Spring and summer are some of the easiest times of year for low carb recipes. Between fresh grilled meats, juicy burgers (either bunless or on low carb hamburger buns), and simple salads (like a creamy cucumber salad for a side or a healthy taco salad as a meal), there are many delicious options to choose from. Best of all, many of these foods will please everyone – even if they are not eating low carb. Before I made this cauliflower potato salad recipe, I didn’t expect it to be one of those. To my surprise, it was!

The dressing is what really makes the dish — and just like the original version, this keto potato salad (sometimes called mock potato salad or faux potato salad) is perfect for barbecues, picnics, or family get-togethers.

Ingredients & Substitutions

This section explains how to choose the best ingredients for keto potato salad, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Cauliflower – The cauliflower taste in this dish is actually quite mild, and the texture of this low carb potato salad is very much like a regular one. The key is cooking the cauliflower to the same softness as cooked potatoes would be. To do this, make sure your florets are very small. This will allow them to cook up very soft.
Mayonnaise – I use homemade mayo, but you can use any kind of mayonnaise that you prefer. You could also use plain Greek yogurt or sour cream, but mayo creates the best flavor.
Apple Cider Vinegar – Apple cider vinegar adds a tart and zesty flavor to this keto cauliflower potato salad. You can substitute white vinegar or lemon juice if you like.
Dijon Mustard – I prefer the flavor of Dijon here, but regular yellow mustard would also work.
Seasoning – To add a delicious flavor to the keto potato salad dressing, you’ll need garlic powder, sea salt, paprika (or substitute smoked paprika), and black pepper.
Onion – While I selected a yellow onion for this recipe, a white onion, red onion, or sweet onion would work nicely as well. Dice it finely.
Celery – Finely diced. Other low carb vegetables like celeriac or fennel stalks would make good substitutes.
Eggs – My favorite method to boil them is these easy peel hard boiled eggs, but you could also make air fryer hard-boiled eggs.
Chives – Optional for garnish. You could also use fresh dill.

VARIATION: Add dill pickles or bacon!

If you like these flavors in potato salads, you’ll like them in this cauliflower potato salad, too. Just mince the pickles finely or crumble oven baked bacon, and add to your taste.

How To Make Cauliflower Potato Salad

This section shows how to make keto potato salad, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

Cook the cauliflower. Either in the microwave or the stove top, cook the cauliflower and drain well. (I cooked it in boiling water in a saucepan.) You could also use a steamer, or even use roasted cauliflower here if you like the flavor, like I do for roasted cauliflower salad.

TIP: Cook a double batch of cauliflower to use in other recipes.

Mashed cauliflower is another easy low carb dish that’s made from very soft cooked cauliflower like the kind for this recipe.

Make the dressing. In a small bowl, whisk together the mayonnaise, apple cider vinegar, Dijon mustard, garlic powder, paprika, sea salt, and black pepper, until smooth.

Combine. In a large mixing bowl or serving bowl, stir the cooked cauliflower, diced onion and celery, and hard boiled eggs together with the dressing. If desired, garnish with chives and additional paprika.

TIP: If you have time, refrigerate the cauliflower potato salad for 1 hour.

This is not requires, but will let the flavors develop more.

Storage Instructions

Store: This easy cauliflower potato salad can store in an airtight container in the fridge for up to 5 days. Freezing is not recommended, as mayo-based dressings like this one don’t freeze well.
Meal prep: Since this keto potato salad stores well, you can easily make it ahead of time. Alternatively, you can cook the cauliflower, chop the other vegetables, or make the dressing ahead.
