Cut the butter into roughly eight even portions or pats. Distribute these butter pats evenly across the seasoned onion rings in the baking dish.
Sprinkle the Italian blend cheese and cheddar cheese evenly over the onion rings. Finish with a final topping of shredded Parmesan cheese.
Place the baking dish into the preheated oven. Bake for 35-40 minutes until the cheese is browned and bubbling.
For optimal taste, serve the dish promptly while it remains warm
NOTE:
Italian blend cheese is a cheese that contains a mixture of two or more types of cheese. A traditional
Italian cheese blend often includes a mix of Mozzarella, Parmesan, Romano, Asiago, and Provolone.
