If you’ve been looking for a keto apple crisp recipe, I’ve got one here for you that doesn’t use apples at all! By using chayote squash and the right spices, you’ll be thrilled with this keto mock apple crisp recipe.

Are Apples Low Carb Friendly?

When considering a low carb lifestyle, it really depends on how many carbs you aim to consume on a daily basis. Generally speaking, apples are quite high in carbohydrates. One medium apple has around 20g net carbs. For some, that is their entire carb count for the whole day!

Unfortunately, apples are not very friendly for a keto or low carb lifestyle.

Is Chayote Squash Keto-Friendly?

If you’ve never heard of chayote squash, don’t worry! I wasn’t super familiar with them aside from seeing them in the grocery store. Turns out, chayote squash is fantastic for a low carb lifestyle! With only 4g Net carbs per cup, this squash variety is very keto-friendly.

How does Chayote Squash taste?

Chayote squash has a mild flavor with slightly sweet undertones. It can be eaten raw or cooked, skin on or skin off. Apparently, the pit is edible, but I don’t really recommend that.

Ingredients for this Keto Apple Crisp Recipe

The ingredients for this keto “apple” crisp are pretty easy to find. This recipe doesn’t use apple extract, but if you’ve got some you’re welcome to add 1 tsp!

Many Latino markets will stock chayote squash!

If your grocery store doesn’t carry chayote squash, you can ask someone in the produce department if they have access to it and request they special order it for you. When I used to work in a produce department, we’d meet our customer’s needs this way.

Note on Monkfruit Sweetener:

Monkfruit sweetener is a low-carb and keto-friendly sweetener that is made from a mixture of monkfruit and erythritol. It has zero net carbs and measures 1:1 like sugar. It also has a zero glycemic impact which means it is a great sweetener for diabetics. Lakanto is the brand that I prefer and they make golden, white, and powdered versions. Many enjoy the golden variety as a substitute for brown sugar. The powdered variety is 2x sweeter than sugar, so you don’t need to use as much.

Tips for making this Keto Apple Crisp Recipe

To prepare your chayote squash, cut the squash in half lengthwise, then scoop the pit out.

Optional – Peel the chayote squash. While the peel can be eaten, it is a little tough once cooked.

While combining the crumble topping, you’ll use cold butter and cut it into small pieces. The easiest way to combine the almond flour, flax, sweetener, and spices with the butter is by using a pastry blender. If you don’t have a pastry blender, you can use two forks to get the butter into very small pieces (like a grain of rice).

Before you put the crumble on top, you’ll stirfry the chayote with butter and spices to soften it. This will take a few minutes. After the chayote is tender, you can top it with the crumble mixture then bake it.

If you have a favorite keto-friendly vanilla ice cream, that would go well with this mock apple crisp, or you could serve it with whipped cream! Both of these options are wonderful. Below, you’ll also find a caramel sauce recipe that would be a great addition as well!

-You can eat the skins of the chayote squash, but depending on the age of the squash, it might be tough. I suggest peeling the squash.
-Adding apple extract is entirely optional. If you don’t have it, you’ll still enjoy this mock apple crisp! 
-You could use a grater to get butter it into a small piece consistency if you’d like.
-This recipe is best eaten fresh. It will get soggy if stored in the fridge (still delicious, not as beautiful).
