Preparing Tennessee Onions
When you're ready to dive into the world of Tennessee Onions, it's all about preparation and technique. Let’s walk through the steps together for a delicious outcome that’ll impress your friends and family.
Gather Your Cooking Tools
First things first—get all your tools in place. You’ll need:
- A reliable cutting board and sharp knife
- A 13” x 9” baking dish
- A small bowl for mixing the seasonings
- A medium bowl for combining the cheese
- Aluminum foil
- A broiler-safe oven mitt
Ensuring you have everything handy can save you from those annoying last-minute scrambles.
Preheat the Oven and Prepare the Dish
Now, let’s get your oven ready. Arrange a rack in the center and preheat it to 350°F (175°C). While it's heating up, lightly grease your baking dish with cooking spray; this step will help prevent sticking and make for an easy cleanup after enjoying your wonderful Tennessee Onions.
Preparing the Onions for Baking
On to the star of the show—our sweet Vidalia onions! Place an onion on its side and make vertical slices to create ¼" thick rounds. Once you have those beautiful rings, separate them into individual pieces, and restack them in the dish, starting from biggest to smallest. Repeat with your remaining onions—each stack should feel like a cozy little onion family ready for baking.
Mix the Seasoning Blend
In a small bowl, combine the following seasonings:
- 1 tsp. dried parsley
- 1 tsp. dry mustard
- 1 tsp. garlic powder
- ¾ tsp. seasoned salt
- ½ tsp. dried oregano
- ½ tsp. kosher salt
- ¼ tsp. cayenne pepper
- ¼ tsp. freshly ground black pepper
Feel free to get creative! Maybe add a pinch of something you love.
Layer the Onions and Add the Cheese
Next, gently sprinkle the seasoning blend over the stacked onions and toss them to coat evenly. Dot the onions with cubes of butter for that luscious flavor. Then, in a separate bowl, mix together your cheese: 1 cup each of shredded mozzarella and sharp cheddar, along with ½ cup of Parmesan. Add a splash of low-sodium vegetable broth to the bottom of your baking dish and tightly cover it with aluminum foil.
Bake to Perfection
Pop your Tennessee Onions into the oven and bake for 75 to 90 minutes. You’ll know they’re ready when they easily yield to a fork or cake tester.
Broil for That Perfect Finish
Finally, remove the foil and sprinkle that glorious cheese mixture on top. Return to the oven for an additional 5 to 7 minutes until the cheese is melted and bubbling. Then, turn on the broiler, keeping a close eye—you just need 1 to 2 minutes for a beautiful golden finish.
And, voila! Your Tennessee Onions are ready to shine at your dinner table. These caramelized, cheesy, and savory beauties redefine what it means to enjoy onions. Serve them with freshly chopped parsley for an aesthetic touch!
