Creating Roasted Brussels Sprouts with Parmesan is a straightforward process. Follow these easy steps to achieve a perfect side dish:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C). This high temperature is crucial for achieving that golden-brown exterior.
2. Prepare Brussels Sprouts: Rinse the Brussels sprouts and trim the ends. Remove any yellow or damaged leaves.
3. Cut in Half: Slice each Brussels sprout in half lengthwise to allow for even cooking.
4. Toss with Oil and Seasoning: In a large bowl, combine the halved Brussels sprouts, olive oil, garlic powder, salt, and black pepper. Toss until the sprouts are evenly coated.
5. Spread on Baking Sheet: Arrange the seasoned Brussels sprouts on a baking sheet in a single layer, cut side down. This allows for optimal browning.
6. Roast: Place the baking sheet in the preheated oven. Roast for 20-25 minutes, or until they are golden brown and crispy on the edges. Stir halfway through for even cooking.
7. Add Parmesan: Remove the sprouts from the oven and sprinkle the grated Parmesan cheese evenly over them. Return to the oven for an additional 5 minutes to melt and slightly crisp the cheese.
8. Serve: Once finished, take them out and drizzle with fresh lemon juice if desired. Serve warm.

Following these steps ensures a delicious and satisfying side dish that elevates any meal.
