Ingredients

Tuna marinade

• 8 ounces fresh sushi-grade ahi tuna
• 1 lemon
• 1 lime
• 1 small orange
• 2 sprigs rosemary
• 2 tablespoons olive oil

White wine vinaigrette

• 2 tablespoons white wine vinegar
• ½ tablespoon dijon mustard
• ½ teaspoon lemon zest
• 1 tablespoon balsamic vinegar
• ½ teaspoon white sugar
• 1 garlic minced
• ⅓ cup olive oil
• salt and pepper

Salad

• ½ cup fingerling potatoes
• 1 tablespoon olive oil
• 2 large eggs
• 1 cup green beans
• ½ cup cherry tomatoes
• ¼ cup kalamata olives
• 2 tablespoons capers
• 5 cups mesclun greens

Instructions

• Peel lemon, lime, and orange. Reserve peels and save fruit for another time. Season tuna with salt and pepper on both sides. Combine with citrus peels, rosemary and olive oil in a Ziploc plastic bag. Marinate overnight.
• Preheat oven to 400 degrees F.
• Make the dressing. Mix together white wine vinegar, dijon mustard, lemon zest, balsamic vinegar, sugar, and garlic in a medium bowl. Slowly whisk in the olive oil until thickened. Season with salt and pepper.
• Cut fingerling potatoes in half. Season the potatoes with salt and pepper and toss with 1 tablespoon oil. Spread the potatoes on a baking sheet and roast for 20-25 minutes or until tender. Remove from the oven and let cool.
• Place eggs in a medium pot and cover with water. Bring to a rapid boil over high heat. Turn off the heat and let the eggs sit in the hot water for 8 minutes. Drain and place eggs in an ice bath to stop the cooking process. Peel eggs and cut in half.
• Bring a medium pot of salted water to a boil. Add the green beans and blanch for 2-3 minutes or until crisp-tender. Remove from heat, drain and immediately shock in an ice bath until cool.
• Remove the tuna from the marinade, discarding the aromatics. Heat 1 tablespoon of oil in a skillet or cast iron pan over high heat until hot. Sear the tuna for 2 minutes on each side for medium rare. Remove the tuna from the pan and let rest for 5 minutes. Slice into ½-inch slices.
• Toss together mesclun greens with the potatoes, egg, green beans, tomatoes, olives, and capers. Divide onto two plates. Top with seared ahi tuna and drizzle vinaigrette on top. Serve immediately.

Notes

Use high quality sushi-grade tuna for the seared ahi tuna.

The white wine vinaigrette as well as all of the components can be prepared ahead of time, making this salad great for meal plan.

Step-by-step instructions

Step 1: Marinate tuna

Nicoise salads are traditionally very lightly seasoned with a simple vinaigrette. This doesn't mean that it can't be flavorful as well!

Let's start incorporating flavor with the main protein, the tuna. Marinate the ahi tuna in herbs and lemon, orange, and lime zest to give it a nice citrus flavor.

When I was working as a line cook at a seafood restaurant, we used a similar marinade, so you know it's a winning dish!

If you want to speed up the process, you can vacuum-seal the tuna and let it sit for 4 hours.

Step 2: Prepare remaining ingredients

Meanwhile, prepare the remaining salad ingredients. For the salad dressing, we're making a simple but delicious white wine vinaigrette. The traditional salad uses red wine vinegar, but I love the sweetness of white wine vinegar. Adding balsamic vinegar also amps up the sweetness while adding another layer of flavor.

Slice fingerling potatoes in half and roast them in the oven for 20-25 minutes or until tender. You can also boil the potatoes, but roasting gives them a great crispy exterior.

Test if the potatoes are ready by poking them with a fork. The fork should easily pierce the potato when they are ready; hence the phrase "fork-tender"!

Boil a couple of eggs and blanch green beans until crisp-tender. Halve cherry tomatoes, slice olives, and set aside the capers for the remaining components.

If you're making this Nicoise salad for meal prep, you can prepare all of these ingredients ahead of time and assemble the salads. However, I recommend storing the tuna separately.

Step 3: Cook tuna

Now let's turn our attention back to the tuna. Remove the tuna from the marinade, discarding the citrus peels and rosemary.

Heat a large saute pan and carefully lay the tuna in the pan. When searing the tuna, make sure your pan is hot, and when I mean hot, I mean HOT! You want to create a nice crust on the outside, but still keep a pink interior.

I like my tuna more on the rare side, so I only sear it for one minute on each side. That's why it's important to buy sushi-grade tuna to avoid the risk of bacteria from eating unclean fish.

Remove the fish from the pan as soon as it's done searing. If you let it rest on the pan, it will continue to cook.

Transfer it to a plate and let it rest for 5 minutes before slicing.

Step 4: Assemble salads

We've finally come to the finish line! Assemble your seared ahi tuna nicoise salad, portioning the mesclun greens into two plates. Top the greens with roasted potatoes, kalamata olives, heirloom cherry tomatoes, green beans, and a boiled egg. Toss everything in the white wine vinaigrette and dig in!

It's amazing how a simple change, such as adding seared ahi tuna, can make such a huge difference. The tuna adds substance to the dish while still tasting fresh and healthy. Easy on the waist and oh-so-tasty, what more can you ask for?

Make-ahead and storage

• Make-ahead: All of the components for the salad, excluding the tuna, can be prepared ahead of time. It's best to cook the tuna right before serving since it is raw fish.
• Store: If preparing this salad for meal prep, assemble the salads and store the tuna and salad dressing in a separate container. Hold in the refrigerator for up to 2 days.
