Tuna Puff Pastry Pinwheels

Why we love this recipe:

The Tuna Pinwheels are simple to make, full of flavour and easily prepared from ingredients that I always have on hand. There are some culinary items that I feel are essential to always keep; canned tuna and frozen butter puff pastry are two of these items.

These Tuna Puff Pastry Pinwheels are ideal for:

When you're after a quickly prepared appetiser;
A savoury snack for the lunchbox;
Are preparing for entertaining and want to make things in advance.

When it comes to entertaining, I like to make my life as simple as possible, so I often turn to store-bought puff pastry. It is easy to use, so versatile and always popular. There are numerous ways in which to use it in either sweet or savoury dishes.

Ingredients in this recipe:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Frozen butter puff pastry - this is one ingredient that I don't make myself. For convenience, I always keep good quality butter puff pastry in the freezer.

Canned tuna - I use good quality tuna, packed in oil, as I feel that it has more flavour than tuna packed in water.

Brown onion - also known as a yellow onion, it is the one most commonly used. You could, however, substitute with a white onion.

Olive Oil - you could use a mild flavoured oil as an alternative if you prefer.

Cheddar cheese - also known as matured cheese or tasty cheese.

Continental/Italian parsley - this is the flat-leaf variety, and to me, the flavour and texture is far superior to curly parsley.

Lemon zest - adds a bright flavour. Be sure to avoid the bitter white pith.

Sea salt - is produced using natural methods of evaporation with minimal processing and this ensures that the salt retains much of its minerals.

Black pepper - freshly ground black pepper has brighter flavour than pre-ground.

Step by step instructions:

Steps 1-4 of preparing this recipe in a photo collage - the chopped onions in a pan, the cooked onions, breaking up the tuna, the ingredients together in a bowl.

Steps 5-8 of preparing this recipe in a photo collage - the mixture on pastry, starting to roll the pastry up, cutting the pinwheels and the pinwheels on a baking tray.

You will need to start by pre-heating your oven and removing a sheet of puff pastry from the freezer to defrost.

Finely chop some onion and add to a frying pan with a little olive oil.
Fry the oven until slightly caramelised, and set aside to cool.
Put drained tuna in a medium-size bowl and mash slightly to break up larger pieces.
Next, add the cooked onion, grated cheese, lemon zest and parsley to the tuna and mix well to combine. Season to taste with salt and pepper.
Top the sheet of puff pastry with the tuna mixture and spread it evenly. Using a spatula or the back of a spoon, press the mixture down to compact it.
Slowly start to roll the pastry from the end nearest you. Roll it forward, reasonably firmly, until you have come to the end of the roll. Place the filled pastry in the fridge for about 15 minutes to firm up before cutting.
Trim the ends with a serrated knife and discard. Then slice each pinwheel approximately 1.5cm (½ ") thick.
Place your Tuna Puff Pastry Pinwheels on a baking tray lined with non-stick baking paper and bake for 15-20 minutes, or until golden brown and cooked through.

Serve warm from the oven or cool to room temperature.

Tips for success and FAQs:

For the best result, pastry must always be kept cold. If the pastry thaws before you have made the filling, return it to the refrigerator until you are ready to use it.

When the pastry is almost defrosted, I add my filling and quickly roll up the pastry. To keep the pinwheel shape, it is essential that the pastry be rolled tightly.

I return the filled pastry to the fridge for about 15 minutes to firm up before cutting. A sharp, serrated knife is best for cleanly cutting the pastry.

Always pre-heat the oven. For the best rise, cold puff pastry must go into a hot oven.

Can the Tuna Puff Pastry Pinwheels be made ahead of time?

Yes, you can prepare them in advance. They are delicious served at room temperature on the same day they are made. Otherwise, we recommend that you reheat the pinwheels in a moderate oven just prior to serving to crisp the pastry.

How should I store the pinwheels?

Store them for up to four days in an airtight container in the refrigerator.

Can the pinwheels be frozen?

Yes, they can be frozen. After baking, allow them to cool completely then arrange them on a single layer on a baking tray and place in the freezer. When frozen, you can store them in an airtight container or zip-lock bag for up to two months. You can reheat them from frozen by placing in a pre-heated oven at 180 degrees C (350 F) for about 10 minutes.
