  • Canned tuna – An absolutely delicious and versatile pantry staple, canned tuna is so economical without sacrificing taste.
  • Mayonnaise – Mayo makes this tuna salad creamy and rich. Check out the top tips for how to pick out a mayonnaise that’s perfect for the keto diet.

  • Dill relish – Relish made from dill pickles adds another great layer of flavor — a little tart, a little sweet — with an amazing crunch.
  • Lemon juice – Just a splash of lemon juice adds a bit of acidity and bright citrus flavor that brings out the celery and pickles.
  • Garlic – You may have never considered adding minced garlic to your tuna salad, but, trust me, once you add a taste of garlic, you’ll never go back!

Top Tips For Making

  • Your tuna salad will keep in the fridge in an airtight container for 3-5 days. This makes it perfect for meal prep for basically a whole week!
  • While on keto, avoid mayonnaises that are light, fat-free, reduced-fat, or sweetened. These are all going to be lower in fat and higher in carbs than regular mayo, and therefore not ideal. You can use mayos that have avocado or olive oil in them, but make sure that the flavor isn’t so strong that it leaves the tuna salad with a funky aftertaste.

  5. Pretty good. Just wish it had more flavor.3 stars

    1. Megan | 40 Aprons Team Megan | 40 Aprons Team says:

      So sorry the flavor was lacking for you, Patty! If you make it again, you can definitely increase the amount of garlic, salt, and pepper you use. Depending on the level and type of flavor you’re wanting from it, you might try a chipotle mayonnaise instead of a traditional mayo. Thank you for leaving a review!

  6. How was nutritional information calculated without knowing serving size? Or is the information for the whole amount

    1. Megan | 40 Aprons Team Megan | 40 Aprons Team says:

      Hi, Tom! The recipe yields 4 servings, and the nutrition information shown is for 1 serving out of 4, or 1/4 of the total amount of tuna salad made. The nutrition info shown is approximate, though, and macros will vary depending on the specific ingredients you use.
