Mushroom & Cheddar Stuffed Onions
Make Ahead Tip: Prepare through Step 4; refrigerate for up to 1 day. Let stand at room temperature while oven preheats.
Tip: To make your own fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. To make fine breadcrumbs, process until very fine. To make dry breadcrumbs, spread coarse or fine breadcrumbs on a baking sheet and bake at 250°F until dry, about 10 to 15 minutes. One slice of bread makes about 1/2 cup fresh breadcrumbs or about 1/3 cup dry breadcrumbs. For store-bought coarse dry breadcrumbs we like Ian's brand, labeled “Panko breadcrumbs.” Find them at well-stocked supermarkets.
