If you don’t love raw radishes, this 5-ingredient recipe for Roasted Radishes and Onions recipe will definitely change your mind!
Roasted Radishes
This roasted radishes recipe couldn’t be simpler. It only has five ingredients, after all – three of which are pantry staples. I also tried them with shallots in place of onions and they were lovely. If you’d like to get fancy, feel free to season the radishes and onions with dried herbs like rosemary or thyme. See more side dish recipes here!
Believe it or not, this was my first time trying roasted radishes, and I was a big fan! Funny, Madison loves raw radishes with salt which always shocks me as that is not typical kid food. But I personally never cared for them.
So when I get my friend Rebecca’s cookbook The Ultimate Guide to Vegetable Side Dishes (affil link) and saw this recipe I was so curious.
Rebecca says “Radishes can be polarizing, but I’m on a mission to make everyone love them – these Roasted Radishes and Onions are just the way to do it. They are tender, crisp-on-the-outside, sweet, and mild – yes, mild! Roasted radishes are so sublime; they’ll convert even the biggest radish hater.”
She’s right, I’ve been converted! Radishes are a also a great low-carb, keto vegetable, so this side is perfect if you’re watching your carbs. See all of my keto recipes here.

- Buffalo Cauliflower “Wing” Bites
- Pepper Jack Corn Fritters

What are the benefits of eating radishes?
Radishes, a root vegetable, are low in carbs and calories and have no fat. A half- cup serving has just 19 calories and four grams of carbohydrates, plus one gram of fiber, making them good for digestive health. Radishes are also a good source of vitamin C, which helps boost immunity.
Do you peel radishes before cooking?
No, you do not need to peel radishes before cooking them. Just wash them and trim off the green tops.
How to Roast Radishes in the Oven
Roasting radishes can be done in three easy steps.
1. Put the radishes and onions on a rimmed baking sheet or cast iron skillet.
2. Drizzle olive oil over them and sprinkle with salt and pepper.
3. Roast for 30-40 minutes at 350 degrees, stirring every ten minutes.
What to Serve with Roasted Radishes
To turn roasted radishes into a low-carb dinner, serve them with roasted chicken, roast beef, or turkey with a salad on the side. If you’d like a side dish with carbs, my Smashed Sweet Potatoes, Rice Pilaf, or Instant Pot Mashed Potatoes would be delicious with these radishes.
