How this recipe comes together

What you’ll need
- 2 cans 12 oz cans of tuna, drained
- 2 stalks chopped celery
- 3 tablespoons dill relish
- 1-2 boiled eggs
- 1/2 cup mayo
- 1 tablespoon dijon mustard

- Tuna: Use any canned tuna, including white or light.
- Celery: For a different crunch, try diced bell pepper.
- Mayo: Greek yogurt can be a low-calorie substitute if you prefer lighter options.
- Dill Relish: This adds a tangy flavor, but if you don’t have it, finely chopped pickles work too.
How to make it
- Drain the cans of tuna and place the tuna in a mixing bowl.
- Chop the celery and boiled eggs, then toss both into the bowl along with the dill relish.
- Add in the mayo, dijon mustard, lemon juice, salt, and pepper.
- Mix everything until fully combined, and taste to check if you’d like to adjust flavors.
- Serve immediately or cover and refrigerate to let the flavors meld. The salad is good for up to 3-4 days in the fridge.
Pro Tip: If you used less tuna, you might want to taste and adjust the mayo and seasoning accordingly.
Visual cues: You’ll see a creamy, cohesive mixture with bright specks of celery and egg throughout.
Extra advice
- Incorporate a squeeze of fresh lemon for an extra zing.
- Ensure your ingredients are at room temperature for the best mixing.
- Consider using a hand mixer for an ultra-smooth salad if you prefer that texture.
How to plate & pair
This tuna salad shines when served chilled, perhaps over a bed of greens or sandwiched between slices of whole grain bread. You can elevate the presentation by garnishing with a sprig of dill or a slice of lemon. Pair it with cucumber slices or carrot sticks on the side for a refreshing crunch.
How to store & freeze
Tuna salad can be kept in an airtight container in the refrigerator for 3-4 days. To maintain the best quality, consume it within this time frame. Avoid freezing the salad; the texture may suffer upon thawing, causing veggies to become mushy.
“Refrigerate leftovers within 2 hours; reheat until steaming hot.”
Fixes for common issues
- If it’s too dry: Add a little more mayo or a splash of lemon juice to bring moisture back.
- If it tastes bland: A pinch of salt or additional dill relish can enhance the flavor dramatically.
- If it’s too salty: Add a bit more tuna or extra mayo to balance out the saltiness.
Creative twists
- For a spicy kick, try adding diced jalapeños or a dash of hot sauce to your salad.
- Incorporate crushed nuts like almonds or pecans for additional crunch and flavor.
- Swap some of the mayo for avocado for a creamy, nutrient-dense alternative.
