In a small bowl, mix melted butter, brown sugar, orange zest, and rosemary until smooth.
Preheat oven to 400F and lightly grease a large sheet pan. Cut honeynut squashes in half and use a spoon to scoop out seeds. Brush cut sides of squash liberally with brown sugar glaze, season with salt and pepper, and place squash cut side-up on prepared sheet pan.
Roast honeynut squash at 400F 25-35 minutes until squash is tender when pierced with a fork. Spoon collected glaze in cavity of squash over the rest of squash, top with pecans if using, and serve warm. Enjoy!
