Preparing Mediterranean roasted vegetables is a straightforward process that yields incredible results. Follow these steps to achieve the perfect roast:

1. Preheat the Oven: Start by preheating your oven to 425°F (220°C). This high temperature ensures that the vegetables roast evenly and develop a beautiful caramelization.
2. Prepare the Vegetables: Wash and dry all your vegetables thoroughly. Slice the bell peppers into strips, the zucchini into half-moons, and the eggplant into cubes. Cut the red onion into wedges and halve the cherry tomatoes.
3. Mix the Vegetables: In a large mixing bowl, combine all the prepared vegetables. Add the minced garlic to the bowl.
4. Season the Vegetables: Drizzle the olive oil over the vegetables, ensuring they are evenly coated. Sprinkle the dried oregano, thyme, rosemary, salt, and pepper over the mixture. If you’re using balsamic vinegar, add it now. Toss everything together until the vegetables are well coated with the seasonings.
5. Arrange on a Baking Sheet: Spread the seasoned vegetables in a single layer on a large baking sheet. Make sure they are not overcrowded, as this can lead to steaming rather than roasting.
6. Roast the Vegetables: Place the baking sheet in the preheated oven and roast for 25-30 minutes. Halfway through, stir the vegetables to ensure even cooking. The vegetables are ready when they are tender and slightly charred at the edges.
7. Garnish and Serve: Once roasted, remove the vegetables from the oven and transfer them to a serving platter. Garnish with fresh basil leaves for a burst of color and flavor.

By following these steps, you’ll create a dish that is not only visually appealing but also rich in flavor and nutrition.
