Roasted Radishes
I have recently developed a newfound love for radishes. They are amazing sliced thinly and served with dips, or quickly pickled and tossed into salads, but I can’t believe it’s taken me until recently to discover how delicious they are roasted!

Roasted Radishes



After roasting, radishes lose their peppery flavour and become creamy on the inside with a crisp outer skin. Radishes have a very high water content (95% which is the same as celery), and they retain a lot of that moisture when cooked. If you aren’t a fan of the sharp flavour of raw radishes, you should still give these roasted radishes a try, they are slightly sweet and so juicy with a completely different flavour and texture profile then when eaten raw.



Roasted radishes couldn’t be any easier to make and can be prepared in just a few simple steps:

  1. Wash the radishes and trim the tops
  2. To ensure the radishes all cook in the same time, cut any larger sized radishes in half.
  3. Toss the radishes in olive oil and season with salt and pepper. 
  4. Place the radishes in a cast iron skillet or baking dishes and place in the oven to cook for 20-25 minutes. 
  5. Garnish with chopped parsley and enjoy!

These Roasted Radishes are a fantastic side dish to serve in place of roasted potatoes. Not only are they full of flavour, they are also very low in calories and carbohydrates. How low? Well 100 grams of new potatoes is 75 calories and 17 grams of carbohydrates, while the same weight in radishes is just 26 calories and 3.5 grams of carbs. If you are on a low carbohydrate diet such as the keto diet, roasted radishes are a great side dish. 



I made a big batch of these radishes to have with roast chicken for dinner and then tossed the leftover into a salad the following day for lunch.Here are a few more dishes that would be delicious with these baked radishes. 



Leftover Roasted Radishes can be stored in an airtight container for up to 4 days in the fridge. I recommend reheating them in a skillet with a splash of oil to make them slightly crisp on the edges.
