Step‑by‑Step Instructions for Tennessee Onions
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms, lightly butter a casserole dish or a 9×13-inch pan to prevent the onions from sticking. This crucial step sets the stage for achieving that melt-in-your-mouth texture that defines Tennessee Onions.
Step 2: Prepare the Onions
Peel the sweet onions, such as Vidalia or yellow, and slice them into thick, ½ inch rings. Arrange these rings flat in the buttered baking dish, allowing their natural sweetness to shine through. The visual of the stacked onion rings should invite you to dig in as they get ready for the oven.
Step 3: Season the Onions
Now it’s time to enhance your sweet onions! Generously sprinkle salt, pepper, and Italian seasoning over the sliced onions, ensuring even distribution for maximum flavor. Dot the onion rings with small pats of butter, giving them a rich and savory base to absorb as they bake.
Step 4: Layer the Cheese
Next, add a layer of shredded mozzarella cheese atop the seasoned onions. Follow with slices of provolone for an added depth of creaminess. Finally, sprinkle grated Parmesan cheese generously on top for a golden, crispy finish. This delightful cheese trio will make your Tennessee Onions irresistibly cheesy.
Step 5: Bake the Dish
Carefully place the assembled dish in the preheated oven, baking uncovered for 25-30 minutes. Keep an eye on it; you’ll know it’s ready when the cheese is bubbling and becomes a beautiful golden color. If you’re craving an extra crispy topping, you can broil for 2 minutes towards the end—just watch closely!
Step 6: Rest & Serve
Once the cheese is perfectly melted and golden, remove the dish from the oven and allow it to rest for about 5 minutes. This resting period helps the cheese set slightly for easier serving. Now, scoop out the delectable Tennessee Onions and enjoy the cheesy, caramelized layers that await you!

Storage Tips for Tennessee Onions
Fridge: Store leftovers in an airtight container for up to 3 days. This ensures that the cheesy goodness remains fresh and ready to reheat.
Freezer: Tennessee Onions can be frozen for up to 2 months. Use a freezer-safe container, separating layers with parchment paper to avoid sticking.
Reheating: To maintain the cheesy texture, reheat in the oven at 350°F for about 10 minutes. Avoid microwaving to prevent the cheese from becoming rubbery.
Serving Suggestions: Enjoy reheated Tennessee Onions as a delightful side dish alongside your favorite grilled meats or vegetarian meals for a satisfying experience.

You can slice and season the sweet onions up to 24 hours in advance, layering them with salt, pepper, and Italian seasoning to enhance their flavor. After preparing, cover the dish tightly and refrigerate overnight to maintain freshness. When it’s time to serve, simply sprinkle your cheese layers and bake as directed. Just remember, for the best quality, avoid adding the cheese until you’re ready to bake, as this keeps the cheese fresh and melty.

Tennessee Onions Recipe FAQs
How do I choose the right onions for this recipe?
Absolutely! Select sweet onions, like Vidalia or yellow onions, which are known for their natural sweetness and mild flavor. Look for onions that feel firm, without soft spots, and avoid any with dark spots or blemishes. Slicing them into ½ inch thick rings allows for optimal baking, ensuring they become tender and flavorful.
What is the best way to store leftovers of Tennessee Onions?
Very! Store any leftovers in an airtight container in the refrigerator for up to 3 days. This keeps the cheesy goodness fresh. When you’re ready to enjoy them again, reheat in the oven at 350°F (175°C) for about 10 minutes to restore that lovely crispy texture. Avoid using the microwave; it can cause the cheese to become rubbery.
Can you freeze Tennessee Onions? If so, how?
Certainly! To freeze Tennessee Onions, first, cool them completely after baking. Then, transfer the leftover onions to a freezer-safe container. I recommend using parchment paper between layers to prevent them from sticking together. They can last up to 2 months in the freezer. When you’re ready to eat, thaw in the refrigerator overnight and reheat in the oven.
What if my cheese doesn’t melt properly?
No worries! If your cheese doesn’t melt well, it might be due to the type of cheese used—for a truly stretchy melt, always opt for mozzarella and ensure it’s evenly distributed. Ensure the baking time is sufficient (25-30 minutes) and consider adding a quick broil at the end for 1-2 minutes to achieve that perfect golden and bubbly top, but stay close to prevent burning.
Are Tennessee Onions safe for my dog?
Great question! No, unfortunately, onions can be harmful to dogs as they can lead to health issues like anemia. If you’re sharing a meal, it’s best to keep these cheesy delights off their plate. If you need pet-friendly alternatives, consider making a similar dish with cooked sweet potatoes and cheese, which are safe and enjoyable for them.
Can I use different types of cheese?
Absolutely! Feel free to experiment with cheese variations. While the classic blend features mozzarella, provolone, and Parmesan, you can swap mozzarella for sharp cheddar, Monterey Jack, or Gruyère for a different flavor profile. If you love a bit of heat, consider using pepper jack cheese or adding red pepper flakes for a spicy kick!
