Having these ready will make your cooking process smooth and enjoyable!
Slice and stack the onions
Now, let’s bring those onions to life. Set an onion on its side on a cutting board, and with a sharp knife, slice it into ¼-inch thick rounds. Once you’ve cut through, separate the rounds into individual rings.
Now for the fun part—restack the rings, starting from the largest to the smallest. This step mimics the original shape, helping with cooking and presentation later!
Mix the seasonings
In a small bowl, combine the dried parsley, mustard, garlic powder, seasoned salt, oregano, kosher salt, cayenne, and black pepper. Mixing these spices is vital, as they’ll add layers of flavor to your Tennessee Onions.
Prepare the cheese blend
In a separate medium bowl, blend together the shredded mozzarella, sharp cheddar, and grated Parmesan. This cheesy goodness is going to elevate your dish, making it irresistibly delicious.
Layer and bake the onions
Now, it’s time to bring everything together. Sprinkle your onion rings with the seasoning blend while gently tossing to ensure they are evenly coated. After that, dot the onions with those buttery cubes, and pour the vegetable broth into the bottom of your greased 13” x 9” baking dish. Place your stacked rings in the dish and tightly cover it with aluminum foil.
Bake these beauties in a preheated oven at 350°F for about 75 to 90 minutes. The goal is tender onions—poke them with a fork; they should be easy to pierce!
Broil for that perfect finish
Once your onions are cooked to perfection, remove them from the oven and generously sprinkle the cheese mixture on top. Return them to the oven for an additional 5 to 7 minutes or until the cheese bubbles and turns a lovely golden brown.
Finally, crank your oven to broil! Keep a close eye on them for 1 to 2 minutes until the cheese forms crispy, delicious spots. Just like that, you’ll have Tennessee Onions that are ready to serve with a sprinkle of fresh parsley on top!
With these easy-to-follow steps, preparing Tennessee Onions can be a delightful journey, yielding a mouthwatering side dish that pairs beautifully with any main course. Enjoy your culinary creation!
