This easy keto tuna salad is a high protein, low carb staple that uses only a few ingredients that you probably already have in your pantry. A delicious tuna salad that can literally be thrown together in 5 minutes or less.

Don’t freak out! I know I’m posting an easy keto tuna salad recipe, but this doesn’t mean I’ve run out of recipe ideas or gone off my rocker! You probably know how to make keto tuna salad, but since I have it coming up a new meal plan I’m working on, I wanted it here as an easy reference with nutrition information included.
Not that you can’t figure out how to make a low carb tuna salad on your own – and probably do already, but I will say that my easy keto tuna salad recipe is pretty delicious though. It’s my son’s favorite, and the secret is in the dried onion flakes. They add a punch of flavor without the harsh sulfur burn of fresh onions that can turn some people off.
If you’re eating it right away, it also adds a little crunch, which we all love!

I’m calling for canned tuna in water, because I’d rather add my own fat in the form of mayonnaise (homemade if you have it – especially if you’re Whole 30) than have it swimming in low quality oil of questionable origin.
That being said, if you can get some decent tuna in olive oil or another good quality oil then that’s ok too, but you should probably calculate your own nutrition info since the fat and calories will likely be higher than in this easy keto tuna salad recipe.

This recipe calls for salt and pepper to taste because some tuna fish is saltier out of the can than others. I recommend mixing it without salt and pepper, tasting it and then adding what you think you’ll need at that point.
Look for a new addition to my free weekly keto meal plans featuring this easy keto tuna salad coming soon!

Mellissa your recipes are so tasty and easy o follow. You must be a professional chef and/or instructor. Follow your directions and I end up with some great foods.
I make sweet pickle relish by adding sugar substitute to dill pickle relish. Then let it sit in fridge for a while.
My favorite recipe right now is egg fast custard, Just made the chicken vegetable soup, WOW, new love for turnips and radishes. You are AMAZING!!
Just finished egg fast, saved my diet, back within 3 of my low and back on track.
Thank you Mellissa for all your posts and help and great tasting food.

Can this be substituted with chicken? If so how many oz? Thank you.

This is not Paleo if you use a commercial mayonnaise, like Duke’s or Hellmann’s. You a brand like Primal Kitchen or Chosen made with Avocado oil, no sugar or make it yourself very easy.

I usually like a little crunch, so I chop up some water chestnuts and add it to the mixture. And maybe a little chia or poppy seed.
David Swails says
Hello Peeps!!! Very good addition I added celery seed and a touch of mustard. Thanks, my 91year old Dad loves it to!!!
Mellissa Sevigny says

Nutrition info says 19 grams of carbs? That doesn’t seem right. Can you confirm please. Thank You.
Karen says
Never mind, I put my eyes on and see my mistake, it’s 2 grams. My apologies.

Hi there, I just made this for my lunch, very tasty and so quick to make. However I’m not sure how this classifies as keto. Ketogenic meals are meant to be lower in protein (15-25%), with fat being the major nutrient (70%) and of course very low in carbs (<10%). So although this recipe is tasty and simple it certainly isn't keto.
Mellissa Sevigny says
Keto isn’t low protein, it’s moderate protein.
Ryan Luedecke says
Thanks for publishing simple recipes like this Mellissa. I personally love the simple ones. Didn’t know about adding the dried onion flakes. I’m going to try that in lieu of relish.

I use a generous sprinkling of Mrs. Dash Original Blend and some dill relish. Easy and tasty! Works with chicken salad, too.
Kirsten says
I like to stir premade guacamole with a can of tuna. It has all the seasonings in it already. Looks weird but tastes awesome!
Kristi says
I’m going to try this for my son that’s allergic to eggs!!! Thank you!!
