Chayote squash halves stuffed with cheese and baked until golden and bubbling. This vegetarian dish is healthy, naturally low in calories, and makes a delightful family side or light main.
Preheat oven to 400°F, ensuring racks are centered for even heat distribution.
Halve the chayote squashes lengthwise. Carefully scoop out the flesh, leaving a 1/4-inch shell, and set flesh aside.
Heat 1 tablespoon olive oil in a skillet over medium heat. Sauté onion and chopped chayote flesh for 5–7 minutes until softened and excess moisture evaporates.
Remove from heat, stir in mozzarella, parmesan, salt, pepper, and garlic powder. Mix until combined.
Fill the chayote shells generously with the stuffing mixture. Drizzle remaining olive oil over the tops, and bake for 25–30 minutes until golden and bubbling. For extra browning, broil for 2–3 minutes at the end.
