Are Radishes Healthy?

Radishes are a popular root vegetable that’s so easy to grow. The low carb and keto craze has put this humble veggie center-stage and for good reason! Bright red and crunchy, with a slightly sweet-spicy flavor, radishes can be served hot or cold!

Even the greens can be chopped up and put into a salad! Or sauteed to make a delicious side. Or, added to a smoothie, like our blueberry banana smoothie!

And yes—packed with anti-oxidants, radishes are a low cal, low fat, low carb healthy vegetable superstar that are also a great source of vitamins B6, C, A, E, and K, as well as fiber, potassium, copper, iron, and magnesium.

Our Fave Radish Recipe

  • Prepped, seasoned, and made in minutes, roasted radishes are more than a side dish!
  • Serve them as an appetizer with some Easy Greek Yogurt Dip, Creamy Dill Dressing, or some yummy Tzatziki.
  • Try Watermelon radishes which are larger and softer than regular radishes. And they can be cut into wedges which makes for a striking dish!

What’s in Roasted Radishes?

RADISHES: Choose radishes that are heavy, with a firm skin, and are unblemished. This same recipe can be applied to other low-carb veggies like turnips, brussels sprouts, broccoli, or any other thick, low-carb vegetable.

OILS: Olive oil is a healthier, lighter option over other oils. But butter will work and even leftover bacon grease is still keto, but with a little more flavor!

SEASONINGS: Use pre-packaged Italian seasoning mix or try one of these two amazing recipes for Italian Dressing Mix or this Homemade Italian Dressing Recipe. Roast with cloves of garlic on the baking sheet and serve alongside. Garlic cloves become sweet and savory once they’ve been roasted and add a colorful and flavorful complement to the radishes.

How to Roast Radishes

Just two simple steps are all it takes to make this unusual and totally delish side dish!

  1. Prepare radishes and cut the larger ones in half. Toss radishes in oil and sprinkle on seasoning mix. 
  2. Place oiled and seasoned radishes on a baking sheet and roast per recipe below.

PRO TIP: Avoid baking too long so they stay firm, they will continue to cook once removed from the oven (carryover cooking). Serve immediately or with the dips/dressings listed above.

In the Instant Pot:

  1. Prepare radishes and cut the larger ones in half.
  2. Toss radishes in oil and sprinkle on seasoning mix. 
  3. Cook seasoned radishes in an Instant Pot sealed to high for 8 minutes.
  4. Allow the steam to naturally release.

How to Store

Keep cooled roasted radishes in an airtight container or zippered bag in the refrigerator up to 3 days. Reheat them in an oiled skillet or even an air fryer, until they are browned or blackened. Then just season and serve. Or, like me, eat them cold right out of the refrigerator. They’re a great snack (that I can’t resist)!

Freeze them in small bags with the date labeled on the outside. Once thawed, they will be soft but can be crisped up under the broiler.

    The Italian seasoning is a bit much for us. We prefer them with just S&P and EVOO. Roasted until soft and they taste just like a buttered mash potato, but healthier for you!
