Ingredients
Ingredients
- Sweet onions (Vidalia or yellow), sliced ½ inch thick
- Butter, cut into small pats
- Italian seasoning
- Salt and pepper
- Shredded mozzarella cheese
- Provolone cheese, sliced
- Grated Parmesan cheese
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) and lightly butter a baking dish to prevent sticking and add richness to the dish.
- Arrange Onions: Lay the thick ½ inch slices of sweet onion in a single layer arranged evenly in the prepared baking dish, ensuring good coverage to maximize flavor absorption.
- Season and Butter: Season the onion slices evenly with salt, pepper, and Italian seasoning. Dot the onions with small pats of butter to add moisture and enhance the richness as they bake.
- Add Cheese Layers: Sprinkle shredded mozzarella cheese evenly over the onions, then layer slices of provolone cheese on top. Finally, finish with a generous topping of grated Parmesan cheese for a sharp, nutty flavor.
- Bake the Dish: Bake uncovered in the preheated oven for 25 to 30 minutes until the cheese is melted, golden, bubbly, and the onions are tender.
- Optional Broil: For extra crispiness and golden color on the cheese topping, place the dish under the broiler for 2 minutes, watching carefully to prevent burning.
- Rest and Serve: Allow the baked onions to rest for 5 minutes after removing from the oven, so the cheese sets slightly and flavors meld before serving.
Notes
- Using sweet onions such as Vidalia enhances the natural sweetness and reduces sharpness.
- Adjust the amount of Italian seasoning to taste for desired herb intensity.
- Optional broiling adds a nice crispy top but is not required.
- Serve as a side dish with grilled meats, sandwiches, or alongside a salad.
- Leftovers can be refrigerated and gently reheated.
