Preheat your oven to 400°F (200°C) and line a baking sheet with parchment. Trim and halve your Brussels sprouts, removing any discolored leaves. This ensures even roasting and a clean presentation.
Toss the halved sprouts with olive oil, maple syrup or honey, sea salt, and black pepper. Make sure each sprout is evenly coated to create crisp, caramelized edges during roasting.
Arrange sprouts cut-side down on the baking sheet. Roast for 25–30 minutes, flipping halfway through. They should be tender inside with golden, crispy edges that smell irresistible.
While sprouts roast, toast the walnuts in a dry skillet over medium heat for 2–3 minutes, stirring often. Toasting enhances flavor and aroma, making your glaze extra special.
Warm honey and apple cider vinegar in a small saucepan until bubbling. Stir in the toasted walnuts, then remove from heat. The glaze should coat the back of a spoon and cling to the skewers beautifully.
Thread 4–5 roasted sprouts onto each wooden skewer. Their caramelized edges and vibrant green color make them visually striking, perfect for a festive table.
Drizzle the warm walnut honey glaze over the skewers and sprinkle with fresh thyme if desired. Serve immediately for maximum shine and flavor.
