Step 1: Prep the Onions

Preheat your oven to 375°F (190°C). Peel the onions and slice them into thick rounds, about 1/2 inch thick. Gently separate the rings and arrange them in a large greased baking dish, stacking if needed.

Step 2: Season Generously

In a small bowl, combine melted butter with garlic powder, onion powder, smoked paprika, salt, and pepper. Drizzle this mixture evenly over the onion rings, ensuring good coverage for full flavor infusion.

Step 3: Add the Cheese

Sprinkle the mozzarella, cheddar, and parmesan cheeses over the onions. Be generous—you want every layer to catch some gooey richness.

Step 4: Bake to Perfection

Cover the baking dish loosely with foil and bake for 25 minutes. Remove the foil and continue baking for another 15–20 minutes, until the cheese is bubbly and golden-brown and the onions are tender.

Step 5: Garnish and Serve

Sprinkle freshly chopped parsley on top for a burst of color and freshness. Serve hot and enjoy this comforting twist on a Southern classic.
