I love garlic Parmesan flavor in almost everything.  If you love big flavors, but not a fan of hot and spicy dishes, this is for you.


Since my family is not an onion fan, I replaced it with celery ribs.  If you choose to use onions, use 2 medium size or 1 big yellow onion and cut into wedges.

If pork loin is not cooked through after checking with meat thermometer, cover it back with foil and cook it again in the oven with 15 minutes increment until meat is cooked.
