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 flavored with soy sauce and sesame seeds. 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!

How to make this recipe:

(Scroll down for complete recipe with nutritional information.)

  1. Wash radishes, trim ends, and cut into half or fourths (to get same-size pieces.)
  2. Put radishes on baking sheet and brush with peanut oil (or other oil if you can’t have peanuts.)
  3. 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.)
  4. 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.
  5. Roast 5-7 minutes more.
  6. Sprinkle with sesame seeds and serve hot.

Make it a Meal

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.
