Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F). Gather all your vegetables and slice the eggplant, zucchini, bell peppers, and onion into roughly 1/4 inch thick slices or strips. Mince the garlic and set aside.
- In a large mixing bowl, toss the sliced vegetables and cherry tomatoes with 2 tablespoons of olive oil, minced garlic, salt, pepper, and dried herbs. Make sure everything is evenly coated—that’s the key to flavorful roasting.
- Spread the seasoned vegetables in a single layer on a large rimmed baking sheet. Arrange them so they aren’t overlapping too much, giving each piece room to caramelize.
- Place the sheet in the oven and roast for about 25-30 minutes. Halfway through, use a spatula or tongs to turn the vegetables gently, ensuring even browning and caramelization. The vegetables will start to soften, brown around the edges, and smell fragrant and smoky.
- Once the vegetables are tender, caramelized, and fragrant, remove the sheet from the oven. Let them sit for a few minutes to cool slightly, which helps the flavors settle.
- Garnish with freshly chopped basil or parsley for a bright, herbal finish. Serve hot, perhaps with crusty bread or over grains for a hearty meal.
