Spaghetti squash is a mildly flavored late summer to early fall variety with flesh that, as the name suggests, can be raked apart into long, spaghetti-like strands after cooking. In a recipe from “Root to Leaf,” Atlanta chef Steven Satterfield tosses roasted spaghetti squash with a light, creamy herb sauce. Not only did we riff on his combination of ingredients, we learned that halving the squash crosswise instead of lengthwise will yield the longest, most spaghetti-like strands because the fibers grow in a spiral around the seedy core of the squash. We think pumpkin seeds and sage leaves toasted in butter are perfect flavor and textural accents for this autumnal dish.
