Preheat your oven to 400?F (200?C) and line a baking sheet with parchment paper or foil.

Trim and halve the Brussels sprouts, removing any damaged outer leaves. Toss them in a large bowl with olive oil, salt, and pepper.

Spread the Brussels sprouts on the baking sheet in a single layer with the cut side down.

Roast the Brussels sprouts in the preheated oven for about 20-25 minutes, stirring halfway through for even crisping.

While the Brussels sprouts are roasting, prepare the honey butter glaze by melting butter in a small saucepan over medium heat.

Add honey and soy sauce, stirring until blended. If desired, add crushed red pepper flakes.

Let the glaze simmer for about 1-2 minutes, then remove from heat.

Once roasted, remove the Brussels sprouts from the oven and place them in a large bowl.

Pour the warm honey butter glaze over them and gently toss to coat.

Transfer the glazed Brussels sprouts to a serving dish and serve hot.
