Simple roasted radishes make a great, lighter alternative to potatoes. Easy to prep and bake – no peeling or par-boiling like potatoes.
I love to season them with a little salt, pepper and garlic powder, then toss in a little oil and baked until beautifully golden brown.

Sometimes I just get a bit potato-ed out. You know what I mean?

Now don’t get me wrong, I love my carbs. Pretty much all of my meals are served with rice, pasta, potatoes or bread!! Which is why i’ve always totally sucked at keto diets.
Give me 4 days on keto, and I’m a snarling grumpy something-or-other, who no-one wants to be around.


These roasted radishes are pretty keto friendly.
That is, if you don’t serve them up with mashed potato, like I have on one of my photos below 😁

πŸ“‹ What do we need?

  • Plenty of radishes. They shrink a little when roasted, so I use quite a lot – about 100g (just under 1/4 lb) per serving.
    • I use the round or cylindrical radishes – that are red/pink or purple in colour.
  • Oil – your favourite oil for baking is fine. I use olive oil.
  • Seasoning – just salt, pepper and a little garlic powder. You can use more spices if you prefer – such as paprika, chilli powder or even a little cumin or Cajun spices.

πŸ”ͺ How to roast radishes

Full recipe with detailed steps in the recipe card at the end of this post.

  1. Place halved radishes on a metal baking tray and toss with oil, salt, pepper and garlic powder.
  2. Bake in a hot oven (200c/400f) for about 30-35 minutes, until golden.
  3. That’s it, done. Super easy!!

You can serve them in place of potatoes, or as well as potatoes – as I have here in my creamy pork and apple casserole recipe.

Some of my favourite main dishes that work well with roasted radishes (apart from the casserole above) are:

Would you use them as a potato replacement? or serve them alongside potatoes?

I’d love to hear what you’d serve them with (let me know in the comments below).

    We tried these as a side dish to a beef casserole. Everyone agreed that they were a delicious change from our usual sides. Thank you for the ideaπŸ˜‹

    Hi Nicky!
    Do they lose their heat once they are roasted?
