A bowlful of oven roasted radishes.

Oven Roasted Radishes are a delicious low carb and keto friendly side dish recipe that is super easy to make. Once roasted, the radish loses its “bite” and mellow out with a texture and flavor similar to that of a roasted potato.

Serve these oven roasted radishes as a side dish, or, as a substitute to potatoes in soups or stews. And are they excellent served hot with a side of sour cream and chive topping.

Radishes Are The New Potato

If you have been around me enough, you know that as a child I would not eat potatoes. I actually got caught tossing them in the trash one Thanksgiving. As I got older, I began to like them a little more, but always prefered them to be crispy on the outside and creamy on the inside.

These Oven Roasted Radishes are very similar to a potato when cooked, and I actually tend to like them better than potatoes!

Radishes have a natural “bite” to them, that some may call heat or spice. However, oven roasted radishes lose that bite and mellow out. Their texture is close to that of a potato and the flavor is very close.

What You Need To Make Oven Roasted Radishes

Umami Powder, this is my preferred brand.

Tips and Substitutions

  • Always wash and trim the radishes. I cut the root end off and make sure the top stalk is trimmed off as well. Once washed, pat the radishes dry.
  • Cut the bigger radishes in half or quarters and leave the smaller ones uncut. Tryin to keep the radishes all similar in size before oven roasting them.
  • Substitute the umami seasoning for 1 teaspoon salt, 1/2 teaspoon pepper, and 1/2 teaspoon smoked paprika.
  • Depending on the umami seasoning you use, you may need to add a little salt and pepper to the oven roasted radishes.
