I bake my squash (butternut, etc.) cut side down on parchment paper, 350 degrees, for 50-60 minutes. Seems to work out fine. When I was first learning to cook I followed recipes which called for oiling the cut side and baking cut side up.
I was just looking at this NYTimes recipe Butternut Squash Soup and it reminded me of the early recipes I learned from:
Rub the flesh of the squash with 1 tablespoon oil and season with salt. Place the squash cut sides up on a small baking sheet, and cover tightly with foil. Bake until the flesh is tender and a knife can be inserted easily, about 50 minutes.
My question: is there a point to that extra effort? What benefit is there with the oiling/covering with foil vs. just baking cut side down? With the latter, the cut surface is protected and does not dry out. The salt can be added later.
Am I missing some cooking nuance here or is this simply a matter of style (and/or parchment paper)?
