Charred Pembrokeshire Potatoes (Welsh Style) | Arteflame

Introduction

Imagine the intoxicating aroma of sizzling butter and fresh mint drifting through your backyard on a warm evening. These Fire-Grilled Welsh Potatoes offer a sensory experience that boiling simply can't match—crispy, golden skins that snap upon the first bite, revealing a creamy, earthy center. It is the kind of rustic, comfort food that turns a standard barbecue into a memorable feast, evoking memories of seaside dining and the simple joy of open-fire cooking.

Why I Love This Dish

While new potatoes are often relegated to a simple boil, finishing them on the Arteflame grill transforms them completely. The high heat of the carbon steel cooktop caramelizes the natural sugars, adding a depth of flavor and a delightful crunch that perfectly contrasts with the fresh, herbaceous kick of mint. It is an effortless side dish that feels incredibly gourmet, bridging the gap between traditional Welsh heritage and modern outdoor grilling.

Tips for Success

• Par-boil is non-negotiable: Pre-cooking ensures the insides are fluffy before the skins burn on the high heat.
• Watch the butter: Add your Welsh butter at the very end in a cooler zone to prevent the milk solids from burning and becoming bitter.
• Don't crowd the cooktop: Give the potatoes space to breathe so they roast and crisp rather than steam.

Ingredient Substitutions

If you can't find specific Pembrokeshire earlies, any high-quality waxy new potato works beautifully. For a dairy-free version, swap the butter for duck fat or additional high-heat oil to keep that luxurious mouthfeel without the dairy.

Ingredients

Main Components

• 2 lbs (1kg) Pembrokeshire Early potatoes (or high-quality new potatoes)
• 4 tbsp Welsh salted butter, cubed
• 2 tbsp high-heat oil (such as grapeseed or avocado oil) for the grill
• 1 bunch of fresh garden mint, finely chopped
• 2 cloves of garlic, minced
• 1 tsp coarse sea salt (Halen Môn is preferred for authenticity)
• 1/2 tsp freshly cracked black pepper

Instructions

Step 1: Preparation and Par-Boiling

1. Begin by thoroughly washing your Pembrokeshire potatoes to remove any loose soil, but do not peel them. The delicate skins are packed with flavor and nutrient value.
2. Place the potatoes in a large pot of cold, salted water. Bring the water to a boil over high heat, then reduce to a simmer.
3. Cook for approximately 10 to 12 minutes, or until the potatoes are just fork-tender but not falling apart. Drain them immediately and let them steam dry in the colander for 5 minutes. This step ensures the insides are fluffy while the outside dries out enough to crisp up on the grill.

Step 2: Firing Up the Arteflame

1. Build a medium-sized fire in the center of your Arteflame grill. You want to establish a solid bed of coals to heat the carbon steel cooktop.
2. Wait for the cooktop to reach a searing temperature. The center ring will be the hottest, while the outer edges offer a more moderate heat. Wipe the cooktop down with a little oil to clean and prep the surface.

Step 3: Searing the Potatoes

1. Slice the larger potatoes in half lengthwise; leave the smaller ones whole. Toss them lightly in the high-heat oil to coat the skins.
2. Place the potatoes cut-side down directly onto the flat cooktop. Aim for a medium-high heat zone rather than the direct center to avoid burning the skins before they crisp.
3. Let them sear undisturbed for 4 to 6 minutes. You are looking for a deep, golden-brown crust to form on the cut side.

Step 4: Flavor Infusion

1. Once the potatoes have a beautiful crust, flip them over to warm the rounded side. Move them slightly further from the center fire to a cooler zone.
2. Add the cubed Welsh butter directly onto the plancha next to the potatoes, allowing it to melt and foam. Toss the minced garlic into the butter, stirring briefly for 30 seconds until fragrant.
3. Using your spatula, toss the potatoes in the garlic butter right on the grill surface, ensuring every potato is coated in the rich, savory mixture.

Step 5: Finishing and Serving

1. Continue to cook for another 2 to 3 minutes, allowing the potatoes to absorb the butter and garlic flavors.
2. Sprinkle generously with the coarse sea salt and cracked black pepper.
3. Just before removing from the heat, scatter the fresh chopped mint over the potatoes and give them one final toss. Remove from the grill immediately and serve hot.

Tips

The secret to perfect grilled new potatoes lies in the par-boil. If you attempt to cook raw potatoes entirely on the grill, the skins will often burn before the center is cooked through. By par-boiling, you ensure a creamy, fully cooked interior, allowing the grill to focus solely on creating that irresistible Maillard reaction on the surface. When draining the potatoes, shaking them gently in the colander creates micro-textures on the skin, which trap the butter and crisp up beautifully on the steel cooktop.

Temperature management on the Arteflame is also key for this recipe. Butter has a low smoke point, which is why it is introduced at the end of the cooking process in a cooler zone of the grill. If you add the butter too early or too close to the center fire, the milk solids will burn, resulting in a bitter taste. Always use a neutral high-heat oil for the initial sear, saving the rich Welsh butter for the final flavor infusion. Don't be shy with the salt; potatoes require generous seasoning to bring out their natural earthiness.

Variations

While the classic combination of butter and mint is traditional for Pembrokeshire potatoes, the versatility of the Arteflame allows for creative twists. You can easily adapt the flavor profile to match whatever protein you are grilling alongside the potatoes. The robust nature of new potatoes means they can handle strong spices and rich fats without losing their identity. Experimenting with different herbs or fats can transform this side dish from a Welsh classic into a global fusion experience.

• Duck Fat Roasties: Swap the butter for duck fat for an incredibly decadent, crispy exterior.
• Smoked Paprika & Chorizo: Add diced chorizo and a teaspoon of smoked paprika during the final toss for a Spanish flare.
• Lemon & Dill: Replace the mint with fresh dill and squeeze half a grilled lemon over the potatoes just before serving.
• Smashed Garlic Parmesan: Gently smash the potatoes on the grill with a spatula and top with grated Parmesan cheese until melted.
• Spicy Rosemary: Use rosemary sprigs instead of mint and add a pinch of chili flakes for a warming kick.

Best pairings

Pembrokeshire potatoes are incredibly versatile, but they shine brightest when paired with dishes that complement their earthy, buttery profile. Traditionally, they are the perfect partner for Welsh lamb. The sweetness of the lamb fat and the brightness of the mint on the potatoes create a harmony that is hard to beat. Grilled lamb chops or a slow-roasted leg of lamb cooked on the rotisserie attachment of your Arteflame would make for an unforgettable meal. The smokiness from the grill ties the meat and vegetables together seamlessly.

Beyond lamb, these potatoes are an excellent accompaniment to fresh seafood. A whole grilled trout or cedar-plank salmon benefits from the substantial texture of the potatoes. For a vegetarian option, pair them with grilled asparagus and halloumi cheese. The salty cheese contrasts wonderfully with the sweet potato flesh. If you are serving a heavy steak, like a Ribeye or Porterhouse, the fresh mint on these potatoes acts as a palate cleanser, cutting through the richness of the beef fat effectively.

Conclusion

Fire-grilled Welsh Pembrokeshire potatoes are more than just a side dish; they are a celebration of seasonal produce and outdoor cooking. By utilizing the unique heat zones of the Arteflame, you achieve a texture that is difficult to replicate in a standard kitchen kitchen—crispy, caramelized skins giving way to a buttery, soft center. The addition of fresh mint and high-quality salted butter pays homage to the ingredient's heritage while the smoke adds a modern, rustic dimension.
