How to Make Tennessee Onions
-
Preheat the oven to 375°F (190°C). Start by lightly buttering a 9×13-inch casserole dish to ensure a beautiful crust forms on the onions during baking.
-
Slice the sweet onions into ½ inch thick rings. Lay them flat in the prepared dish, making sure each slice is positioned nicely to absorb all the flavors.
-
Season the onion layers with salt, pepper, and Italian seasoning. This step is crucial for adding those warm, comforting flavors that make this dish a hit!
-
Distribute small pats of butter evenly over the onion slices. This will help caramelize the onions and lend a rich flavor as they bake.
-
Layer with shredded mozzarella cheese, followed by slices of provolone cheese, finishing with a generous sprinkle of grated Parmesan on top. This combination ensures a gooey and crispy finish!
-
Bake uncovered for 25-30 minutes. You’re looking for bubbling cheese and a golden color on top. If you want extra crispiness, broil for an additional 2 minutes.

Rest the dish for 5 minutes before serving. This allows the cheesy goodness to settle, enhancing the flavors even more!
Optional: Garnish with fresh herbs for added freshness.

Tennessee Onions Recipe FAQs
What type of onions should I use for Tennessee Onions?
I recommend using sweet onions, like Vidalia or yellow onions, for their natural sweetness and rich flavor. If you can’t find them, white onions can be a suitable substitute; just avoid red onions, as they tend to lose both color and flavor when baked.
How should I store leftover Tennessee Onions, and how long will they last?
Store your leftover Tennessee Onions in an airtight container in the refrigerator for up to 3 days. This method keeps them fresh and ready for a quick reheat when you’re craving that cheesy goodness again!
Can I freeze Tennessee Onions? If so, how?
Absolutely! To freeze your Tennessee Onions, first let the dish cool completely. Then, wrap it tightly in plastic wrap and follow with aluminum foil to prevent freezer burn. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy, thaw overnight in the refrigerator and reheat in the oven at 350°F for about 10-15 minutes until warmed through.
What can I do if my cheese doesn’t melt properly?
If your cheese isn’t melting well, it might mean it’s too cold when added to the dish or that it was overcooked. Make sure to use freshly shredded cheese rather than pre-shredded, as it often contains anti-caking agents that can affect melting. Also, ensure your oven is fully preheated before baking!
Are Tennessee Onions safe for people with food allergies?
This recipe is vegetarian-friendly, but be cautious if anyone has cheese allergies or lactose intolerances. As a modification, you can use dairy-free cheese alternatives for a delicious, allergen-friendly version. Always check ingredient labels for hidden allergens, especially if you’re serving guests with dietary concerns.
Can I make Tennessee Onions in advance?
Yes! You can prepare the dish ahead of time by assembling it without baking. Just cover it tightly and keep it in the refrigerator until you’re ready to bake. When baking, you may need to increase the time slightly since it will start from a colder temperature. This way, you can enjoy that cheesy goodness without any last-minute hassle!
