I think radishes are so fun for a season-spanning dish! Back in the days 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. Now I don’t have room for radishes in my new garden, but I am happy to report that I did plant my garden over the weekend (with two cute helpers), and I’ll share a post soon about what I’m growing this year. 

It was probably the abundance of radishes when I planted them every year that enticed me to try this recipe for Roasted Radishes with Soy Sauce and Toasted Sesame Seed (nearly ten years ago!) and this recipe was long overdue for a photo makeover. And cooked radishes have become rather trendy since then, maybe because radishes have been discovered as a low-carb vegetable option.

Cooked radishes are much milder and sweeter than the spicy flavor they have when they’re raw, and if I had to describe what they taste like I’d say similar to turnips, but slightly different. I love raw radishes, but I also love this recipe for roasted radishes 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!

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 sauce (or 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 sauce (or soy/sesame oil mixture). Sprinkle with sliced green onions. Roast 5-7 minutes more. Sprinkle with sesame seeds and serve hot.

Roasted Radishes would be a fun side dish for something grilled like Grilled Chicken Kabobs with Asian Marinade or World’s Best Pork Chops for a low-carb meal.

Roasted Radishes with Soy Sauce and Sesame Seeds
(Makes about 4 servings, recipe only slightly adapted from Vegetables Every Day by Jack Bishop.)

20-25 medium radishes, washed, trimmed and cut into fourths or halves (same-size pieces)
1 1/2 T roasted peanut oil
1 1/2 T soy sauce (use gluten-free soy sauce if needed)
1 tsp. toasted sesame oil (completely optional, but it adds more sesame flavor if you like that)
2 green onions, sliced
2-3 tsp. black sesame seeds (or use regular white sesame seeds and toast for a minute or so in a hot dry pan)


Preheat oven to 425 F. Wash radishes, trim ends, and cut into halves or fourths to make same size pieces. 

Spray a large baking sheet with non-stick spray, put radishes on the baking sheet and brush all sides with the peanut oil, then arrange radishes cut side down for best browning. Roast the radishes about 20 minutes, stirring one or two times.

While radishes cook, slice the green onions, and measure the sesame seeds (and toast if needed). If you’re using the sesame oil, mix with the soy sauce in the same bowl you used for the peanut oil.

When radishes are tender and starting to brown, remove from oven, brush with soy sauce or soy-sesame oil mixture, and sprinkle with green onion slices. Put back in oven and roast about 5-7 minutes more.

Sprinkle cooked radishes with sesame seeds and serve hot. I think these might be good with a little Sriracha Rooster Sauce for those who like spicy Asian flavors.

  1. Oooh! I love roasted vegetables but haven’t tried roasted radishes yet. Now I will!

  2. I’ve only ever eaten radishes raw, but these roasted ones look so delicious, that I might just try them roasted!

  3. I have never ever eaten cooked radishes, but what a fabulous idea! Might go into the same category as fennel — I’m not crazy about it raw, but cooked is simply delicious. Will definitely bookmark this recipe.

  4. I have never roasted radishes before. I love other roasted veggies so I will have to give them a try. Thanks for the idea.

  5. Perfect! I have a fridge full of radishes (they’re so cheap here you can get a fat bunch of about 20 for $1 at my market) and while I love them raw, I was looking for other ways to serve them. Roasted sounds lovely, plus I love the addition of the toasted sesame seeds.

  6. Thanks for this recipe, Kalyn. Guess what, I also wrote about radishes for this week WHB. I have always loved the Italian word for them: ravanelli.

  7. Very pretty, Kalyn!

  8. Hi everyone,
    So fun seeing so many of my favorite cooks have stopped by while I was out exercising (I’ve been slipping, but I’m trying to get back on schedule!) I’m so glad people like the looks of this recipe, because I’m telling you, I just inhaled it when I made it. I’ll be making hit again for sure.

  9. Of course that should say “making it” not “making hit.”

  10. Oh wow! I have never had radishes in any form other than fresh but these look divine! I am a huge fan of roasted veg (cauliflower is a favourite) so chances are these are going to appear on my table sometime soon. Btw, thanks for the rhubarb recipe link-love on Blogher ๐Ÿ™‚

  11. our farmer’s markets are overrun with radishes, and I’m not a huge fan of them raw, but I will try this out. Interesting…I’ve never even heard of them cooked, other than diakon. I may be blogging about this after the market on saturday, if I can sneak something like this into my wife…

  12. I knew if I was patient someone would tell me that radishes can be cooked – and how to do it. I have another 12′ row that is all ready at once. I’ll let you know how we fared. It looks delicious; can’t wrap my mind around the flavour, though, so I’ll just have to make it myself!

