How to Make Tennessee Onions
-
Preheat the oven: Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish to ensure those Tennessee Onions don’t stick during baking.
-
Layer the onions: Slice your sweet onions into thick rings and layer them in the dish, making sure to keep the rings separate. This helps them cook evenly and achieve that perfect tenderness!
-
Season with butter and spices: Drizzle the melted unsalted butter over the onions, followed by an even sprinkle of garlic powder, dried thyme, salt, and black pepper. Stir gently to coat the rings well with flavors.
-
Add the cheese: Evenly distribute the shredded cheddar, Monterey Jack, and grated Parmesan cheeses on top of the seasoned onions, making sure every bite is loaded with cheesy goodness.
-
Bake covered: Cover the dish with foil and bake for 25 minutes. This will allow the onions to soften beautifully while keeping the cheese from burning.
-
Finish baking uncovered: Remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden brown. A lovely crust is what you’re looking for!
-
Cool before serving: Allow the Tennessee Onions to cool slightly before serving. This will help the flavors meld and make it easier to scoop out those cheesy layers.

Tennessee Onions Recipe FAQs
What type of onions should I use for Tennessee Onions?
I absolutely recommend using sweet onions, such as Vidalia, for the best flavor experience! They provide a lovely natural sweetness that complements the rich cheese. If sweet onions are unavailable, yellow onions can be a suitable substitute, although the flavor will be slightly different.
How should I store leftover Tennessee Onions?
To keep your delicious Tennessee Onions fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure they are cool before sealing the container, as this helps preserve their flavor and texture.
Can I freeze Tennessee Onions?
Yes, you can! Freeze the baked Tennessee Onions by wrapping them tightly in plastic wrap, then in aluminum foil. They can last up to 3 months in the freezer. When you’re ready to enjoy them, thaw in the fridge overnight and reheat in a preheated oven at 350°F (175°C) for 15-20 minutes until heated through and the cheese is bubbly again.
What should I do if my cheese is burning while baking?
If you notice the cheese starting to burn, don’t worry! The best solution is to cover the dish with foil during the initial baking period. This will protect the cheese while the onions soften. After about 25 minutes, remove the foil to allow the cheese to brown beautifully for the last 10 minutes.
Are Tennessee Onions safe for my pet?
It’s important to remember that onions can be toxic to dogs and cats, so please avoid sharing Tennessee Onions with your furry friends! If you have pets, find alternatives that are pet-friendly.
Can I use fresh garlic instead of garlic powder?
Certainly! If you prefer a more robust garlic flavor, you can use fresh minced garlic instead of garlic powder. Just remember, a little goes a long way! I suggest using about 2-3 cloves, finely minced, to replace the garlic powder in the recipe to avoid overpowering the dish.
