Authentic Belgian Grilled Chestnuts with Sea Salt

There is something undeniably magical about the scent of roasting chestnuts wafting through the crisp air of a Belgian winter market. It evokes a sense of nostalgia, comfort, and the festive spirit of the holiday season. While street vendors in Brussels often roast these over open drums, you can recreate this rustic, smoky delicacy right in your backyard using your Arteflame grill. The high heat of the plancha cooktop is perfect for blistering the shells while keeping the inside tender and sweet. This recipe for Belgian Grilled Chestnuts with Sea Salt is incredibly simple, relying on the quality of the nuts and the precise application of heat to transform a humble ingredient into a sophisticated, savory snack. Whether you are hosting a winter barbecue or simply gathering around the fire pit for warmth, these roasted gems offer a buttery texture and a nutty flavor that pairs perfectly with the smokiness of the grill.

Ingredients

• 1 lb Fresh Chestnuts (look for firm, shiny shells with no holes)
• 2 tbsp Unsalted Butter (melted) or high-quality Olive Oil
• 1 tbsp Coarse Sea Salt or Fleur de Sel
• Fresh Rosemary sprigs (optional, for aromatic infusion)

Instructions

Step 1: Prep and Score the Chestnuts

1. Begin by washing the chestnuts thoroughly in cold water to remove any dust or debris.
2. Dry them completely with a clean towel.
3. Using a sharp paring knife or a specialized chestnut knife, carefully cut an "X" into the rounded side of each chestnut.
4. Ensure you cut through the tough outer shell but try to avoid cutting deep into the nut meat itself. This step is crucial as it allows steam to escape, preventing the chestnuts from exploding on the grill, and makes peeling them significantly easier later.

Step 2: Fire Up the Arteflame

1. Start a fire in the center of your Arteflame grill using wood or charcoal.
2. Allow the grill to heat up until the center grate is hot and the outer flat cooktop reaches a medium-high temperature.
3. If you want a more aromatic smoke, add a piece of hickory or apple wood to the fire.
4. Lightly oil the flat cooktop surface where you plan to place the chestnuts to ensure they don't stick and to help conduct heat.

Step 3: Grill the Chestnuts

1. Toss the scored chestnuts in the melted butter (or olive oil) until they are lightly coated.
2. Place the chestnuts on the flat cooktop surface of the Arteflame. You can also use a grill basket over the open flame for a smokier flavor, but the flat top provides more even roasting.
3. Grill for approximately 15 to 20 minutes, tossing them every few minutes with a spatula or tongs.
4. You will know they are done when the shells have darkened, the "X" cut has curled open significantly to reveal the yellow nut inside, and the nut meat feels tender when squeezed (wear a heat-resistant glove).

Step 4: Season and Steam

1. Remove the chestnuts from the grill and immediately toss them in a bowl with the coarse sea salt while they are still piping hot.
2. Transfer the seasoned chestnuts to a paper bag or wrap them tightly in a clean kitchen towel for about 5 to 10 minutes.
3. This "steaming" step is the secret to easy peeling; the trapped moisture helps the inner skin (pellicle) separate from the nut meat.
4. Serve immediately while warm, encouraging guests to peel and eat them by hand.

Tips

To ensure the best experience with your Belgian grilled chestnuts, freshness is key. When buying chestnuts, give them a gentle shake; if you hear rattling, the nut has dried out and shriveled inside, so avoid those. The scoring process is the most dangerous part of the recipe, so ensure your chestnuts are stable on the cutting board; placing them on a damp cloth can stop them from rolling away while you cut. If you are struggling to peel the inner fuzzy skin, the chestnuts likely weren't roasted long enough or didn't steam in the towel for the full ten minutes. For an extra touch of authenticity, serve them in paper cones just like you would find on the streets of Europe. This not only keeps your hands warm but adds to the communal, street-food aesthetic of the dish.

Variations

While the classic sea salt version is a staple in Belgium, chestnuts are a versatile canvas for flavor. You can easily adapt this recipe to lean towards sweet or spicy profiles depending on your mood. The Arteflame’s searing capability works well for glazing nuts near the end of the cooking process. Here are a few ways to mix things up:

• Sweet Cinnamon Glaze: Toss the roasted nuts in melted butter, brown sugar, and cinnamon right before serving.
• Spicy Kick: Mix chili powder or cayenne pepper with the sea salt for a warming heat.
• Herbal Infusion: Place fresh rosemary or thyme sprigs directly on the grill surface with the nuts to infuse them with smoke and oils.
• Bacon Fat Roast: Substitute butter with rendered bacon grease for an intensely savory, smoky flavor.
• Truffle Essence: Finish with a drizzle of truffle oil and parmesan cheese for a gourmet twist.

Best pairings

Grilled chestnuts are rich, starchy, and slightly sweet, making them a robust snack that requires a beverage capable of cutting through the density. In Belgium, this street food is almost always accompanied by a warm drink to combat the cold. If you are serving these as an appetizer or a late-night fireside snack, consider beverages that complement roasted and nutty notes. The saltiness of the preparation also calls for something with a bit of body or acidity to cleanse the palate.

• Mulled Wine (Glühwein): The spices in the hot wine perfectly mirror the wintery vibe of chestnuts.
• Belgian Dark Strong Ale: A beer like a Chimay Blue or Rochefort 10 offers caramel notes that harmonize with the roasted nuts.
• Hot Chocolate: A rich, dark hot cocoa is the perfect non-alcoholic pairing.
• Aged Gouda: Serve alongside a cheese board with sharp, aged cheeses to contrast the sweetness of the nuts.
