Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.

Step 2: Slice the Onions

Peel the Vidalia onions and slice them into 1/4-inch thick rings. Separate the rings and layer them evenly in the prepared baking dish.

Step 3: Mix the Seasoning

In a small bowl, mix together the melted butter, garlic powder, onion powder, smoked paprika, salt, and pepper.

Step 4: Assemble the Dish

Pour the seasoned melted butter evenly over the onion slices, making sure to coat all layers. Sprinkle the mozzarella and cheddar cheeses over the top.

Step 5: Bake to Perfection

Cover the dish loosely with foil and bake for 30 minutes. Then, remove the foil and continue baking for another 15-20 minutes or until the cheese is bubbly and golden brown.

Step 6: Garnish and Serve

Remove from the oven, let cool slightly, and garnish with fresh chopped parsley if desired. Serve warm as a decadent side dish or comforting snack.
