Smoky Dutch Spiced Roasted Walnuts on the Grill

There is a beautiful concept in Dutch culture known as gezellig, a word that encompasses cozy, sociable, and enjoyable times spent with loved ones. Nothing captures this feeling quite like the aroma of warm spices wafting through the air on a crisp evening. While roasted nuts are a staple of holiday markets and winter fairs, taking them to the grill introduces a layer of complexity that the oven simply cannot replicate. The gentle smokiness from the fire interacts with the caramelized sugar and aromatic spices to create a snack that is deeply savory, perfectly sweet, and satisfyingly crunchy.

This recipe for Dutch Spiced Roasted Walnuts is designed for the outdoor cooking enthusiast who wants to elevate a simple snack into a gourmet experience. Using a blend of traditional Speculaas spices—warming cinnamon, cloves, and nutmeg—these walnuts are coated in a light meringue-like glaze that crisps up beautifully on the flat-top grill. Whether you are hosting a festive gathering, looking for a unique salad topper, or simply enjoying a glass of wine by the fire, these nuts are an effortless way to bring a touch of European charm to your backyard cooking.

Ingredients

The Nut Base

• 4 cups raw walnut halves
• 1 large egg white (room temperature)
• 1 teaspoon vanilla extract
• 1 teaspoon water

The Dutch Spice Blend

• 1/2 cup light brown sugar, packed
• 1/2 cup granulated white sugar
• 1 tablespoon ground cinnamon
• 1 teaspoon ground nutmeg
• 1/2 teaspoon ground cloves
• 1/2 teaspoon ground ginger
• 1/4 teaspoon ground white pepper (optional, for a traditional kick)
• 1/2 teaspoon sea salt

Instructions

Step 1: Prepare the Glaze and Spice Mix

1. In a small mixing bowl, combine the brown sugar, white sugar, cinnamon, nutmeg, cloves, ginger, white pepper, and sea salt. Whisk well to ensure the spices are evenly distributed throughout the sugar.
2. In a separate large bowl, whisk the egg white, vanilla extract, and water together until the mixture becomes frothy and bubbly. You do not need stiff peaks, just a nice foam to act as a binder.

Step 2: Coat the Walnuts

1. Pour the raw walnut halves into the bowl with the frothy egg white mixture.
2. Toss the walnuts gently with a rubber spatula until every nook and cranny of the nuts is coated in the liquid.
3. Sprinkle the dry sugar and spice mixture over the nuts. Toss again thoroughly until the walnuts are evenly coated in a sandy, spiced layer.

Step 3: Fire Up the Grill

1. Preheat your grill to a medium-low temperature. If you are using an Arteflame or similar flat-top grill, aim for the outer edges of the cooktop where the heat is gentler (around 300°F - 350°F).
2. Lightly oil the cooking surface with a neutral oil (like grapeseed or canola) to prevent sticking, though the sugar will naturally create a caramelized crust.

Step 4: Roast to Perfection

1. Spread the coated walnuts onto the flat cooktop in a single layer. Do not pile them up, or they will steam instead of roast.
2. Cook for approximately 10 to 15 minutes. It is crucial to keep the nuts moving; stir and flip them every minute or two to prevent the sugar from burning.
3. Watch closely—you want the sugar to melt and caramelize, and the nuts to become fragrant and toasted, but not blackened.

Step 5: Cool and Set

1. Once the coating has hardened slightly and the nuts are toasted, remove them from the grill immediately.
2. Spread them out on a baking sheet lined with parchment paper to cool. Separate them quickly with a fork so they don't clump together.
3. Allow them to cool completely. They will crisp up significantly as they reach room temperature.

Tips

The secret to perfect grilled nuts lies in temperature control. Sugar burns at 350°F (175°C), so managing your heat zones is critical. On a flat-top grill, keep the nuts away from the direct center fire; use the cooler outer ring to slowly roast the nut inside without scorching the sugary exterior. If you are cooking over an open grate rather than a griddle, utilize a grill basket or a cast-iron skillet to keep the nuts contained while still absorbing that delicious wood-fired flavor.

Humidity plays a role in the final texture. If you are grilling on a particularly humid day, the nuts might remain slightly tacky even after cooling. To fix this, you can pop them in a low-temperature oven (around 200°F) or back on the coolest part of the grill for a few minutes to dry out the moisture without cooking them further. Always store your cooled nuts in an airtight container to maintain that satisfying snap for up to two weeks—though they rarely last that long!

Variations

While the traditional Dutch spice profile is warm and sweet, this recipe is incredibly versatile. You can easily adapt the flavor profile to suit your palate or the occasion. The egg white binder technique works with almost any seasoning blend, allowing you to experiment with savory, spicy, or herbal notes. Here are a few creative twists to try on your next grill session:

• Spicy Kick: Add 1/2 teaspoon of cayenne pepper or smoked paprika to the sugar mix for a "swicy" (sweet and spicy) combo.
• Maple Glazed: Substitute the white sugar with maple sugar granules and add a teaspoon of maple extract for an autumnal vibe.
• Savory Herb: Omit the sugar entirely. Use egg whites, fresh chopped rosemary, thyme, sea salt, and cracked black pepper.
• Mixed Nuts: Don't limit yourself to walnuts; this method works perfectly with pecans, almonds, or a mixed nut blend.
• Citrus Twist: Add the zest of one fresh orange to the sugar mixture for a bright, zesty contrast to the warm cloves.

Best pairings

These Dutch Spiced Roasted Walnuts are a powerhouse of flavor, making them an excellent companion for various beverages and dishes. Their rich, caramelized profile cuts through creamy textures and complements bold drinks. Serving them warm right off the grill adds an extra element of hospitality that your guests will love. Here are some ideal ways to pair and serve them:

• Cheese Boards: Pair with creamy cheeses like Brie, Camembert, or an aged Gouda to contrast the sweet crunch.
• Winter Beverages: Serve alongside a dark Stout beer, a glass of bold Cabernet Sauvignon, or a steaming mug of mulled wine (Glühwein).
• Dessert Toppings: Crumbled over vanilla bean ice cream or a grilled peach salad.
• Breakfast Upgrade: A perfect crunchy topping for Greek yogurt or oatmeal.
