Ingredients
- 3–4 sweet onions Vidalia or yellow, sliced ½ inch thick
- 4 tablespoons butter cut into small pats
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
- 1 cup shredded mozzarella cheese
- 4 slices provolone cheese
- ¼ cup grated Parmesan cheese
Instructions
- Preheat the oven to 375°F (190°C) and lightly butter a baking dish. Peel and slice sweet onions into ½-inch thick rounds, keeping each ring stack intact.
- Arrange them in a single layer in the dish, then season with salt, pepper, and Italian seasoning. Add small pats of butter over each slice.
- Top with mozzarella, then lay provolone slices across the onions. Sprinkle Parmesan on top for a crispy, savory finish.
- Bake uncovered for 25–30 minutes, until the cheese is golden and bubbling and the onions are tender. For extra crispness, broil for 1–2 minutes. Let rest for 5 minutes before serving.
