Cheesy Mustard Puff Pastry Pie


Introduction
This puff pastry pie is the definition of comfort food—flaky, buttery pastry filled with the sharp tang of mustard and the gooey richness of melted mozzarella cheese. Originating from European traditions where puff pastry was considered a “luxury dough,” this dish is a modern twist that turns simple ingredients into a show-stopping centerpiece.
Ingredients
- 2 x 400 g sheets puff pastry (store-bought or homemade)
- 3–4 teaspoons Dijon or wholegrain mustard (adjust to taste)
- 150 g hard mozzarella cheese (grated or sliced)
- 1 egg (for egg wash)
- Optional: fresh herbs (thyme, oregano, or parsley), cracked black pepper
Instructions
- Preheat Oven: Heat to 200°C (400°F). Line a baking tray with parchment paper.
- Prepare Pastry Base: Lay one sheet of puff pastry on the tray. Gently prick it with a fork to prevent puffing too much.
- Spread Mustard: Evenly spread the mustard over the pastry, leaving a 1–2 cm border.
- Add Cheese: Sprinkle grated mozzarella generously over the mustard. Add herbs or black pepper if desired.
- Seal the Pie: Place the second puff pastry sheet over the top. Press edges together with a fork to seal.
- Egg Wash: Beat the egg and brush it over the pastry for a golden finish.
- Bake: Place in oven for 20–25 minutes, or until puffed and golden brown.
- Cool Slightly & Serve: Let rest for 5 minutes before slicing. Serve warm with salad or soup.
Methods
- Variation 1: Add caramelized onions for sweetness.
- Variation 2: Mix mozzarella with cheddar or Gruyère for extra flavor.
- Variation 3: Turn into small pastries by cutting into squares or rolls before baking.
History
Puff pastry dates back to 16th-century France and Spain, inspired by laminated dough techniques from the Middle East. Mustard has been used since Roman times, while mozzarella originated in southern Italy. Combining these three creates a dish that bridges French elegance with Italian heartiness.
