Tips for Perfect Roasted Radishes

  • Longer Roast for Better Texture: Radishes contain more water than potatoes, so they need a longer roasting time to achieve that desirable crispiness.

  • Pairing Ideas: These roasted radishes pair wonderfully with roasted meats, grilled fish, or even as a base for a loaded keto dish topped with bacon, cheese, and sour cream.

Best Keto Roasted Potatoes (Low Carb Radishes Recipe)

Prep Time: 5 minutes
Cook Time: 15 minutes
Total Time: 20 minutes

These Keto Roasted Radishes are an extraordinary low-carb alternative that perfectly mimics the texture and flavor of potatoes.


  • 1 pound of Radishes
  • 2 Tablespoons of Olive Oil
  • 1 Teaspoon of Garlic Powder
  • 1/2 Teaspoon of Onion Powder
  • 1/4 Teaspoon of Parsley
  • 1/2 Teaspoon of Basil
  • 1/2 Teaspoon of Cayenne Pepper
  • 1/2 Teaspoon of Sea Salt
  • 1/4 Teaspoon of Black Pepper
  • Pinch of Rosemary


Preheat your oven to 425 degrees. Prepare red radishes for cooking by cutting and cleaning them. Chop off the radish greens, stems, and ends. Roughly chop the radishes into bite-sized pieces.

In a small mixing bowl, add the seasonings such as onion powder, garlic powder, sea salt, and black pepper. You can use fresh herbs if you prefer or stick with the easy prepackaged kind.

Add the fresh radishes to a large bowl and coat them with olive oil. Stirring to ensure good coverage.

Sprinkle the seasonings on top of the radishes and then stir well to ensure you have loaded radishes with an even coating.

Place radishes in a single layer on a baking sheet protected by aluminum foil.

Bake for a total of 15 minutes. Add more time if you prefer darker, roast radishes. You can get a similar result by cutting your bunches of radishes into very small pieces.


The smaller the pieces the faster these oven-roasted radishes will begin to brown and come to a crisp. Cook longer for extra crispy potato like radishes.

I don’t use radishes much, but they always look so inviting when I see them at the farmers market. Will definitely try this with some fresh local radishes!
