Ingredients
- 3 large sweet onions (such as Vidalia or Walla Walla), about 900 grams (2 pounds)
- 113 grams (1/2 cup) unsalted butter, cut into small cubes
- 5 grams (1 teaspoon) fine sea salt
- 3 grams (1 teaspoon) garlic powder
- 2 grams (1 teaspoon) dried oregano
- 3 grams (1 teaspoon) smoked paprika
- 0.5 grams (1/4 teaspoon) cayenne pepper (optional, for a subtle warmth)
- 113 grams (1 cup) shredded mozzarella cheese
- 113 grams (1 cup) shredded sharp cheddar cheese
- 56 grams (1/2 cup) grated Parmesan cheese
Instructions
- Preheat your oven to 190°C (375°F) and prepare a 9×13-inch (23×33 cm) baking dish. Lightly grease the inside of the dish with butter or a non-stick cooking spray to prevent sticking and ensure easy serving.
- Carefully peel and slice the sweet onions into approximately 0.5 cm (1/4-inch) thick rounds. Arrange these sliced onions in a single, slightly overlapping layer within the prepared baking dish. This arrangement ensures even cooking and allows the flavors to meld beautifully. Evenly sprinkle the onions with the fine sea salt, garlic powder, dried oregano, smoked paprika, and the optional cayenne pepper, ensuring all surfaces are lightly coated for maximum flavor.
- Distribute the small cubes of unsalted butter over the seasoned onions. Dotting the butter in small pieces rather than larger chunks helps it melt evenly across the entire surface of the onions, contributing to their tenderness and rich flavor.
- Generously sprinkle the shredded mozzarella, shredded sharp cheddar, and grated Parmesan cheeses over the layered onions. Aim for an even distribution so that every bite offers a delightful cheesy coating.
- Place the dish in the preheated oven and bake for 30 to 35 minutes, or until the onions are perfectly tender when pierced with a fork and the cheese topping is thoroughly melted, bubbly, and a beautiful golden brown. For an intensified golden crust and slight crispiness, consider broiling the dish for an additional 1-2 minutes at the very end. Keep a close eye on it to prevent burning.
- Once baked to perfection, remove the Tennessee Onions from the oven. Allow them to cool for 5 minutes before serving. This brief cooling period helps the cheese set slightly, making it easier to serve without it running excessively. Serve warm as a delightful side dish, or as a rich topping for grilled burgers and savory sandwiches.
Tools You’ll Need
- 9×13-inch (23×33 cm) baking dish
- Sharp chef's knife
- Cutting board
- Measuring spoons and cups
- Cheese grater (if using blocks of cheese)
Essential Success Tips
- Always opt for sweet onions (like Vidalia, Walla Walla, or other sweet varieties) as they caramelize beautifully and provide the best flavor for this dish.
- Slice your onions to a consistent thickness (around 0.5 cm or 1/4-inch) to ensure they cook evenly and become uniformly tender.
- Avoid overcrowding the baking dish; if your onions are too thick, they may steam instead of tenderize and brown nicely. Use two dishes if necessary.
- For the ultimate melt and flavor, consider shredding your own cheese from blocks rather than using pre-shredded varieties, which often contain anti-caking agents.
- Don't skip the resting period after baking; it allows the cheese to set slightly, making the dish much easier and cleaner to serve.
Professional Cooking Secrets
- For an even deeper flavor profile, lightly sauté the sliced onions in a tablespoon of olive oil for 5-7 minutes until slightly softened before layering them in the baking dish. This pre-caramelization adds a layer of complexity.
- Infuse your butter before dotting: Gently melt the butter and stir in a pinch of fresh thyme or rosemary. Allow it to steep for a few minutes before pouring over the onions for an aromatic enhancement.
- Introduce a hint of acidity: A very light splash of white wine or vegetable broth (about 30-60 ml or 2-4 tablespoons) can be added to the bottom of the dish before baking to help keep the onions moist and add subtle depth as it simmers.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
- Variations: Feel free to experiment with different cheese blends! A smoky Gouda or a sharp Provolone could offer interesting twists. You can also add a sprinkle of crispy bacon bits or chopped fresh chives for an extra layer of flavor and garnish.
- Make Ahead: This dish can be assembled up to a day in advance and stored covered in the refrigerator. Allow it to come closer to room temperature for about 30 minutes before baking, and you might need to add an extra 5-10 minutes to the cooking time.
Frequently Asked Questions
Can I use red onions for this recipe?
While sweet onions are recommended for their mildness and ability to caramelize beautifully, you can certainly use red onions for a sharper, more piquant flavor profile. Keep in mind they might be slightly more intense than sweet onions.

Yes, Tennessee Onions are naturally gluten-free as all the ingredients used (onions, butter, spices, cheese) do not contain gluten. Always check ingredient labels to ensure no hidden gluten in specific brands if you have severe sensitivities.
How can I make this dish spicier?
To increase the heat, you can add more cayenne pepper to taste. Alternatively, a pinch of red pepper flakes sprinkled over the onions with the other spices, or even a few drops of your favorite hot sauce mixed with the butter, can add an extra kick.
