The combination of the hot, buttered plancha surface and the fresh zest of lemon creates a culinary masterpiece that pays homage to traditional Belgian fishmongers.

Ingredients

To recreate this authentic Belgian classic, you will need fresh, high-quality ingredients. The sauce relies on the richness of the dairy, so opt for full-fat versions for the best texture.

• 4 whole trout, cleaned and gutted (heads on or off based on preference)
• 1 lemon, juiced
• Salt and freshly ground black pepper to taste
• 3/4 cup all-purpose flour
• 4 oz unsalted butter, divided
• 1/2 cup heavy cream
• 1 egg yolk
• 1 tbsp fresh thyme leaves, chopped (or parsley if preferred)

Instructions

Step 1: Prepare the Trout

1. Begin by rinsing the trout thoroughly under cold water and patting them completely dry with paper towels. Dry skin is essential for a crispy sear.
2. Season the trout generously inside and out with salt and freshly ground black pepper.
3. Squeeze the fresh lemon juice over the fish, ensuring it coats the skin and the cavity.
4. Place the flour in a shallow dish. Dredge each trout in the flour, shaking off any excess so you have a light, even coating.

Step 2: Fire Up the Arteflame

1. Build a medium-sized fire in the center of your Arteflame grill. You want to aim for a medium-high heat on the flat cooktop (plancha) surface.
2. Allow the cooktop to heat up evenly. Apply a thin layer of vegetable oil to season the steel before you begin cooking with butter.

Step 3: Grill the Trout

1. Melt half of the butter (2 oz) directly on the flat cooktop surface where you intend to cook the fish.
2. Once the butter foams but before it burns, place the floured trout onto the grill.
3. Grill the trout for approximately 5 to 7 minutes per side, depending on thickness. You are looking for a golden-brown, crispy crust and flesh that flakes easily with a fork.
4. Once cooked, move the trout to the outer, cooler edges of the grill to keep warm while you prepare the sauce.

Step 4: Prepare the Creamy Thyme Sauce

1. On a clean section of the cooktop (or in a small cast-iron skillet placed on the grill), melt the remaining 2 oz of butter.
2. In a small bowl, whisk together the heavy cream and the egg yolk until smooth.
3. Slowly pour the cream mixture into the melted butter, stirring constantly to prevent the egg from scrambling.
4. Add the chopped fresh thyme (or parsley) to the sauce.
5. Stir gently until the sauce thickens slightly and is heated through. Do not let it boil vigorously.

Step 5: Serve

1. Plate the trout immediately.
2. Pour the warm creamy thyme sauce generously over the fish.
3. Garnish with a slice of lemon or a sprig of fresh thyme.

Tips

Mastering the heat on your Arteflame is the secret to this recipe's success. Because trout is a delicate fish, you want to avoid the hottest inner ring of the cooktop, which might burn the flour coating before the fish is cooked through. Stick to the middle zone of the plancha for a steady, even sear. When making the sauce, temperature control is vital; if the butter is too hot, the egg yolk in the cream mixture will curdle. If you are worried about this, you can temper the egg mixture by adding a spoonful of the warm butter to the bowl before pouring it all onto the grill. Additionally, ensure your trout is bone-free or warn your guests to be careful, as whole fish often retain fine bones. Using clarified butter (ghee) for the initial fry can also help prevent burning solids if your grill is running very hot.

Variations

While the classic Belgian approach relies on the earthy aroma of thyme and the richness of cream, this recipe is wonderfully adaptable to suit your palate or the season. You can easily swap the protein or the herbs to create a distinctively different flavor profile while using the same wood-fired technique. Here are a few delicious ways to mix it up:

• Trout Amandine: Skip the cream and egg. Instead, brown sliced almonds in the butter on the grill and pour over the fish with extra lemon juice.
• Dill & Caper: Replace the thyme with fresh dill and add a tablespoon of capers to the sauce for a brinier, zestier finish.
• Bacon-Wrapped: Wrap the trout in thin slices of bacon before grilling for a smoky, savory crust that eliminates the need for flour.
• The Ardennes Style: Add a splash of white wine and sautéed mushrooms to the sauce for an earthier, forest-inspired variation.
• Spicy Kick: Add a pinch of cayenne pepper or paprika to the flour dredge for a subtle heat that cuts through the rich cream sauce.

Best pairings

Since this dish features a rich, velvety sauce and smoky fish, you want side dishes that can either cut through the richness or help sop up every delicious drop. Belgian cuisine is famous for its potatoes, making them a natural choice. However, fresh greens grilled alongside the fish add color and balance to the plate.

• Belgian Frites: Thick-cut, double-fried potatoes served with mayonnaise are the most traditional accompaniment.
• Grilled Asparagus: Toss asparagus spears in oil and grill them right next to the trout for a charred, fresh side.
• Boiled Baby Potatoes: Tossed with parsley and butter, these are perfect for absorbing the thyme cream sauce.
• Crisp White Wine: A dry Riesling, Sauvignon Blanc, or a Belgian blonde ale pairs perfectly with the buttery trout.
• Crusty Baguette: Essential for cleaning the plate of any remaining sauce.

Conclusion

Mastering this Belgian wood-grilled trout on the Arteflame is about more than just cooking dinner; it is about embracing a slower, more intentional style of dining. The combination of smoky, crispy skin and the velvety thyme sauce creates a symphony of textures and flavors that feels like a meal served at a high-end Brussels bistro. The Arteflame makes the process seamless, allowing you to prepare the fish and the delicate sauce side-by-side in the open air. Gather your friends, pour a glass of cold white wine, and enjoy the rustic elegance of this timeless European dish.
