Creating marinated Brussels sprouts is an easy and rewarding process. Follow these steps to achieve perfect results:

1. Prepare the Brussels Sprouts: Rinse the Brussels sprouts under cold water. Trim the stems and remove any damaged outer leaves.
2. Halve the Sprouts: Cut each Brussels sprout in half to allow for better marination and cooking.
3. Make the Marinade: In a large bowl, whisk together the olive oil, balsamic vinegar, minced garlic, honey, Dijon mustard, salt, and black pepper until well combined.
4. Add the Sprouts: Place the halved Brussels sprouts into the bowl with the marinade. Toss to ensure that each piece is well-coated with the mixture.
5. Marinate: Cover the bowl with plastic wrap or a lid and let the sprouts marinate in the refrigerator for at least 30 minutes. For best results, marinate them for 2 hours or overnight.
6. Preheat the Oven: If roasting, preheat your oven to 400°F (200°C) during the last few minutes of marination.
7. Roast the Sprouts: Spread the marinated sprouts on a baking sheet in a single layer. Roast for 20-25 minutes, stirring halfway through until they become tender and caramelized.
8. Serve: Transfer the roasted Brussels sprouts to a serving platter, and if desired, sprinkle with toppings like toasted nuts, Parmesan cheese, or fresh herbs.
