Preheat the oven to 400°F and line a sheet pan with parchment paper.
Cut off the ends of the sprouts and separate any freed leaves. Cut the sprouts in half or quarters, depending on size.
In a large bowl whisk together the oil, maple syrup, vinegar, salt, and pepper.
Toss the mixture with the cut brussel sprouts and leaves.
Place the sprouts, cut side down, on the parchment and arrange the leaves in the center of the sheet pan. Reserve the extra maple syrup mixture in the bowl.
Roast for 30-35 minutes in the hottest part of the oven, tossing after 20 minutes.
Toss the cooked brussel sprouts and leaves with the remaining maple syrup mixture and then transfer them to a serving dish. Serve hot.
