Step-by-Step Instructions
Step 1: Preheat the oven and prep your dish
Set your oven to 200°C (400°F). Place a rack in the middle of the oven.
Have a 20 cm (8-inch) pie dish or similar baking dish ready (a small casserole dish works too). If you’re using puff pastry from the freezer, make sure it’s fully thawed in the fridge so it’s pliable but still cool.
Step 2: Build the flavor base (onion, aromatics, curry paste)
Heat 1 tbsp neutral oil in a large skillet or sauté pan over medium heat. Add the diced onion and cook for 5 minutes, stirring occasionally, until softened and translucent.
Add the minced garlic and grated ginger. Cook for 1 minute, stirring constantly so it doesn’t scorch.
Add the 3 tbsp green curry paste and stir it into the onions for 1 minute. This brief “toasting” helps the curry paste bloom and become more fragrant.
Step 3: Simmer the sauce and cook the sweet potato
Pour in the 400 ml coconut milk and 200 ml vegetable stock. Stir well, scraping the bottom of the pan so the curry paste fully dissolves into the liquid.
Stir in 1 tbsp soy sauce and 2 tsp brown sugar. Bring the mixture to a gentle simmer.
Add the cubed sweet potato. Reduce heat to medium-low, cover, and simmer for 12–15 minutes, stirring once or twice, until the sweet potato is nearly tender (it should yield to a fork but not fall apart). This prevents mushy filling after baking.
Step 4: Add the quick-cooking vegetables and thicken the filling
Add the bell pepper pieces and frozen peas. Simmer uncovered for 3–4 minutes, just until the pepper starts to soften and the peas are hot.
In a small bowl, mix 1 tbsp cornstarch with 2 tbsp cold water until smooth. Pour the slurry into the simmering sauce and stir for 1–2 minutes until the filling noticeably thickens to a creamy, spoon-coating consistency.
Turn off the heat. Stir in 1 tbsp lime juice, the torn basil, and (if using) cilantro. Taste and adjust salt as needed (the saltiness will depend on your curry paste and soy sauce).
Step 5: Transfer to the pie dish and cool briefly
Spoon the filling into your 20 cm (8-inch) pie dish and spread it into an even layer.
Let it cool for 10 minutes. This small pause helps keep the puff pastry crisp (steam from piping-hot filling can make pastry soggy).
Step 6: Top with puff pastry and seal
Lay the puff pastry sheet over the dish. Trim it so you have about a 1–2 cm overhang.
Tuck the edges slightly down the inside of the dish or crimp against the rim, depending on your dish shape. The goal is a good seal so the pastry “lid” puffs nicely and stays in place.
Cut 3–4 small slits in the top for steam to escape (this reduces overflow and helps keep the pastry flaky).
Step 7: Brush, bake, and rest
In a small bowl, whisk 1 egg with 1 tbsp water. Brush a thin, even layer over the pastry. If you’d like, sprinkle with 1 tsp sesame seeds.
Bake at 200°C (400°F) for 20–25 minutes, until the pastry is deeply golden, crisp, and puffed. If the top is browning too quickly, loosely tent with foil for the last 5 minutes.
Let the pie rest for 10 minutes before serving. This gives the filling time to set slightly, making it easier to slice and spoon without running.
Pro Tips
- Control the heat level: Green curry paste varies a lot. Start with 2 tbsp if you’re cautious, then add the third tablespoon after tasting the sauce.
- Keep the pastry cold: Puff pastry puffs best when it goes into the oven chilled. If it starts feeling soft or sticky, refrigerate it for 10 minutes before topping the pie.
- Thicken enough before baking: The filling should be creamy and thick (not soupy) before it goes under pastry, or it can seep and soften the crust.
- Cut evenly sized sweet potato cubes: Aim for 1.5 cm so they cook through quickly and evenly.
- Resting matters: That 10-minute rest after baking improves both texture and serving ease.
Variations
- Add protein: Stir in 1 can (400 g) chickpeas (drained and rinsed) with the peppers and peas for extra body.
- Extra greens: Add 80 g baby spinach at the very end (after thickening). Stir just until wilted.
- More aromatic finish: Add 1/2 tsp toasted sesame oil and a little extra lime juice right before serving for a punchy finish.
Storage & Make-Ahead
Cool leftovers completely, then refrigerate in an airtight container for up to 3 days. Reheat in a 180°C (350°F) oven for 15–20 minutes to re-crisp the pastry (microwaving warms it quickly but softens the crust).
Make-ahead option: Cook the filling up to 2 days in advance and refrigerate. When ready to bake, warm the filling just until it’s no longer fridge-cold (about 5–7 minutes on the stove), cool for 10 minutes, then top with pastry and bake as directed.
