2. Preparing the Tuna Steaks
1. Choose High-Quality Tuna
- Look for sushi-grade or fresh tuna for the best flavor.
- The fish should be firm, deep red, and free from any strong odor.
2. Marinate the Tuna
- In a bowl, whisk together olive oil, Dijon mustard, lemon juice, garlic powder, paprika, salt, and black pepper.
- Coat the tuna steaks evenly and let them marinate for 10–15 minutes while you prep the salad.
3. Making the Niçoise Salad
1. Prepare the Vegetables
- Boil the baby potatoes until fork-tender (about 10 minutes), then halve them.
- Blanch the green beans in boiling water for 2 minutes, then plunge them into ice water to keep them crisp.
- Slice the cherry tomatoes, red onions, and olives.
- Peel and halve the hard-boiled eggs.
2. Assemble the Salad
- Arrange the greens on a large plate.
- Layer the potatoes, green beans, tomatoes, olives, red onions, and anchovies.
- Set the hard-boiled eggs around the edges.
4. Grilling the Tuna Steak
1. Heat the Grill or Pan
- Preheat your grill or grill pan over medium-high heat.
- Lightly oil the grill to prevent sticking.
2. Sear the Tuna
- Place the tuna steaks on the grill and sear for 1½–2 minutes per side for medium-rare.
- For well-done tuna, cook for 3–4 minutes per side, but avoid overcooking—it can become dry.
3. Rest the Tuna
- Remove from the grill and let it rest for 2–3 minutes before slicing.
5. Making the Lemon-Dijon Vinaigrette
1. Whisk the Ingredients
In a small bowl, whisk together:
- Olive oil, lemon juice, Dijon mustard, red wine vinegar, honey, garlic, salt, and black pepper.
2. Adjust the Flavor
- If it’s too tangy, add a bit more olive oil.
- If you prefer more acidity, increase the lemon juice or vinegar.
6. Plating & Presentation
1. Slice the Tuna
- Use a sharp knife to slice the tuna into thin strips.
2. Assemble the Dish
- Lay the grilled tuna slices on top of the Niçoise salad.
- Drizzle generously with the lemon-Dijon vinaigrette.
3. Garnish for Extra Elegance
- Sprinkle with fresh parsley or chives.
- Add a few extra olives for a finishing touch.
4. Wine Pairing Suggestions
- Sauvignon Blanc (light and citrusy, pairs well with vinaigrette).
- Rosé (refreshing, complements the briny olives and anchovies).
7. Common Mistakes & How to Avoid Them
1. Overcooking the Tuna
- Sear quickly for a tender, juicy texture.
- Medium-rare is best—overcooked tuna becomes dry and tough.
2. Dressing the Salad Too Early
- Wait until serving to drizzle the vinaigrette so the greens stay crisp.
3. Using Low-Quality Tuna
- Always choose fresh, high-quality tuna—the dish depends on it!
8. Storage & Reheating Tips
1. Storing Leftovers
- Store tuna and salad separately in airtight containers.
- Keep in the fridge for up to 2 days.
2. Best Way to Reheat
- Tuna: Serve cold or at room temperature for the best texture.
- Salad: Enjoy fresh; reheating may wilt the greens.

Grilled tuna steak with Niçoise salad & vinaigrette is a dish that’s light, flavorful, and full of Mediterranean charm. The perfectly seared tuna pairs beautifully with the crisp vegetables, briny olives, and tangy vinaigrette, creating a dish that’s both healthy and elegant.
