Preparation of Brussels Sprouts

1. Preheat Oven: Set your oven to 400°F (205°C) to ensure it’s hot enough for roasting.
2. Toss Sprouts: In a mixing bowl, combine Brussels sprouts with olive oil, salt, and pepper. Ensure each sprout is evenly coated.
3. Roast: Spread the sprouts on the cast iron skillet in a single layer. Roast for 20-25 minutes or until they’re golden and crispy on the edges.

Making the Glaze

1. Combine Ingredients: In a small saucepan, whisk together balsamic vinegar, honey, and rosemary over medium heat.
2. Reduce: Let the mixture simmer until it thickens into a glaze, about 10 minutes. Stir occasionally to prevent burning.

Finishing Touches

1. Combine: Once the Brussels sprouts are roasted, drizzle the rosemary balsamic glaze over them.
2. Garnish: Sprinkle chopped pecans and grated Parmesan (if using) over the top.
