Salads
This tuna salad recipe with egg and mustard transforms simple pantry staples into a creamy, protein-packed masterpiece with just the right balance of tangy mustard and rich yolk richness. The secret lies in the texture—chunky celery bites add satisfying crunch, while hard-boiled eggs bind everything together with velvety yolk magic.
I’ve perfected this version over years of lunchbox testing, ensuring every bite delivers that perfect harmony of flavors without overpowering the fresh tuna.
What sets this recipe apart is the mayo-to-mustard ratio, which keeps the dressing bright and tangy without being sharp. The eggs aren’t just for binding—their yolks melt into the mix, creating a luxurious creaminess that makes this salad feel like a gourmet spread.
For extra texture, I always include crispy celery, but feel free to swap in red onion or pickles if you prefer a different bite. The result? A salad that’s hearty enough for a main dish but light enough for a sandwich or crackers.
The beauty of this recipe is its versatility—it works as a filling for wraps, a topping for avocado toast, or a standalone dish with a sprinkle of fresh herbs.
Store it in an airtight container for up to 3 days, though I’ve found it tastes even better the next day as the flavors meld. Whether you’re prepping for meal prep or craving a no-fuss lunch, this tuna salad delivers restaurant-quality results with minimal effort.
For those who love texture contrasts, I recommend adding a pinch of smoked paprika or a squeeze of lemon juice before serving—it elevates the flavors without complicating the process. The key is balancing the ingredients so the mustard shines but doesn’t overpower, while the eggs add that luxurious finish.
Trust me, once you try this version, you’ll never go back to the basic mayo-heavy tuna salad again.
Ingredients for tuna salad recipe with egg and mustard
Pantry staples meet fresh ingredients for a tuna salad that’s creamy, tangy, and packed with texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Tuna Packets 🐟 | 2 cans | High-quality, drained well |
| Large Eggs 🥚 | 2 whole | Hard-boiled, chopped yolks reserved |
| Mayonnaise 🥫 | ½ cup | High-quality, full-fat preferred |
| Dijon Mustard 🍯 | 2 tbsp | Classic or whole-grain variety |
| Celery Stalks 🧅 | 2 whole | Finely chopped, crisp texture |
| Red Onion 🧅 | ¼ cup | Finely diced, for brightness |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, brightens flavors |
| Smoked Paprika 🌶️ | ½ tsp | For subtle smokiness |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Fresh Dill 🌿 | 2 tbsp | Chopped, for freshness |
| Extra-Virgin Olive Oil 🫒 | 1 tsp | For drizzling on top |
The tuna is where it starts—high-quality packets make all the difference. I always grab the Wild Planet or Vital Choice brands from the grocery store’s seafood section (they’re worth the extra buck). Freshness matters here: if the tuna smells fishy when you open it, toss it. The eggs? Hard-boiled the day before saves time, and I always reserve the yolks—they’re the secret to that luxurious creaminess. For the mayo, Hellmann’s or Duke’s are my go-tos, but any full-fat mayo works. The mustard? Dijon is non-negotiable—it’s got that perfect balance of tang without being overpowering.
No Dijon? Yellow mustard at half the amount works in a pinch, but you’ll lose some depth. The celery should be crisp—if it’s limp, toss it. For extra crunch, add a pinch of celery seeds when you chop it. Swapping in red onion? Pickle the slices first for 10 minutes to mellow the bite. Fresh dill is ideal, but dried dill at one-third the amount gets you close. The smoked paprika adds warmth without overpowering—skip it if you’re sensitive to smoky flavors. And that lemon juice? Freshly squeezed is key—bottled just won’t cut it.
This salad keeps beautifully—3 days in the fridge in an airtight container, though it tastes even better the next day as the flavors meld. For meal prep, I portion it into small containers with a drizzle of olive oil on top to keep everything fresh. The celery stays crisp if you add a paper towel to absorb moisture. Freezing isn’t recommended, but you can freeze the base (without celery or onion) for up to 1 month—just add fresh toppings when you’re ready to eat. Leftovers? Perfect for wraps or crackers—just add a squeeze of lemon before serving.
