Ingredients
Scale
Onions and Seasonings
- 3-4 sweet onions, sliced into rings
- 1 teaspoon garlic powder
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
Butter and Cheeses
- 4 tablespoons unsalted butter
- 2 cups shredded cheddar cheese
- 2 cups shredded Italian blend cheese or mozzarella cheese
- 1/2 cup grated parmesan cheese
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9 x 13-inch baking dish thoroughly to prevent sticking.
- Prepare Onions: Peel the sweet onions and slice them into rings. Separate the rings gently and arrange them evenly in the bottom of the prepared baking dish.
- Season the Onions: Evenly sprinkle garlic powder, Italian seasoning, salt, and ground black pepper over the onion rings to infuse them with flavor.
- Add Butter: Place slices of unsalted butter evenly atop the seasoned onions to add richness and help with caramelization during baking.
- Layer Cheeses: Spread the shredded cheddar cheese over the onions, then add the Italian blend or mozzarella cheese, and finally sprinkle the grated parmesan cheese on top for a cheesy crust.
- Bake: Bake the dish in the preheated oven for 25-30 minutes, or until the cheeses are thoroughly melted, bubbly, and lightly golden on top.
- Serve: Remove from the oven and serve warm as a deliciously cheesy and savory side dish.
Notes
- You can substitute Italian blend cheese with mozzarella or any mild melting cheese if preferred.
- For a sharper flavor, consider using sharp cheddar cheese.
- Make sure to slice onions uniformly for even cooking.
- This dish pairs well with grilled meats or as a standalone vegetarian side.
- Use unsalted butter to control salt levels; adjust seasoning accordingly.
