I think radishes are so fun for a season-spanning dish! When I had a huge garden, I always used to plant them just for the fun of watching how quickly the radishes came up from seeds. And it was probably the abundance of radishes when I planted them every year that enticed me to try this fun and tasty recipe for Roasted Radishes flavored with soy sauce and sesame seeds.
And cooked radishes have become trendy since then because radishes have been discovered as a low-carb vegetable option. When they’re cooked, radishes become much milder and sweeter than the spicy flavor that’s associated with raw radishes. If you asked me to describe what they taste like I’d say cooked radishes are similar to cooked turnips, but slightly different.
I love raw radishes, but I also love this roasted radishes recipe and if you’re looking for a side dish that will be a conversation-starter, I promise this will be something fun and unusual to serve your friends or family!

How to make this Roasted Radishes recipe:
(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)
- Wash radishes, trim ends, and cut into half or fourths (to get same-size pieces.)
- Put radishes on baking sheet and brush with peanut oil (or other oil if you can’t have peanuts.)
- While radishes roast, prepare the sliced green onion, soy/sesame glaze, and sesame seeds. (I used black sesame seeds, but if you use regular white ones I’d toast them for a minute or so in a hot dry pan.)
- The color of the radishes will fade a bit as they cook. After about 20 minutes remove the radishes from the oven and brush with the soy/sesame mixture. Sprinkle with sliced green onions.
- Roast 5-7 minutes more.
- Sprinkle with sesame seeds and serve hot.

Just tried this, it was absolutely scrumptious! I didn't have green onions, but used garden chives instead. I'm just so surprised at how different these radishes taste, love this recipe.
So glad you enjoyed it; love the idea of using chives! (Note to self, plant some chives!)
I love Daikon radishes in salads. Has anyone tried this recipe with Daikons?
I've made it with a mix of Daikon and red radishes and it was great!
I keep seeing roasted radishes and still have not tried them. I need to make these and finally give it a go 🙂
Nicole, they are fun and also very tasty!
Jennifer, so glad you enjoyed it.
