Tennessee Onions is a savory, cheesy baked onion dish that’s a perfect side for any meal. The sweetness of Vidalia onions pairs beautifully with the richness of butter and a blend of cheeses, making it a comforting, flavorful option for family dinners or gatherings. It’s simple to prepare and bakes up golden and bubbly.
Ingredients:
- 3-4 sweet onions (Vidalia recommended)
- 4 tablespoons butter
- 1 teaspoon salt, or to taste
- 1 teaspoon garlic powder
- 1/2 teaspoon oregano
- 1 cup shredded Italian blend cheese
- 1 cup shredded cheddar cheese
- ½ cup shredded Parmesan cheese
Step 1: Prepare the Onions
Preheat your oven to 350°F (175°C). Peel the sweet onions and slice them into ½-inch thick rings. Separate the rings and set them aside.
Step 2: Arrange the Onions
Grease a baking dish (9×13 inch works well) with a little butter or non-stick spray. Arrange the onion rings in the dish in an even layer, slightly overlapping them if needed. This will help them bake evenly and soak up the cheese and butter.
Step 3: Add Butter and Seasonings
Melt the butter in a small saucepan or microwave. Drizzle the melted butter evenly over the onion slices. Sprinkle the salt, garlic powder, and oregano over the onions, ensuring each layer is seasoned well.
Step 4: Add the Cheeses
Next, sprinkle the shredded Italian blend cheese, cheddar cheese, and Parmesan cheese evenly over the onions. Be generous with the cheese, as it melts into the onions and creates a rich, gooey topping.
Step 5: Bake the Onions
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil and continue baking for another 15-20 minutes, or until the cheese is golden brown and bubbly, and the onions are tender.
Step 6: Serve and Enjoy
Once the onions are done baking, remove them from the oven and let them cool for a few minutes before serving. These Tennessee Onions can be served as a side dish with grilled meats, chicken, or even as a topping for burgers or steaks.
Cooking Notes:
- Onion Choice: Vidalia onions are recommended for their sweetness, but you can use any sweet onion variety. If you prefer a sharper flavor, yellow onions can also work.

- Herbs: Oregano adds an earthy flavor, but you can also try thyme or rosemary for a different twist.
Variations:
- Spicy Tennessee Onions: Add 1/4 teaspoon of crushed red pepper flakes to the seasoning for a spicy kick.
- Bacon Tennessee Onions: Sprinkle cooked, crumbled bacon over the onions before baking for a smoky, savory addition.
- Creamy Tennessee Onions: Mix 1/2 cup of heavy cream or sour cream with the melted butter before pouring it over the onions for an extra rich and creamy texture.
