Parmesan brussels sprouts are an easy side dish to pair with your next main dish. They're coated in olive oil, garlic, and parmesan cheese, then roasted until tender and caramelized in the oven.
Preheat oven to 400℉. Line a baking sheet with parchment paper and set aside.
Add brussels sprouts to a large bowl. Drizzle with olive oil, then add garlic powder, salt, pepper, and parmesan cheese. Toss until evenly coated. Pour brussels sprouts onto prepared baking sheet and spread into a single layer. It's okay if some leaves fall off, they can be roasted as well.
Roast brussels sprouts in the oven for about 20-25 minutes, or until brussels sprouts are browned to your liking and fork tender (this depends entirely on the size and shape of your brussels sprouts).
Remove from oven and serve warm. Optionally, sprinkle more parmesan cheese on top before serving.

Notes
Small brussels sprouts: If your brussels sprouts are small, you may want to leave them whole. Slice medium to large brussels sprouts in half for quicker cooking in the oven.
Vegan variation: Parmesan cheese can be substituted with a vegan parmesan cheese or omitted entirely.
Leftovers: Leftover brussels sprouts will keep for 3 to 4 days in a tightly sealed container in the refrigerator.
