Gather and prepare your ingredients
Before we start, it's essential to have everything ready. Here’s what you’ll need:
- 3 pounds of Vidalia or sweet onions
- Various spices and cheeses that include kosher salt, dry mustard powder, garlic powder, and smoked paprika among others
- Unsalted butter for richness

Season the onion rings
Once you've sliced your onions crosswise into ¼-inch-thick rings, it’s time to season them. In a large bowl, toss the onion rings with kosher salt, dry mustard powder, garlic powder, smoked paprika, and optional cayenne pepper for a hint of heat. Make sure every ring gets a touch of flavor! This step is crucial because it enhances the natural sweetness of the onions, making your Tennessee onions truly irresistible.
Layering the ingredients in the baking dish
With your onions seasoned, let's layer them into a 9x13-inch baking dish. Start by arranging half of the round rings in an even layer. Then, sprinkle with your choice of mild cheddar and smoked Gouda cheeses—this is where the magic starts. Continue by layering the remaining onions on top, followed by the remaining cheese mixture. The layers create a beautiful, cheesy, and savory dish that’s bound to win hearts!
Baking the casserole (covering and uncovering)
Now, cover the dish with aluminum foil and pop it into a preheated oven at 350ºF. Bake for about 45 minutes, allowing the onions to soften and the casserole to bubble. After that, remove the foil and let it bake for an additional 30 minutes. This step helps achieve that golden-brown, ooey-gooey cheese topping that is so satisfying!
Final touches before serving
Before you serve, sprinkle some finely chopped fresh parsley over the top to brighten up the dish. This little touch adds a fresh flavor and vibrant color, making the dish even more appealing. Let it sit for a few minutes before digging in; patience rewards you with enhanced flavors.
Now you're ready to enjoy your delicious Tennessee onions! Whether as a side dish or part of a festive meal, this recipe is sure to become a favorite.
