Tennessee Onions Ingredients
For the Onions
• Vidalia sweet onions – Their natural sweetness and tender texture make them the star of this cheesy dish; yellow onions can be used but may alter the flavor profile.
• Unsalted butter – Adds richness and moisture, ensuring each bite melts in your mouth; be cautious with salted butter to maintain the right salt balance.
• Salt – Enhances the overall flavor; feel free to adjust according to your taste preferences.
• Garlic powder – Delivers a subtle garlic kick; using freshly minced garlic provides a burst of freshness.
• Oregano – This herb offers an Italian touch that beautifully complements the sweet notes of the onions.
For the Cheesy Topping
• Italian blend cheese – A delightful mix of cheeses for gooey texture and flavor; alternatives like Gruyere or Fontina can be a tasty swap.
• Cheddar cheese – Adds a sharp, creamy layer that enhances the overall taste; other melty cheeses can also work if you prefer a different flavor.
• Parmesan cheese – Provides a savory, nutty finish to the dish; Pecorino Romano can be used for a sharper twist.
Step‑by‑Step Instructions for Tennessee Onions
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures even cooking and optimal melting of the cheese. While the oven warms up, you can prepare your baking dish and other ingredients, setting the stage for delicious Tennessee Onions.
Step 2: Prepare the Baking Dish
Coat a 9×13-inch baking dish with a light layer of non-stick cooking spray. This will prevent the tasty Tennessee Onions from sticking to the dish as they bake. Make sure to cover the entire surface evenly for easy serving later.
Step 3: Slice the Onions
Take your Vidalia sweet onions and slice them into ¼-inch thick rounds, keeping the rings intact for a lovely presentation. This consistency will ensure that the onions cook evenly, maintaining their texture while becoming sweet and tender as they bake.
Step 4: Arrange the Onions
Lay the sliced onion rounds in the prepared baking dish, arranging them in a single layer. Sprinkle salt, garlic powder, and oregano over the onions to enhance their natural sweetness. These seasonings will complement the rich flavor profile of your Tennessee Onions.
Step 5: Add Butter
Cut unsalted butter into small pats and distribute them evenly across the onion layers. This addition will infuse the onions with richness as they bake, creating a delightful buttery flavor that pairs beautifully with the onions and cheese.
Step 6: Layer the Cheeses
Start layering the cheeses by sprinkling a generous amount of the Italian blend cheese evenly over the onions. Follow this with a layer of cheddar cheese, ensuring the mixture is well-covered. Finally, finish with grated Parmesan cheese for a savory, nutty touch that melts perfectly.
Step 7: Bake Until Golden
Place the baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on the mix as the cheese begins to melt and turn golden-brown. You’re looking for a bubbly, gooey layer on top and tender onions beneath, signaling that your Tennessee Onions are ready to be enjoyed.
Step 8: Cool and Serve
Once cooked, remove the dish from the oven and let it cool for a minute. This brief cooling period enhances the flavors and lets the cheese settle, making each serving of Tennessee Onions easy to dish out. Serve warm and relish the cheesy comfort!
