Ingredients
Scale
Onions and Seasoning
- 3-4 Vidalia sweet onions
- 1 teaspoon salt (adjust according to preference)
- 1 teaspoon garlic powder
- 1/2 teaspoon oregano
Cheese
- 1 cup Italian blend cheese, finely shredded
- 1 cup cheddar cheese, finely shredded
- 1/2 cup Parmesan cheese, finely shredded
Butter
- 4 tablespoons unsalted butter
Instructions
- Preheat the oven: Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by coating it with non-stick cooking spray to prevent sticking.
- Prepare the onions: Clean and peel the Vidalia sweet onions. Slice them into ¼ inch thick rounds and gently separate these slices into individual rings.
- Arrange and season: Spread the onion rings evenly across the baking dish. Sprinkle the salt, garlic powder, and oregano over the onions evenly for balanced seasoning.
- Add butter: Cut the unsalted butter into small pats and distribute them evenly over the seasoned onions to add richness and promote browning during baking.
- Layer the cheeses: Sprinkle the finely shredded Italian blend cheese and cheddar cheese evenly over the onions, followed by a final layer of Parmesan cheese to create a melty, flavorful topping.
- Bake: Place the baking dish in the oven and bake for 35-40 minutes, or until the cheese topping is browned and bubbling, indicating the dish is fully cooked and flavorful.
- Serve warm: Remove from oven and serve immediately while warm for the best taste and texture.
Notes
- Vidalia onions are preferred for their natural sweetness, but any sweet onion variety can be used.
- Adjust salt according to your taste preference or dietary needs.
- For a sharper flavor, use a sharper cheddar or add a bit of cayenne pepper.
- This dish can be prepared ahead and baked just before serving.
- Leftovers can be stored in the refrigerator and reheated gently in the oven.
