- Italian seasoning (1/2 teaspoon): Brings an herby note that lifts the overall flavor profile.
- Salt (1/2 teaspoon): Essential to enhance the innate sweetness in the onions.
- Ground black pepper (1/4 teaspoon): Provides a gentle warmth and depth.
- Unsalted butter (4 tablespoons): Richness that helps the cheese melt beautifully and coats the onions in flavor.
- Shredded cheddar cheese (2 cups): Sharp and tangy, cheddar adds that classic cheesy punch.

How to Make Tennessee Onions Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350°F (175°C) and greasing a 9 x 13-inch baking dish. This simple prep step ensures your Tennessee Onions Recipe bakes evenly without sticking, making clean-up much easier later on.
Step 2: Slice and Arrange the Onions
Peel your sweet onions and carefully slice them into rings. Separating these rings layer by layer in the baking dish sets a beautiful, rustic foundation that will cook down to tender, melt-in-your-mouth bites.
Step 3: Season the Layers
Sprinkle garlic powder, Italian seasoning, salt, and pepper evenly over the onions. This seasoning mix is the secret heart of the Tennessee Onions Recipe, infusing the dish with subtle layers of flavor that tease your palate with every forkful.
Step 4: Add the Butter
Dot the top of the seasoned onions with slices of unsalted butter. As the dish bakes, the butter will melt and mingle with the cheese and onions, creating a rich, silky texture that makes this side absolutely irresistible.
Step 5: Layer on the Cheeses
Generously sprinkle the shredded cheddar, Italian blend, and Parmesan cheeses over the buttered onions. The combination of sharp, creamy, and nutty cheeses is what gives your Tennessee Onions Recipe that signature bubbly, golden crust that’s hard to resist.
Step 6: Bake to Perfection
Pop the dish into your preheated oven and bake for 25 to 30 minutes, or until the cheeses have fully melted and turned a gorgeous golden brown. The oven’s warmth draws out the natural sweetness of the onions while melding the flavors into a harmonious whole.
Step 7: Serve Warm and Enjoy
This dish is best enjoyed hot from the oven when the cheese is still silky and smooth. Scoop generous portions onto your plate and savor the rich, cheesy, comforting goodness of this classic Tennessee Onions Recipe.

Absolutely! While sweet onions provide the best balance of flavor and sweetness, yellow or Vidalia onions can be used and will still give you a delicious result.

Yes! Assemble the dish, cover it tightly, and refrigerate for up to 24 hours before baking as directed. This makes it easy to prepare for gatherings or busy weeknights.
What’s the best way to slice the onions for this recipe?
Using a sharp knife or mandoline, slice the onions into even rings about 1/4 inch thick to ensure even cooking and perfect layering in the baking dish.
