Ingredients for Tarte au Thon et Tomate

For the Crust:

Shortcrust Pastry (1 sheet, store-bought or homemade) – The base of our tart. If making from scratch, use butter for a rich, flaky texture.

For the Filling:

Canned Tuna (2 cans, drained) – Tuna packed in olive oil is best for maximum flavor, but water-packed works too.
Tomatoes (2-3 medium, sliced thinly) – Use ripe, juicy tomatoes for the best taste. Roma or heirloom varieties work well.
Dijon Mustard (2 tablespoons) – A classic French touch that adds depth and a bit of tangy spice.
Crème Fraîche or Heavy Cream (½ cup) – Makes the tart rich and creamy. Greek yogurt can be used for a lighter option.
Eggs (2 large) – Helps bind the filling together.
Grated Cheese (½ cup, Gruyère or Emmental) – Adds a touch of saltiness and a golden, cheesy top.
Salt & Black Pepper (to taste) – Enhances all the flavors.
Herbes de Provence (1 teaspoon, optional) – A blend of thyme, oregano, and rosemary gives a nice Mediterranean touch.
Olive Oil (1 tablespoon) – For drizzling over the tomatoes before baking.

How to Make Tarte au Thon et Tomate

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). If using a homemade crust, roll it out and fit it into a tart pan. Prick the bottom with a fork to prevent bubbling.

Step 2: Prepare the Tart Base

Spread a thin layer of Dijon mustard over the bottom of the tart crust. This not only adds flavor but also creates a barrier to prevent the crust from getting soggy.

Step 3: Mix the Tuna Filling

In a bowl, whisk together the eggs, crème fraîche (or heavy cream), grated cheese, salt, pepper, and Herbes de Provence. Then, gently fold in the drained tuna, breaking it up slightly but leaving some texture.

Step 4: Assemble the Tart

Pour the tuna mixture over the prepared crust. Arrange the tomato slices on top in an overlapping circular pattern. Drizzle with a little olive oil and a sprinkle of extra salt and pepper.

Step 5: Bake

Place the tart in the oven and bake for 30-35 minutes, or until the top is golden brown and the filling is set. The tomatoes should be slightly caramelized, and the crust should be crisp.

Step 6: Serve and Enjoy!

Let the tart cool for about 10 minutes before slicing. Serve warm or at room temperature with a side salad and a glass of chilled white wine for a true French bistro experience!

Equipment Needed

Tart Pan (9-inch) – To shape the tart perfectly.
Mixing Bowl – For combining the filling ingredients.

Knife and Cutting Board – For slicing the tomatoes.
Oven – To bake the tart to perfection.

Frequently Asked Questions

Can I use puff pastry instead of shortcrust pastry?

Yes! Puff pastry will give the tart a flakier, lighter texture. Just be sure to bake it until the bottom is fully crisp to avoid sogginess.

What kind of cheese works best for this tart?

Gruyère, Emmental, or Comté are the best choices, as they melt beautifully and complement the tuna and tomatoes. If you prefer a milder taste, mozzarella works too.

Can I add other vegetables?

Absolutely! You can add sliced zucchini, caramelized onions, or even roasted red peppers for extra flavor. Just be careful not to add too much moisture.

How do I store leftovers?

Store any leftover tart in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for 10 minutes to crisp it up again.

Is this tart good for meal prep?

Yes! It keeps well in the fridge and can be enjoyed warm or cold, making it a great option for lunches or light dinners throughout the week.

What can I serve with this tart?

A fresh green salad with a simple vinaigrette, a bowl of soup, or roasted potatoes all pair wonderfully with this tart.

Can I make it ahead of time?

Yes! You can fully bake the tart ahead of time and store it in the fridge. Reheat it briefly in the oven before serving to refresh the flavors.
