What’s in the Mix

Tuna: Be sure to drain the tuna (whether it’s water or oil-packed) and flake it with a fork before adding in Step 3 so the pieces are bite-sized.

Dressing: Use full-fat mayonnaise and your favorite mustard brand for best flavor.

Tricks for Tuna Salad Success

  • Keto tuna salad tastes best when it’s made up to a day ahead and served extra cold. This allows the flavors to blend even more.
  • Adjust the amounts of mayonnaise and mustard depending on how creamy you want the recipe to be.

Keeping It Fresh

Keep leftover keto tuna salad in a covered container in the refrigerator for up to 3 days. Stir in a dash of lemon juice to freshen the flavors before serving with cloud bread, on a bed of lettuce greens, or even spread into a stalk of celery for a quick and simple snack. Freezing tuna salad isn’t recommended since it will thaw out too watery.
