The recipe for Keto Rosemary Garlic Roasted Radishes

Looking for an easy, keto-friendly substitute for oven-roasted potatoes? This recipe fits the bill! You can get these radishes in the oven in about 5 minutes, then do other things while they bake. The result is tender creamy roasted radishes with a hint of garlic and rosemary. There are even crispy browned bits on the edges–yum!

This recipe is based on the way I used to make roasted red potatoes. In fact, it’s the same exact recipe, except I used radishes instead of potatoes. The best thing is that these radishes are low-carb and they taste every bit as good as their high carb counterpart.

Why roast radishes?

I’m not going to lie. Before I ate low-carb, I had never eaten a cooked radish. I thought of them as something that we could only eat raw. Boy, was I wrong!

Cooking radishes softens the radish and gives them a more potato-like texture. In addition to softening the texture, the heat also softens the flavor. For example, the heat takes out the sharpness and leaves milder notes in its place. In fact, cooked radishes taste more like flavorful potatoes than they taste like raw radishes.

My first experience with cooking radishes was in one of our earlier recipes where I used daikon radishes to make home fries. I need to go back into that post and add nutritional information. Not to mention, the photos could use an upgrade! Even so, I remember devouring my trial runs of this recipe.

It actually took me a while to try roasting radishes. Now that I have, I’m excited to try using these gorgeous veggies in other ways. I have visions of using them in soups and stews and cooking them along side of roasts.

What goes well with keto-friendly Rosemary Garlic Roasted Radishes?

These radishes pair well anywhere you would normally serve roasted potatoes. They work well with a good steak, roasted chicken, or even roasted pork.

These little taste bombs can go with almost any simple main course. You can even swap out the rosemary for other herbs to make these roasted radishes pair better with the meat on the plate. For example, you could serve them with our salmon cakes, and leave out the rosemary, or swap it out for a bit of dill.

Other Keto-Friendly Potato Substitutes

While these keto-friendly Rosemary Garlic Roasted Radishes make a great substitute for roasted potatoes, my spud-addicted friends may want more ideas.

We have found cauliflower makes a great stand in for potatoes. In fact, it’s one of my favorites. I’ve used it in my low-carb “potato” soup, my mashed cauliflower with mushroom gravy recipe and my mashed cauliflower with smoked gouda. Both of these make excellent substitutes for mashed potatoes.

Celeriac makes another simple low carb substitute for potatoes. This veggie, also called celery root, might be the ugliest veggie in the produce department, but it’s also one of the most flavorful. It’s a bit higher in carbs than my friend, cauliflower, but I simply use it in smaller amounts. I’ve used celeriac in my Low-Carb Slow-Cooker Vegetable Beef Soup, and my keto-friendly Cottage Pie. Celeriac has a similar consistency to that of potatoes. In fact, It even tastes like potatoes. The only difference is that celeriac has a light note of celery.

Jicama also can be used as a potato substitute. One example of this is how Isabel from Isabel Eats uses jicama in her recipe for keto-friendly fries. Another way to use jicama is in these keto-friendly chips from The Happy Health Freak.
