Delicata squash -- typically a sweeter winter squash -- is rendered more explosive in flavor thanks to the garlic and hot pepper jelly.
Preheat oven to 375 degrees. Stir jelly, oil, and garlic in a small bowl. Place squashes in a large bowl; add jelly mixture and salt. Season with pepper, and toss.
Divide squashes between 2 rimmed baking sheets. Roast until squashes are tender and bottoms are golden brown, 30 to 35 minutes. Serve immediately.
