The Ultimate Grilled Beef Wellington Recipe for Arteflame

Introduction

There are few dishes in the culinary canon that commands respect quite like Beef Wellington. Traditionally reserved for high-end steakhouses or ambitious home oven roasts, bringing this masterpiece to the Arteflame grill transforms it into an unforgettable outdoor experience. By utilizing the Arteflame’s unique heat distribution, we take the classic components—tender filet mignon, earthy mushroom duxelles, salty prosciutto, and buttery puff pastry—and infuse them with a whisper of wood-fired flavor that an indoor oven simply cannot replicate.

Many home cooks find the Wellington intimidating, fearing a soggy bottom or overcooked meat. However, the Arteflame cooktop offers precise control, allowing you to sear the beef to perfection and evaporate moisture from the mushrooms rapidly on the flat top before assembly. This recipe is designed to guide you through crafting a restaurant-quality centerpiece that is golden, crispy, and perfectly medium-rare, serving as the ultimate showstopper for your next holiday gathering or special occasion dinner.

Ingredients

The Core Components

• 2 lbs center-cut beef tenderloin (filet mignon roast), trimmed
• 1 sheet frozen puff pastry, thawed but cold
• 10-12 slices Prosciutto di Parma
• 2 tbsp Dijon mustard
• 1 egg, beaten (for egg wash)
• Sea salt and freshly cracked black pepper
• 2 tbsp olive oil (for rubbing the meat)

Mushroom Duxelles

• 1 lb mixed mushrooms (cremini, shiitake, or button), finely chopped
• 2 shallots, minced
• 2 cloves garlic, minced
• 2 tbsp unsalted butter
• 1 tbsp fresh thyme leaves, chopped
• Splash of dry white wine (optional)

Instructions

Step 1: Searing the Beef

1. Fire up your Arteflame grill. You want a high-heat center for searing.
2. Season the beef tenderloin generously with salt and pepper.
3. Place the tenderloin directly on the center grill grate or the hottest part of the plancha cooktop. Sear on all sides for about 1-2 minutes per side until browned. Do not cook it through; you only want a crust.
4. Remove the beef from the grill and immediately brush it with the Dijon mustard while it is still hot. Set aside to rest and cool completely.

Step 2: Preparing the Duxelles

1. On the flat top plancha surface, melt the butter near the center (medium-high heat).
2. Add the finely chopped mushrooms, shallots, and garlic. Cook, stirring frequently, until the mushrooms release their liquid.
3. Continue cooking until the liquid has completely evaporated and the mixture is dry (this is crucial to prevent soggy pastry).
4. Stir in the fresh thyme and season with salt and pepper. Remove from the grill and let it cool completely.

Step 3: Assembly

1. Lay out a large piece of plastic wrap on a flat surface. Shingle the prosciutto slices on the plastic so they overlap slightly, forming a rectangle large enough to encase the beef.
2. Spread the cooled mushroom duxelles evenly over the prosciutto.
3. Place the cooled beef tenderloin at the bottom of the rectangle. Using the plastic wrap, roll the beef up tightly in the prosciutto and mushrooms. Twist the ends of the plastic to secure it into a tight log. Chill in the fridge for 20 minutes to set shape.
4. Roll out the puff pastry slightly. Remove the plastic from the beef log and place it in the center of the pastry. Brush the edges with egg wash.
5. Fold the pastry over the beef, sealing the edges. Place seam-side down. Brush the entire exterior with egg wash and score the top lightly with a knife for decoration.

Step 4: The Final Bake

1. Prepare the Arteflame for indirect cooking or baking. If you have a baking cover or dome, this is the time to use it. If not, manage a medium heat zone on the outer ring.
2. Place the Wellington on a baking sheet or a raised rack on the flat top (avoid direct contact with the hottest steel to prevent burning the bottom). Cover with a dome or large metal lid.
3. Bake for 25-35 minutes, rotating occasionally for even heat, until the pastry is golden brown and the internal temperature of the beef reaches 125°F (for medium-rare).
4. Remove from heat and let rest for at least 10 minutes before slicing.

Tips

The secret to a perfect Beef Wellington lies in moisture control and temperature management. The most common mistake is not cooking the moisture out of the mushrooms sufficiently; on the Arteflame, the open air and high heat of the plancha make it easier to get a truly dry duxelles, which ensures your pastry stays flaky and crisp from the inside out. Furthermore, ensure your beef is completely cool before wrapping it in the pastry; if it is warm, it will melt the puff pastry butter layers before they hit the heat, ruining the puff.

When baking on the grill, the challenge is ensuring the pastry cooks through before the beef overcooks. Using a meat thermometer is non-negotiable here. Pull the Wellington when the internal temperature hits 125°F, as carryover cooking during the resting phase will bring it up to a perfect medium-rare 130-135°F. Always let the meat rest for at least 10 minutes to allow the juices to redistribute, otherwise, they will run out and soften your crust immediately upon slicing.

Variations

While the classic recipe is timeless, the versatility of the Arteflame allows for creative twists that can cater to different palates or dietary preferences. You can easily swap proteins or add different flavor profiles to the duxelles to make the dish your own. Here are a few ways to remix this classic:

• Venison Wellington: Swap the beef for a venison loin for a gamey, rich flavor that pairs beautifully with the wood smoke.
• Individual Wellingtons: Instead of one large roast, use filet mignon steaks to make individual portions, reducing cooking time.
• Vegetarian Beet Wellington: Use roasted whole beets or a savory nut roast as the center instead of beef.
• Truffle Infusion: Add truffle oil or black truffle paste to the mushroom duxelles for an earthy, luxurious kick.
• Pork Tenderloin: A more budget-friendly option that works wonderfully with a layer of cooked apple in the duxelles.

Best pairings

Because Beef Wellington is such a rich and decadent dish, it requires sides and drinks that can stand up to its intensity without overshadowing it. The buttery pastry and savory meat call for accompaniments that offer acidity or earthiness. Since you are already cooking on the Arteflame, utilize the flat top to prepare your sides simultaneously while the Wellington rests. This not only saves time but ensures the entire meal has a cohesive flavor profile.

For wine, a bold, tannic red is essential. A Cabernet Sauvignon, Bordeaux blend, or a robust Syrah will cut through the richness of the puff pastry and prosciutto. For side dishes, consider these options:

• Grilled Asparagus: Wrapped in lemon zest and charred quickly on the plancha.
• Roasted Root Vegetables: Carrots and parsnips glazed with honey and thyme, roasted on the outer ring.
• Garlic Mashed Potatoes: Creamy and smooth to complement the crunch of the pastry.
• Balsamic Glazed Brussels Sprouts: Charred on the grill to add a bitter-sweet contrast.

Conclusion

Mastering Beef Wellington on the Arteflame is a culinary achievement that blends the refinement of fine dining with the primal joy of live-fire cooking. It pushes the boundaries of what is expected from a grill, proving that your outdoor kitchen is capable of far more than just burgers and steaks. The result is a dish that is visually stunning, texturally complex, and bursting with flavor—a true centerpiece that demands conversation and praise.

We hope this recipe inspires you to try something ambitious for your next gathering. The combination of the smoky sear, the savory duxelles, and the golden pastry is truly unmatched. Fire up your Arteflame, pour a glass of wine, and enjoy the process of creating a legendary meal that your friends and family will talk about for years to come.
