Ingredients
Onions
- 3-4 Vidalia sweet onions
Seasonings and Butter
- 4 tablespoons unsalted butter
- 1 teaspoon salt (adjust according to preference)
- 1 teaspoon garlic powder
- 1/2 teaspoon oregano
Cheeses
- 1 cup Italian blend cheese, finely shredded
- 1 cup cheddar cheese, finely shredded
- 1/2 cup Parmesan cheese, finely shredded
Instructions
- Preheat and Prepare Dish: Preheat your oven to 350°F (175°C) and coat a 9×13-inch baking dish with non-stick cooking spray to prevent sticking and ensure easy cleanup.
- Prepare Onions: Peel the Vidalia sweet onions carefully and slice them into ¼ inch thick rounds. Gently separate the rounds into individual rings.
- Arrange and Season: Spread the onion rings evenly across the prepared baking dish. Sprinkle the salt, garlic powder, and oregano evenly over the onions to season them thoroughly.
- Add Butter: Cut the unsalted butter into small pats and distribute them evenly over the layered onion rings to add richness and help with caramelization during baking.
- Add Cheese Layers: Sprinkle the finely shredded Italian blend cheese and cheddar cheese evenly over the buttered onions, then finish by sprinkling the Parmesan cheese on top for a flavorful crust.
- Bake: Place the dish in the preheated oven and bake for 35-40 minutes until the cheese is melted, bubbly, and browned, and the onions are tender. Serve warm for the best flavor and texture.
Notes
- Use Vidalia sweet onions for their natural sweetness and mild flavor, which complement the cheesy topping perfectly.
- Adjust salt to taste, especially since the cheeses can add saltiness.
- For a sharper flavor, consider adding a pinch of black pepper or smoked paprika.
- Make sure to separate the onion rings gently to ensure even cooking.
- This dish pairs well with grilled meats, poultry, or as a hearty vegetarian main side.
