Slow Roasted Onions and Garlic

A recipe from Georgia Department of Education School Nutrition

Slow-roasting onions and garlic transforms them into tender, sweet perfection, mellowing their sharp flavor. This method is ideal for busy kitchens, as the onions and garlic can roast gradually while other tasks, like production or cleaning, are completed.
