Why You’ll Love This Version

This Nicoise Tuna Salad Recipe focuses on clean ingredients and straightforward technique. The dressing is emulsified by hand, so you don’t need a blender, and the green beans are blanched to keep their brilliant color and crisp-tender bite. Everything assembles quickly, and the salad can be scaled up for a crowd. The components are intentionally simple so each flavor—bright lemon, sharp Dijon, briny capers and Kalamata olives, and rich tuna—can stand out.

Ingredients

• 8 oz. fresh green beans
• 4 hard-boiled eggs
• 2 cups diced tomatoes (see notes)
• 1/2 cup Kalamata Olives (see notes)
• 1/4 cup drained capers
• 8 large radishes
• two 5 oz. cans tuna packed in olive oil (see notes)
• 1 T caper brine (from the jar)
• 2 T fresh-squeezed lemon juice
• 1/4 cup extra-virgin olive oil
• 1 T Dijon Mustard
• 1 tsp. minced garlic (see notes)
• 1 tsp. Spike Seasoning (optional, but good)
• 1/4 tsp. dried thyme
• salt and fresh ground pepper to taste (see notes)

Notes on Ingredients

• Tomatoes: Choose ripe but firm tomatoes for dicing so they hold their shape; plum or vine-ripened tomatoes work well. If your tomatoes are very juicy, drain them briefly over a sieve to avoid watering down the salad.
• Kalamata Olives: If you prefer a milder olive, use pitted, oil-cured black olives as an alternative, but the Kalamatas add a classic briny note that complements the tuna.
• Tuna: The cans specified are tuna packed in olive oil. Drain the oil lightly if you prefer a less oily finish, but leaving a little oil will add richness to the salad.
• Minced garlic: Use fresh garlic for the best flavor. If you need a milder garlic presence, mince the clove very finely or grate it on a microplane.
• Spike Seasoning: This is optional. If you don’t have it, a pinch of smoked paprika or a generous grind of black pepper makes a nice substitute.
• Salt and pepper: Taste the vinaigrette and the assembled salad and adjust seasonings at the end—capers and olives are salty, so you may need less added salt than usual.

Equipment

• Large pot for blanching
• Large bowl for ice bath
• Mixing bowl for dressing
• Large serving platter or salad bowl
• Sharp knife and cutting board
• Small sieve or measuring spoons

Prep Work (15–20 minutes)

Before you assemble the salad, do the basic prep so everything comes together quickly:

• Trim the ends off the 8 oz. fresh green beans and rinse them under cold water.
• Prepare an ice bath: fill a large bowl with ice and cold water.
• Peel and slice the 4 hard-boiled eggs in half or quarters, depending on how you like to present them.
• Dice 2 cups of tomatoes into bite-sized pieces; drain briefly if they are very juicy.
• Slice or halve 1/2 cup Kalamata Olives if they are whole and pitted.
• Drain 1/4 cup capers and set aside; reserve 1 tablespoon of the caper brine for the dressing.
• Thinly slice the 8 large radishes so they add crunch without overpowering.
• Open two 5 oz. cans tuna packed in olive oil and gently flake the tuna with a fork; drain a little oil if you prefer.
• Measure and ready the remaining dressing ingredients so you can whisk quickly: 1 tablespoon caper brine, 2 tablespoons fresh-squeezed lemon juice, 1/4 cup extra-virgin olive oil, 1 tablespoon Dijon mustard, 1 teaspoon minced garlic, 1 teaspoon Spike Seasoning (optional), 1/4 teaspoon dried thyme, salt and fresh ground pepper to taste.

Step-by-Step Instructions

The directions below follow the original ingredient order and have been rewritten for clarity and ease. Follow them in the sequence presented for best results.

1. Blanch the green beans

1. Bring a large pot of salted water to a rolling boil.
2. Add the 8 oz. fresh green beans and cook until they are crisp-tender and bright green, about 3 to 4 minutes depending on thickness.
3. Immediately transfer the green beans to the prepared ice bath using a slotted spoon or tongs to stop the cooking and lock in their color.
4. After a minute in the ice bath, drain the green beans well and pat them dry with a clean kitchen towel or paper towels.

