Is Canned Tuna Good for a Keto Diet?

Canned tuna is a great source of protein that can be enjoyed in moderation as part of a Keto diet. Rich in heart-healthy omega 3 fatty acids, tuna makes a versatile and relatively inexpensive addition to your weekly meal rotation. Perfect combined with added fats to make our delicious Keto tuna salad, tossed through low carb spaghetti or flaked into omelets.

Is Mayonnaise Keto?

Mayonnaise is an excellent choice as a Keto condiment. Naturally rich in fats, mayonnaise is prepared with a base of Keto friendly ingredients. Store-bought mayonnaise can contain added sugars and additives however, that are not Keto compliant. Be sure to check the labels to find a suitable option. Alternatively, you can use our own Keto homemade mayo for your tuna salad. You can find the recipe for this in our sides section.

  • Step 1

    Add all the ingredients to a mixing bowl. Mix together until well combined. If you would prefer a chunkier tuna salad, you can dice the avocado into small pieces and mix. For a creamier tuna salad, mash the avocado with the mayonnaise before mixing it into the tuna. Keep refrigerated until ready to serve.

    Tuna salad is a go-to for me and I frequently take it to work for lunch. I keep the avocado and lime separate (use the lime to keep the avocado from darkening), and I omit the green onions. To flavour, I add curry powder! When I’m ready for lunch, I stir the avocado into the tuna salad. use celery sticks to scoop it up. It’s delicious!

        I am enjoying this for lunch. It's easy and quick to prepare. A good starter. Very satisfying with the crunchiness of the lettuce.

          I did this for my weekly meal prep. I prepared the sauce first in a container, with tuna and avocado separate. I thought the sauce was way too citric but once mixed, it was a subtle aroma only. It isn't the most fragrant flavor compared to just avocado and tuna, but it's a nice change.

            Not a fan of cilantro, so subbed with fresh dill. Added diced celery and cucumber for a little crunch. No lime in the house so used fresh lemon juice. DELISH!!!

                Added extra Mayo and used avocado half and a good teaspoon of Lime… So I registered it as 1.5 servings. Made it in chunks and chopped some rocket leaves in…. I found it tasty!

                  The texture was like cat food. I just couldn’t get past how mealy it was. Unfortunately, this one is a no for me. i guess maybe I just need a ton of mayo in my tuna salad

                  How long did this last refrigerated i.e. did it not brown due to the avo in the recipe? Orndid the lime juice keep it from going black?

                    Lime juice would help but I bet the mayo helped more. I don't really know though.

                  OMG!! This was positively delicious! I used albacore tuna, added a bit more onion and diced dill pickle. Yum!! This will become a favorite.

                    Celery adds a great crunch in it as well. I make little taco melts with it using the low carb street tacos. So good

                      Nice! I'm not a huge fan of onion, so I subbed in dill pickle relish and pulled back on the salt and citrus. Diced the avocado and plunked it on top so I didn't create a mush mountain. LOL

                          Be careful with fish. people mistakenly assume they can eat as much as they like because of the health benefits. It is advised to eat fish no more that 3 times a week because of the mercury found in fish. Small amounts are safe and albacore tuna is considered one of the safer fishes to eat regularly.

                        Do you need to cook the tuna first?

                                I didn’t like at all. I’ll use mayonnaise in my tuna salad. In fact eating it straight out of the can would taste better to me. That said, I love avocado and egg salad