  13. yum yum yummmm

    Question though – what about using sesame oil instead of peanut?

    Oh, I have a cookie recipe up today you might like.

  14. Wow…I’ve never thought of roasting radishes before, I can’t wait to try this. Thanks!

  15. This is the second recipe I’ve seen today that cooked a vegetable I never would have thought to cook! Great idea Kalyn!

  16. Jeanne, you’re very welcome for the link. I’m also a huge roasted veggie fan.

    Rachael and Katie, do try it. The flavor is completely different than the raw radishes. Very mellow, almost sweet.

    Blest, from what I know of Chinese cooking, Sesame oil isn’t meant for cooking, it’s to add flavor. I think it’s a low smoke point oil. Interesting that you would ask though because I made asparagus similar to this recipe and put a little sesame oil in with the soy sauce for the last 5 minutes of cooking. Haven’t posted it yet.

    Dani, I thnk most of us (including me) haven’t ever roasted radishes before!

    Sara, always fun to try something unexpected.

  17. Wish I had found your blog sooner! I had radishes out the wazoo this spring!

  18. I have got to try this. I like radishes but I’ve never had them cooked before. They look good, though, and what isn’t great roasted?

  19. smashing! I first tried cooking radishes for the recipe “Conchiglie tutto giardinio” in the second vegetarian epicure book by Anna Thomas. I do love that recipe–just about in season now, isn’t it? hmmm. . .

  20. As I pulled a bunch of lovely red radishes from my local Co-op’s produce section today, I thought to myself, am I going to do another salad or is there another way I can fix radishes? And here you’ve answered my question. Who knew??? Not me. This recipe sounds fabulous! Thank you for sharing.

  21. kalyn, this is such an excellent idea! Love it! I’ll try it out for sure.

  22. I LOVE that recipe. I’m a huge radish fan and have discovered late in the game how good they taste cooked (tops included). Marvelous pictures.

  23. Lbp, never too many radishes, that’s what I say! But then I love radishes more than most people I think.

    Glenna, I’m so glad I have my toaster oven so I can roast veggies all summer. Try them, you’ll like them.

    TCL, I have that cookbook by Anna Thomas. Her book is where I first learned about bechamel sauce! Have to check out that recipe.

    Christine, great. Hope you will like it. (Looking forward to seeing you soon!!)

    Anh, it was fun to read about the Asian preparations for radishes when I was looking for stuff to write this post.

    Sher, I was thinking about saving the tops, because I had quite a few, but I got distracted. I’ll try that next time. You’ll have to tell me how you cook them.

  24. Kalyn, I have never heard of roasting radishes!! It looks so delicious!

  25. I’ve never tried cooked radishes, but it looks and sounds very good. I know what I’ll buy at the farmers’ market tomorrow. Thanks for the recipe.

  26. These sound fantastic. I’d never heard of cooking radishes until a month or two ago when one of my blog readers gave me a link to a recipe for braised radishes. I waited until I had enough radishes in the garden to make them, harvested, cleaned, and trimmed them, then stuck them in the fridge until dinner and promptly forgot about them. They’re still languishing in there I’m embarrassed to admit.

    I was sure the radishes would take on a whole new flavor when cooked, and it sounds like I’m right. I’m saving this to and am now inspired to plant a whole new crop and try to actually get it to the table this time!

  27. Patricia, they’re really good. Not as spicy tasting as I expected, but quite delicious.

    Burcu, hope you have fun trying them.

    Farmgirl, braised radishes sound divine also. Maybe with some kind of creamy sauce? Do plant more and try this, it’s really quite unique but delicious.

  28. I love radishes and am always looking for new ways to use them – they just scream at me from the market stall they’re so beautiful. Such a creative recipe!

  29. Kalyn,

    I had no idea that people cooked radishes ๐Ÿ™‚ Radishes are one of those things that I always thought I hated (don’t know where I got that idea) and then just discovered this year that I really enjoy them in salads! Now I’ll try them roasted! Thanks for including links to other radish recipes, too!

