Tuna Salad Recipe with Egg Mayo and Relish: Protein-Packed Creamy Crunch

This protein-packed tuna salad delivers creamy texture with a satisfying crunch from fresh vegetables and relish. I developed this version to elevate the classic deli staple into something worth making at home.

The secret is hard-boiled eggs, which add richness and help bind the salad without extra mayo. Fresh celery and relish provide brightness and texture, while a squeeze of lemon keeps it from tasting flat.

What you get is a versatile dish that works in sandwiches, on crackers, or straight from the bowl. The egg makes it heartier than traditional versions, turning it into a complete meal rather than just a side.

Perfect for meal prep—it actually improves after a night in the fridge. Here’s how to make it.

Ingredients for Tuna Salad Recipe with Egg Mayo and Relish

Pantry staples plus a few fresh additions create this satisfying dish with creamy texture and crunch.

The tuna matters here. Wild-caught in water (not oil) keeps it light and lets the other flavors shine. I grab mine from Trader Joe’s or Whole Foods—their brands are consistently good. Hard-boiled eggs from the store work (the pre-peeled kind), but freshly boiled taste better and hold their shape. The celery should be crisp, not limp—look for bright green stalks with tight leaves.

No relish? Diced pickles plus a teaspoon of sugar gets you close. Greek yogurt can replace mayo at a 1:1 ratio if you want it lighter. Out of celery? Cucumber or bell pepper adds a similar crunch. The lemon juice is non-negotiable though—it cuts through the richness. If all you have is lime, that works too (trust me on this).

This keeps beautifully for 3-4 days in the fridge—actually tastes better after a night. Don’t freeze though; the eggs get weird. Store in an airtight container (I reuse pasta sauce jars). Perfect for meal prep lunches all week long.

Step-by-Step Instructions for Tuna Salad with Egg, Mayo, and Relish

This method ensures a creamy, well-balanced salad with the perfect crunch and texture.

Step 1: Drain and Flake the Tuna

Open the 2 cans Canned Tuna in Water and drain them thoroughly in a fine-mesh strainer. Press gently with a spoon to remove all excess liquid—this prevents a watery salad.

Transfer the drained tuna to a large mixing bowl and use a fork to flake it into fine, even pieces. I like to break it up completely so every bite has the same texture. This step takes about 2 minutes and ensures the tuna blends evenly with the other ingredients.

Step 2: Chop and Prepare the Vegetables

Finely dice the 2 whole Celery Stalks and mince the 0.25 cup Red Onion. I use a sharp chef’s knife for this to get clean, uniform pieces. The celery should be small enough to distribute evenly but still provide a satisfying crunch.

Chop the 4 whole Hard-Boiled Eggs into small pieces—about ¼-inch cubes. This size ensures they blend well without disappearing into the mix. Chop the 2 tbsp Fresh Dill as well, if using. Set all chopped ingredients aside in a small bowl for easy adding later.

Step 3: Mix the Creamy Dressing Base

In a separate small bowl, whisk together the 0.5 cup Mayonnaise, 3 tbsp Sweet Relish, 1 tbsp Fresh Lemon Juice, 1 tsp Dijon Mustard, 0.5 tsp Salt, and 0.25 tsp Black Pepper until smooth.

The mixture should look creamy with small flecks of relish. Taste and adjust seasoning if needed—this is your chance to balance the flavors before combining everything. The lemon juice brightens the richness of the mayonnaise, while the mustard adds a subtle depth.

Step 4: Combine All Ingredients Gently

Pour the dressing over the flaked tuna in the large bowl. Add the chopped celery, red onion, hard-boiled eggs, and fresh dill. Use a silicone spatula or large spoon to fold everything together gently—this keeps the ingredients intact while ensuring even distribution.

Mix just until combined, about 1-2 minutes. Overmixing can break down the eggs and tuna too much, leading to a mushy texture. The salad should look creamy with visible chunks of egg, celery, and tuna throughout.

Step 5: Chill and Finish with Paprika

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to let the flavors meld. This chilling time is crucial—it allows the tuna to absorb the dressing and the flavors to develop fully.

Just before serving, sprinkle the 0.25 tsp Paprika evenly over the top and give it one final gentle stir. This adds a subtle warmth and a beautiful pop of color. Serve chilled for the best texture and flavor.

Make-Ahead Tips for This Dish

Prep Ahead Strategy

Hard-boil your eggs up to 3 days in advance—they peel easier when cold and stay fresh in a sealed container. I like to make a big batch of 6-8 eggs at once so I have extras for snacks. Use a timer for perfect 12-minute eggs with firm yolks. 💡

Chop Vegetables Early

Dice the celery and mince the onion the night before, storing them in separate airtight containers with a damp paper towel to maintain crispness. This saves 10 minutes on prep day. The flavors actually intensify overnight, making your salad taste even better.

Dressing Pre-Mix

Whisk together the mayo, relish, lemon juice, and mustard up to 2 days ahead. Store in a small jar in the fridge. Give it a quick stir before combining with the other ingredients to redistribute the relish and spices evenly.

Assemble the Day Before

Combine all ingredients except the paprika and mix gently. Refrigerate overnight in a glass container with a tight lid. The flavors meld beautifully, and the celery stays crisp. Add the paprika just before serving for the freshest presentation. ⏰

Portion for Convenience

Divide the finished salad into individual serving containers for grab-and-go lunches. Use 8-ounce mason jars or small Tupperware. It stays fresh for 3-4 days in the fridge, making it perfect for weekly meal prep.

Revive if Needed

If the salad seems dry after storage, stir in 1-2 tablespoons of mayo or a splash of lemon juice. This restores the creamy texture without overpowering the original flavors. Always taste and adjust seasoning after adding extra ingredients.
