Keto Potato Salad

When it comes to potato recipes given a keto makeover, my favorites to make are french fries, hash browns, and this keto potato salad. 

Growing up, potatoes were one of my staple foods. I think it’s a fair assumption to say most kids (and adults) would choose potatoes to be their vegetable of choice and one they could easily consume on a daily basis.

One of my favorite potato dishes was always a classic potato salad. I know everyone says their mom’s salad is the best but really, my mom’s one takes the prize for it. Her version involves adding gherkins (unsweetened pickles) and dill to the dressing, and when she’s being fancy, she adds a sprinkling of chopped and grilled bacon!

Now, since going keto, potatoes have been a big no-no. It’s not that they can’t be eaten on a keto diet, but if you were to eat one small potato, you’ve pretty much hit half your daily net carb count. Luckily, you can easily make a mock potato salad with a secret ingredient that tastes like actual potatoes- Rutabagas! 

Keto Potato Salad with NO cauliflower

Rutabagas have easily been my favorite potato substitute since going keto. I know people lament that cauliflower is a great alternative but no. It isn’t as versatile as the rutabaga, and it certainly can be used to make fries. Something else it can’t easily replicate potatoes in? Potato salad!

Since finding the wonders of the humble rutabaga, I’ve used it to make this keto potato salad recipe. It’s chunky, creamy, and loaded with different textures. It tastes EXACTLY like your favorite potato salad and has hints of tang and saltiness from the gherkins and bacon, respectively. 

I had some friends over for a barbecue the other day and served this salad was included on the menu and NO ONE could tell that it wasn’t actually potatoes in it- It tasted like any good potato salad!

How do you make a keto potato salad?

The Ingredients

  • Rutabagas– Also known as swedes, rutabagas make a fabulous alternative to potatoes. They have a similar flavor and texture, and the only difference is the carb count! Per 100 gram serving, rutabagas contain just 6 grams of net carbs (compared to potatoes, which are close to 19 grams!).
  • Gherkins– Pickled cucumbers with no added sugar. These add some delicious tangy flavor and balance out the mayonnaise. 
  • Mayonnaise– Skip the store bought version and make some homemade keto mayonnaise
  • Dijon mustard– The best tasting mustard. You can use American or English mustard, just be sure they have no added sugars in them. 
  • Lemon juice– Just a touch. 
  • Dill– A must for any good potato salad! 
  • Bacon OR pancetta– Optional, but highly recommended. You can never go wrong with some fried bacon or pancetta, especially if it’s in a potato salad. 

The Instructions

Start by peeling and chopping your rutabaga into 1-inch pieces. Place the diced rutabaga into a large pot and cover with tap water. Add some salt and place it over medium heat. Once it begins to boil, reduce it to low and let it cook until tender, around 10 minutes. Drain the rutabaga and place it into a large mixing bowl, letting it cool slightly. 

Now, in a separate bowl, add the remaining ingredients and mix very well. Add the dressing into the bowl of rutabagas and gently mix together, until incorporated. Cover the bowl and refrigerate for at least an hour, for the flavors to meld.

Tips to make the best low carb potato salad

  • Keep a firm eye on the rutabaga as it is boiling. You want to remove them from the heat when they are just tender, not soft. If they become too soft, you risk them falling apart once we add the dressing. 
  • Your rutabagas don’t need to be room temperature before mixing it with the dressing. Refrigerating the salad before serving allows for the flavors to settle and the dressing to stick to the rutabagas.
  • For a higher protein potato salad, feel free to add in chopped boiled eggs. 

Storing and freezing potato salad

While potato salad is always recommended to enjoy the day of, it actually tastes even better after several days!
