Preheat oven to 400°F/200°C. Brush a baking dish or rimmed tray with olive oil. *
Add radishes to prepared baking dish, drizzle with olive oil and season with salt and freshly ground black pepper to taste. Roast for 45 minutes, until golden and crisp, tossing them about half way through.
Serve right away with generous pesto to dip. Or alternatively, toss the roasted radish wedges with the pesto until fully coated.
*Based on your feedback, some of you are roasting them at 450°F/230°C for 45-60 minutes. So you will need to do some fiddling around depending on the size of your radishes and oven. So we suggest you taste them a bit along the way and adjust accordingly. Just note that we do prefer to roast them for longer at a lower temperature for optimal results. Please note that nutrition facts are estimated for a 25g serving of raw radishes (about 4-5 medium radishes). And keep in mind that radishes shrink a lot when roasted.
