A classic and flavorful dish that is perfect to make in advance and enjoy throughout the week. Just as delicious on its own as it is on a sandwich or over salad greens. Ready in just 15 minutes! 


  • 2 5-ounce cans water packed tuna, drained
  • 1/4 cup finely diced red onion
  • 2 stalks celery, finely diced (about 1/2 cup)
  • 2 tablespoons chopped parsley
  • 1/31/2 cup avocado oil mayonnaise, based on your preference (try this recipe for avocado oil mayonnaise for a homemade option!)
  • 1 teaspoon Dijon mustard
  • 2 teaspoons lemon juice or red wine vinegar
  • 1/2 teaspoon kosher salt, or to taste
  • 1/4 teaspoon black pepper, or to taste


  1. Drain tuna and transfer to a large bowl. Break apart into small pieces using a fork.
  2. Add all remaining ingredients except salt and pepper – red onion, celery, parsley mayonnaise, mustard, and lemon juice. Mix to thoroughly combine. Season to taste with salt and black pepper and add a little more mayonnaise if desired.
  3. Serve and enjoy! Serve immediately or store in a covered container in the refrigerator until ready to serve.


If stored properly in an airtight container, homemade tuna salad can last in the refrigerator for up to four days. However, it is essential to use fresh ingredients and to ensure that the tuna salad has been properly refrigerated at all times.

You can freeze tuna salad. However, it’s important to keep in mind that the texture and taste may be affected once it’s thawed. The mayo in the tuna salad can separate and become watery, so it’s best to freeze it in an airtight container to minimize any air exposure. When you’re ready to use it, let it thaw in the refrigerator overnight, give it a good stir to redistribute any separated ingredients, and add a little extra mayonnaise before serving if needed.
