Preheat your oven to 375 degrees.
You can choose to leave your Brussel sprouts whole or cut them in half. I usually leave them whole for this dish unless my Brussel sprouts are really large. Arrange the Brussel sprouts on your baking sheet(s) & toss with olive oil. Sprinkle with garlic salt & pepper.
Roast for about 25-30 minutes, but if you have small Brussel sprouts or you cut them in half, start checking on them after 20 minutes as they can cook faster.
Drizzle the Brussel sprouts with the balsamic glaze. Sprinkle on the dried cranberries. Toss & serve immediately.
