. Season with salt and pepper to taste.

3. Assemble and bake:

   • Preheat the oven to 200°C (400°F).
   • Transfer the beef and lentil mixture into a large baking dish, spreading it evenly.
   • Spoon the mashed kūmara over the filling, smoothing the top. Sprinkle with grated cheddar cheese.
   • Bake in the preheated oven for 20-25 minutes, until the top is golden and the filling is bubbling.
   • Let the pie rest for a few minutes before serving.

History and Origin of Cottage Pie

Cottage Pie has been a staple of British and Irish cuisine for centuries. The dish dates back to the 18th century when it was a practical way for families to use leftover meat. Traditionally, the pie was made with minced or shredded beef, cooked with vegetables and topped with mashed potatoes. The term “Cottage Pie” was first used in the 1790s and was named after the modest cottages of rural workers who relied on inexpensive ingredients to create hearty meals.

Over time, variations of the dish emerged, incorporating different proteins and vegetables. In this modern version, lentils are added to provide a boost of plant-based protein and fiber, making it a nutritious twist on the classic recipe. The use of kūmara (sweet potato) mash instead of traditional potatoes brings a subtle sweetness and extra vitamins to the dish.

Why This Recipe Stands Out

1. Protein-Packed – The combination of beef and lentils provides a double source of protein, making it filling and balanced.
2. Rich in Nutrients – Lentils add fiber, iron, and folate, while kūmara is packed with vitamin A, potassium, and antioxidants.
3. Flavorful and Comforting – The slow-simmered beef mixture, infused with red wine and Worcestershire sauce, enhances the dish with deep, savory flavors.
4. Perfect for Meal Prep – This dish can be made ahead of time, stored in the fridge, and reheated when needed.
5. Gluten-Free Option – The recipe is naturally gluten-free if Worcestershire sauce is replaced with a gluten-free alternative.

Cooking Tips and Variations

• Enhancing the Flavor

  • Brown the beef mince properly to develop rich, caramelized flavors. Avoid overcrowding the pan.
  • A dash of balsamic vinegar or a spoonful of marmite can add umami depth to the beef mixture.
  • Adding a teaspoon of smoked paprika gives the dish a warm, smoky taste.

• Vegetarian and Vegan Adaptations

  • Replace the beef with extra lentils, mushrooms, or a plant-based meat substitute for a vegetarian version.
  • Swap butter and cheese with vegan alternatives and use a plant-based milk for the mash.

• Make it Dairy-Free

  • Use olive oil instead of butter in the mash.
  • Replace cheese with nutritional yeast for a cheesy flavor without dairy.

• Other Topping Ideas

  • Instead of kūmara mash, try mashed cauliflower for a low-carb version.
  • A mix of white and sweet potatoes balances sweetness with a traditional creamy texture.

Serving Suggestions

• Serve hot with a side of steamed green beans or roasted Brussels sprouts.
• Pair with a light salad featuring a tangy vinaigrette to balance the richness.
• For extra indulgence, drizzle with a homemade gravy before serving.

Storage and Reheating Instructions

• Refrigeration: Store in an airtight container for up to 3 days.
• Freezing: Assemble the pie but don’t bake it. Cover tightly and freeze for up to 3 months.
  • When ready to eat, bake directly from frozen at 180°C (350°F) for 50-60 minutes.
• Reheating:
  • Oven: Bake at 180°C (350°F) for 20 minutes until heated through.
  • Microwave: Heat individual portions in a microwave-safe dish for 2-3 minutes.

Cooking Tips and Tricks

How to Enhance the Flavor

• Brown the meat properly – Cooking the mince on high heat caramelizes the natural sugars, intensifying the flavor.
• Deglaze with red wine – This helps extract extra umami from the pan, making the sauce richer.
• Slow simmer the filling – Letting the sauce reduce for at least 30 minutes ensures a thicker, more flavorful base.

Ingredient Substitutions

• Make it Vegetarian: Swap beef for mushrooms or plant-based mince, and use vegetable stock instead of beef stock.
• Gluten-Free Option: Ensure Worcestershire sauce is gluten-free, or replace it with tamari or coconut aminos.
• Dairy-Free Version: Use plant-based butter and milk for the kūmara mash.

Texture and Topping Variations

• For a crispier top: Sprinkle breadcrumbs or crushed nuts before baking.
• For extra creaminess: Add a splash of coconut milk or Greek yogurt to the mash.
• For a traditional touch: Mix half regular potatoes and half kūmara for a balanced flavor.

Serving Suggestions

• Serve hot with a side of steamed greens, roasted Brussels sprouts, or garlic butter asparagus.
• Pair with a fresh garden salad dressed with balsamic vinaigrette.
• Enjoy with a glass of red wine for an elegant dining experience.

Storage and Reheating Tips

• Refrigerate: Store leftovers in an airtight container for up to 3 days.
• Freeze: Assemble but do not bake; freeze for up to 3 months. Bake directly from frozen at 180°C (350°F) for 50-60 minutes.
• Reheat: Warm individual portions in the microwave (2-3 minutes) or oven (15-20 minutes at 180°C/350°F).
