Tennessee Onions
This is an old Appalachian recipe that you just have to trust me on - give it a try and you'll be hooked! Sweet onions, flavorful seasonings, and gooey cheese, what's not to love. And although this is a casserole style dish and it's delicious on it's own they're also perfect served on sandwiches, burgers, inside fajitas, on top of steaks, and about a million other ways you're gonna think of when you taste them!

Step 1
Preheat the oven to 350 degrees and lightly coat a 9x13-inch baking dish with cooking spray. In a small dish combine all the seasonings, set aside. Separate the onion rings and place them in a large bowl and drizzle with 1 tbsp melted butter, use your hands to coat the onions with the butter, then add the spice mix, again using your hands to toss and coat all the onions well.

Step 2
Place half of the onions in an even layer in the baking dish. Sprinkle with 2 ounces of each of the shredded cheeses (about 1/2 cup each)
Arrange the remaining onions on top and sprinkle with the remaining 2 ounces of each shredded cheese, then sprinkle evenly with Parmesan cheese. Dot the top of the dish with 4 tablespoons diced butter.

Step 3
Cover the baking dish with aluminum foil and bake until the onions are softened and the casserole is bubbling, about 45 minutes. Uncover and bake until the cheese on top is melted and browned in spots, about 30 minutes more. I also like to put mine under the broiler for a couple minutes to really brown up the top, but watch it closely if you do this. Sprinkle with chopped fresh parsley leaves if desired.
Note
I've seen a lot of different ways to make this dish on the internet and I've looked at quite a few recipes for this dish, too. I just combined everything I liked from a number of these places, left out what I didn't like, and added a little brown sugar twist of my own and we just loved these! I will say they are best served right out of the oven but they keep well for a few days and I've reheated them in a skillet on the stove top and in the air fryer and they taste pretty good like that, too.
