Ingredients for tuna stuffed deviled eggs

Twelve perfect eggs, flaky tuna, and crunchy celery—this is your new go-to appetizer.

The eggs are non-negotiable—use large eggs for consistent size, and room temperature ones peel easier. I always grab Kirkland Signature eggs from Costco—they're reliable for hard-boiling. For the tuna, high-quality in water is key—skip the oil-packed kind unless you love that flavor. The celery should be crisp, so buy it fresh and chop it just before mixing. Red onion adds that sharp bite that cuts through the creaminess, and I always grab the vibrant red kind from the grocery store produce section—it's prettier and holds up better.

No Dijon mustard? Yellow mustard at half the amount works in a pinch, but you'll lose that depth. Fresh lemon juice is ideal, but bottled lemon juice works too—just add a pinch more salt. The mayo can be light or regular, but avoid low-fat—it breaks down faster. For the celery topping, you can also use finely chopped green onion or chives if you're out. The paprika is just for color—skip it if you're going for a cleaner look, but I love that little pop of color on top. And if you're serving a crowd, double the batch—these disappear fast!

Hard-boiled eggs keep for 3 days in the fridge, but I like to make them fresh for this recipe. The filling mixture stays good for 2 days in the fridge, so prep ahead if you're hosting. For the celery topping, chop it right before serving to keep it crisp. Serve with lemon wedges on the side—they brighten up every bite. These taste even better the next day once the flavors meld, so make extras if you can. Store leftovers in an airtight container, but honestly, they rarely last that long!

Step-by-step instructions for tuna stuffed deviled eggs

Here's how to make these creamy, crunchy deviled eggs that'll have everyone asking for seconds.

Place the 12 whole Large Eggs in a saucepan and cover them with cold water by about 1 inch. Bring to a rolling boil over high heat, then immediately reduce to low heat and simmer for exactly 10 minutes. This timing gives you perfectly set whites with creamy yolks.

Transfer the eggs to an ice bath for 10 minutes to cool completely. Once cooled, peel the eggs carefully, making sure to keep the yolks intact. Crack each yolk into a small bowl and set aside. The whites should be completely dry—any moisture will make your filling too runny.

Finely chop the 0.5 cup Fresh Celery into tiny pieces—think ⅛-inch dice or smaller. You want it so fine it almost disappears when mixed in, creating that perfect textural contrast. In a small bowl, combine the chopped celery with the 2 tbsp Red Onion and 2 tbsp Chopped Parsley.

Give it a quick toss with 0.25 tsp Paprika and set aside. This celery mixture will add freshness and crunch that cuts through the richness of the filling. I like to mix it right before assembling so it stays crisp—no soggy celery here!

In a medium bowl, gently fold together the 1.5 cups Flaked Canned Tuna, 0.5 cup Mayonnaise, 1 tbsp Dijon Mustard, and 1 tbsp Lemon Juice. The tuna should be completely drained—any excess water will make your filling too thin. Use a fork to mix lightly, just until combined.

Season with 0.5 tsp Salt and 0.25 tsp Black Pepper. The Dijon mustard adds that perfect tangy depth, while the lemon juice brightens everything up. Taste it now—you want it flavorful but not overpowering. This is your base, so don't skimp on seasoning.

Carefully slice each egg white in half lengthwise. Using a small spoon, gently remove about 1 teaspoon of yolk from each half and place it in the bowl with the reserved yolks. The yolks should be smooth and intact—no breaking them up yet. You're creating room for that creamy filling!

Now, pipe or spoon the tuna mixture into each egg white half, filling them almost to the top. Then, using a small spoon, gently mash the reserved yolks with a fork until just combined. Spoon this yolk mixture over the tuna filling, creating that classic deviled egg look.

Sprinkle the celery-onion-parsley mixture evenly over each deviled egg half. The celery should be distributed so every bite has that fresh crunch. For extra flair, garnish each egg with a pinch of paprika on top of the celery.

Serve immediately with the 4 whole Lemon Wedges on the side. The contrast of creamy filling, crunchy celery, and bright lemon is what makes these deviled eggs truly special. They're perfect for parties, picnics, or just a fancy snack—everyone will think you spent hours in the kitchen!

Common mistakes when making this dish

Overcooking Eggs

I’ve ruined more deviled eggs than I’d like to admit by overcooking the yolks. When hard-boiling, 10 minutes of simmering is perfect—any longer and the yolks turn green and chalky. I’ve learned to set a timer and watch the water like a hawk.

If you’re worried about consistency, try the ice bath trick immediately after boiling to stop the cooking process. 💛

Skipping the Ice Bath

Skipping the ice bath is a rookie mistake that leads to peeling nightmares. Eggs left to cool at room temperature develop a stubborn membrane that makes peeling nearly impossible.

I now make it a rule to shock my eggs in ice water for 10 minutes—it’s the only way to guarantee clean peels and intact yolks. Pro tip: Use your fingers to gently roll the eggs on a cutting board while peeling for extra help.

Using Low-Quality Tuna

Not all tuna is created equal, and cheap brands with oil or excess water can ruin your filling. I always reach for high-quality water-packed tuna like Wild Planet or Vital Choice—they drain perfectly and have the best texture.

If your tuna is watery, drain it thoroughly and pat it dry with a paper towel before mixing. Trust me, the difference is noticeable.

Overmixing the Filling

Gently folding the tuna mixture is key—overmixing makes it dense and dry. I use a fork to combine everything just until the tuna is evenly distributed. If your filling looks grainy or dry, add 1 teaspoon of mayo to loosen it up.

The goal is a smooth, creamy texture that holds its shape when piped into the egg whites. 🥚

Not Drying the Egg Whites

Moisture is the enemy of stable deviled eggs. After peeling, I always pat the egg whites dry with a paper towel to remove any excess moisture. This prevents the filling from sliding out or making a mess.

If your whites feel damp, let them sit uncovered for 5 minutes before assembling—the extra drying time makes all the difference.

Underseasoning the Filling

Tuna filling can taste bland if you’re not careful. I always taste the mixture before assembling and adjust the seasoning—usually adding a pinch more salt or lemon juice. The Dijon mustard adds depth, but if you’re using regular mustard, add an extra ½ teaspoon of salt to compensate.

A well-seasoned filling is the secret to deviled eggs that taste restaurant-quality. 🌶️
