- 1 teaspoon salt: Enhances the taste; feel free to adjust to your liking.
- 1 teaspoon garlic powder: Brings a warm, savory depth without overpowering the onions.
- 1/2 teaspoon oregano: Introduces a subtle herbaceous note that complements the cheese.

How to Make Tennessee Onions Recipe
Step 1: Prepare Your Baking Dish and Oven
Start by preheating your oven to 350°F (175°C) and lightly coating a 9×13-inch baking dish with non-stick cooking spray. This simple prep ensures your onions cook evenly and prevents sticking without added hassle.
Step 2: Slice and Separate the Onions
Peel your Vidalia onions carefully, then slice them into ¼ inch rounds. Gently separate these slices into individual rings. This step is crucial because it allows the seasoning and cheese to coat every delicious layer of onion.
Step 3: Season the Onion Rings
Lay the onion rings evenly across the baking dish. Sprinkle salt, garlic powder, and oregano evenly over the top. This seasoning layers in flavor that complements both the sweetness of the onions and the richness of the cheeses.
Step 4: Add Butter for Richness
Cut the unsalted butter into small pats and distribute them over the seasoned onions. As the butter melts during baking, it infuses the dish with that classic, irresistible buttery flavor that transforms simple onions into a comfort food delight.
Step 5: Layer the Cheeses
Sprinkle the Italian blend cheese and cheddar cheese evenly over the onions, followed by the Parmesan cheese. The combination of these cheeses creates a wonderful melty, golden crust with bursts of tang and nuttiness in every bite.
Step 6: Bake Until Golden
Place the dish in your preheated oven and bake for 35-40 minutes. You’ll know it’s ready when the cheese is bubbly and beautifully browned. Serve these warm for the best gooey, flavorful experience.
