Made with just radishes and a handful of spices, these air fryer radishes are the perfect, poppable snack or low-carb side dish for dinner. This recipe has become a favorite in my home because it tastes similar to roasted potatoes! They require very little prep work and cook in just 12 minutes.

If you’re anything like me, you have a half-eaten bag of radishes in the bottom of your produce drawer. You might have already put them on a radish salad and made pickled radishes, so what else is there to make?
Well, this is the radish recipe to end all radish recipes. Crispy, low carb air fryer radishes, perfect for using up the last of your bunch! When roasted, radishes take on a similar taste and texture to roasted red potatoes.

Your new go-to side dish
- Radishes are low in carbs, actually insanely low, and mostly made of water. So, these air fryer radishes make a great alternative to roasted potatoes (they taste like roasted potatoes).
- There’s very little chopping involved, you just need to cut them in half.
- Totally vegan thanks to nutritional yeast bringing cheesy and umami flavors alongside staples like salt, pepper, and garlic powder.

Here’s what you’ll need
This is just an overview. Jump to the recipe card for the full measurements.
- Radishes: I like to buy either radishes from the farmers market with stalks and all or ones already washed and cut.
- Oil & Spice: And everything nice like olive oil or avocado oil, salt, black pepper, and garlic powder. Feel free to get creative and add in some red pepper flakes, cayenne, cajun seasoning, taco seasoning, or fresh herbs like parsley.
- Nutritional Yeast: This can be found in the baking aisle of the grocery store next to things like almond flour or coconut sugar. If you’re not vegan, you could use parmesan cheese in place of this.

turnips vs. radishes vs. potatoes
All of these are root vegetables with varying nutritional profiles. Radishes are the lowest in carbs and cook very quickly, while turnips are slightly higher in carbs. Both are great alternatives to the more starch-heavy potato.

Why this Recipe Works
I know I mentioned radishes have a high water content. This can also make it difficult to make crispy radishes because all the steam escaping tends to soften the vegetable. To avoid this, I did a few things.
- Air fry: I know this seems like a no-brainer, but air fryers work by shooting hot air all around the food. This constant circulation helps to dry out the radishes better than a traditional oven.
- Keep the slices in one layer: You might need to work in batches, but keeping the radishes in a single layer in the air fryer basket gives the hot air room to move, creating crispy edges.

FAVORITE AIR FRYER
After trying out a bunch of different air fryers, this is my favorite!

Serve it with
These can be eaten alone as a snack or paired with just about anything! Here are a few of my favorite combos.
- Sheet Pan Eggs and potatoes are a classic, so why not swap the potatoes for air fryer radishes?
- Crispy Baked Tofu “Chicken” Nuggets paired with air fryer radishes is like the ultimate adult lunchable!
- Vegetarian Meatloaf is a classic recipe that deserves a classic side – like roasted radishes! Ok, maybe they don’t seem classic, but beef and potatoes are, so let’s make vegetarian beef and radishes a classic.
- Vegetarian Caesar Salad can be paired with roasted radishes because there is nothing better than a refreshing salad with a crispy and salty side.
If you want another low-carb vegetable, you can try my air fryer carrot fries!
