Chayote squash is pan fried and then baked in a low carb creamy sauce to make a delicious cheesy side dish. This keto chayote gratin is perfect served with a roast beef or ham dish.

The chayote makes a great potato replacement for a creamy gratin. I sliced the chayote into long strips, but you could cut them into thin scallops for a more traditional gratin looking dish.

Chayote gratin is a very popular side dish in the West Indies and uses a bechamel sauce. Here, I used a low carb cheese sauce made with cream and cheese and cooked it all in one pan without making the sauce separately. You could add bacon to this dish before baking for an extra layer of flavor.

What is a Gratin?

Originally created in France, a gratin is traditional thinly sliced potatoes baked in a rich cheesy sauce.   The vegetables are baked in a shallow dish and cooked until the top is golden. I’ve used chayote to keep the gratin low in carbs.

What Cheese To Use?

If you are a cheese lover, you can used any cheese that melts well. I used a strong English Cheddar cheese, but Gruyere is the cheese of choice for a gratin but Fontina or a strong Gouda work well. Add Parmesan for an extra strong cheese flavor.


A visual guide on how to make a chayote gratin


  • Ensure the chayote are cooked well as they can take a while to bake. It’s often best to precook them before making a gratin.
  • Add chopped spring onions, diced ham or bacon for variety.
  • If you want a crispy topping, sprinkle pork rinds or low carb breadcrumbs on top.
  • If you can’t find chayote, zucchini makes a great replacement.
  • Play around with herbs and spices with thyme, basil and nutmeg as a few that would enhance the flavour.
