Radishes are the perfect alternative to potatoes and if you're keeping your carbs low, then this recipe is just what you need. These air fryer radishes are not just low in carbs, they are dairy-free and low in calories too. One serving contains less than 4 grams of net carbs and 100 calories!

They are flavored with ranch seasoning and then cooked until crispy in an Air Fryer. Serve with roast chicken, salmon, pork chops or sprinkled with some hard cheese or crumbled feta for an easy keto vegetarian meal.

Oven Baking Instructions

If you don't have an Air Fryer, you can simply bake the radishes in the oven. To do that, place the radishes in a tray lined with parchment paper, drizzle with oil and toss, and bake at 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional) for 20-25 minutes, rotating the tray and tossing halfway.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

This recipe looks lovely.  I wanted to print it, but really don’t need/want to print 4 pages full of colour pictures.  Would it be possible to just print the ingredients and instructions?  That would be great and so helpful.

Hi Christiana, I think you may be viewing this from the our app? If you only want one page, you can click the print button on our website (for a short version with no photos). We are planning to do this in the app too - it is somewhere in the long list of features 😊

Brilliant, thank you!
