Step‑by‑Step Instructions for Tennessee Onions

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven is warming up, lightly butter a 9×13-inch casserole dish to ensure that your cheesy baked Tennessee onions won’t stick. The aroma of melting butter will soon fill your kitchen as we get ready to transform those sweet onions into a delicious side dish!

Step 2: Prepare the Onions
Peel the sweet onions—Vidalia or yellow work best—and slice them into ½ inch thick rounds, carefully keeping the rings intact. Arrange the onion slices in a single layer within the buttered casserole dish. As you layer them, you’ll notice how their natural sweetness will create a beautiful base for your rich cheese layers.

Step 3: Season to Perfection
Sprinkle the onion layers generously with salt, pepper, and Italian seasoning to enhance their wonderful flavors. Next, place small pats of butter evenly over the seasoned onions, allowing it to melt and infuse throughout while baking. This step is key to achieving that tender, melt-in-your-mouth texture expected from Tennessee onions.

Step 4: Add Cheese Layers
Now it’s time to layer in the cheese! Begin by covering the seasoned onions with a generous amount of shredded mozzarella, followed by slices of provolone. Finally, sprinkle grated Parmesan cheese over the top, creating a glorious cheesy crust that will become bubbling and golden during baking. The combination of cheeses will take your Tennessee onions to mouthwatering heights.

Step 5: Bake Until Golden
Place the casserole dish in the preheated oven and bake uncovered for 25 to 30 minutes. Watch as the cheese begins to bubble and turn a lovely golden color, indicating that your cheesy baked Tennessee onions are nearly ready to serve. If you prefer a crispier top, consider broiling for an additional 2 minutes at the end.

Step 6: Rest and Serve
Once baked, remove the dish from the oven and allow the cheesy Tennessee onions to rest for about 5 minutes. This will help the cheese to set and make serving easier. As you slice through the layers, you’ll reveal tender, sweet onion rings enveloped in ooey-gooey cheese—perfect for any meal!

Make Ahead Options

These Cheesy Baked Tennessee Onions are perfect for meal prep enthusiasts looking to save time in the kitchen! You can slice and season the sweet onions up to 24 hours in advance and store them in an airtight container in the refrigerator to maintain their freshness. Additionally, you can layer all the cheeses ahead of time, but it’s best to add the final cheese layer just before baking to ensure a crispy topping. When you’re ready to serve, simply preheat your oven and bake the dish for 25-30 minutes until bubbly and golden. This way, you’ll enjoy delicious, comforting Tennessee Onions with minimal effort and more time with your loved ones!
