Instructions

Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick cooking spray to prevent sticking and ensure easy cleanup.
Prepare Onions: Peel the Vidalia onions and slice them into ¼ inch thick rounds. Carefully separate these rounds into individual rings to allow even cooking and seasoning.
Season Onions: Spread the onion rings evenly in the prepared baking dish. Sprinkle salt, garlic powder, and oregano evenly over the onions to infuse them with savory flavor.
Add Butter: Cut the unsalted butter into small pats and distribute them evenly on top of the seasoned onion rings to add richness and enhance browning during baking.
Top with Cheese: Sprinkle the Italian blend cheese and cheddar cheese over the buttered onions, followed by an even layer of Parmesan cheese to create a deliciously cheesy crust.
Bake: Place the dish in the oven and bake for 35-40 minutes, or until the cheese is browned, bubbling, and slightly crispy on top. Serve the Tennessee Onions warm as a savory side dish.

Notes

You can adjust the amount of salt to suit your taste.
For a sharper flavor, try mixing different types of cheddar or adding smoked cheese.
Use fresh herbs like thyme or rosemary for a different aromatic profile.
Make sure to separate onion rings fully to allow even cooking and thorough seasoning.
Serving warm ensures the cheese remains melty and the onions tender.
