Combine all ingredients until mixed thoroughly. Place in an ovenproof baking or casserole dish.
Bake the Vidalia dip for 25 minutes or until golden brown and bubbling hot!
Serve hot with pita chips, bagel chips, toast rounds, cracker, tortilla chips, veggies, etc.
You can dice or chop your Vidalia onion. Either one will be fine! I do recommend freshly grating your sharp (or extra sharp) white cheddar cheese, it really takes this dip up a notch vs pre-shredded cheese.
