Ina Garten's Roasted Brussels Sprouts with Balsamic

Roasted with olive oil, salt, and pepper, Ina Garten's roasted Brussels sprouts are simple and delicious.
A few notes: The original recipe calls for pancetta. I find when I make these roasted Brussels sprouts without the pancetta, I don’t miss it. But when I make the Brussels sprouts with the pancetta, they are especially delicious. Your choice!
The original recipe also calls for syrupy balsamic vinegar, which can be expensive. Here, I've reduced 1/2 cup balsamic vinegar by half instead.
