Ingredients You’ll Need
Gathering the right ingredients for this salad is a breeze, and each one plays an important role in creating the perfect mix of flavors and textures. From the creamy mayonnaise to the zingy pickle relish, every component is essential to give this dish its unique character and freshness.
- Tuna in water (2 cans, 5 ounces each): Provides a light but protein-rich base with a mild seafood flavor perfect for pairing with creamy elements.
- Mayonnaise (1/4 cup): Adds luscious creaminess and richness to bind everything together effortlessly.
- Dijon mustard (1 tablespoon, optional): Lends a subtle tang and depth, enhancing the salad’s flavor complexity without overwhelming.
- Celery stalk (1, finely chopped): Brings a refreshing crunch and a delicate vegetal note to balance the creaminess.
- Red onion (2 tablespoons, finely chopped): Introduces sharpness and a slight bite that cuts through the richness beautifully.
- Dill pickle relish (1 tablespoon): Injects bright acidity with a touch of sweetness, brightening up the entire salad.
- Lemon juice (1 teaspoon): Adds a fresh, citrusy tang to lift all the flavors and keep the salad vibrant.
- Salt and pepper (to taste): Essential seasoning elements that bring all the ingredients together in harmony.
- Chopped parsley (optional, for garnish): Offers a fresh herbal touch and a pop of green color for an inviting presentation.
How to Make Creamy Tuna Salad with Mayonnaise, Red Onion, and Dill Pickle Relish Recipe
Step 1: Combine Your Core Ingredients
Start by draining the tuna thoroughly to prevent excess liquid from making the salad watery. Place the tuna in a medium bowl, then add the mayonnaise, Dijon mustard if you’re using it, finely chopped celery, red onion, and dill pickle relish. The mixture of textures here—from creamy mayo to crisp celery—will create a wonderfully balanced base.
Step 2: Add the Bright Notes
Next, stir in the lemon juice, which will add a subtle zing to keep the salad lively and fresh tasting. This small addition truly makes a big difference, ensuring the salad never feels too heavy or flat.
Step 3: Season and Mix
Now season with salt and pepper to your liking. Take a moment to taste as you go here because the salt brings out the natural flavor of the tuna and the relish, while pepper adds a gentle warmth. Mix everything gently but thoroughly, aiming for a nicely creamy, evenly distributed salad.
Step 4: Chill and Serve
If you have time, chill the salad for 10 to 15 minutes in the fridge before serving. This allows the flavors to meld beautifully and the salad to firm up just a touch, making it even more delicious.
How to Serve Creamy Tuna Salad with Mayonnaise, Red Onion, and Dill Pickle Relish Recipe

Garnishes
Sprinkle freshly chopped parsley on top for a fresh, herbaceous aroma and a dash of vibrant green color. It’s a simple touch that can elevate your presentation without complicating your prep.
Side Dishes
Pair this creamy tuna salad with crusty artisan bread, crispy crackers, or even fresh lettuce leaves for a refreshing contrast in texture. A side of crunchy pickles or a fresh cucumber salad works beautifully here, amplifying the pickle relish’s flavors without overpowering the dish.
Creative Ways to Present
Beyond the classic sandwich or salad topping, try serving this tuna salad stuffed inside ripe avocado halves or bell pepper cups for an elegant, low-carb option. You can also make mini tartlets or spoon it onto cucumber slices for fun finger-food ideas perfect for gatherings or snacks.
Make Ahead and Storage
Storing Leftovers
This tuna salad keeps well in an airtight container in the refrigerator for up to 3 days. Keeping it chilled helps maintain the creamy texture and freshness of the ingredients. Always give it a good stir before serving leftovers.
Freezing
Freezing is not ideal for this salad because the mayonnaise and fresh vegetables can separate and become watery upon thawing. It’s best enjoyed fresh or within a few days of preparation for the best texture and flavor.
Reheating
This salad is best served cold or at room temperature. If you prefer a warmer dish, gently warm your bread or crackers to pair with the chilled tuna salad, but avoid heating the salad itself as it may lose its creamy consistency.
FAQs
Can I substitute Greek yogurt for mayonnaise?
Absolutely! You can replace half of the mayonnaise with Greek yogurt to lighten up the salad without sacrificing creaminess. It also adds a subtle tang and extra protein.
Is dill pickle relish necessary or can I omit it?
While you can omit it, the dill pickle relish adds an essential tangy sweetness that contrasts beautifully with the creamy mayo and savory tuna, so it’s worth including if possible.
What type of tuna is best for this recipe?
Albacore tuna offers a milder flavor and flaky texture, making it great for those who prefer a gentle tuna taste. Chunk light tuna has a stronger flavor and firmer bite if you want a more robust dish.
Can I add other mix-ins for extra texture?
Definitely! Chopped hard-boiled eggs, shredded carrots, or even diced apples make fantastic additions to bring more texture and flavor to this classic salad.
How long can I keep the salad in the fridge after making it?
For best taste and safety, consume the salad within 3 days when stored properly in the fridge. Beyond that, the texture and flavor may decline.
