Description
Sweet onions baked with layers of mozzarella, provolone, and Parmesan for a golden, melty side dish full of rich, savory flavor.
Ingredients
→ Produce:
2 large sweet onions (Vidalia or yellow), sliced ½ inch thick
→ Dairy:
4 tablespoons unsalted butter, cut into small pats
1 cup shredded mozzarella cheese
4 slices provolone cheese
¼ cup grated Parmesan cheese
→ Seasonings:
1 teaspoon Italian seasoning
½ teaspoon salt
¼ teaspoon black pepper
Instructions
Preheat oven to 375°F. Lightly butter a baking dish.
Arrange onion slices in a single, even layer in the dish.
Season onions with salt, black pepper, and Italian seasoning. Dot with pats of butter.
Sprinkle shredded mozzarella over onions, layer provolone slices, and top with grated Parmesan.
Bake uncovered for 25–30 minutes, until the cheese is golden and bubbly.
For a crispy top, broil for 2 minutes, watching carefully.
Let rest for 5 minutes before serving to allow cheese to set.
Notes
Add red pepper flakes for a spicier twist.
Try other cheeses like Gruyère, fontina, or gorgonzola for variety.
Substitute shredded provolone for slices if needed.
Avoid overcrowding onions for best texture; use a larger dish or bake in batches.
Best served immediately. Store leftovers in the fridge for up to 3 days.
