Keto Potato Salad

Keto Potato Salad

Spoiler alert: this keto potato salad recipe does not actually contain potatoes at all. Instead, it stars roasted radishes, which take on a potato-like quality and texture after spending some time in the oven.

This keto-friendly potato salad made with radishes is both fresh and simple. It’s a great meal-prep contender to assemble ahead for warm-weather picnics, potlucks and BBQ cookouts.

Craft a traditional potato salad side dish or amp things up with protein and quality fat add-ins like crispy bacon and hard-boiled eggs. Not to mention, a ketone-supporting boost from our signature Bulletproof Brain Octane C8 MCT Oil.

Not feeling our radish vibes? Opt for roasted veggie alternatives like celeriac (celery root) or kohlrabi when making your low-carb potato salad concoction. Or, you can always go the cauliflower potato salad route. For those following paleo, sweet potatoes will do just fine…
