Preparing the Onions for Your Tennessee Onions

1. Peel and Slice the Onions: First things first, let’s tackle those beautiful onions. Carefully peel away the outer skin from each of your six large yellow onions. For the best texture in your Tennessee Onions, you’ll want to slice them thinly and uniformly. I like to cut them into about ¹/₈-inch thick rings or half-moons if they’re particularly large. A sharp knife is your best friend here, or if you have a mandoline, it will make this task incredibly easy and ensure consistency. Just be careful with your fingers! You’ll end up with a very generous pile of sliced onions, but don’t worry, they will cook down considerably.
2. Sauté the Onions in Batches: This step is crucial for developing the foundational flavor of our Tennessee Onions, setting them apart as The Cheesy Baked Side Dish Better Than Onion Rings. In a large, heavy-bottomed pot or Dutch oven, melt 1 tablespoon of unsalted butter with ¹/₂ tablespoon of olive oil over medium heat. Once the butter is melted and shimmering, add about half of your sliced onions. Sprinkle them with ¹/₄ teaspoon of salt and ¹/₈ teaspoon of black pepper.
3. Softening and Sweetening: Sauté these onions, stirring frequently, until they are very soft, translucent, and just beginning to turn golden. This process isn’t about caramelizing them deeply, but rather about sweating them down to release their natural sweetness and soften their texture. This typically takes about 15-20 minutes per batch. You want them tender, but not mushy. Once the first batch is done, transfer them to a large bowl and set aside.
4. Repeat with Remaining Onions: Add the remaining 1 tablespoon of unsalted butter and ¹/₂ tablespoon of olive oil to the same pot. Add the rest of your sliced onions, along with the remaining ¹/₄ teaspoon of salt and ¹/₈ teaspoon of black pepper. Continue to cook this second batch in the same manner until they are beautifully soft and tender. Once cooked, add them to the bowl with the first batch. Set these softened onions aside while we prepare our luxurious cheesy sauce.

Crafting the Creamy Cheesy Sauce for Tennessee Onions

5. Prepare Your Roux: In the same large pot or Dutch oven (no need to clean it if there are any delicious onion bits sticking to the bottom, those are flavor!), melt 6 tablespoons of unsalted butter over medium heat. Once the butter is fully melted and foamy, sprinkle in the ¹/₂ cup of all-purpose flour. Whisk continuously for 2-3 minutes to create a smooth, pale roux. You’ll want to cook out the raw flour taste, so keep whisking until it smells a bit like popcorn and looks lightly golden. This roux is what will thicken our incredible cheesy sauce, making our Tennessee Onions so wonderfully rich.
6. Whisk in the Milk: Gradually, and I mean gradually, whisk in the 3 cups of warm whole milk. Adding warm milk helps prevent lumps, but don’t fret if a few appear; persistent whisking will smooth them out. Pour in a small amount of milk, whisk until it’s fully incorporated and the mixture is thick, then add a bit more, continuing this process until all the milk has been added and you have a smooth, creamy sauce. Keep whisking and bring the sauce to a gentle simmer. It will thicken considerably as it heats.
7. Season the Sauce: Once your sauce is thick and smooth, reduce the heat to low. Now it’s time to add the flavor powerhouses! Stir in the 1 teaspoon of dry mustard powder, ¹/₂ teaspoon of garlic powder, and the optional ¹/₄ teaspoon of cayenne pepper. The dry mustard doesn’t make the sauce taste like mustard; instead, it enhances the savory notes of the cheese, making it taste even cheesier! Add 1 teaspoon of salt and ¹/₂ teaspoon of black pepper. Stir well to combine all the seasonings.
8. Melt in the Cheeses: This is where the magic happens and our Tennessee Onions earn their “cheesy” moniker. Remove the pot from the heat. Add 3 cups of your shredded sharp cheddar cheese and all of the 1 cup of shredded Gruyère cheese (or Monterey Jack). Stir gently until the cheeses are completely melted and incorporated, creating a velvety, luxurious cheese sauce. Taste and adjust seasoning if needed. You might want a little more salt or pepper, depending on your preference and the saltiness of your cheese. Make sure the sauce is perfectly seasoned and wonderfully smooth. This rich, creamy sauce is going to coat our tender onions beautifully, creating a side dish that truly rivals (and in my opinion, surpasses) traditional onion rings.

