Instructions
- Preheat the oven to 350°F (175°C), ensuring optimal temperature for baking.

Notes
- Select sweet Vidalia onions for the most mellow, delicate flavor that melts beautifully during baking.
- Slice onions uniformly to ensure even cooking and consistent texture throughout the dish.
- Choose high-quality cheeses with good melting properties like sharp cheddar and fresh Parmesan for maximum flavor complexity.
- Adjust baking time slightly for crispier or softer onions depending on personal preference, watching cheese browning carefully.
