Instructions
Blind-bake the Pie Crust
Make the pie dough ahead of time so it has time to rest for at least 2 hours, but ideally overnight, then shape it into the pie dish at least 30 minutes before baking. Full instructions in my Flaky Pie Crust post. Alternatively, you can use a store-bought pie crust.
Cover the inside of the pie with parchment paper and fill with baking beans and/or rice. Make sure you fill it all the way up the sides of the pie crust to stop the edges from shrinking.
Keep the pie crust in the fridge, or if there is space, pop it in the freezer for 10 minutes while you preheat the oven to 425°F / 220°C (200°C fan assisted).
Put the pie crust into the oven on the middle rack and bake for 15-18 minutes or until the edges are starting to turn golden brown.
Take the pie out of the oven and turn the temperature down to 375°F / 190°C (170°C fan assisted). Carefully lift out the parchment paper and baking beans.
Brush a layer of egg wash on the bottom and sides of the pie, it should be a thin layer, but thick enough to seal any docking holes. Return the pie crust to the oven for a further 5-7 minutes, or until the inside looks dry and light golden brown.
Remove from the oven and let the pie crust cool while you make the custard filling.
Make the Coconut Custard Filling
Set the oven temperature to 325°F / 160°C (140° fan-assisted).
In a large bowl, whisk together the eggs, egg yolk, sugar, and salt. Whisk gently just until combined - don't try to incorporate any air into the mixture.
To a saucepan, add the milk, coconut milk, and vanilla, mix together and warm over medium-low heat until it is scalding hot. This means there is steam coming from it and you can see a few tiny bubbles starting to form on the surface. Don't let it boil.
Slowly drizzle a tiny amount of the hot milk into the egg mixture and whisk it in gently. Keep adding it, a little at a time, until it is all incorporated.It is vital to do this gradually to slowly bring up the temperature of the eggs so that they don't scramble.
Pour the custard mixture through a fine mesh sieve into a large bowl to remove any lumps of coagulated egg. Tip: If you have a bowl with a spout on it, it makes pouring into the pie crust a lot easier!
Divide the coconut into 1 cup and ¼ cup (80g and 20g). Set the smaller amount aside for topping the pie later.
Add the larger portion of coconut into the custard and mix to disperse it evenly. Let it sit for 5-10 minutes so it can absorb some of the liquid.
Stir the coconut through the custard one more time, then pour the filling into your baked pie crust.
Carefully transfer the custard pie to the middle rack of your oven and bake for 40- 50 minutes. If the pastry starts to brown too much but the pie isn't ready, you can add a pie shield to stop it from browning further.
Bake time will vary massively depending on a variety of factors, so it's best to know the signs of when it is done. Tap or move the pie dish very slightly. When custard pie is properly baked, the outer 1-2 inches of pie will be set and firm, but the middle will still jiggle. See the post above for more details.
Remove the pie from the oven and let it cool to room temperature before transferring it to the refrigerator to chill for at least 4 hours - preferably overnight.
To Decorate
Spread the reserved shredded coconut on a baking sheet and toast it in the oven at 350°F / 180°C for a few minutes, just until brown and fragrant.
Once cooled, sprinkle the toasted coconut generously over the top of the pie.
Pie Crust - I recommend making homemade pie dough from scratch, but if you don't want to make it from scratch, you can buy a store-bought pie crust. It should be 9 inches and deep dish. Coconut Milk - Make sure it is full-fat coconut milk, not coconut cream. Shake the can well to make sure the fats and liquids are well incorporated. If you open the can and they are still separated, just mix them well with a spoon until smooth. Coconut - Use shredded coconut for subtle texture, or coconut flakes for big chunks. I used unsweetened shredded coconut but if you'd like stronger flavor you can use sweetened. Whole Milk - It's important to use full-fat milk so there is enough fat and protein to make the custard set properly.
