Oven Roasted Radishes with Garlic

Jump to Recipe



Who knew that you could make delicious oven roasted radishes!? It wasn’t until I switched to a keto diet that I discovered the genius of oven baked radishes. Before going low carb, I had only had radishes sliced on top of tacos or fresh in a simple salad with sour cream. These roasted radishes are the perfect side dish for any meal including special occasions like Thanksgiving or Christmas. They have a mild flavor and are a great replacement for potatoes if following a low carb or keto diet. 

Why You Should Roast Radishes

  1. Cooking radishes mellows their earthy flavor. Radishes are a root vegetable that have a slightly peppery and earthy flavor. When baked, the flavor becomes more mild, making them easier to eat in the bulk. 
  2. They are low in carbohydrates. That’s right, radishes are perfect for a keto or low carb diet because they only contain about 1.8g of net carbs per 100g!
  3. Radishes are high in potassium. It’s important to keep up with electrolytes while following the keto diet. Doing so can help lessen symptoms of the dreaded “keto flu” when first starting out.

  4. Oven roasted radishes are delicious! Something magical happens when you roast radishes. They become tender and slightly crunchy with a delicious mild flavor that’s close to the taste of a turnip. They are a great replacement for roasted baby potatoes if following a low carb or keto diet. You can flavor the radishes however you like but they are great with a bit of garlic and some oil.
  5. It’s easy! Seriously, with only 5 minutes prep this is the easiest recipe to prepare on busy weeknights or those big family dinners when you are already cooking a million things. This is a great addition to any meal.
