If you make one keto side dish this Summer, let it be Keto 'Potato' Salad! It’s more like a Faux-tato Salad than a regular potato salad because this low-carb recipe uses radishes in place of the potatoes. You can’t tell they are radishes, trust me! They taste like regular potatoes.

Radishes In Place Of Potatoes

Radishes are quickly becoming the keto dieter’s version of a potato. If you toss them in olive oil, salt and pepper and roast them in the oven, they taste like home fried potatoes. In this recipe, I use the same approach. The radishes were roasted at 350 degrees and cooled before adding them to the potato salad. If you are using purple radishes, the skin on the radish can cause the “potato” salad to turn a purple or pink color. To avoid this, peel the radishes before roasting or use a daikon radish. Cauliflower is also a popular potato replacement in low carb cooking. Instead of radish, you could opt to use lightly steamed chopped cauliflower in this recipe. Steam the cauliflower until barely soft, drain and cool before making cauliflower potato salad.
