Sprinkle crushed croutons over the top of the broccoli. Place lid on the oven. Bake at 350F by placing 9 hot charcoals in a circle to fit underneath the 12-inch Dutch oven. Place 15 charcoals around the outside edge of the lid. Bake for 20 minutes. Rotate lid clockwise and oven counterclockwise. Check every 10 minutes. When croutons are golden brown and sauce is bubbling, remove from heat.
