Serves: 12+

🥧 Ingredients

For the GF Pie Crust:

3 cups gluten-free all-purpose flour (like Bob’s Red Mill 1:1)
1 tbsp coconut sugar (or granulated sugar)

1 tsp salt
1 cup cold unsalted butter, cubed (or dairy-free butter)
1 large egg (or 1 flax egg for vegan)

4-6 tbsp ice water

For the Apple Filling:

6-7 cups peeled & thinly sliced apples (Granny Smith + Honeycrisp mix)
½ cup coconut sugar (or brown sugar)

2 tbsp lemon juice
2 tsp cinnamon
½ tsp nutmeg

¼ tsp allspice
¼ tsp salt
3 tbsp tapioca starch (or cornstarch)

For Topping (Optional):

1 egg + 1 tbsp water (egg wash)
Turbinado sugar for sprinkling

📝 Instructions

1️⃣ Make the Crust

In a food processor, pulse flour, sugar, and salt.

Add cold butter and pulse until crumbly.
Mix in egg and ice water, 1 tbsp at a time, until dough forms.
Divide dough in half, shape into discs, wrap in plastic, and chill 1 hour.

2️⃣ Prep the Filling

Toss apples with lemon juice, sugar, spices, salt, and tapioca starch.

3️⃣ Assemble & Bake

Preheat oven to 375°F (190°C).
Roll out 1 dough disc on parchment paper to fit a 10×15-inch jelly roll pan.

Spread apple filling evenly over crust.
Roll out second dough disc, place on top, and crimp edges.
Cut slits in the top, brush with egg wash, and sprinkle with sugar.

Bake 35-40 mins until golden and bubbly. Cool before slicing.

💡 Tips for Success

✔ Keep dough cold—warm dough = tough crust!
✔ No food processor? Use a pastry cutter or fork.
✔ Extra flavor? Add 1 tsp vanilla to the filling.
✔ Make ahead: Freeze unbaked pie up to 3 months!
