Peel squash. Cut in half lengthwise; discard seeds and membrane. Cut each squash half crosswise into 1/2-inch-thick slices; place in a 13- x 9-inch baking dish, overlapping if necessary. Combine juice, sugar, cinnamon, salt, and nutmeg; pour over squash.
Cover squash mixture with foil; bake at 400° for 25 minutes or until tender. Top with almonds.
