This Keto Cauliflower Potato Salad is a great twist on the classic! It uses cauliflower instead of potatoes, making it low in carbs yet deliciously creamy and filling.
It’s perfect for potlucks or picnics, and it’s so easy to whip up. I love adding a little crunch with celery—you can’t go wrong with a side that tastes great and is good for you!
Ingredients & Substitutions
Cauliflower: Cauliflower is the star here, giving a low-carb version of potato salad. Make sure to cut it into small florets for even cooking. If you miss the taste of potatoes, use half cauliflower and half potatoes for a blend.
Mayonnaise: Opt for sugar-free mayonnaise for a healthier touch. If you’re looking for a dairy-free option, avocado oil mayonnaise works great too!
Sour Cream: Traditional sour cream adds creaminess. If you’re avoiding dairy, substitute with vegan sour cream or even blended silken tofu for a lighter option. It’ll still taste wonderful!
Dill: Fresh dill brightens up the salad. If you can’t find it, use dried dill (but use less, as it’s more concentrated) or switch to fresh chives or parsley for a different herby twist.
Why is Cooking Cauliflower and Potatoes Just Right Important?
Getting the cooking time right for cauliflower (and potatoes, if using) is key to a good salad. If overcooked, they become mushy and won’t hold up well. Here’s how to ensure they’re perfect:
- Bring a large pot of salted water to a boil. The salt helps flavor the veggies.
- Cook cauliflower for about 5-7 minutes until just tender but still firm. If using potatoes, adjust the time slightly if they are in the pot together.
- Always rinse under cold water right after draining. This step stops the cooking process and helps them stay crisp.
Remember, the goal is a gentle crunch that gives structure to the salad! Enjoy your cooking!

Step-by-Step Instructions:
1. Preparing the Cauliflower and Potatoes:
Start by bringing a large pot of salted water to a boil. Once boiling, add the cauliflower florets (and the diced potatoes, if you choose to use them). Cook them for about 5-7 minutes until they’re tender but still firm. Be careful not to overcook! After they’re done, drain them and rinse under cold water to stop the cooking process. Set them aside to cool completely.
2. Making the Dressing:
In a large mixing bowl, add your mayonnaise, sour cream, Dijon mustard, lemon juice, apple cider vinegar, salt, and black pepper. Use a whisk to mix everything together until smooth and creamy. This dressing is what will bring all the flavors together, so mix well!
3. Combining the Ingredients:
Once the cauliflower and potatoes are completely cooled, gently add them to the dressing in the bowl. Toss everything together carefully so that the veggies are evenly coated with the creamy dressing.
4. Adding Fresh Herbs:
Now it’s time to fold in the diced red onion, chopped dill, and parsley. These fresh herbs will add a wonderful flavor to your salad! Mix gently to combine.
5. Taste and Adjust:
Take a moment to taste your salad. If you feel it needs a bit more salt, pepper, or even an extra squeeze of lemon juice, go ahead and adjust the seasoning to your liking.
6. Chill and Serve:
Cover the salad and chill it in the refrigerator for at least 1 hour. This allows all the flavors to meld together beautifully. When you’re ready to serve, give it a good stir, then garnish with fresh dill sprigs and a light sprinkle of smoked paprika.
7. Enjoy!
