This recipe is made with regular potatoes which have become accepted in the Paleo community.

They are 100% Whole30 compliant because, as the Whole30 program says, they are a “whole, real, nutrient-dense food.” How nutrient-dense are they? Well according to PaleoLeap, one white potato has 70% of your vitamin C needs and 25% of your potassium needs for one day.

I have found it interesting to read various opinions on this and enjoyed reading the Are White Potatoes Paleo? article by PaleoHacks.

  • Slice your red potatoes into 1 inch thick slices. Put them into a large pot of boiling water, and cook for about 20 minutes. Make sure you can easily stab them with a knife before taking them out.
  • While the potatoes are cooking, put all of the tuna into a bowl and mix with a fork, cutting up the larger chunks of tuna into smaller pieces.
  • While the potatoes are cooking, you can also make the French dressing. Mix 8 Tbs olive oil, 4 Tbs tarragon vinegar, 2 Tbs dijon mustard, 1 tsp sea salt, 3/4 tsp ground black pepper, 1/2 tsp herbs de provence, and 3 Tbs diced fresh parsley together until a thick dressing forms.
  • Once the potatoes are cooked, transfer them to a large bowl and cut them into smaller pieces while mixing them up. Do this while they are still warm. You want there to be various sizes of potato in the salad.
  • Add the tuna to the bowl of potatoes and mix. Then, add the diced white onions and sliced scallions to the bowl and mix.
  • Lastly, add the French dressing to the bowl and mix.
  • Serve warm with a side of tomatoes, radishes, pickles or any other veggie of your choice.
  • You can also refridgerate it and eat it cold later.


If you don’t have tarragon vinegar, apple cider vinegar works great.
Dried parsley works well instead of fresh.
If you don’t have herbes de provence, use a sprinkle of basil, rosemary and thyme instead.

  1. This recipe seems to call for 25 oz tuna. That would be over 1 1/2 lbs or 709 grams. It is probably a misprint for 2 cans of tuna.5 oz each.

  2. Easy, and yummy! Great summer recipe. My kids who like mustard really loved it. The non mustard kids took a pass.5 stars

  3. This is wonderful especially with the pickles,radish and tomato on the side.

    I used apple cider vinegar and 1/2 t dried tarragon. I will make tarragon vinegar for future use.

  4. Simply delicious and easy breezy to pull together.  Took recommendations for radishes and pickles and they were perfect sides.   Not a morsel was left.  Cheers 5 stars

  5. Saw something similar in a magazine, looked all night for it,couldn’t remember where, turned to tuna potato internet clues. Your recipe was so sharing. And I think very authentic. Perfect tarragon dressing instead of lemon and so easy. Less snacking after some potato.5 stars

  6. This was seriously delicious! I didn’t have some ingredients so subbed herbes de provence  for a mix of rosemary, marjoram and thyme. Plus baby rocket instead of parsley. Would definitely make again!5 stars

  7. I made this. Without tarragon vinegar. I rarely eat canned tuna. I like potato salad but don’t always enjoy mayo that’s in most recipes. This recipe looked perfect for summer. It was also the first time I used Herbes de Provence. My family enjoyed it! It’s a simple and easy tasting dish. 

    1. I’m very happy you guys enjoyed it! It’s honestly my favorite way to make potato salad. 🙂
