About this recipe

This grilled tuna Niçoise salad is loaded with so many delicious flavors. Be sure to serve the petite potatoes warm so the butter and spices do not harden on the potatoes. You can leave the mini potatoes whole or slice them in half. Just be sure to spread them in small clusters across the entire salad.

When prepping the tuna steak, make sure to pat it dry with a paper towel. Removing the excess moisture will prevent the tuna from cooking too quickly. Moisture acts as a heat conductor and if the tuna steak is too moist it will over cook. Drizzle it with olive oil right before you place it on the grill. It will only need 1.5-2 minutes per side. This will give you a rare temperature in the center of the tuna. Sushi grade ahi tuna is safe to eat rare.

Bring a pot of water to a boil and cook the eggs for 9-10 minutes. Run them under cold water to bring the temperature down. Peel the eggs and slice them in half. When dressing the salad, you can drizzle as much or as little dressing over the top as you like. Serve any extra dressing on the side.

This recipe makes four light servings. Please see below for the nutritional information.


Best of eaten the same day. Store any leftovers in an airtight container in the refrigerator for one maybe two days. The dressing can be stored covered in the refrigerator for 5 days. Looking for more delicious salad recipes? Try my Cobb salad with cilantro lime dressing or my grilled peach salad.

Prepare the tuna and lettuce:

  • Preheat the grill to 400 degrees. Be sure to wipe the racks with olive oil to help prevent the tuna steak and romaine lettuce from sticking. You can use foil if you prefer.
