Love yellow squash. Smothering is a Cajun cooking term that refers to browning anything from meat to vegetables in oil, then braising it in a small amount of liquid, tightly covered, until tender. The recipe comes from Gourmet magazine.
Heat 1 tablespoon olive oil in a 12-inch heavy skillet over moderately high heat until hot, But not smoking, then add half of the squash and saute, stirring occasionally, until browned, about 5 minutes.
Transfer browned squash to a bowl, then heat remaining olive oil and saute remaining squash in the same manner.
Return squash from bowl to skillet, add garlic and saute, stirring occasionally, 1 minute.
Add water, salt, and pepper and simmer briskly, covered, until squash is tender and most of the liquid has evaporated, 6 to 7 minutes.
