Tuna Toast with Tomatoes and Arugula is a simple Italian-inspired appetizer made with tuna, fresh tomatoes, arugula, and extra virgin olive oil, using the most quality ingredients you can find.

The secret to this tuna toast recipe is using good tuna and fresh tomatoes like our Pan Con Tomate recipe or our Grilled Romaine Bruschetta. We love making this in the summer and early fall during peak tomato season and is a nod to a regional dish from Puglia, Italy.

Tuna Toast Ingredients
As we said this is simple, Inspired by many trips to Italy. Because of so few ingredients it’s important to uses the freshest and best quality you can find.
- Great Bread – We prefer a baguette cut up in a bias to make crostini style tuna toast. If you want something larger, a como or sourdough loaf, cut into smaller slices is amazing. In Puglia they use a Frise or Friselle.
- Fresh Tomatoes – We recommend cherry or grape tomatoes. The reason we like fresh tomatoes is because they are fully ripened for the sweeter flavor. You can use this recipe all year long, but you may need to add some sweet components if the tomatoes are not sweet like aged balsamic vinegar.
- Arugula – The peppery and crip flavor of arugula is our favorite. But you can also use kale, finely diced, or any other crisp green you like.
- Canned Tuna – We prefer tuna that is packed in oil versus water. But look for a quality tinned or canned tuna.
- Olive Oil – There are many styles of olive oil to choose from. If you can find Arbequina olive oil, it has a fruiter vibrant flavor.
- Finishing Salt – A touch of Maldon or flaky finishing salt really elevates the tuna toast recipe. We use this as a magical finish whenever we cater on almost every recipe we make.
Preparation
For this tuna toast recipe, it’s all about making prep easy and having your mis en place (everything prepped) done before making them.
Make Crostini
Preheat your oven to 375 degrees Fahrenheit.
Cut your baguette or bread into thin slices on a bias (at an angle). Lay the slices of bread out on a sheet tray. We do not use parchment paper but you can if you want easier cleanup.
Brush olive oil on the top of the slices and cook them on the middle rack of the oven at 375 degrees Fahrenheit for 10 minutes or until golden.
Chef’s Tip
You can make the crostini for the tuna toast up to one day earlier. But when storing them, keep them in an airtight container away from light or they will get soft and stale. We do not recommend making them any more than 1 day prior.
Slice Tomatoes
Remove the stems if they have them and cut them in half. When selecting cherry tomatoes, they should be soft, but not squishy. That is a good indication of a sweet, ripe cherry tomato.
Drain Tuna
Place a paper towel on a plate or sheet tray. Remove the tuna from the oil and lay them out on the sheet tray. Some of the oil will naturally come off the tuna.
How To Make Tuna Toast
We recommend that you make the tuna toast on your serving platter for ease.
- In a medium size bowl add the tomatoes, tuna, and arugula. Drizzle with olive oil and use tongs to combine.
- Layer each crostini with pieces of the cherry tomatoes, crumbled tuna, and arugula.
- Top with a pinch of finishing salt and drizzle liberally with more extra virgin olive oil.
As a modification consider adding a flavored or aged balsamic vinegar.

Frequently Asked Questions
Tuna is high in protein and Omega 3 fatty acids, and also low in calories. Tuna in tin can also last for years in your pantry. Be sure to buy those packed in oil.

Wine Pairing
For tuna toast, the first thing we reach for is an Italian rosé. The acidity is a great complementing component to the tuna toasts. If you can’t find an Italian rosé then consider the pairing flavors with the good olive oil and tuna. Something like a Chardonnay or event an Oregon Pinot Noir.

Super easy and very delicious!
I love that tin of tuna! Definitely a happy fisherman. I make a version of this using chopped and deseeded ripe tomatoes mixed with a grated bulb of garlic and good olive oil. Mix it in to the tuna with a splash of vinegar, pink salt and coarse black pepper. Served on toasted sourdough with a wedge of lemon. I think Iโd like to try it with the bread you suggest x
