Ingredients
For the Keto Pie Crust
-
2 ½ cups almond flour
-
¼ cup Keystone Pantry Allulose
-
½ teaspoon salt
-
½ teaspoon cinnamon (optional)
-
½ cup unsalted butter, cold and cubed
-
1 large egg
-
1 teaspoon vanilla extract
-
1-2 tablespoons ice water (if needed)
For the Keto “Apple” Filling (Apple Substitute: Chayote or Zucchini!)
-
4 cups chayote squash (peeled, cored, and sliced) or 4 cups zucchini, peeled and sliced
-
½ cup Keystone Pantry Allulose
-
2 tablespoons unsalted butter
-
1 teaspoon cinnamon
-
¼ teaspoon nutmeg
-
1 teaspoon vanilla extract
-
1 tablespoon lemon juice
-
½ teaspoon xanthan gum (for thickening)
For the Egg Wash
-
1 egg, beaten
-
1 tablespoon water
Instructions
1. Make the Keto Pie Dough
-
In a food processor or mixing bowl, combine almond flour, allulose, salt, and cinnamon.
-
Add cold cubed butter and pulse (or cut in with a pastry cutter) until the mixture resembles coarse crumbs.
-
Mix in the egg and vanilla extract. If the dough is too dry, add 1 tablespoon of ice water at a time until it comes together.
-
Divide the dough in half, shape into discs, wrap in plastic, and refrigerate for at least 30 minutes.
2. Prepare the Keto “Apple” Filling
-
In a large skillet over medium heat, melt the butter.
-
Add sliced chayote squash or zucchini, allulose, cinnamon, nutmeg, and lemon juice. Stir well.
-
Cook for 10-12 minutes until the slices are tender but not mushy.
-
Sprinkle in xanthan gum and stir to thicken. Remove from heat and mix in vanilla extract. Let cool slightly.
3. Assemble the Pie
-
Preheat oven to 375°F (190°C).
-
Roll out one dough disc between parchment paper and carefully place it in a 9-inch pie pan. Trim excess dough.
-
Fill with the chayote or zucchini filling.
-
Roll out the second dough disc and cut into strips. Arrange in a lattice pattern over the filling.
-
Brush with egg wash for a golden finish.
4. Bake the Pie
-
Bake for 50-60 minutes, until the crust is golden brown and the filling is bubbly.
-
If the crust browns too quickly, tent with foil.
-
Let cool for at least 2 hours before slicing.
Why This is Keto-Friendly
✔ Apple Swap: Chayote squash or zucchini mimics apples in texture and absorbs apple-like flavors!
✔ Allulose Sweetener: Keeps it sugar-free and low in net carbs.
✔ Almond Flour Crust: No high-carb wheat flour.
Pair with sugar-free whipped cream or keto vanilla ice cream!
Chayote squash is a fantastic keto-friendly substitute for apples because:
1. Low in Carbs
-
Apples are high in natural sugars, with 25-30g net carbs per apple.
-
Chayote squash has only ~2g net carbs per cup, making it perfect for keto.
2. Mild Flavor & Apple-Like Texture
-
Chayote has a neutral, slightly sweet taste that absorbs flavors well.
-
When cooked, it softens just like apples without becoming mushy.
3. Holds Shape Well
-
Unlike some other low-carb substitutes (like zucchini, which can get watery), chayote maintains a firm yet tender texture when baked.
4. Works Well with Spices & Sweeteners
-
When cooked with cinnamon, nutmeg, allulose, and lemon juice, chayote takes on a classic apple pie flavor—you’d barely notice the difference!
Alternative Apple Substitutes for Keto
✔ Zucchini – Works well but can be softer and a bit more watery.
✔ Jicama – Has a crisp texture but takes longer to cook.
✔ Daikon Radish – When sweetened and spiced, it mimics apple flavor surprisingly well!
Chayote is the best overall choice for a realistic apple substitute in keto recipes!
