How to Prepare Chayote Squash

Wash the chayote, cut it in half, and remove the soft seed in the center. The skin is edible when tender, but peeling it can give cooked chayote a smoother texture. Cut the flesh into cubes, slices, or sticks depending on how you plan to use it.

Roasted Chayote

Cut the chayote into evenly sized cubes and toss with a small amount of olive oil and your preferred seasonings. Spread the pieces in a single layer on a baking sheet. Roast at 425°F for about 25–35 minutes, stirring once or twice, until tender and lightly browned.

Chayote Fries

Cut the chayote into evenly sized sticks and pat them dry before seasoning. Toss with a small amount of oil, then spread them in a single layer on a baking sheet. Bake at 425°F for about 30–40 minutes, turning halfway through, until tender and browned around the edges.

Using Chayote as a Potato Substitute

Chayote can replace potatoes in roasted side dishes, soups, stews, casseroles, and many skillet meals. Its mild flavor allows it to take on the seasonings and sauces used in the dish.

Chayote contains much less starch than potatoes and has a lighter, slightly crisp texture. It will not become as fluffy as a baked or mashed potato, but it holds its shape well during cooking and works especially well in recipes that call for diced or sliced potatoes.

Quick Tip: Chayote contains a sticky sap that can coat your hands while peeling or cutting it. Rinsing the squash under cool water while handling it or wearing kitchen gloves can make preparation easier.
