Mediterranean Roasted Vegetables with Olive Oil

Roasted vegetables are one of the most honest recipes in the kitchen. Chop the ingredients, drizzle with olive oil, put in the oven — heat does the rest. But the result is different every time, because the quality of the olive oil directly reflects in the flavor.

This recipe is based on the findings of the PREDIMED study, which examined the effects of the Mediterranean diet on cardiovascular health: a Mediterranean diet rich in extra virgin olive oil reduces the risk of cardiovascular disease by 30% (NEJM, 2013).

Why Cook with Olive Oil?

Olive oil's smoke point is approximately 190–210°C — the ideal temperature range for roasted vegetables. According to data from the International Olive Council (IOC), extra virgin olive oil remains more stable at this temperature compared to other vegetable oils. It helps caramelize the vegetables while adding a layer of flavor.

Ingredients (serves 4)

• 1 medium zucchini, sliced into half-moons
• 1 red + 1 yellow bell pepper, roughly chopped
• 1 small eggplant, cubed
• 200 g cherry tomatoes
• 1 red onion, roughly chopped
• 4–5 tablespoons early harvest cold-pressed extra virgin olive oil
• 3–4 sprigs fresh rosemary and thyme
• 4 cloves garlic, unpeeled
• Coarse salt, black pepper
• To serve: an extra drizzle of fresh olive oil, fresh basil

Instructions

1. Preheat the oven to 220°C.
2. Spread all vegetables across a large baking tray — do not overlap, as this prevents caramelization.
3. Drizzle with olive oil, salt and black pepper, add fresh herbs and garlic.
4. Roast for 25–30 minutes, stirring once halfway through.
5. Remove when edges are caramelized. Add fresh olive oil and basil before serving.
