Recipe Notes

*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).
