Ingredients You’ll Need

The beauty of La Tarte au Thon (Tuna Quiche) lies in the freshness and simplicity of its ingredients. Each component doesn’t just pull its weight in terms of flavor and texture—it brings that certain French magic you adore in a great lunchtime quiche.

9” Pie Crust: The foundation of the dish; choose store-bought for ease or homemade for an ultra-buttery finish.
2 Cans Chunk Light Tuna in Oil: Opt for tuna packed in oil for richer flavor and moistness; skip the albacore for this quiche.
3 Oven Dried Tomatoes, Chopped: These add sweetness and color; roasted red peppers or sundried tomatoes also work beautifully.
3/4 Cup Swiss or Gruyere Cheese, Grated: Melts into the filling for a nutty, savory note and luscious texture.
4 Eggs: The backbone of any quiche; eggs set the custard and create that fluffy, tall filling.
1 Tsp Piment d’Espelette (or Smoked Paprika/Pimenton): This Basque pepper provides subtle warmth and authenticity—smoked paprika is a great substitute.
1 Cup Creme Fraiche (7 oz container): For creamy richness; if unavailable, use a mix of sour cream and heavy cream.
1 Tbsp Dijon Mustard: Brush the crust for a tangy, aromatic kick.
Pinch of Thyme or Chopped Chives: Whisk in herbal brightness and color.
Salt & Black Pepper: Essential for balancing and enhancing all the flavors.

How to Make La Tarte au Thon (Tuna Quiche)

Step 1: Prepare Your Crust

Start by making or thawing your pie crust of choice. Place it into a 9-inch tart or pie pan, pressing gently into the edges for even coverage. If you’re feeling extra, try a layer of puff pastry for a golden, flaky bite. Preheat your oven to 350F so everything’s ready when you are.

Step 2: Add the Dijon Kick

Grab your tablespoon of Dijon mustard and, using a pastry brush or the back of a spoon, spread a thin, even layer right over the base of the prepared crust. This secret step gives La Tarte au Thon (Tuna Quiche) its signature depth—think subtle tang that sets off the creamy filling to come.

Step 3: Mix the Filling

In a large bowl, combine the drained tuna (it should flake easily), chopped oven dried tomatoes, and grated cheese. Add in the eggs, creme fraiche, piment d’Espelette or smoked paprika, and a pinch of thyme or chives. Season well with salt and black pepper. Stir everything together until you have a lush, well-combined filling bursting with color and aroma.

Step 4: Assemble the Quiche

Pour the filling into your mustard-brushed crust, using a spatula to spread it evenly all the way to the edges. Take a peek—is each bite packed with creamy custard, cheese, and savory fish? That’s exactly what you want! The filling should reach just below the rim, baking up beautifully tall.

Step 5: Bake Until Golden

Slide your quiche into the preheated 350F oven and bake for 35-40 minutes. You’re looking for a golden, gently puffed top and a slight wobble in the center. Let it cool for at least 10 minutes before slicing—if you can resist!

How to Serve La Tarte au Thon (Tuna Quiche)

Garnishes

A sprinkle of fresh chives or thyme gives your La Tarte au Thon (Tuna Quiche) a pop of green and a fragrant lift. I also love a few twists of black pepper and a drizzle of good olive oil right before serving. For a Parisian café feel, include a lemon wedge on the side.

Side Dishes

This quiche begs for a crisp, lightly dressed green salad. Toss arugula or frisée with lemon vinaigrette to slice through the rich filling. A handful of olives, a few slices of ripe avocado, or a scoop of tangy carrot salad make for a spread worthy of a French bistro lunch.

Creative Ways to Present

Individual slices are classic, but you can bake La Tarte au Thon (Tuna Quiche) in mini tart shells for adorable party bites. Pair with petite pickled vegetables or arrange on a brunch board with assorted cheeses and rustic bread. For a spring gathering, I love serving it in picnic-style wedges, tucked alongside fresh fruit and sparkling water.

Make Ahead and Storage

Storing Leftovers

Wrap cooled slices of La Tarte au Thon (Tuna Quiche) tightly in plastic wrap or store them in an airtight container. Pop them in the refrigerator where they’ll keep for up to three days, making lunch or a quick snack super easy.

Freezing

For longer-term storage, you can freeze the quiche in whole or in slices. Wrap well with plastic and foil to prevent freezer burn. It will keep beautifully for up to two months—just remember to thaw overnight in the fridge before reheating.

Reheating

To bring back that freshly-baked flavor, reheat slices in a 325F oven for about 10 minutes or until warmed through. This keeps the crust crisp and the filling creamy, just like the day you baked it. Avoid the microwave if you can; the oven really is worth it!

FAQs

Can I use a different type of cheese?

Absolutely! While Swiss and Gruyere are traditional for La Tarte au Thon (Tuna Quiche), feel free to swap in Emmental, sharp cheddar, or even a mix if that’s what you have on hand. Each cheese brings its own unique flavor and meltiness, so have fun experimenting.

Is there a good gluten-free crust option?

Yes, there are many gluten-free pie crusts available in stores, or you can make your own using a blend of almond or oat flour and butter. Even puff pastry has gluten-free versions on the market now, so La Tarte au Thon (Tuna Quiche) can work for nearly everyone!

What if I can’t find creme fraiche?

No worries. A combination of half sour cream and half heavy cream makes a solid substitute for creme fraiche in this recipe. The texture and tang will be just right for the creamy custard base in your tuna quiche.

Can I serve this dish cold?

Yes! In fact, La Tarte au Thon (Tuna Quiche) is delicious at room temperature or even slightly chilled. It’s perfect for picnics, potlucks, or make-ahead lunches. The flavors become even more pronounced as it cools.

How do I know when the quiche is done baking?

The top should be golden, lightly puffed, and the center just set with a very slight wobble. Insert a knife near the center—if it comes out mostly clean (a little moisture is okay), your La Tarte au Thon (Tuna Quiche) is ready to come out of the oven.

I promise, it’s as satisfying as it is easy—and will quickly become a new favorite for cozy lunches, picnics, or anytime you need a touch of Paris at home!
