Return cut squash to the same baking sheet. Heat the 1/4 cup maple syrup and 2 Tbsp. butter in the microwave or a small saucepan until the butter is melted. Stir well to combine. Brush with maple/butter mixture and sprinkle with salt and pepper. Sprinkle dried thyme leaves over squash, trying to get in the slits a bit, if possible. Pour 1/4 cup water in to bottom of pan, then return to 425F oven for 15 minutes. Remove from oven, baste with more maple/butter mixture. add another 1/4 of water to the pan and return to the oven for a further 15 minutes.