Why You'll Love This Recipe
- No Chopping Needed: I swear by the fresh tuna packets here—just drain, flake, and mix. That celery gets diced in 30 seconds, but honestly? You could skip it if you’re in a rush. The mustard and mayo handle the texture game while you’re still debating what to eat for lunch.
- Eggy Magic Boost: Between us, that hard-boiled egg transforms this from good to ridiculously good. The yolk adds richness, the white keeps it light, and the mustard ties it all together like a secret handshake. (Yes, even on a Tuesday night.)
- Lunchbox Hero: This salad holds up like a champ—pack it in wraps, slather it on crackers, or stuff it into a pita. My kids grab it for school lunches, and I take it to work when I’m too tired to think. The mustard keeps it from getting soggy, and the tuna stays fresh for days.
- Budget Meal Stretch: Fresh tuna packets are cheaper than you’d think, and eggs? Always affordable. A single batch feeds four lunches, and leftovers taste just as good cold as they do fresh. I’ll be real: this is my go-to when I’m trying to make groceries last longer without sacrificing flavor.
Step-by-step instructions for tuna salad with egg and mustard
Here's how to create a perfectly balanced tuna salad with creamy texture and crispy celery bites.
Prepare the Hard-Boiled Eggs
Place the 2 whole large eggs in a small saucepan and cover them with cold water by about 1 inch. Bring to a boil over high heat, then immediately reduce to a gentle simmer for exactly 9 minutes. This timing ensures perfectly set whites while keeping the yolks runny for that creamy texture.
Transfer the eggs to an ice bath for 10 minutes to cool completely. Once cooled, peel the eggs and chop the whites into small pieces. Reserve the yolks—they'll be our secret weapon for that ultra-creamy finish. The yolks should remain slightly thick but still spreadable when you press them gently with a spoon.
Mix the Base Ingredients
In a medium bowl, combine the drained 2 cans of fresh tuna packets with the 0.5 cup mayonnaise and 2 tablespoons Dijon mustard. Use a fork to gently break up the tuna while mixing until just combined—you want to preserve some texture rather than making a smooth paste. This keeps the salad light and fluffy.
Add the 2 tablespoons chopped fresh dill and 0.5 teaspoon smoked paprika to the mixture. The dill will add bright freshness while the smoked paprika gives a subtle depth that complements the tuna beautifully. Mix everything together until the paprika is evenly distributed and no dry spots remain.
Incorporate the Crunchy and Fresh Elements
Finely chop the 2 whole celery stalks—you want tiny pieces that will add texture without overpowering the salad. Add them to the bowl along with the 0.25 cup finely diced red onion. The celery provides that signature crunch while the onion adds a bright, sharp contrast that cuts through the richness.
Finally, add the 1 tablespoon freshly squeezed lemon juice and 0.5 teaspoon salt. The lemon juice brightens everything up while the salt enhances all the flavors. Mix gently but thoroughly—just until all the ingredients are evenly distributed. You should be able to see all the components while still maintaining a cohesive texture.
Create the Creamy Yolk Magic
In a separate small bowl, mash the reserved 2 egg yolks with a fork until they're completely smooth and creamy. This is where the magic happens—the yolks will transform your tuna salad from good to extraordinary. Slowly fold the mashed yolks into the tuna mixture using a rubber spatula, working gently to maintain the airy texture.
For the final touch, drizzle the 1 teaspoon extra-virgin olive oil over the top and gently fold it in. This adds just the right amount of richness and helps everything come together beautifully. Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of lemon juice to balance the flavors perfectly.
Pro Tips For Making Tuna Salad Recipe With Egg And Mustard
- Drain Tuna Properly: Fresh tuna packets release way more liquid than you’d expect—don’t just dump them straight into the bowl. Open the packet, pour the tuna into a fine-mesh strainer, and let it sit for 2 minutes while the excess moisture drains. This keeps your salad from turning into a soggy mess, especially when adding the egg later.
- Chill Eggs First: Hard-boil your eggs, then plunge them into ice water for 5 minutes before peeling. The shock stops the cooking process and makes the shells slide off like magic. Once peeled, slice them into ¼-inch pieces—thicker slices stay rubbery, and thinner ones get lost in the mix.