Assembling Your Tennessee Onions

9. Combine Onions and Sauce: Gently fold the softened onions into the prepared cheesy sauce. Ensure every tender strand of onion is generously coated with that delicious, creamy goodness. You want an even distribution of the onions throughout the sauce. This mixture is the heart of our Tennessee Onions The Cheesy Baked Side Dish Better Than Onion Rings.
10. Prepare Your Baking Dish: Lightly grease a 9×13-inch baking dish. You can use a bit of butter or a non-stick cooking spray. This prevents the edges of your glorious cheesy onion dish from sticking.
11. Transfer to Baking Dish: Pour the entire onion and cheese mixture into your prepared baking dish. Spread it out evenly with a spatula to ensure a consistent thickness. You want every spoonful to be a perfect balance of onions and that incredible cheesy sauce.
12. Add the Topping: If you’re using panko breadcrumbs for that extra delightful crunch (which I highly recommend!), combine the ¹/₂ cup of panko breadcrumbs with 2 tablespoons of melted unsalted butter in a small bowl. Stir until the breadcrumbs are evenly coated. Now, sprinkle the remaining 1 cup of shredded sharp cheddar cheese evenly over the top of the onion mixture. If using, follow this with an even layer of the buttered panko breadcrumbs. This topping isn’t just for looks; it creates a fantastic golden crust that adds wonderful textural contrast to the soft, creamy interior of the Tennessee Onions, making it truly standout as a cheesy baked side dish.

Baking The Cheesy Goodness of Tennessee Onions

13. Preheat Your Oven: Preheat your oven to 375°F (190°C). This allows the oven to reach a consistent temperature, ensuring even baking.
14. Bake Until Bubbly and Golden: Place the baking dish into the preheated oven. Bake for 30-35 minutes, or until the Tennessee Onions are hot and bubbly around the edges, and the cheese topping is melted and golden brown. If you used breadcrumbs, they should be beautifully toasted and crisp. Keep an eye on it during the last 10 minutes to prevent the topping from over-browning. If it starts to get too dark, you can loosely tent the dish with aluminum foil. This baking process transforms simple ingredients into something truly extraordinary, a rich and comforting side dish that’s far more substantial and satisfying than any fried onion ring.
15. Achieving Perfection: What we’re looking for here is that perfect balance: an interior that’s creamy, tender, and intensely flavorful, with a top layer that offers a delightful textural crunch and a burst of concentrated cheesy goodness. The aroma filling your kitchen will be absolutely divine, a testament to the fact that these are indeed Tennessee Onions The Cheesy Baked Side Dish Better Than Onion Rings.

Serving Your Delicious Tennessee Onions

16. Rest Before Serving: Once your Tennessee Onions come out of the oven, it’s tempting to dive right in! However, for the best results, allow the dish to rest for about 5-10 minutes. This resting period allows the cheese sauce to set slightly, making it easier to serve and ensuring that each spoonful holds its shape beautifully. It also prevents those immediate, super-hot cheese burns on your tongue!
17. Garnish and Serve: If desired, sprinkle with fresh chopped parsley or chives for a touch of color and freshness. A light dusting of paprika can also add visual appeal. Serve your Tennessee Onions warm as a spectacular side dish alongside roasted meats, poultry, or any comfort food meal. It’s incredibly versatile and pairs wonderfully with so many main courses.
18. The Ultimate Side Dish: You’ll quickly discover why this dish is often called Tennessee Onions The Cheesy Baked Side Dish Better Than Onion Rings. Unlike fried onion rings, which can be greasy and heavy, these baked onions offer a depth of flavor, a creamy texture, and a comforting warmth that makes them truly special. The combination of sweet, tender onions enveloped in a rich, savory, and incredibly cheesy sauce, all baked to golden perfection, is simply irresistible.

A blend of Gruyere and sharp white cheddar would also be phenomenal, adding a gourmet touch. Want to introduce more texture or flavor? Consider adding some crumbled, crispy bacon bits to the topping mixture, or even a handful of finely chopped fresh chives or parsley for a burst of herbaceous freshness. For a touch of heat, a few finely diced jalapeños (seeds removed for less spice) mixed into the onion layer before baking would be divine. If you’re catering to dietary restrictions, feel free to use gluten-free crackers for the topping, ensuring the same satisfying crunch, and always double-check that your cheese is made with vegetarian rennet if needed.
