This Creamy Tuna and Sweet Corn Puff Pastry Jalousie is the ultimate easy, impressive meal. A no-cook filling of tuna, sweet corn, and cheese is wrapped in flaky puff pastry and baked until golden. Perfect for a quick dinner, picnic, or party food.
Preheat oven to 200°C (180°C fan). In a bowl, mix drained tuna, drained corn, diced onion, grated cheese, mayonnaise, parsley, salt, and pepper until combined.
ASSEMBLE BASE
Place two halves of the partially thawed puff pastry sheets on a lined baking tray. Divide the filling between them, spreading evenly and leaving a 2cm border.
CREATE TOP LAYER
With the remaining pastry halves, cut parallel slits lengthways at 1.5cm intervals, leaving a 2cm solid border uncut on all sides.
SEAL & FINISH
Drape the slashed pastry over the filling. Press edges to seal and crimp with a fork. Brush the top with beaten egg yolk and sprinkle with sesame seeds (if using).
BAKE
Bake for 30-35 minutes until the pastry is puffed and deep golden brown. Let rest for 5-10 minutes before slicing. Serve as desired.
Notes
COOKS NOTES: Oven Temps: Oven temperatures are for conventional, if using fan-forced (convection), reduce the temperature by 20˚C. Measurements: We use Australian tablespoons and cups: 1 teaspoon = 5 ml, 1 tablespoon = 20 ml & 1 cup = 250 ml. Herbs: All herbs are fresh (unless specified) and cups are lightly packed. Vegetables: All vegetables are medium size and peeled, unless specified. Eggs: We use extra-large size and eggs are 55-60 g each, unless specified.
Puff Pastry: Thaw sheets in the fridge until just pliable but still cold. If they become too soft and sticky, refrigerate for 10 minutes to firm up.
Egg Wash: Using just the egg yolk gives a richer golden colour. A whole beaten egg can also be used.
Make Ahead: Assemble completely, cover, and refrigerate for up to 8 hours before baking. Or freeze unbaked; bake from frozen, adding 10-15 minutes to the time.
Serving: Best served warm or at room temperature. Leftovers reheat well in a warm oven to crisp the pastry.
