How to Make Tennessee Onions
Phase 1 – Prep
STEP 1. Preheat the oven. Set your oven to 350 degrees Fahrenheit.
STEP 2. Prepare the baking dish. Grease a 9×13-inch baking dish with non-stick cooking spray.
STEP 3. Prepare the onions. Peel and slice 3 large sweet onions into ¼-inch thick slices and separate the rings into a large bowl.
STEP 4. Season the onions. Sprinkle with garlic powder, Italian seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Gently toss to combine.
Phase 2 – Cook
STEP 5. Layer the ingredients. Place the seasoned onions in the prepared baking dish, topping with small pieces of butter.
STEP 6. Add the cheeses. Evenly layer shredded cheddar cheese, shredded mozzarella cheese, and shredded Parmesan cheese over the onions.
STEP 7. Cover and bake. Cover the pan with foil and bake for 30 minutes.
STEP 8. Uncover and finish baking. Remove the foil and bake for another 30 minutes, until the cheese is golden and bubbly.
Why This Recipe Works
The delightful balance of textures and flavors results from the way the onions caramelize and the cheeses melt. The initial baking traps steam, softening the onions, while the subsequent uncovered baking allows the tops to crisp and bubble deliciously. The spices infuse every layer with their unique character, ensuring that each forkful is both juicy and satisfying. The baking method also enhances the sweetness of the onions, creating a delightful contrast to the rich, savory cheeses.

- Let the dish sit for a few minutes post-baking to allow the cheese to set slightly.
- Experiment with adding cooked bacon or sautéed mushrooms for extra complexity.
