Baked radicchio with balsamic and olive oil is a warm, bittersweet vegetarian side. This fresh mediterranean dish is healthy, antioxidant-rich, and a family-friendly clean eats option.
Preheat oven to 400°F (200°C) and line a baking sheet with parchment.
Remove any damaged outer leaves from the radicchio, trim the stem, and cut each head into 4 wedges, keeping the core intact.
Place the radicchio wedges on the prepared baking sheet, drizzle evenly with olive oil and balsamic vinegar, and season with salt and black pepper.
Roast in the oven for 18–22 minutes, turning halfway through, until the centers are just tender and the edges show light browning.
Remove from oven, transfer to a serving platter, and sprinkle with freshly grated Parmesan while still warm. Serve immediately.
