Preheat oven to 400 degrees and spray a rimmed baking sheet with cooking spray.
Trim stems and peel off any damaged leaves from Brussels sprouts. Halve any sprouts that are large in size and place in a large mixing bowl. Drizzle with olive oil then toss to coat completely.
Transfer the sprouts to a rimmed baking sheet and sprinkle evenly with salt and pepper. Bake 18–30 minutes depending on size and desired tenderness. Be sure to shake the pan halfway through roasting to ensure the sprouts cook evenly. Remove from oven when sprouts are dark on the outside with a few crispy leaves and as tender as you like on the inside.
Remove from the oven and transfer to a serving bowl. Toss with dried cranberries, test for seasoning then serve and enjoy!
Notes
Brussels sprouts are one of the healthiest foods that you can eat and they’re available all year long!
