Ingredients You’ll Need
These ingredients are deceptively simple but each plays a crucial role in building the layers of flavor and luscious texture that make this dish sing. From the sweet onions providing a tender base to the trio of cheeses adding richness and depth, every component is essential.
- 3-4 large sweet onions (Vidalia or similar): Their natural sweetness and mild flavor make them ideal for baking and pairing beautifully with cheese.
- 2 tablespoons butter, cut into small pieces: Adds richness and helps the onions caramelize slightly in the oven.
- Salt and pepper, to taste: Essential for enhancing the natural onion flavors and seasoning the dish perfectly.
- 1 teaspoon garlic powder: Brings a subtle garlicky warmth without overpowering sweetness.
- 1 teaspoon dried or fresh thyme: Adds an earthy herbal note that pairs wonderfully with baked onions.
- 1 cup shredded mozzarella: Offers gooey meltiness and mild creaminess.
- 1 cup shredded Gruyère or Swiss cheese: Brings nutty, slightly sweet complexity and perfect browning capability.
- 1/4 cup heavy cream (optional): Creates a silky texture and helps the cheeses meld beautifully with the onions.
- 1/3 cup grated Parmesan cheese: A sharp, salty finish sprinkled on top before serving for extra flavor and a hint of crisp.
How to Make Cheesy Baked Tennessee Onions Recipe
Step 1: Prepare Your Oven and Onions
Start by preheating your oven to 375°F (190°C), ensuring it’s hot and ready to bake those onions to tender, cheesy perfection. Peel your onions carefully, then slice each into half-inch thick rings, which will hold their shape while baking and provide that satisfying texture.
Step 2: Arrange and Season the Onion Rings
Use a buttered cast iron skillet or a sturdy baking dish to arrange your onion slices, slightly overlapping them for a beautiful layered effect. Season generously with salt, pepper, garlic powder, and thyme, which all work together to lift the flavors of the sweet onions and cheese.
Step 3: Add Butter and Cheese
Scatter the small butter pieces across the onion layers—this will melt down and enhance every bite with luxurious richness. Then, sprinkle a generous layer of mozzarella and Gruyère or Swiss cheese over the top, distributing them evenly for a wonderfully gooey, melty finish. If you’re using heavy cream, drizzle it over now for extra silkiness.
Step 4: Bake Until Golden and Bubbly
Place your skillet or baking dish into the preheated oven uncovered. Bake for 25 to 30 minutes until the onions become tender and the cheeses turn golden and bubbly, signaling it’s ready to come out of the oven. The melting cheese and softened onions create an irresistible aroma.
Step 5: Finish with Parmesan and Rest
As soon as you remove the dish from the oven, sprinkle the grated Parmesan evenly over the top. Let it rest for about 5 minutes—this allows the cheese to set slightly and the flavors to marry perfectly before serving up your amazing Cheesy Baked Tennessee Onions Recipe.

Garnishes

Make Ahead and Storage
Storing Leftovers

Freezing
This dish freezes pretty well. To freeze, cool completely and transfer to a freezer-safe airtight container. Freeze for up to 2 months. When ready, thaw overnight in the fridge before reheating to preserve texture and taste.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) for about 10-15 minutes until warmed through and bubbly again. Avoid microwaving if possible, as it can make the onions soggy and cheese less appealing.
FAQs
Can I use other types of onions for this recipe?
While Vidalia or sweet onions are preferred for their natural sweetness and mild flavor, you can experiment with yellow onions. Just keep in mind the flavor will be a bit more pungent, which might alter the dish’s signature sweetness.
Is this recipe suitable for vegetarians?
Absolutely! This recipe contains no meat and is perfect for vegetarians who enjoy rich, cheesy comfort food. Just make sure to check your cheese labels if you follow strict vegetarian guidelines.
Can I substitute the cheeses in this dish?
You can swap Gruyère or Swiss cheese for similar melting cheeses like fontina or provolone for a slightly different but still delicious flavor profile. However, avoid very strong-flavored cheeses which might overpower the onions.
What can I do if I don’t have heavy cream?
The heavy cream is optional and primarily adds silkiness. You can omit it or substitute with whole milk or half-and-half, though the texture may be a bit lighter but still tasty.
How do I make sure the onions cook evenly?
Cutting the onions into uniform half-inch rings helps them cook at the same rate. Also, arranging them slightly overlapping but in a single layer ensures even heat distribution during baking.
