How to Make Tennessee Onions
-
Preheat the Oven: Start by preheating your oven to 375°F (190°C). This ensures even cooking, leaving the cheese perfectly melted and bubbly.
-
Prepare the Baking Dish: Lightly grease a 9×13-inch baking dish with cooking spray or a bit of butter. This will help the onions not stick and make serving easier.

Season the Onions: Drizzle the melted butter evenly over the onions. Then, sprinkle them with garlic powder, dried thyme, salt, and black pepper for a delicious flavor boost.
-
Add the Cheese: Generously top the seasoned onions with the cheddar, Monterey Jack, and Parmesan cheeses. Make sure to cover them completely for that yummy cheesy crust we all crave!

Bake to Perfection: Cover the baking dish with foil and bake in the preheated oven for 25 minutes. After that, remove the foil and bake for an additional 10 minutes or until the cheese is golden and bubbly.

Evenly Space Onions: Ensure the onion rings are spaced apart in the baking dish. This promotes even cooking and a perfectly cheesy crust.

Use Finely Shredded Cheese: For the best melting results, opt for finely shredded cheddar, Monterey Jack, and Parmesan. This helps avoid clumping and enhances the creaminess.
-
Cover with Foil: When first baking, cover the dish with foil. This traps steam and creates a tender texture, ensuring the onions cook while allowing the cheese to melt perfectly.

Adjust Seasoning To Taste: Always taste the seasonings before baking. If you prefer more heat, add extra black pepper or even a pinch of cayenne to your Tennessee Onions.

Tennessee Onions Recipe FAQs
What type of onions should I use for Tennessee Onions?
I recommend using sweet onions for their natural sweetness and flavor. They provide the perfect base for this dish. If you can’t find sweet onions, yellow onions work just as well.
How should I store leftover Tennessee Onions?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. This will help keep the cheese from drying out while keeping the flavors intact. When you’re ready to enjoy them again, simply reheat in the oven or microwave.
Can I freeze Tennessee Onions?
Absolutely! To freeze, allow the Tennessee Onions to cool completely. Then wrap them tightly in plastic wrap followed by aluminum foil, ensuring no air gets in. They can be frozen for up to 2 months. When you’re ready to eat, thaw them in the fridge overnight and reheat in the oven at 350°F (175°C) for 15-20 minutes until heated through.
What if my cheese doesn’t melt properly?
If your cheese isn’t melting as desired, make sure you are using finely shredded cheese, as it melts more efficiently than block cheese. Additionally, covering the dish with foil during the initial baking helps create steam, aiding in that luscious melt. If you notice clumping, gently toss the cheese before adding it to the onions for better distribution.
Are Tennessee Onions suitable for people with dairy allergies?
Unfortunately, this dish contains multiple types of cheese, making it unsuitable for those with dairy allergies. However, you can make variations using dairy-free cheese alternatives, such as a plant-based cheddar or mozzarella. You might need to adjust baking times as these cheeses can have different melting properties.
How long can I prepare Tennessee Onions ahead of time?
These can be assembled a day ahead and stored in the fridge before baking. Just cover the baking dish tightly with foil to keep it fresh. When you’re ready to cook, preheat the oven and bake according to the original instructions, adding a few extra minutes if they are coming straight from the refrigerator.
