Ingredients

• 3-4 Vidalia sweet onions – These onions are known for their natural sweetness, which caramelizes beautifully in the oven.
• 4 tablespoons unsalted butter – Adds richness and depth to the dish.
• 1 teaspoon salt – Adjust to taste, depending on how salty your cheese blend is.
• 1 teaspoon garlic powder – Provides a savory undertone without overpowering the sweetness of the onions.
• ½ teaspoon oregano – Adds a subtle herb flavor to complement the onions and cheese.
• 1 cup Italian blend cheese, finely shredded – This cheese mix typically contains mozzarella, Parmesan, and other cheeses that melt beautifully.
• 1 cup cheddar cheese, finely shredded – Sharp cheddar adds a bold, tangy flavor.
• ½ cup Parmesan cheese, finely shredded – Parmesan helps to create a golden, crispy top layer.

How to Make Tennessee Onions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). While the oven heats up, coat a 9×13-inch baking dish with non-stick cooking spray to prevent sticking and ensure easy cleanup.

Step 2: Slice the Onions

Take 3-4 Vidalia sweet onions, peel them, and slice them into ¼-inch thick rounds. Carefully separate the rounds into individual onion rings. These rings will form the base layer of your dish.

Step 3: Season the Onions

Spread the onion rings evenly across the bottom of your prepared baking dish. Sprinkle salt, garlic powder, and oregano evenly over the onions. These seasonings will enhance the natural sweetness of the Vidalia onions.

Step 4: Add Butter

Slice the unsalted butter into roughly eight pats and scatter them across the onion rings. As the dish bakes, the butter will melt, creating a rich and flavorful base for the cheese to meld into.

Step 5: Layer the Cheeses

Now for the best part—cheese! Sprinkle 1 cup of Italian blend cheese and 1 cup of cheddar cheese evenly across the onions. Finish with a ½ cup of shredded Parmesan cheese on top to give the dish a crispy, golden finish.

Step 6: Bake Until Golden and Bubbling

Place the dish in the oven and bake for 35-40 minutes until the cheese is golden brown and bubbling. If you prefer a crispier top, you can broil the dish for the last 2-3 minutes of baking.

Step 7: Serve Hot

Remove the Tennessee Onions from the oven and serve them promptly. This dish is best enjoyed warm, with the cheese perfectly melted and the onions tender but still retaining a bit of bite.

Tips for Perfect Tennessee Onions

• Onion Choices: Vidalia onions are recommended for this recipe because of their sweetness, but if you can’t find them, any sweet onion variety will work.
• Customizable Cheeses: While the recipe calls for a mix of Italian blend, cheddar, and Parmesan, feel free to experiment with your favorite cheeses. Gruyère or provolone would also taste fantastic!
• Make It a Main: Want to turn this into a hearty main dish? Add some crumbled bacon or cooked sausage before layering on the cheese.
