Start by preheating your oven to 425°F (220°C). This high temperature helps caramelize the vegetables and brings out their natural sweetness.
Cut all your vegetables into similar-sized pieces so they cook evenly. Place them in a large mixing bowl and get ready for the marinade.
In a small bowl or mason jar, combine olive oil, minced garlic, lemon juice, oregano, thyme, za’atar (or sumac), salt, and pepper. Stir or shake well to combine.
Pour the marinade over the vegetables and toss until everything is coated evenly. Make sure every piece is well-seasoned.
Spread the vegetables on a baking sheet in a single layer. Avoid overcrowding to allow them to roast properly.
Place the baking sheet in the oven and roast for 30–35 minutes. Stir halfway through for even cooking. The vegetables should be tender and slightly charred at the edges.
Once roasted, sprinkle fresh chopped herbs over the top. Serve warm and enjoy the burst of Mediterranean flavors.
