In a sauce pan, boil pasta using the time on the pasta packaging instruction for time needed. Keep the boiled water for the broccoli, so remove pasta only.
Chop broccoli crown into smaller florets. After removing pasta out of the boiling water, place broccoli pieces into the water and cook with lid covered for around 5 minutes or until the broccoli is just tender and holding together well.
Remove broccoli from the water and strain as much of the water out before placing the broccoli into the béchamel sauce. Fold broccoli into the béchamel sauce.
In a square 8x8 or 9x9 pan, lined with tin foil, scoop the béchamel broccoli into the pan evenly. Sprinkle breadcrumbs over the top.
Bake at 350 F for 20 minutes and if needed 5 minutes boiled at 425F until breadcrumb is slightly browned and cheesy sauce on the top is starting to harden. Enjoy after 5 minutes of cooling!
