How to Make La tarte au thon – The tuna tart
Step 1: Preheat and Prepare Your Pastry
Start by preheating your oven to 180ºC. Lay your ready-rolled puff pastry over baking paper if it isn’t already, and gently line your tart tin with it. Use a fork to prick the base all over—this prevents the pastry from puffing up excessively, ensuring a crisp and even crust for your La tarte au thon – The tuna tart.
Step 2: Layer on the Mustard
Spoon the wholegrain mustard into the lined pastry base and use the back of the spoon to spread it evenly to the edges. This layer infuses every bite with gentle heat and depth, acting as a perfect foil to the tuna and creamy filling.
Step 3: Mix and Add the Creamy Tuna Filling
In a medium bowl, combine the crème fraîche, drained tuna, and shredded emmental cheese. Stir well to create a rich, smooth filling. Once combined, pour and gently spread this mixture over the mustard-lined pastry shell.
Step 4: Arrange the Tomatoes
Slice your tomatoes thinly and lay them over the creamy mixture. The vibrant rounds not only look beautiful but will also roast into sweet, jammy jewels as the tart bakes—making your La tarte au thon – The tuna tart irresistibly inviting.
Step 5: Bake to Golden Perfection
Transfer the tart to your preheated oven and bake for about 35 minutes, or until the pastry edges are firm and gloriously golden. The top should bubble gently and the whole kitchen will fill with a savory, mouthwatering aroma. Serve the tart warm, straight from the oven for the best experience.