2. Prepare the hard-boiled eggs and vegetables

1. Peel the 4 hard-boiled eggs and cut them in half lengthwise or into quarters. Set aside for plating.
2. Dice the 2 cups tomatoes and transfer to a small bowl; if they seem watery, let them sit in a sieve for a few minutes to drain excess juice.
3. Slice or halve the 1/2 cup Kalamata Olives and thinly slice the 8 large radishes. Keep these components separate so they are ready to arrange.

3. Flake the tuna and drain capers

1. Open the two 5 oz. cans tuna packed in olive oil and pour them into a bowl. Use a fork to gently flake the tuna into large, bite-sized pieces. Drain off excess oil if you prefer a lighter finish, but reserve a little oil for flavor.
2. Drain the 1/4 cup capers in a small sieve and give them a quick rinse if you want to reduce their saltiness. Reserve 1 tablespoon of the caper brine in a small bowl or measuring spoon for the dressing.

4. Make the lemon-Dijon vinaigrette

1. Add the reserved 1 tablespoon caper brine, 2 tablespoons fresh-squeezed lemon juice, 1 tablespoon Dijon mustard, and 1 teaspoon minced garlic to a medium mixing bowl.
2. Whisk the ingredients briefly to combine, then slowly pour in the 1/4 cup extra-virgin olive oil while whisking constantly to emulsify the dressing.
3. Stir in 1 teaspoon Spike Seasoning if using, and 1/4 teaspoon dried thyme. Taste and season with salt and fresh ground pepper to your preference—remember the olives and capers add saltiness, so go light and adjust later.

5. Assemble the salad

1. Choose a large serving platter or a shallow bowl to arrange the salad attractively.
2. Lay the blanched green beans in a neat pile or ring on the platter as a base component.
3. Scatter the diced tomatoes evenly across the platter, tucking them around the green beans.
4. Arrange the drained, flaked tuna in clusters across the salad so each portion will get some fish.
5. Distribute the sliced Kalamata Olives and drained capers across the salad for briny pops of flavor.
6. Place the hard-boiled egg halves or quarters strategically for visual appeal and easy serving.
7. Add the thinly sliced radishes for a peppery crunch, spreading them so every bite has a bright textural contrast.

6. Dress and finish

1. Lightly drizzle the lemon-Dijon vinaigrette over the assembled salad. Start with half the dressing and add more as needed so flavors balance without making the salad soggy.
2. Gently toss select sections with tongs if you want the dressing distributed, or leave the arrangement intact and serve the remaining dressing on the side for guests to add themselves.
3. Give the salad a final grind of fresh black pepper and a light sprinkle of salt only if needed after tasting a dressed bite.

Serving Suggestions

Serve this Nicoise Tuna Salad Recipe with crusty bread, a platter of mixed greens, or warm new potatoes on the side. For a full meal, pair it with a chilled glass of white wine or sparkling water with lemon. The salad holds up well for a few hours at cool room temperature, making it ideal for picnics or buffet-style service.

Storage and Make-Ahead Tips

• Make the dressing up to two days ahead and store it in a sealed jar in the refrigerator; shake well before using.
• Blanched green beans will keep in an airtight container for 2 days in the fridge; reheat briefly or serve cold.
• Assemble the salad just before serving for best texture, especially if your tomatoes are juicy or you expect the salad to sit for a while.
• Leftovers can be refrigerated in a covered container for up to 24 hours; the tuna and eggs will remain good but the vegetables may soften over time.

Variations and Swaps

If you want to tweak the salad, here are a few simple ideas while keeping the essential character intact:

• Add small boiled potatoes or fingerlings for a heartier plate.
• Swap radishes for thinly sliced cucumber for a milder crunch.
• Use green or Niçoise olives in place of Kalamatas for a slightly different olive profile.
• Stir a spoonful of capers into the flaked tuna for extra zing before assembling.
