Recipe Overview

Time: 10 Minutes

Ingredients: Canned tuna, mayo, dill, parsley, green onions, mustard, salt, lettuce, tomato, and sourdough.

Ease: Super Easy

Ingredients & Substitutions

Albacore Tuna - Albacore has a mild flavor and firm texture that holds up well in tuna salad. Using tuna packed in water keeps it lighter and lets the herbs stand out, while tuna packed in oil adds a richer, more savory flavor.
Mayo - Light mayo gives a more subtle flavor so the herbs can really shine. Use regular mayo for a creamier, richer taste, or swap in Greek yogurt for a tangier, lighter option.
Fresh Herbs - A mix of dill, parsley, and green onions gives the tuna salad a bright, fresh flavor. You can substitute with chives, basil, or cilantro for a slightly different twist.
Mustard - A little mustard adds depth and brightness. I like using yellow mustard for a classic flavor, but Dijon will give it a bolder, slightly tangy kick.
Bread - I really like using sourdough, it's sturdy and adds a nice tang. Whole wheat or your favorite sandwich bread will work too.

Tips for Making Herby Tuna Salad Sandwich

Types of Tuna

Albacore tuna: Mild flavor and firm texture - great for sandwiches.

Chunk light tuna: Softer texture and a stronger seafood flavor.

Packed in water: Keeps the salad lighter and fresher.

Packed in oil: Adds richness and a more savory taste.

Variations

Add crispy bacon for extra flavor.
Mix in diced celery or pickles for crunch.
Swap in Greek yogurt for part of the mayo for a tangier flavor.
Use Dijon mustard instead of yellow for a bolder twist.
Add diced hard-boiled eggs for extra protein and a classic touch.
Add a squeeze of lemon juice for a brighter, fresher, and tangier flavor.

Common Questions

What part of the green onion do I use?

Use the white and light green parts for a mild onion flavor. The darker green tops can be added for an extra pop of color.

What's the difference between curled and Italian parsley?

Italian (flat-leaf) parsley has a stronger, more robust flavor, while curly parsley is milder and more about texture and garnish. I used Italian in this recipe.

Can I use dried dill and parsley?

Use about ⅓ of the amount of dried dill and parsley as called for fresh. Dried herbs are more concentrated. The flavor will be less bright, but still good.

How long will my tuna salad last in the fridge?

Tuna salad will keep for up to 3 days in the fridge. Stir it before serving, since the ingredients can settle at the bottom.

How can I avoid a watery tuna salad?

Make sure to drain your tuna really well. Press out any excess liquid with a fork or paper towel.

Make Ahead

Prep the Tuna Salad - Make it up to 3 days ahead, then store it in the fridge. The tuna salad will actually taste better after a few hours since the flavors have more time to meld together.

Sandwich Time - Wait to make the sandwiches until just before serving to keep the bread from getting soggy. If you're packing it for lunch, store the tuna salad, tomatoes, and lettuce separately from the bread.

Sides for recipe

Easy & Crunchy - Serve chips or pretzels.
Easy & Fresh- Pair with fruit like grapes or apple slices, or vegetables like cucumbers and carrots.
Warm & Cozy - Eat with a bowl of soup, like Tomato Soup orPotato Soup.
