Choosing the Best Ingredients

The secret to amazing Tennessee Onions lies in quality ingredients. Here’s what you need:

1. Sweet Onions

The best choice is Vidalia onions because they are naturally sweet and mild. If you can’t find Vidalias, you can substitute:

• Walla Walla onions – Similar sweetness.
• Maui onions – A great alternative with a tropical twist.
• Texas Sweet onions – Slightly stronger but still delicious.

2. Butter

Butter is essential for creating that rich, caramelized flavor. Use unsalted butter so you can control the seasoning. If you love an extra buttery taste, don’t be afraid to add a little more!

3. Cheese

A combination of cheeses works best for maximum meltiness and flavor. The best options are:

• Cheddar cheese – Sharpness adds depth.
• Mozzarella cheese – Creates a gooey texture.
• Parmesan cheese – Adds a salty, nutty finish.

4. Seasonings

To elevate the dish, use:

• Garlic powder – Adds depth without overpowering the onions.
• Paprika – Brings warmth and slight smokiness.
• Salt & Pepper – Enhances the natural sweetness of the onions.

5. Optional Additions

• Breadcrumbs – For a crispy topping.
• Bacon bits – Adds a smoky, savory crunch.
• Fresh herbs – Chopped parsley or thyme adds color and freshness.

Step-By-Step Recipe for Tennessee Onions

Ingredients:

• 2-3 large sweet onions (Vidalia, Walla Walla, or Maui)
• 1/2 cup (1 stick) butter, melted
• 1 cup shredded cheese (cheddar, mozzarella, or a blend)
• 1/2 cup Parmesan cheese, grated
• 1/2 teaspoon garlic powder
• 1/2 teaspoon paprika
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

Instructions:

Step 1: Preheat the Oven

Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Slice the Onions

Peel and slice the onions into thick rings (about 1/4-inch thick). Separate the rings and discard the smaller inner pieces if you prefer larger rings.

Step 3: Arrange the Onions

Lay the onion rings evenly in the prepared baking dish, making sure they slightly overlap for better texture and caramelization.

Step 4: Add Butter and Seasonings

Drizzle the melted butter over the onions, ensuring they’re well-coated. Sprinkle garlic powder, paprika, salt, and black pepper evenly over the onions for balanced flavor.

Step 5: Add Cheese

Generously top the onions with shredded cheese and Parmesan, making sure every bite gets a cheesy layer.

Step 6: Bake to Perfection

Cover the dish loosely with foil and bake for 30 minutes. Then, remove the foil and bake for another 15 minutes, allowing the cheese to turn golden brown and slightly crispy.

Step 7: Serve and Enjoy!

Let the onions cool for a few minutes before serving. Garnish with fresh herbs for a pop of color and freshness.
