Step-by-Step Directions for Tennessee Onions
Preheat the oven: Start by arranging a rack in the center of your oven and preheating it to 350 degrees Fahrenheit (175 degrees Celsius). Lightly grease a 13-inch by 9-inch baking dish with cooking spray to ensure easy removal later.
Prepare the onions: Cut the sweet Vidalia onions into 1/4-inch thick rounds and gently separate the rounds into individual rings. Restack the rings in the prepared baking dish, creating a beautiful layered effect.
Mix the spices: In a small bowl, combine the dried parsley, dry mustard, garlic powder, seasoned salt, oregano, kosher salt, cayenne pepper, and black pepper. In a separate medium bowl, toss together the mozzarella, cheddar, and Parmesan cheeses until well mixed.
Season the onions: Sprinkle the seasoning blend over the onion rings, gently tossing to ensure they’re evenly coated. Dot the onion mixture with pieces of butter for added richness. Pour 1/2 cup of water into the bottom of the pan, then cover tightly with foil.
Bake the onions: Place the dish in the oven and bake until the onions are tender, which will take about 75 to 90 minutes. You’ll know they are ready when they can be easily pierced with a fork.
Add the cheese: Once the onions are tender, remove the dish from the oven and sprinkle the cheese mixture generously over the top.
Melt the cheese: Return the dish to the oven and bake uncovered for an additional 5 to 7 minutes until the cheese is melted and bubbling appetizingly.
Broil for perfection: Turn on the broiler and broil the dish for about 1 to 2 minutes, or until the cheese is beautifully browned in spots for that perfect finish.
Garnish and serve: Remove the dish from the oven and sprinkle with chopped fresh parsley before serving. The vibrant green adds a lovely touch and a hint of freshness.
