For cooking the squash whole, wash and dry it thoroughly. Then, air fry for 20-30 minutes or bake in the oven for 35-45 minutes, until a fork easily pierces the flesh. After cooking, cut the squash in half and scoop out the seeds. Brush the flesh with maple syrup and sprinkle with thyme. You can stuff the squash, use it in other recipes, or make a homemade puree.
