Tuna Salad Sandwich
Ingredients
- 10 ounces canned tuna – drained
- 1/2 cups mayonnaise
- 1 tbsp lemon juice
- 1 tsp Dijon mustard
- 1/2 tsp kosher salt
- 1/2 tsp black pepper – freshly ground
- 1/2 cups celery – finely chopped
- 1/4 cups red onion – finely chopped (~0.5 medium red onions)
- 2 tbsp dill pickle relish
- 1 tbsp fresh parsley – chopped
- 8 slices sandwich bread
- lettuce leaves – for serving
- tomato – sliced (for serving)

Instructions
1. Drain the canned tuna well, pressing out excess liquid with the lid or a fork, 1–2 minutes.
2. In a medium bowl, whisk together the mayonnaise, lemon juice, Dijon mustard, kosher salt, and black pepper until smooth, 30 seconds.
3. Add the drained tuna, celery, red onion, dill pickle relish, and parsley. Fold until evenly combined but still slightly chunky, 30–60 seconds.
4. Taste and adjust seasoning with a pinch more salt, pepper, or lemon juice as needed. Chill the tuna salad for 10 minutes to meld flavors (optional but recommended).
5. Toast the sandwich bread slices to light golden brown, 2–3 minutes, or leave untoasted if preferred.
6. Assemble the sandwiches: Place lettuce leaves and tomato slices on 4 bread slices (if using). Divide the tuna salad evenly over the lettuce (about 0.5–0.75 cup per sandwich), then top with the remaining bread slices. Press gently, slice, and serve immediately.
A tuna salad sandwich pairs creamy, tangy tuna salad with soft or lightly toasted bread for a satisfying, savory bite. The filling typically balances rich mayonnaise with the crisp freshness of celery and onion, a zing of lemon, and a hint of mustard. Many enjoy the cool contrast of lettuce and tomato, which add texture and juiciness without overpowering the delicate tuna flavor.
Culturally, the tuna salad sandwich is a staple of American lunch counters and home kitchens, rising to prominence in the early 20th century alongside the widespread availability of canned tuna. As mayonnaise became a pantry standard, the combination quickly evolved into a convenient, protein-rich sandwich. Over time, regional tweaks appeared—some add relish or pickles for brightness, others fold in herbs or even hard-boiled egg—yet the essential character remains a creamy, crisp-edged tuna salad on bread.
