Common Mistakes to Avoid

- Not Preheating the Oven: Baking in a cold oven can result in undercooked onions and cheese. Always preheat your oven to 375°F (190°C) before placing the dish inside.
- Overcrowding the Dish: Layering too many onion rings can prevent proper baking. Arrange them in a single layer for even cooking and melting cheese.
- Removing Foil Too Early: Taking off the foil too soon may not allow enough time for the cheese to become bubbly and golden. Bake covered for the first 25 minutes.
- Neglecting Cooling Time: Serving immediately can lead to burns or uneven flavors. Allow your Tennessee Onions to cool slightly before serving for the best experience.
