Preheat the oven: Set your oven to 375°F (190°C).
Place a rack in the lower-middle position to help the crust bake evenly.
Make the crust: In a bowl, mix almond flour (or white whole-wheat flour), coconut sugar, and salt. Stir in melted coconut oil or butter. For almond flour, the mixture should press together like damp sand; for whole-wheat flour, add 1–2 tablespoons cold water until it holds when pinched.
Press and par-bake: Press the crust firmly and evenly into a 9-inch pie plate, going up the sides.
Prick the bottom with a fork. Bake for 10 minutes to set. If using whole-wheat flour, line with parchment and pie weights for cleaner edges, then remove weights after 10 minutes.
Lower the oven: Reduce the oven temperature to 350°F (175°C) after the crust par-bake.
Mix the filling: In a large bowl, whisk pumpkin, eggs, Greek yogurt, maple syrup, brown sugar (if using), vanilla, spices, and salt until smooth.
Avoid over-whisking to reduce air bubbles.
Fill the crust: Pour the filling into the warm crust. Tap the pie plate gently on the counter to release any air bubbles.
Bake until set: Bake at 350°F for 35–45 minutes. The edges should be set, and the center should have a slight jiggle, like gelatin. Do not overbake—it will firm up as it cools.
Cool completely: Let the pie cool on a rack for at least 2 hours.
This helps the custard finish setting and makes for neat slices.
Chill (optional but recommended): Refrigerate for 2–4 hours for the cleanest cut and best texture.
Serve: Slice and top with a dollop of whipped coconut cream or Greek yogurt. Add toasted pecans for crunch if you like.
