- Salt (1/2 teaspoon): Balances and enhances the natural sweetness of the onions.

How to Make Tennessee Onions Recipe
Step 1: Prep the Pan and Onions
Start by preheating your oven to 350°F (175°C) and generously spraying a 9×13-inch baking dish with non-stick spray. As the oven warms, peel your onions and carefully slice them into thin rounds—about 1/4 inch thick is perfect. Gently separate the rounds into individual rings, like a blooming floral garland, and scatter them evenly in the baking dish.
Step 2: Season the Onions
Sprinkle the onions with garlic powder, Italian seasoning, salt, and black pepper. Give them a loving toss or use your fingers to ensure each ring gets kissed by the seasonings. This builds a flavorful base for the cheeses to melt into.
Step 3: Add Butter and Cheese Layers
Dot the seasoned onions with thin slices of butter, distributing evenly for rich, savory flavor in every bite. Layer on the shredded cheddar first, followed by the Italian blend or mozzarella, then finish with a generous shower of grated parmesan for that irresistible golden top.
Step 4: Bake to Golden Perfection
Slide the dish into your preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the cheese is fully melted, bubbly, and you catch a glimpse of golden, caramelized edges. Let your Tennessee Onions Recipe cool for just a minute, then serve piping hot for the ultimate cheesy, comforting side.
Pro Tips for Making Tennessee Onions Recipe
- Onion Selection Matters: Choose the sweetest onions you can find (Vidalia is king!)—their natural sugars caramelize beautifully and balance the cheeses perfectly.
- Mind the Cheese Layering: For the best ooey-gooey stretch, layer cheddar first, then Italian blend, and always finish with parmesan on top for the signature crispy crust.
- Slice Evenly: Uniform onion rings ensure every bite cooks evenly for the perfect tender-yet-textured result.
- Butter Distribution: Dot butter all over instead of piling it in one spot—this helps every edge brown up and adds amazing flavor throughout the dish.
How to Serve Tennessee Onions Recipe
Garnishes
Top your Tennessee Onions Recipe with a sprinkle of fresh parsley or chopped chives right before serving for a pop of color and freshness. If you love a little tang, a dollop of sour cream on the side takes things to the next level!
Side Dishes
This cheesy onion bake pairs beautifully with classic Southern mains: try it alongside grilled steak, BBQ chicken, or pork chops. It’s also a surprising hit next to roasted vegetables, fresh salads, or even as part of a holiday spread with turkey or ham.
Creative Ways to Present
Serve the Tennessee Onions Recipe straight from the baking dish for ultimate comfort-food vibes, or scoop individual portions into mini ramekins for an elegant touch at dinner parties. Try tucking leftovers into sandwiches or spooning over baked potatoes for an extra-cozy treat!
Make Ahead and Storage
Storing Leftovers
If you somehow end up with leftovers (good luck!), cover and refrigerate them in an airtight container for up to 3 days. This dish actually gets even more delicious as the flavors meld together overnight.
Freezing
You can freeze the Tennessee Onions Recipe before baking (just assemble and cover tightly) for up to one month. Thaw overnight in the fridge, then bake as directed. Fully baked leftovers aren’t the best candidate for freezing, since cheese can become a tad grainy when reheated.
Reheating
Warm leftovers in a 325°F oven for about 15 minutes, or until the cheese is bubbly again. For single servings, the microwave works in a pinch—just cover loosely and heat in 30-second bursts—though oven reheating keeps that top perfectly crisp.
FAQs
-
Can I use regular yellow onions instead of sweet onions?
Yes, you can use yellow onions in a pinch—the results will still be delicious! However, sweet onions (like Vidalia) give the Tennessee Onions Recipe its signature mild, caramelized flavor. If you do substitute, consider tossing the onions in a pinch of sugar before baking to mimic that natural sweetness.
-
Is this dish vegetarian?
This recipe is vegetarian as written, using only butter and cheeses for richness. Just double-check your cheese labels for any animal rennet if you serve strict vegetarians.
-
Can I prepare Tennessee Onions Recipe ahead of time?
Absolutely! Assemble everything in the baking dish, cover tightly, and refrigerate for up to 24 hours before baking. Wait to add the parmesan until right before baking if you want the crispy golden crust to be at its best.
-
What can I do if my cheese is browning too quickly?
If you notice the top is browning too fast before the onions are tender, gently tent the dish with foil during the last 10 minutes of baking. This allows everything to cook evenly while keeping that cheesy goodness golden, not burnt.
Final Thoughts
If you love melty, cheesy comfort food and a Southern twist, this Tennessee Onions Recipe absolutely needs to be on your table. Give it a whirl for your next gathering or family dinner—you’ll be amazed at how quickly it disappears and how many requests you’ll get for the recipe. Dig in and enjoy every gooey, golden bite!
