Creating Garlic Parmesan Roasted Brussels Sprouts is straightforward. Just follow these easy steps to achieve the most delightful results:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Brussels Sprouts: Rinse the Brussels sprouts under cold water. Trim the stem ends and remove any yellow or damaged leaves. Cut them in half, lengthwise.
3. Mix Ingredients: In a large bowl, combine the Brussels sprouts, olive oil, minced garlic, salt, and pepper. Toss until the sprouts are well coated.
4. Spread on Baking Sheet: Arrange the coated Brussels sprouts in a single layer on a large baking sheet. Make sure they have enough space to roast evenly.
5. Roast the Brussels Sprouts: Place the baking sheet in the preheated oven and roast for 20–25 minutes, shaking the pan halfway through for even cooking.
6. Add Parmesan: In the last 5 minutes of roasting, sprinkle the grated Parmesan cheese over the Brussels sprouts and return to the oven. Allow the cheese to melt and turn a golden color.
7. Finish and Garnish: Once they are nicely browned and crispy, remove from the oven. If desired, sprinkle crushed red pepper flakes and garnish with fresh parsley before serving.

By following these steps, you can create a side dish that looks as good as it tastes!