- Balance Mustard Ratio: Dijon mustard is bold, so start with just 1 teaspoon and taste before adding more. Too much turns your salad bitter; too little makes the flavor feel flat. Mix it into the mayo first, then fold in the tuna—this way, the mustard distributes evenly without clumping.
- Add Celery Last: Celery soaks up mayo like a sponge, so chop it into tiny dice (about ⅛-inch) and stir it in after everything else is combined. If you’re short on time, swap half the celery for finely diced red onion—same crunch, brighter flavor, and no extra prep.
Storing and reheating this tuna salad recipe with egg and mustard
Fridge Storage Tips
Store your tuna salad in an airtight glass container with a tight-sealing lid—I love using Pyrex or Le Creuset containers. Keep it refrigerated at 40°F or below for up to 3 days, though I’ve found the flavors actually deepen overnight as the mustard and lemon brighten the tuna.
For extra freshness, place a paper towel on top of the salad before sealing to absorb any excess moisture that could make the celery soggy. 🥫
Freezer-Friendly Base
While I don’t recommend freezing the full salad (the celery and onion get mushy), you can freeze the base mixture—just the tuna, mayo, mustard, and egg yolks—for up to 1 month. Use a freezer-safe silicone mold or quart-sized freezer bag with all air squeezed out.
When ready to eat, thaw overnight in the fridge, then stir in fresh celery, onion, and herbs. The texture won’t be perfect, but it’s a great backup for busy days. ❄️
Reheating for Maximum Freshness
For the best texture, never microwave the full salad—it turns rubbery. Instead, reheat portions gently on the stovetop: place the salad in a nonstick skillet over low heat for 2-3 minutes, stirring occasionally.
Add 1 teaspoon water or lemon juice to keep it moist. For extra flavor, finish with a drizzle of olive oil and a pinch of smoked paprika right before serving. 🔥
Reviving Day-Old Salad
If your salad tastes a little flat after a day or two, don’t toss it! Stir in 1 tablespoon fresh lemon juice and 1 teaspoon Dijon mustard to revive the brightness. For texture, add extra chopped celery or red onion—the crunch cuts through any richness.
A sprinkle of fresh dill or parsley also works wonders to wake up the flavors. Trust me, it’ll taste like new! 🌿
Portioning for Meal Prep
Divide your tuna salad into small glass containers (like Mason jars) for easy grab-and-go lunches. Store the celery and onion separately in a small airtight container with a paper towel to keep them crisp.
When ready to eat, mix everything together and add a squeeze of lemon. This keeps your salad fresh for up to 5 days without sacrificing texture. Perfect for busy weeks! 📅

Frequently asked questions
Can I use canned tuna instead of fresh tuna packets?
Yes, but with a few adjustments! Use high-quality canned tuna in water or oil (drained well) and add 1 extra tablespoon of lemon juice to brighten the flavor. For texture, gently flake the tuna with a fork instead of breaking it up completely. Avoid tuna packed in water with BPA lining for better taste.
How do I make this tuna salad extra creamy?
Add the reserved egg yolks (mashed smooth) and 1 tablespoon of sour cream or Greek yogurt for richness. For a vegan version, swap the mayo for vegan mayo and add 1 tablespoon of avocado puree. The key is balancing moisture—don't overmix after adding creamy elements!
What if my tuna salad tastes too sharp from the mustard?
Balance it by adding 1 extra tablespoon of mayo or 1 teaspoon of honey/maple syrup to mellow the tang. A pinch of sugar also helps, or simply add more lemon juice to brighten other flavors. Taste as you go—this salad is all about personal preference!
Can I make this ahead for a party?
Prepare it 1 day ahead and store in an airtight container. For serving, add fresh chopped celery, red onion, and herbs just before guests arrive to keep everything crisp. Keep the salad chilled until 30 minutes before serving so flavors meld beautifully.
What's the best way to serve this tuna salad?
Try it on toasted sourdough crostini, stuffed into butter lettuce wraps, or piled high on crispy crackers. For a heartier meal, serve with fresh baguette slices or over a bed of arugula with microgreens. The possibilities are endless—don't be afraid to get creative!
