  • Salt – Essential for bringing out the full flavors; adjust according to your taste preference.
  • Garlic Powder – Infuses depth and warmth into this comforting dish.
  • Oregano – Brings an aromatic, herbal note that complements the onions beautifully.

For the Cheese Layers

  • Italian Blend Cheese – A melty mix that delivers complexity; use finely shredded for even melting.
  • Cheddar Cheese – Provides a balance of sharpness and creaminess, ensuring a deliciously cheesy topping; finely shredded is ideal for melting.
  • Parmesan Cheese – Contributes a salty, crunchy finish when baked; again, finely shredded is best for optimal results.

With these ingredients, your Tennessee Onions will shine on the table, offering an irresistible cheesy comfort that makes it a must-try side dish.

Step‑by‑Step Instructions for Tennessee Onions

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab a 9×13-inch baking dish and spray it generously with non-stick cooking spray. This will help your Tennessee Onions release easily after baking and prevent them from sticking to the dish.

Step 2: Slice the Onions
Next, take your Vidalia onions and carefully peel away the outer skin. Slice the onions into ¼-inch thick rounds, separating them into individual rings as you go. Aim for uniform thickness to ensure that the onions cook evenly, giving your Tennessee Onions that perfect tender texture.

Step 3: Arrange the Onion Rings
Once the onions are sliced, layer the onion rings evenly across the bottom of the prepared baking dish. As you arrange them, sprinkle salt, garlic powder, and oregano generously over the onions. This seasoning will enhance the sweetness of the onions and bring out the Southern flavors in your Tennessee Onions.

Step 4: Add Butter
Take unsalted butter and cut it into eight equal pats. Place these pats evenly across the surface of the onions, ensuring some butter lands in between the rings. The melting butter will create a rich base as it combines with the sweetness of the onions, contributing to the delightfully cheesy result of your Tennessee Onions.

Step 5: Layer the Cheese
Sprinkle the Italian blend cheese and cheddar cheese over the entire onion layer, making sure to cover all the onions well. Finally, finish with a generous layer of finely shredded Parmesan cheese on top. This three-cheese mixture will create a golden, bubbly crust as the Tennessee Onions bake, enticing everyone around.

Step 6: Bake the Dish
Slide your baking dish into the preheated oven and bake for 35-40 minutes. Keep an eye on the dish; you’re aiming for the cheese to melt completely and turn a lovely golden brown. The aroma of the baking Tennessee Onions will fill your kitchen and heighten your anticipation!

Step 7: Serve and Enjoy
Once baked to perfection, remove your Tennessee Onions from the oven and let them cool for a few moments. Serve your dish hot to maintain that melty texture, and watch as your family or guests delight in this cheesy, savory side dish that embodies pure comfort food.

How to Store and Freeze Tennessee Onions

Fridge: Store any leftovers in an airtight container for up to 3 days. To maintain optimal flavor and texture, ensure they are covered tightly.

Freezer: For longer storage, freeze the cooled Tennessee Onions in an airtight container or freezer bag for up to 3 months. Thaw in the fridge overnight before reheating.

Reheating: When ready to enjoy the leftovers, reheat in the oven at 350°F (175°C) for about 10 minutes until hot and bubbly. This helps restore that comforting cheesy texture!

Make Ahead Options

These Tennessee Onions are perfect for busy home cooks looking to save time without sacrificing flavor! You can prep the onions, cheese, and seasonings up to 24 hours in advance. Simply slice the Vidalia onions and layer them in the baking dish, adding the butter, spices, and cheeses as instructed. Cover the dish tightly with cling film and refrigerate overnight to keep everything fresh. When you’re ready to enjoy your cheesy delight, just pop it in the oven at 350°F (175°C) and bake for about 40 minutes, allowing those delicious flavors to meld beautifully. With this make-ahead option, you’ll have a comforting side dish ready with minimal effort on busy weeknights!

Expert Tips for Tennessee Onions

  • Slice Evenly: Ensure your Vidalia onions are sliced to ¼ inch thick for uniform cooking; this prevents some being overcooked while others remain crunchy.

  • Use Quality Cheese: Opt for finely shredded cheese to guarantee it melts smoothly. Mixing cheese varieties enhances flavor complexity in your Tennessee Onions.

  • Butter Distribution: Place butter pats evenly over the onions before baking; this helps create a rich, creamy base rather than an overly oily top.

  • Watch the Bake Time: Keep an eye on the oven while baking; remove the dish once the cheese is golden and bubbly to avoid burning.

  • Serve Immediately: Tennessee Onions taste best straight out of the oven while hot. If reheating leftovers, cover them to keep moisture and flavor intact.
