Behind the Recipe

This recipe was born on a rainy afternoon when I needed something hearty and comforting, but not too heavy.

What started as a random kitchen experiment turned into one of those unexpectedly perfect creations. Since then, these pastries have been a go-to for lazy lunches, last-minute guests, or cozy Sunday snacks.

Recipe Origin or Trivia

Halloumi, the star of this recipe, hails from Cyprus and has become beloved for its squeaky texture and high melting point, making it perfect for frying or baking. Pairing it with caramelised onions is a classic Mediterranean move—balancing salty and sweet, chewy and soft. Pastry-wrapped snacks like these can be found in various cultures, from Greek tiropita to Middle Eastern börek, each with their own twist on savory fillings wrapped in dough.

Ingredients in Halloumi & Caramelised Onion Pastries

What makes this dish truly sing is the balance between the rich, savory, and subtly sweet elements. Here’s what you’ll need:

1. Puff Pastry Sheets: 2 sheets, thawed if frozen. This forms the crisp, golden outer shell.
2. Halloumi Cheese: 200g, grated or crumbled. Adds a salty, chewy contrast.
3. Brown Onions: 2 large, thinly sliced. Their sweetness deepens when caramelised.
4. Olive Oil: 1 tablespoon. Helps soften and brown the onions.
5. Butter: 1 tablespoon. Adds richness and helps with caramelisation.
6. Fresh Thyme (optional): 1 teaspoon, leaves only. Adds a subtle herbal note.
7. Salt and Pepper: To taste. Enhances flavor.
8. Egg: 1, beaten. Used to seal and glaze the pastries for a golden finish.

Ingredient Substitutions

Don’t worry if you’re missing something, here’s how to make it work:

Halloumi Cheese: Feta or mozzarella chunks (though softer in texture).

Brown Onions: Red onions or shallots work just as well.

Puff Pastry: Use filo pastry layers with brushed butter between.

Olive Oil: Sunflower or vegetable oil in a pinch.

Fresh Thyme: Use dried thyme or skip entirely.

Ingredient Spotlight

Halloumi: A firm, brined cheese that doesn’t melt, making it ideal for baking. Its saltiness balances beautifully with sweet onions.

Brown Onions: When caramelised, they become rich and sweet, almost jam-like, adding depth to the pastry filling.

Instructions for Making Halloumi & Caramelised Onion Pastries

Now let’s get into the step-by-step of how you’ll bring these beauties to life. Trust me, the smell alone while baking is worth it.

1. Preheat Your Equipment:
   Set your oven to 200°C (392°F) and line a baking tray with parchment paper.
2. Combine Ingredients:
   In a pan over low heat, add olive oil and butter. Toss in the sliced onions with a pinch of salt and cook gently for 25–30 minutes until golden and caramelised. Stir occasionally. Once ready, let them cool, then mix in grated halloumi and thyme.
3. Prepare Your Cooking Vessel:
   Roll out your puff pastry and cut each sheet into 4 squares (for a total of 8). Lay them on the prepared baking tray.
4. Assemble the Dish:
   Spoon the filling into one corner of each pastry square. Fold over to form a triangle and press the edges down with a fork. Brush the tops with beaten egg.
5. Cook to Perfection:
   Bake for 18–22 minutes, or until puffed up and deeply golden.
6. Finishing Touches:
   Let them cool slightly on a wire rack. This helps maintain that flaky crunch.
7. Serve and Enjoy:
   Serve warm with a side salad or enjoy cold from the fridge. Perfect with a dollop of chutney or yogurt dip.
