How to Make Tennessee Onions – The Cheesy Baked Side

Step 1: Prep Your Oven and Baking Dish

Preheat your oven to 375°F (190°C) and lightly butter your baking dish. This simple step ensures your onions won’t stick and gives a buttery base that melts into the dish for added flavor and a golden crust.

Step 2: Arrange the Onion Slices

Slice your sweet onions about half an inch thick for the perfect balance between sturdiness and tenderness. Lay them out in a single layer in the baking dish to allow even cooking and maximum caramelization potential.

Step 3: Season Brilliantly

Sprinkle the sliced onions generously with salt, pepper, and Italian seasoning. The seasoning brings out the onion’s natural sweetness and layers in a beautifully aromatic touch that pairs perfectly with the cheeses.

Step 4: Add Butter and Cheese Layers

Dot small pats of butter across the onions to melt into every nook and cranny. Then, sprinkle shredded mozzarella first, layer the provolone slices over that, and finish with a dusting of grated Parmesan cheese. This layering is what gives Tennessee Onions – The Cheesy Baked Side its luscious, melty texture and irresistible flavor.

Step 5: Bake and Finish

Bake the dish uncovered for 25 to 30 minutes, allowing the onions to soften, and the cheese to melt and bubble joyously. For an extra crispy topping, set your oven to broil for the last 2 minutes—watch closely so it doesn’t burn! Let the dish rest for at least 5 minutes to firm up slightly before serving.
