Radishes Make the Best Low Carb Keto Potato Salad Substitute (Nutrition Breakdown of Potatoes vs. Radishes)

I can’t remember the last time I made a “potato salad” with actual white potatoes. Fortunately, I know the perfect, low-carb substitute, while still delivering on that crisp texture that I look for in my salads.

Keto Potato Salad

Radishes are a great keto-approved alternative and are full of nutrients that we all need for healthy body function–a win-win.

Compared to white potatoes, radishes also have 2.78 times more calcium, which is important for bone health, and 38.89% more folate which promotes proper brain function. (1)

Radishes contain only 16 calories per 100 grams vs. white potatoes at 77 calories per 100 grams. (2) They contain 16.78% more water per serving, which is partly how it still has that yummy bite to it without containing too many carbs.

Which Radishes Are Best for Keto Potato Salad? (4 Best Types of Radishes to Use)

There are many different types of radish ranging from mild to spicy, and bland to sweet. Personally, my favorites are either the round radishes or Daikon radishes but feel free to try these other varieties as well:

  • Daikon radishes – Daikon radishes or Chinese white radishes, are one of the most popular varieties of radish and are readily available in most supermarkets. These are of large variety, long, and white in color.
  • Round radishes – Round radishes are another common type of radish and may be red, purple or white in color.
  • Watermelon radishes – Watermelon radishes are beautiful additions to any potato salad because of its unique coloring. It is greenish or beige on the outside and a muted magenta on the inside, hence its name. It’s also milder in flavor compared to round radishes.
  • White icicle radishes – White icicle radishes are milder in flavor and hold their crisp texture well. They are known for their snow-white color and elongated shape.

A note on horseradishes: Although horseradishes are another variety of radish, they are quite pungent and known for their spicy flavor, so they’re not ideal for potato salad recipes.

How to Make Creamy Dill Keto Potato Salad

This “potato” salad is very easy to make and requires minimal cooking, so it can be ready in almost no time at all.

  • Boil the radishes. If you are using larger radishes, be sure to peel the skin off first. For smaller radishes with thinner outer skin, you may opt to leave the skin on before boiling.
  • Combine the wet ingredients in a large bowl. Using a spoon, mix together the mayonnaise, mustard, dill and lemon juice. No need for a mixer or whisk for this.
  • Add the rest of the ingredients. Add in your boiled and drained radishes, eggs, celery and onion.
  • Toss and serve. Once seasoned to your liking, it’s ready!

Alternative Low Carb Veggies to Use for Keto-friendly Potato Salad

Each ~130 gram serving of this recipe contains about 4 grams of carbs from the radish alone. That’s impressive considering the volume of the serving and how filling it actually is!

Radish – 31.7 grams of carbs for the whole recipe (8 servings). 3.9 g per serving.

And even though that’s hard to top, I have a few other low-carb veggies that would also be great for making keto-friendly potato salad:

Jicama (Mexican turnip) – 79.8 grams of carbs for the whole recipe (8 servings). 9.9g per serving.

Zucchini – 28.1 grams of carbs for the whole recipe (8 servings). 3.5g per serving.

Cucumber – 32.7 grams of carbs for the whole recipe (8 servings). 4.1g per serving.

How Long Will Radish Salad Keep in the Fridge?

This radish salad will keep for about 3-5 days in the fridge. There may be some discoloration with the mayonnaise, but that’s normal and not something you should be alarmed about.

However, I don’t recommend storing it in the fridge for too long as it’s best eaten fresh.
