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.

Thanks for the onion flakes idea. I’m curious about your recommendation for Hellman’s real mayonnaise after your comment about tuna being packed in questionable oil. You don’t have concerns about the soybean oil used in the mayonnaise?
Sandra Malluck says
I found that omitting the mayo and replacing it with 2 tbs of olive oil and 2 tbs of wine vinegar is delicious. A slice of onion and a rib of celery makes it delish and isn’t many carbs.
Dirk says
I really, really like to add capers to mine. Now I always think something’s missing if rhey aren’t there. I’m looking forward to trying the onion flakes.
Mark A says
I sometimes use small bacon bits and shredded Sharon cheddar.
Liz says
Do the onion flakes become hydrated right away ? Love the simplicity
Mary Anna says
I sometimes do celery, chopped small, for the crunch.
Jennifer McLean says
Yep, I know how to make tunafish low carb, in fact, I actually use Hellmann’s too. Now, don’t think no one leaned anything because I never thought of using DRIED onion flakes! What a brilliant idea. Not only will it add flavor, but if you doesn’t finish all the tuna, you can put it in the fridge and that yucky liquid that usually comes off will be soaked up by the dried onion. I’m also gonna add dried celery flakes too. Thanks for the tip. See, you can learn something even with simple recipes!
Eric says
I add some drained dill (NOT sweet) pickle relish to mine, but I’ll try the onion flakes, too.

I recently invented buffalo tuna dip lol
Just tuna, mayo ranch and Frank’s red hot. So good
Deerave says
I make the same with chopped chicken over a bed of chopped celery
Julie says
Very good. I do this also.

I put green olives in mine. It’s my lunch at work everyday.
