Ingredients

  • 1 9-inch keto pie crust, pre-baked if required
  • 4 large chayote squash (about 2 pounds), peeled and chopped
  • 2 tablespoons unsalted butter, melted
  • 1 tablespoon lemon juice
  • 1 cup granulated keto sweetener (erythritol, allulose, or monk fruit blend)
  • 1½ tablespoons coconut flour
  • 1 teaspoon ground cinnamon
  • 1 teaspoon apple extract (optional)
  • ½ cup almonds, finely chopped
  • 1 cup blanched almond flour
  • ½ cup coconut oil, melted and cooled
  • ½ cup unsweetened shredded coconut
  • ¼ cup keto brown sugar or granulated erythritol

Instructions

  1. Preheat oven to 180°C (350°F). Prepare the keto pie crust as directed and set aside.
  2. In a large bowl, mix chopped chayote, melted butter, lemon juice, sweetener, coconut flour, cinnamon, and apple extract (if using) until well coated.
  3. In a separate bowl, combine chopped almonds, almond flour, coconut oil, shredded coconut, and keto brown sugar. Stir until a crumbly mixture forms.
  4. Spread the chayote filling into the prepared pie crust.
  5. Bake for 20 minutes.
  6. Remove from oven, sprinkle crumble topping evenly over the filling, and return to oven.
  7. Bake an additional 15–20 minutes, until the topping is golden brown.
  8. Let rest for 5 minutes before slicing and serving warm or chilled.

Notes

  • Chayote squash mimics apple texture when baked with spices and sweetener.
  • Apple extract is optional but enhances the apple-like flavor.
  • Coconut flour absorbs moisture and keeps the filling from becoming watery.
  • Pie can be made ahead and stored chilled or frozen.
