Low Carb Tuna Salad

Keto Tuna Salad Ingredients

3 cans (5oz ea.) tuna, drained
⅓ cup mayo of choice (or Greek yogurt)
2 Tbsp diced red onion
3 Tbsp diced celery
2 Tbsp relish (dill for low carb, or sweet relish)
1 Tbsp pickle juice (optional)
1 tsp lemon juice
3 Tbsp chopped pecans
salt & pepper to taste

Is Tuna Salad Keto or Not?

In general, fish can be a great option for a keto diet, especially fattier fish like salmon and tuna. When it comes to whether tuna salad is keto or not, it depends how you make it. The classic tuna salad recipe—canned tuna, mayo, veggies, and seasonings—is already pretty keto friendly!

You can maximize the fat content by using real, full-fat mayo, and I personally prefer avocado oil mayo. Keep the veggies low carb, like onion and celery, and explore higher fat additions like pecans!

For this particular low carb tuna salad recipe, the relish and pickle juice may be of concern to some, depending on your individual carb tolerance. You can use sweet relish and pickle juice if you want a more noticeable sweet flavor, or you can keep your tuna salad keto by using a dill relish instead—no sugar to worry about. You’re free to nix the splash of pickle juice as well, but I like the hint of sweetness, and the added sugar is negligible!
