How to Make Tennessee Onions
-
Prepare Onions: Peel and cut the sweet Vidalia or yellow onions into thick (½ inch) slices, ensuring the onion rings stay intact. This provides the best texture once baked.
-
Preheat Oven: Preheat your oven to 375°F (190°C). While it’s heating, butter a casserole dish or a 9×13-inch pan to ensure a non-stick surface.
-
Arrange Onions: Carefully lay the onion slices in a single layer in the prepared dish. They should touch but not stack, allowing for even baking and caramelization.
-
Season Onions: Generously sprinkle with salt, pepper, and Italian seasoning to enhance flavor. Dot the onion surface with pats of butter for added richness.
-
Layer Cheese: Start by adding a layer of shredded mozzarella cheese, followed by provolone. Finish with a generous topping of grated Parmesan cheese for that delightful crispy finish.
-
Bake: Place the dish in the oven, baking uncovered for 25-30 minutes until it’s bubbly and golden brown. For an extra crunchy top, broil for an additional 2 minutes, keeping a close eye to prevent burning.
-
Rest Before Serving: Allow the dish to rest for about 5 minutes before serving. This helps the cheese set and makes for easier serving.
Optional: Garnish with fresh herbs for an added touch of flavor and color.

Tennessee Onions Recipe FAQs
What type of onions should I use for Tennessee Onions?
I recommend using sweet Vidalia or yellow onions for the best flavor. They’re naturally sweeter and caramelize beautifully when baked. Avoid red onions, as they have a stronger taste and can change color during cooking.
How should I store leftover Tennessee Onions?
Store leftover Tennessee Onions in an airtight container in the refrigerator for up to 3 days. This will keep them fresh and flavorful. When you’re ready to indulge again, reheat them in the oven at 350°F (175°C) for about 10 minutes to maintain that crispy cheese topping.

If your dish turns out watery, this could be due to using excess moisture in the onions.

Also, consider pre-cooking the onions lightly in a skillet before layering them in the dish.
