Growing up, I never imagined I’d find a way to enjoy apple pie while staying true to my keto lifestyle. But this Keto Apple Pie changed everything – proving that low-carb doesn’t mean sacrificing the warm, comforting flavors we crave. Using clever ingredient swaps, this dessert delivers all the buttery, spiced goodness of traditional apple pie without the carb overload.
Ingredients List
For the Crust:
- 2 cups almond flour
- 1/4 cup coconut flour
- 1/3 cup cold butter, cubed
- 1 large egg
- 2 tablespoons erythritol
- 1/2 teaspoon salt
For the Filling:
- 4 medium chayote squash, peeled and sliced thin (or jicama as substitute)
- 1/2 cup powdered erythritol
- 2 tablespoons lemon juice
- 1 1/2 teaspoons cinnamon
- 1/4 teaspoon nutmeg
- 1/4 teaspoon allspice
- 2 tablespoons butter, diced
- 1 tablespoon xanthan gum
Substitution suggestions: Replace chayote with thinly sliced turnips or radishes for different texture profiles. Sugar-free monk fruit sweetener works beautifully in place of erythritol.
Timing

Time-saving tip: Prepare the crust dough the night before and refrigerate. This makes assembly quicker and helps develop better texture.
How to Make It
1. Prepare the Keto Pie Crust
Preheat your oven to 375°F. In a large bowl, combine almond flour, coconut flour, erythritol, and salt. Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs – you’ll hear a satisfying scraping sound as the butter breaks down. Beat the egg and mix it in until dough forms. The texture should feel slightly sandy but hold together when pressed. This creates the perfect foundation that won’t get soggy under the filling.
2. Create the Apple-Like Filling
Peel and slice your chayote squash into thin, apple-like wedges – aim for 1/4-inch thickness for even cooking. Toss the slices with lemon juice immediately to prevent browning and add that bright, tart flavor reminiscent of Granny Smith apples. In a separate bowl, whisk together powdered erythritol, cinnamon, nutmeg, allspice, and xanthan gum. The xanthan gum is crucial here – it helps thicken the natural juices during baking, preventing a watery pie.
3. Assemble Your Low-Carb Masterpiece
Roll out two-thirds of your dough between parchment paper sheets until it’s roughly 12 inches in diameter. Gently transfer to a 9-inch pie pan, pressing into corners without stretching. Layer your seasoned chayote slices in overlapping circles, creating height in the center. Dot with butter pieces – they’ll melt and create rich pockets of flavor throughout. The filling should mound slightly above the rim.
4. Add the Top Crust and Bake
Roll remaining dough for the top crust, laying it over the filling. Trim excess dough, leaving about an inch overhang. Fold edges under and crimp with a fork or your fingers – listen for the slight squish as layers seal together. Cut four steam vents in the top. Bake for 45 minutes until the crust turns golden brown and you can hear gentle bubbling from within. The aroma of warm spices will fill your kitchen, signaling it’s nearly ready.

Serving Suggestions
Serve warm with a dollop of sugar-free whipped cream or a scoop of vanilla keto ice cream. The contrast between the warm, spiced filling and cool cream creates the perfect bite. Cut into 8 generous slices for a satisfying recipe that serves the whole family.
Common Mistakes to Avoid
Overmixing the crust dough leads to tough, dense pastry – mix just until combined. Skipping the xanthan gum results in runny filling that won’t set properly. Not pre-treating chayote with lemon juice can cause slight discoloration. Opening the oven door too frequently releases heat and prevents proper browning of the crust.
Storing Tips
Store covered in the refrigerator for up to 5 days. The flavors actually improve after a day as spices meld together. For best results, reheat individual slices in a 300°F oven for 8-10 minutes to restore the crust’s crispness.

Conclusion
This Keto Apple Pie proves that following a low-carb lifestyle doesn’t mean missing out on beloved comfort foods. With its flaky almond flour crust and perfectly spiced filling, it’s a dessert that will fool even the most discerning palate.
FAQs
Can I make this pie ahead of time?
Absolutely! Bake completely, cool, and refrigerate up to 2 days before serving. The filling actually sets better overnight, making slicing easier.
What if I can’t find chayote squash?
Jicama works wonderfully as a substitute, offering similar texture and neutral flavor. Turnips are another excellent option, though they’re slightly more peppery.
Why is my filling too watery?
This usually happens when xanthan gum is omitted or the pie isn’t baked long enough. Ensure you bake until bubbling sounds are audible.
Can I freeze leftover slices?
Yes! Wrap individual slices in plastic wrap and freeze up to 3 months. Thaw overnight in the refrigerator before reheating.
How do I know when the crust is properly done?
Look for a golden-brown color and listen for gentle bubbling from the filling. The crust should feel firm when gently tapped. Check out more amazing recipe ideas on our Pinterest for additional inspiration!
