Preheat the Oven. While the crust is setting in the freezer, preheat your oven to 320°F (160°C) for fan-assisted ovens, or 355°F (180°C) for conventional ovens

Mix the Filling. In a stand mixer, gently beat the apple butter and eggs until well combined. Next, add in the heavy whipping cream or coconut cream, sweetener, and spices. Mix everything on low speed until it’s thoroughly mixed.

Tips for the Best Zucchini Apple Pie

  • Chill the Crust: Pre-freezing the crust helps it keep its shape and ensures a crispy base.
  • Low and Slow: Bake the pie at a lower temperature to allow the filling to set without burning the crust.
  • Even Mixing: Use a stand mixer for a uniformly smooth filling, ensuring all spices are well incorporated.
  • Cool Completely: Let the pie cool to allow the filling to firm up for clean slices.
  • Spice to Perfection: Don’t be shy with the cinnamon and nutmeg; they’re key to that classic fall flavor.

Storage Instructions

You can store this pie in the fridge for up to 5 days, or freeze for up to 6 months. To serve, let it defrost in the fridge overnight and optionally reheat in the oven before serving.