  30. Oy, I can’t believe how good these sound! Why oh why did I forget to buy radishes yesterday at farmers’ market?? I really have to try roasting radishes. Wow.

  31. Hi Kalyn,

    Looks like my first message did not get to you??? Anyway, you should know that it turned out delicious! I also used some kohlrabi as I did not have enough radishes for two :), topped with garlic and cilantro – just great!
    My husband loved it and the best part yet is that this morning I was over a pound less than yesterday… always dine like a pauper ๐Ÿ™‚

  32. Vanessa, thanks. I did love them like this.

    Nicole, the idea of cooking them is relatively new to me too, but I’m glad I did. I’ll definitely try them cooked in other recipes too.

    Lisa, get some next week and try this. I know you’ll like it.

    Ouizer, not sure what happened with your other message, but I’m so glad to hear you liked them. I LOVE the idea of using kohlrabi. That’s one of the vegetables I love but rarely see in the store.

  33. I didn’t have all of the ingredients in your recipe, so I just brushed the radishes with sesame oil, and added some sea salt and pepper, and roasted them alongside the salmon I had in the oven.

    Oh wow! They taste just like potatoes! What a great substitute when the craving hits! I’ll definitely do this again; thanks for the recipe!

  34. Elke, sounds like a great improvisation of the recipe. That’s the best way to cook. Thanks for letting us know that worked for other who might want to try it your way. Weren’t you surprised how mild tasting they were? I was.

  35. I am SERIOUSLY drooling here. This looks so incredible I’m going to have to go out and buy some radishes this weekend. In fact, I think I’ll print this page as soon as I’m done posting this comment.

  36. Oh, these were so good. I linked to your blog from mine when I posted about this recipe. Hope you don’t mind!

  37. Heather, hope you like them! Let me know how yours turn out.

    Rachael, thanks for the link. I’m glad you liked them and it’s fun seeing how other people make their own variation of the recipe, since I always do that too!

  38. Hey, I finally got around to trying these yesterday and they were delicious! Thanks! (Much better than my attempt to steam radishes)

  39. PastaQueen, so glad you liked them. See you soon at Blogher!

  40. Looks delicious. I’m going to have to give it a try. I just purchased some radishes at our farmer’s market earlier today.

  41. thanks for this. i really only ever toss in salads and salsa. can’t wait to try these.

  42. WOW Those look great!

  43. I never would have dreamed of roasting radishes, but I made this with daikon and it was wonderful! Here’s my version:

  44. I just wanted to report that I've never been a huge radish fan until now. These are awesome!

  45. Christa, glad you liked them!

  46. This recipe sounded odd, but it was delicious! I like radishes, but they are a little too hot, but these were great.


  47. Glad you liked it. I was surprised how good cooked radishes were too!

  48. I had white icicle radishes. Made this recipe…it was simply amazing!!!! Thank you!

  49. Wendy, glad you liked it!

  50. I made these tonight and they were terrific! Thank you!

  51. Oh good, so glad you enjoyed them.

  52. I made these for dinner tonight as a side with a grilled portobello mushroom cap that I marinated in soy sauce. Great combo. I have never been a big fan of radishes but these were great and I will definately try them again!

  53. Janice, that does sound like a good combination. So glad you liked the radishes.

  54. Roasting them as I type. They are almost done and just took a bite to taste – YUM! So glad to have a recipe for all the radishes in my garden! –too many to eat raw!

  55. Ann, that's exactly how I ended up trying this recipe. So glad you like it!

  56. Just became a member of a CSA and got a package of white radishes and red radishes. Tried this recipe and it was amazing! Ate all the radishes we got in one night. ๐Ÿ™ Now I need to go buy more to do it again!

  57. Roasted Radishes with Soy Sauce are the best way I have ever had radishes. I used to braise them but from now on will always roast them. Thank you for sharing the recipe.

  58. So glad you enjoyed the roasted radishes.

  59. We've always eaten radishes raw but tried your recipe for Christmas dinner. It was successful and we'll be roasting radishes again. Thank you for teaching us something new.

  60. Jennifer, so glad you enjoyed it.

  61. I keep seeing roasted radishes and still have not tried them. I need to make these and finally give it a go ๐Ÿ™‚

  62. I love Daikon radishes in salads. Has anyone tried this recipe with Daikons?

  63. 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.
