How to make Keto Apple Pie: step-by-step guide
Cooking methods
Preparation steps
- Gather all necessary ingredients and cooking instruments.
- Peel and dice the zucchini.
- Melt the butter for the crust and the filling.
- Measure out all ingredients using measuring cups and spoons.
- Prepare the pie crust by mixing the ingredients and chilling the dough.
- Cook the zucchini filling and let it cool.
Cooking instructions
- Preheat oven to 350° F.
- Mix all of the crust ingredients in a medium bowl until a thick ball of dough forms. Knead two or three times until smooth. Cut the dough in half and refrigerate for at least 1 hour.
- While the dough is chilling, make the filling. Melt the butter over medium heat in a large 10.5” cast iron skillet. Once melted, add the remaining ingredients and bring to a low simmer for 20 minutes until the mixture is slightly thickened. Whisk in the xanthan gum and cook for another minute until thick. Remove to a bowl and let cool.
- Press half of the dough into the skillet and bake for 12-15 minutes. Remove from oven and let cool for 5-10 minutes before adding the filling to the crust. Sprinkle the top with brown erythritol.
- Roll out the remaining dough between two sheets of parchment paper to roughly the size of the top of the pie. You can either gently transfer the dough to the top of the pie, pinch the border together to seal and cut a star in the middle, or cut the dough into strips to create a lattice effect. Choose any design you prefer.
- Transfer the pie to the oven and bake for 25 minutes. Cover the edges with foil to prevent burning, and continue to cook for another 10-15 minutes. Remove the pie from the oven and let cool before slicing.
Chef's pro tip
Ensuring your dough stays firm is paramount to a successful bake, so don't bypass the chilling step—it's key to achieving that perfect consistency. By combining almond flour and coconut flour, we're able to create an irresistibly flaky crust that adds an extra layer of delight to every bite.
To keep things smooth and stick-free when rolling out your dough, sandwich it between two sheets of parchment paper before going in with the rolling pin. And remember, patience is a virtue—let your creation cool completely before breaking out the sharp knife for slicing. These simple tips promise to take your baking game to the next level!

You can also sub chayote squash for apples in any recipe. Steam them a bit before using in a baking recipe. They are excellent.
Dale says
Just thinking - definitely not criticizing - the crust looks thicker than my preference - the filling thin comparatively. When I make this, I may try to do a 2/3 crust recipe and possibly increase the filling by 25% - always hit or miss when it comes to things like eggs and butter adjustments though.
I am not sure if the crust will hang together as yours does, and by increasing the filling whether it may have a tendency to become more of a "zucchini" pie. It might be easier for me just to use less of the dough. Great concept though - I do miss my apple pie!

What is the sugar alcohol value? Have you counted the sugar alcohol in the carb count? Or do we still get to subtract the sugar alcohol value from the carb value?
Alex Lester says
We don't calculate the sugar alcohols into our recipes as they have zero effect on the nutritional information we provide.
Lamanda Meckle says
May I use a Stevia based sweetener instead, and do you think this pie filling will freeze well. I don't want it to turn to mush, or get watery when I thaw it......
Cast Iron Keto says
You should be able to swap a stevia-based sweetener, as long as it's 1:1 for sugar. As for freezing, I think it would get too watery - you can, however, make the crust ahead of time if needed. Hope this helps!
