- Sweet onions: The star of the dish, their natural sweetness softens beautifully when baked, creating a tender, flavorful base.
- Garlic powder: Adds a subtle punch of savory depth without overpowering the onions.
- Italian seasoning: A fragrant mix of herbs that elevates the overall flavor profile with a hint of warmth and earthiness.
- Salt: Enhances all the flavors and balances the sweetness of the onions perfectly.
- Ground black pepper: Brings a mild heat that cuts through the richness of the cheeses.
- Unsalted butter: Slices melt over the onions, adding richness and helping the seasoning adhere beautifully.
- Shredded cheddar cheese: Offers sharp, tangy notes that pair wonderfully with the sweet onions.

- Grated parmesan cheese: Sprinkled on top for a nutty, salty finish that crisps up delightfully in the oven.
How to Make Tennessee Onions Recipe
Step 1: Preheat the Oven
Begin by setting your oven to 350°F (175°C) so it reaches the perfect temperature for baking. This steady heat allows the cheese to melt evenly and the onions to cook until tender without drying out.
Step 2: Prepare Onions
Peel the sweet onions and slice them into even rings. Carefully separate these rings and arrange them evenly in a greased 9 x 13-inch baking dish. This arrangement ensures each onion layer gets plenty of exposure to the flavors and cheese.
Step 3: Season the Onions
Sprinkle the garlic powder, Italian seasoning, salt, and ground black pepper evenly over the onion rings. This seasoning blend infuses a wonderful aroma and deep savory notes that complement the natural sweetness of the onions.
Step 4: Add Butter
Slice the unsalted butter and distribute the pieces across the top of the seasoned onions. As the dish bakes, the butter will melt into the layers, enriching them and helping everything meld together beautifully.
Step 5: Add Cheeses
Layer the shredded cheddar, Italian blend cheese, and grated parmesan evenly on top of the onions and butter. The mixture of cheeses melts into a gooey, golden crust that creates the dish’s trademark decadent texture and flavor.
Step 6: Bake Until Golden and Melty
Place the baking dish in the preheated oven and bake for 25 to 30 minutes. Watch as the cheese melts into bubbling, golden perfection while the onions soften to a tender, irresistible softness.
How to Serve Tennessee Onions Recipe
Garnishes
Fresh herbs like chopped parsley or chives add a pop of color and a bright, fresh flavor that contrasts perfectly with the rich cheeses. A light dusting of extra parmesan or a few cracked black peppercorns sprinkled on top before serving also makes for a beautiful presentation.
Side Dishes
This Tennessee Onions Recipe pairs wonderfully with hearty main courses like grilled steak, roasted chicken, or even a juicy pork chop. It’s equally tasty alongside a fresh green salad or roasted vegetables, balancing creamy indulgence with lighter, crisp textures.
Creative Ways to Present
For a casual family style meal, serve the onions straight in the baking dish, allowing everyone to scoop out their portions. If you want to impress guests, try serving the onions in individual ramekins or as a decadent layer atop baked potatoes for a gourmet twist.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers into an airtight container and keep them in the refrigerator. The Tennessee Onions Recipe stays delicious for up to 3 days, making it great for a make-ahead side dish or next-day indulgence.
Freezing
If you want to freeze this dish, it’s best to do so before baking. Cover the prepared onions tightly with plastic wrap and foil, then freeze for up to a month. Bake directly from frozen, adding about 10 extra minutes to the baking time to ensure it’s heated through.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and the cheese regains its melty, bubbly texture. Avoid microwaving if possible, as the texture of the onions may become watery and less appealing.
FAQs
Can I use other types of onions for this Tennessee Onions Recipe?
While sweet onions are preferred for their natural sweetness and softer texture, yellow or Vidalia onions can also work well. Just keep in mind the flavor profile may shift slightly, becoming sharper or less sweet.
Is it possible to make this recipe dairy-free or vegan?
You can substitute the butter with vegan butter and use dairy-free cheeses that melt well. However, the flavor and texture will differ from the original recipe, but it can still be a delicious alternative!
How can I make this recipe spicier?
Adding a pinch of crushed red pepper flakes over the onions before baking or incorporating a dash of cayenne pepper into the seasoning mix adds a gentle but welcome spark of heat.
Can this dish be made ahead and baked later?
Yes! You can prepare the onions with seasoning, butter, and cheese, then cover and refrigerate for up to 24 hours before baking. This makes it great for entertaining and busy days.
What’s the best way to slice the onions for even cooking?
Use a sharp knife to cut the onions into evenly thick rings, about 1/4 inch thick. This helps ensure that all the layers cook uniformly and maintain their texture under the cheese topping.
