Ingredient Notes

Here's a quick overview of the ingredients (just a handful of them!) we use for this easy recipe - plus potential substitutions.

• Puff pastry sheet - Jus-Rol works brilliantly, but any ready-to-use rolled pastry will save time. Ideally, use it at room temperature. Too cold and the pastry can crack, and too warm and it will get sticky.
  
•  Green pesto - Any store-bought pesto works well; I just made sure mine was vegetarian-friendly. Fresh homemade basil pesto = even more flavour, if you have the time. Red pesto also works and makes red & green trees if you mix colours.
  
•  Shredded cheddar + mozzarella - Cheddar gives sharp flavour, while mozzarella adds melt + stretch. Parmesan is lovely sprinkled on top, pre-bake for those extra crisp edges.
  
• Egg wash - Gives a glossy golden finish. Milk also works in a pinch.
  
• Cheddar star toppers - Cute, festive additions to your pastry trees! These are optional but recommended. You can also use mini mozzarella pearls, olives or edible gold stars.
  
• Skewers - Make these portable and help the tree hold its shape while baking.

1. Preheat your oven to 200C | 395F.

4. Fold pastry in half (width to width) and press lightly to seal.
   
5. Slice into 5cm strips.
   
6. Create tree shapes by folding each strip back and forth, stacking layers wider at the base and narrower toward the top (like ribboning).
   
7. Insert a bamboo skewer from the top down through the centre - leave space at the top for the cheese star.
   
8. Arrange trees on a lined baking tray.
   
9. Brush with egg wash.
   
10. Bake 20-25 mins, or until puffed, golden, and crisp.

Chef's Tips / Tricks

• Add chilli flakes or sun-dried tomatoes inside to bulk up the recipe and add more flavor.
  
• For extra crunch: sprinkle parmesan over the tops before baking.
  
• Swap pesto for garlic butter, olive tapenade, or cranberry + brie for slightly more festive variations.

Storage

• Best fresh - puff pastry is peak delicious the minute it exits the oven.
• Can be stored in the fridge for 1-2 days and re-heated at 180°C for 7-10 minutes.
• To make ahead: assemble trees, refrigerate raw overnight, bake when needed.
