Chayote Squash Keto Recipes

Zucchini is often used for a low carb alternative to apple and since the chayote is often used as a local substitute for zucchini, I thought I would try it in an apple crumble. The vegetable itself is fairly bland so lots of apple pie spice was used. I was heavy with the cinnamon, added nutmeg and ground cloves into the mix.

This low carb mock apple crumble dessert was met with happy eating noises from the Chief Taster. Apple crumble was the first dessert I made for him when we were dating many, many years ago and it’s been on his favourite dessert list forever. Now we have this low carb mock apple crumble firmly on the dessert list. Try it in an “apple” crumble muffin too!

What is Chayote Squash?

Chayote squash belongs to the gourd family and originates from Mexico and South American. It has a pear shape and is available rough and prickly. In the Caribbean the chayote is also known as Christophine or Cho-Cho.

The flesh has a very mild taste and can be served raw or cooked. Technically, the chayote is a fruit but we treat it like a vegetable in stews and salads. This recipe treats the chayote as a mock apple crumble filling.

A cup of chayote (132g) has a total of 6g carbs, 2.2g fibre with net carbs being 3.8g making it an ideal substitute for apple or even pear.


Chayote Crumble Tips

  • Slice the chayote evenly and thin. About 5mm thin will ensure an even cooking.
  • Do not be shy with the spice. The chayote does not have an apple taste,so you need all the spices of an apple pie.
  • If you have low carb brown sugar, add that to the chayote crumble for an additional flavor.
  • Serve with whipped cream or a side of low carb cinnamon ice cream

    Is the chayote difficult to peel? I have used yellow summer squash and scallop squash for mock apple, but didn’t have to peel them. Difficult to find this time of year if I want organic. Thanks!

      I found it fairly easy to peel. It’s a bit like a pear. Yellow summer squash would make a great replacement though!

    Love your recipes! FYI, adding fresh lemon juice can really punch up the apple flavor, as can a bit of salt.
