Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside.
Place ½ cup of dried cranberries in a cup of hot water and set aside. (this gives the dried cranberries a little plump)
Toss together brussels sprouts, oil, salt, and pepper. Spread evenly on the prepared baking sheet.
Roast for 15 minutes. Remove the pan from the oven, stir, and add the pecans and cranberries (drain the cranberries before adding) and cook for 5 minutes more or until the pecans are lightly toasted.
