Grilled Shepherd’s Pie Stuffed Peppers: A British Classic on the Arteflame

There is something undeniably comforting about a classic British Shepherd’s Pie, with its savory minced lamb and fluffy mashed potato topping. But when you take those familiar flavors, stuff them into vibrant bell peppers, and fire up your Arteflame grill, you elevate a humble family dinner into a gourmet outdoor experience. The slight char on the peppers adds a smoky depth that an oven simply cannot replicate, creating a delightful contrast with the creamy potatoes and rich meat filling. This recipe brings the best of both worlds: the hearty warmth of traditional pub food and the dynamic, open-fire cooking style that makes every meal memorable. It is the perfect dish for a chilly autumn evening or a robust weekend lunch, allowing you to prepare the entire meal—from sautéing the filling to baking the peppers—right on the cooktop.

Ingredients

The Peppers and Filling

• 6 large bell peppers (tops cut off and seeds removed)
• 1 lb (500g) ground lamb
• 1 tablespoon olive oil
• 1 medium onion, finely chopped
• 2 carrots, peeled and diced small
• 2 cloves garlic, minced
• 1 cup frozen peas
• 2 tablespoons tomato paste
• 1 tablespoon Worcestershire sauce
• 1 cup beef or lamb broth
• 1 teaspoon fresh thyme leaves
• 1 teaspoon fresh rosemary, chopped
• Salt and freshly ground black pepper to taste

The Topping

• 3 cups prepared mashed potatoes (creamy and seasoned)
• 1/2 cup sharp cheddar cheese, shredded
• 2 tablespoons melted butter (for brushing)
• Fresh parsley, chopped (for garnish)

Instructions

Step 1: Fire Up the Arteflame

1. Start your Arteflame grill by building a fire in the center. Allow it to burn down until the center grate is extremely hot (over 800°F) and the outer flat cooktop reaches a steady medium-high grilling temperature.
2. Lightly oil the flat cooktop with olive oil or butter to prepare it for sautéing the vegetables and meat.

Step 2: Prepare the Shepherd's Filling

1. Place the diced onions and carrots directly on the flat cooktop. Sauté them for about 5 minutes until they begin to soften.
2. Add the ground lamb to the cooktop. Use a spatula to break the meat apart, cooking until browned.
3. Mix in the minced garlic, thyme, and rosemary, cooking for another minute until fragrant.
4. Stir in the tomato paste and Worcestershire sauce, coating the meat and vegetables evenly.
5. Create a small well in the mixture and pour in the broth. Let it simmer on the flat top until the liquid reduces and thickens slightly. Finally, mix in the frozen peas and season with salt and pepper. Move the mixture to a cooler zone of the grill to keep warm.

Step 3: Stuff the Peppers

1. Take your prepared bell peppers and stand them upright. If they are wobbly, slice a very thin layer off the bottom to flatten them, ensuring you don't cut through to the inside.
2. Spoon the savory lamb mixture generously into each pepper, filling them about three-quarters of the way full.
3. Top each pepper with a large scoop of prepared mashed potatoes. Use a fork to rough up the surface of the potatoes (this helps them get crispy).
4. Sprinkle the shredded cheddar cheese over the mashed potatoes.

Step 4: Grill to Perfection

1. Brush the outside of the peppers lightly with olive oil. Place the stuffed peppers directly on the flat cooktop of the Arteflame.
2. Cook for 15 to 20 minutes. The goal is to char the bottoms and soften the peppers while heating the filling through.
3. If you want more browning on top, you can carefully move the peppers closer to the center fire for the last 2 minutes, or cover them with a basting dome to help the cheese melt and the peppers steam slightly.
4. Remove from the grill once the peppers are tender and the cheese is bubbly and golden. Garnish with fresh parsley before serving.

Tips

Cooking stuffed peppers on a grill requires a balance of heat to ensure the pepper softens without burning the bottom completely. To achieve this on the Arteflame, place the peppers on the outer ring of the cooktop where the heat is moderate. If you prefer your peppers very soft, you can blanch them in boiling water for 3 minutes before stuffing them, though the dry heat of the grill usually provides a perfect al dente texture that holds its shape better. For the mashed potatoes, using cold, leftover mash actually works better than fresh, hot mash as it is stiffer and easier to mound on top of the meat. Finally, make sure your lamb filling isn't too runny; reduce the broth sufficiently on the flat top so the peppers don't become soggy while cooking.

Variations

This recipe is incredibly versatile and can be adapted to suit various dietary preferences or flavor profiles. While traditional Shepherd's Pie uses lamb, you can easily swap proteins or add a twist to the toppings. Here are a few delicious ways to modify the dish for your next barbecue:

• Cottage Pie Style: Swap the ground lamb for ground beef for a traditional Cottage Pie version.
• Sweet Potato Twist: Replace the standard white mashed potatoes with mashed sweet potatoes for a colorful and slightly sweeter variation.
• Vegetarian Delight: Substitute the meat with cooked lentils or a plant-based ground meat alternative, using vegetable broth instead of beef broth.
• Spicy Kick: Add a chopped jalapeño to the onion and carrot sauté, and mix a teaspoon of paprika into the meat filling.
• Cheesy Crust: Mix parmesan cheese into the mashed potatoes and top with Gruyère instead of cheddar for a richer, nuttier crust.

Best pairings

To round out this hearty meal, you need sides and drinks that cut through the richness of the lamb and mashed potatoes. Since the peppers are a meal in themselves, sides should be light and refreshing. A crisp garden salad with a sharp vinaigrette—perhaps lemon and mustard based—works wonders to cleanse the palate. For a vegetable side, grilled asparagus or blistered green beans cooked right on the Arteflame alongside the peppers add a nice crunch. Beverage-wise, this dish screams for a drink with body. A classic Irish Stout or a dark Porter pairs beautifully with the savory lamb. If you prefer wine, a medium-bodied red like a Merlot or a Cotes du Rhône complements the herbaceous filling perfectly without overpowering the smoky grilled flavor.

Grilled Shepherd’s Pie Stuffed Peppers are a testament to the versatility of the Arteflame grill.
