Step‑by‑Step Instructions for Tennessee Onions

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) while you prepare a 9×13-inch casserole dish. Generously butter the sides and bottom of the dish to ensure easy release of your Tennessee Onions once baked. This will create a lovely golden finish and enhance the flavors as they cook.

Step 2: Slice the Onions
Peel and slice the sweet onions into ½-inch thick rings. Lay the rings flat in a single layer within the prepared casserole dish. Arrange them evenly so that every bite of these Tennessee Onions is filled with sweet, tender goodness.

Step 3: Season the Onions
Sprinkle the sliced onions with salt, pepper, and Italian seasoning for a burst of flavor. Then, dot the onions with small pats of butter, ensuring they’re well-coated to achieve a rich taste. This step is key to enhancing the natural sweetness of the onions while they bake.

Step 4: Add Cheese Layers
Layer the shredded mozzarella and provolone cheese generously over the seasoned onions. This melty, cheesy topping will bring out the best in your Tennessee Onions. Follow this with a hearty sprinkle of grated Parmesan cheese on top, which will form a crispy, golden crust during baking.

Step 5: Bake Uncovered
Place the casserole dish in the preheated oven and bake uncovered for 25-30 minutes. You’ll know it’s ready when the cheese is bubbling and lightly browned, giving you that delicious, savory aroma. If you desire an extra crispy top, broil for 2 minutes while carefully monitoring to avoid burning.

Step 6: Let Rest and Serve
Once baked to perfection, remove the dish from the oven and let it rest for 5 minutes. This resting time allows the cheese to set slightly, making it easier to serve. Scoop out portions of these delightful Tennessee Onions to enjoy a flavorful and cheesy side that everyone will love!
