Roasted radishes are an easy side dish! When you roast them their peppery bite is tone-down and their natural sweetness emerges. Pair them with purple onions for a delicious and beautiful side dish.

As a self-proclaimed roasting addict, I sat up straighter in my chair with wide-eyed wonder when I clicked on this article from The Kitchn espousing the virtues of roasted radishes.
When roasted at high temperatures, the radish’s bright poppy red skin turns a wonderful pastel pink, its crispness gives way to a juicy tenderness and its trademark peppery bite is muted. I took the Kitchn’s recipe a step further and tossed my radishes with some aromatic herbes de Provence and roasted them with red onion. Altogether it’s a side dish with sweet, caramelized flavors that’s impressive enough for a roast or ham, but easy enough for a weeknight accompaniment to chicken or pork chops.

In other words, you’ll want to keep this recipe handy.

So glad I found someone else that roasts radishes, I have a duck salad that I do with them that is wonderful, really mellows them out and gives them a beautiful texture.
April says
That sounds delicious, Brian ๐

YES! I can’t remember where I heard about roasting radishes, but now we do it all the time…they end up kind of sweeter, don’t they? I like adding dill butter to mine…YUM! I’ll have to try your recipe with the onions!
April says
So, so good! I can’t believe I’ve gone this long without them ๐

I love this recipe! I’m such a fan of radishes. Last year, we were fortunate enough to have some just-picked white radishes outside Durango, CO. with French butter and coarse sea salt. I love the idea of roasting them! I pinned it, and can’t wait to try. Thanks!
April says
Thanks so much, Tamara! Radishes with butter and salt is such a classic combo ๐ I haven’t tried white ones – will have to look for them.
Valentina says
