Bake, uncovered, five more minutes. Microwave variation: Prepare vegetable mixture, then pour into a microwave-safe casserole. Microwave, covered with vented plastic wrap, on high eight to 10 minutes.

Post a comment. You can fry your onions or shallots in vegetable oil (or take a shortcut with either the microwave or air fryer), but no one would fault you for buying a tub of pre-fried French’s.
