Why You Should Be Roasting Your Radishes

I’m always surprised when I hear that people aren’t eating radishes very often, or that they’re never tried them! These crunchy, pepper, vibrant root vegetables are incredibly versatile and packed with a ton of healthy nutrients. Radishes are rich in antioxidants and minerals like calcium and potassium, which help lower high blood pressure and reduce risks for heart disease. They’re also a good source of natural nitrates that improve blood flow. As a nutritionist, I’m always looking for ways to get more colorful, nutrient-dense sides in rotation.

While they’re often served raw on salads or as crudités, they’re also super succulent with a crispy exterior when roasted at a high temperature and seasoned in simple flavors. This makes a side dish that’s a great accompaniment to nearly every meal, especially my Baked Greek Kofta Kebabs and my Grilled Picanha Steak!

While they’re available year-round, they’re in-season in the spring. But to be honest, I love preparing these bright purple beauties all year long!


This is one of those recipes you can memorize and whip out any day of the week or for any occasion! I like roasting my radishes in extra virgin olive oil, sea salt, and dried rosemary, then drizzling with some fresh-squeezed lemon juice before serving.

But you can customize this roasted radish recipe however you like! Any fresh or dried herbs pair well with radishes, especially thyme and dill. And if you’re not following the AIP diet, crack on some fresh black pepper. Perfection!

Don’t forget to wash your radishes thoroughly to remove any dirt and to trim the tops and bottoms! (These would be great additions to a compost pile.)

How To Make Roasted Radishes

This roasted radish recipe could not be more simple!

  • Just give your root veggies a good scrub, slice them in half, and place on a prepared baking dish.
  • Preheat your oven to 425, and toss your radishes in the extra virgin olive oil, sea salt, dried rosemary, and any other preferred seasonings.
  • Roast for 20-25 minutes at 425 degrees. Flip them halfway to prevent burning.
  • Serve warm as a simple, yet flavorful, side dish. That’s it!

Tips and Variations

  • Add some aromatics like minced garlic, shallot, or green onion for even more flavor.
  • Slice them in quarters instead of halves to make them more kid-friendly (for little hands and little mouths).
  • Add more of your favorite veggies like Brussels sprouts or potatoes to make this an even hardier side dish.

Save these easy roasted radishes a place at your holiday table! They’re a great addition to Christmas, Thanksgiving, or Easter menus.

What To Serve with Roasted radishes

Storage, Freezing, and Reheating Instructions

  • Store leftover radishes in an airtight container in your refrigerator for up to 4 days. 
  • Freeze cooked and cooled roasted radishes in an airtight, freezer-safe container or plastic bag for up to 1 month. (Full disclaimer: we did not freeze these simply because there were never any leftover! The texture may change a bit from the freezing-and-thawing process, so we recommend enjoying these fresh.)
  • Reheat by warming in the oven at 350 for 10 minutes or so until heated through and re-crisped. You could also reheat in the air fryer at 400 degrees for 5 minutes or so for a crispier option, or just in the microwave for 2 minutes or so.
