Oven Roasted Keto Radishes:

Can you eat potatoes on a low carb keto diet? Well, you could. But chances are eating more than a few bites would eventually lead to throwing you out of a state of ketosis.

Remember, keto is a metabolic state… not a food!

That being said, many people who are following a ketogenic way of eating are most likely not looking to use their days allotment of carbs on a potato (but if you do, I’m here for that too). In comes the keto fauxtato, aka radishes.

Do you ever eat radishes? Raw radishes are great as a low carb chip option (love these with Guacamole or on my Loaded Keto Nachos with Bacon Chips) or even just for snacking. They are peppery, a bit spicy, and have a great crunch too!

But a roasted radish is low carb gold my potato loving friends. As a girl who grew up on meat and potatoes, I can honestly say I love these a low carb option. The carb count is generally low bringing the total net carbs for a serving to 3 which is much lower than a standard baked potato for instance (complete nutritional information can be found below the recipe).

Follow the recipe for these easy cooked radishes below and read through this blog post for all the helpful cooking tips and tricks for making the perfect roasted and smashed radish recipe!

“Class” Notes:

Are Radishes Keto Friendly?

Yes! Radishes are a keto friendly low carb vegetable that contain very little calories and a lot of fiber and other nutrients. According to an article about radishes on Healthline, red radishes are a great source of B vitamins, vitamin k, potassium, calcium and more!

The best way to eat radishes on a keto diet are to eat them raw and sliced thin (like I mentioned above). However, the best way to approach a keto radish recipe is to treat them just like a potato (but have a little more patience).

I promise these are worth the wait, make an incredible keto side dish that can help you stay low carb or keto during the holidays too. Even the non-keto eaters are going to want to get in on this!

How To Make Oven Roasted Keto Smashed Radishes-

Start by boiling the radishes in a large pot of water. Depending on the size of your radishes, you may want to half them length wise. I tried to keep mine all even in size as possible and only had to really chop a few!

Because the texture is a lot more dense than a regular potato, I did find that they took a while to boil. As long as you plan ahead a bit here, you will be just fine (it’s hands off and easy) with getting these on the table and in the mouths of your loved ones in no time!

Please note that boiled radishes also look, well strange. The water turns a dark purple because of the color of the radishes, but don’t stress! This is normal! Check the boiled radishes for tenderness with a for. You want the fork to easily slide into the radish (this is crucial to the smashing process).

How To Brown Radishes In The Oven-

Drain the water from the pot and place the cooked radishes onto a paper towel to remove some of the excess water (this helps with browning and crisping the radishes so they become more like oven fried radishes in texture).

Preheat your oven to 425 F and prep a baking sheet or baking dish with parchment paper to prevent sticking. Prep the tender radishes by spacing them out across the baking sheet. You can use a potato masher or just simply a fork to smash them and flatten them slightly on the baking sheet. I smash both lengthwise and then crosswise.

Season the radishes at this point with salt and pepper. I like a fine drizzle of olive oil and then maybe fresh herbs like thyme or rosemary too. Bake them off for a bit to help start the browning process. About halfway into baking remove them and add some fresh grated Parmesan cheese.

Parmesan roasted radishes

Because Parmesan roasted radishes are far superior to just regular roasted radishes. We love our cheese here in the Bon Appeteach household and we are not afraid to show it! Let the radishes continue to bake until the edges start to brown and the cheese gets bubbly.

At this point, your roasted radishes are smashed, browned, and ready to serve! Sometimes if I want a little more color, I’ll even throw them under the broiler for a minute or so to get some nice color on them.

Oven Roasted Keto Radishes- "Smashed" Radish Recipe

Miss potatoes on a low carb keto diet? This is the perfect keto fauxtato recipe modeled after smashed roast potatoes. It makes this low carb side dish perfect for dinner or any healthy meal plan!

Prep Time 5 minutes
Cook Time 45 minutes
Total Time 50 minutes


  • 2 Bags (16 oz). Red Radishes
  • Olive Oil
  • Salt & Pepper
  • Fresh Herbs (I like Thyme or Rosemary)
  • 1/2 cup Fresh Grated Parmesan Cheese


  1. Rinse the radishes to remove any excess dirt. Look at the size of the radishes and slice in half lengthwise if you have very large radishes. I leave the smaller one's whole. Try to make them equal in size for an even baking time.
  2. Preheat the oven to 425 F and place the radishes onto a baking sheet and roast them for 30-40 minutes until tender (I test them with a fork, if the fork easily pierces the skin like a baked potato they are good to go). Remove from the oven and using a fork or potato masher to smash the radishes so they are flat and even.
  3. Drizzle with a little olive oil, season with salt and pepper, add some fresh herbs if desired (I used fresh thyme or rosemary), and the Parmesan cheese and bake like this for another 10-15 minutes.The cheese should melt and the edges of the radishes should lightly brown.
  4. If you desire more browning, pop them under the broiled for a minute or so (but watch it so it doesn't burn) and then remove to serve.
