Preheat the oven to 400℉ (205℃).
Trim the ends of the Brussels sprouts, remove dry or bruised leaves, and peel away loose outer leaves. Cut each one in half through the stem, and place in a large bowl.
In a medium skillet, heat the butter over medium heat until fragrant and golden brown, 4-5 minutes, being careful not burn it. Let it cool slightly.
In a small bowl, mix the browned butter, balsamic vinegar, and honey.
Sprinkle the sprouts with salt, pepper, and Creole seasoning, followed by half of the balsamic honey mixture. Toss to coat.
Arrange them cut-side down on a baking sheet lined with parchment paper and place them on the middle rack in the oven.
Roast until tender, 20-25 minutes, stirring once or twice. Taste as you go, and add more of the dressing and seasonings as desired.
Serve immediately with the rest of the dressing on the side.
