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.

Mellissa, I’m looking for the 7 day keto kick start program with bacon and egg breakfast, chicken salad lunch, soup dinners, stuffed celery snacks. It was how I started my keto journey and lost over 60 pounds. After several years I’ve put on 15 pounds and want to lose it fast. That plan got me into keto fast and worked great for 3 repeated meals each day. But I can’t find it now! Help please
Mellissa Sevigny says
Hi Susan, this sounds like a merge of a few of my plans – there is the soup diet, which could be what you’re describing, but also one of my weekly keto plans so it’s hard to tell. I recommend perusing the

This is a classic lunch for our family great recipe.
Jessica says
Easy, simple, and delicious. I made this first on the soup diet plan, but now I make it for a snack or lunch every other week or so. So much protein and the onion flakes add a nice flavor!

My ideal tuna salad has chopped celery and capers and mayo. That’s it. Maybe a little celery seed, too.
Modern Fit says
Thanks for sharing this recipe Melissa! I added some paprika to the tuna for a little extra kick :)
Deb says
I love tuna salad…..a can of tuna is always in my pantry for emergencies (read: too tired to cook). My favorite zero carb addition is to add between 1/2 tsp or so of dried dill weed to it…..really adds a bright note to all the creaminess. Fresh dill is obviously even better if you have it. Toss in a few capers if you are feeling zingy.

I do the exact same thing(:
Rebekah Phillips says
I am from Australia & wonder how many ounces of tuna to use?
Mary Wood says
Hi Rebekah … I’m from Australia too … I haven’t been able to find out either. Even if it was in ounces we could go online and do the conversion to grams ☹
Flori says
A can of tuna in the United States is about 5oz or 142grams. Hope this helps!
Debbie says
Cans of tuna in Canada are usually 170 grams, undrained

I added a sliced boiled egg and sliced almonds on top of a chopped salad. Great idea using onion flakes. Next time I may add celery flakes. Thanks for a healthy simple meal idea!
Ari says
Hi there, Firstly, love your recipes! And second, could you say how much the can of tuna weighs please. I’m not from the US so have no idea which can is the right size to get. Thank you.
Elizabeth F. says
I’d say the smallest can available. In the United States, it’s 5 oz. net weight.

I’ve been using dried onion flakes for tuna salad. It gives great flavor. And apart from that, it is good for the health especially if you are diabetic.
