2. Season: Sprinkle with garlic powder, Italian seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Gently toss to combine.
3. Add Butter and Cheese: Place the onions in the baking dish and top with butter, cut into small pieces. Then, top with cheddar cheese, shredded mozzarella cheese, and shredded Parmesan cheese.
4. Bake: Cover the pan with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for another 30 minutes, until the cheese is golden and bubbly.
