Ingredients You’ll Need
These ingredients are mostly pantry staples you likely have on hand. Fresh, sweet onions are the star of the show here.
- 3 large sweet onions (such as Vidalia or Walla Walla), peeled and sliced into 1/4-inch rings
- 1 teaspoon garlic powder
- 1 teaspoon Italian seasoning
- 1 teaspoon kosher salt
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon freshly ground black pepper
- 1/4 teaspoon cayenne pepper
- 4 tablespoons unsalted butter, cut into 1/2-inch cubes
- 1 cup sharp cheddar cheese, shredded
- 1 cup mozzarella cheese, shredded
- 1/2 cup Parmesan cheese, freshly grated
- Non-stick cooking spray
Step-by-Step
- Preheat the oven to 350°F (175°C) and lightly coat a 9×13-inch baking dish with non-stick cooking spray.
- Separate the sliced onion rings and place them in a large mixing bowl.
- Sprinkle the onions with garlic powder, Italian seasoning, kosher salt, smoked paprika, black pepper, and cayenne pepper. Toss gently to ensure all rings are evenly coated.
- Arrange half of the seasoned onion rings in an even layer across the bottom of the prepared baking dish.
- Distribute half of the cubed butter, half of the cheddar cheese, and half of the mozzarella cheese over the first layer of onions.
- Repeat the layering process with the remaining onions, followed by the remaining butter, cheddar, and mozzarella. Finish by sprinkling the grated Parmesan cheese evenly over the top.
- Cover the dish tightly with aluminum foil and bake in the center of the oven for 30 minutes.
- Remove the foil and continue baking for another 30 minutes, or until the onions are tender and the cheese is golden brown and bubbling.
- Allow the dish to rest for 5 minutes before serving to let the cheese set slightly.
Best Ways to Enjoy It
Serve these onions warm alongside a juicy steak or roasted chicken. They also pair beautifully with a crisp green salad. The cheesy sauce is perfect for dipping crusty bread into. Set the table and enjoy this with your favorite people tonight.
Storage & Reheating
Store any leftovers in an airtight container in the fridge. They will stay fresh for up to four days. Reheat them in a 350°F oven for about 15 minutes. This helps the cheese get bubbly and delicious again. Avoid the microwave to keep the texture from getting soggy.
Tips for Best Results
- Don’t skip the resting time after the onions come out.
- Avoid using white onions as they can be too sharp.
- Use freshly grated Parmesan for the best melting results.
- Slice your onions into uniform rings for even cooking.
- For Thanksgiving, double the batch to feed a larger crowd.
- Add a pinch of fresh parsley for a pop of color.
Ways to Switch It Up
- Use dairy-free cheese shreds for a vegan-friendly version.
- Swap the cayenne for extra paprika for a milder flavor.
- Add sliced bell peppers for a colorful, seasonal twist.
- Top with buttery cracker crumbs for an extra crunch.
FAQs
Can I make these onions ahead of time?
Yes, you can prep the dish a day early. Keep it covered in the fridge until you are ready. Just add a few extra minutes to the baking time.
Do I have to use Vidalia onions?
Any sweet onion variety will work perfectly for this. Look for Walla Walla or Texas Sweets at your store. They provide the best caramelized flavor after baking.
I hope these Tennessee Onions bring a little Southern warmth to your kitchen. They are truly the ultimate comfort side dish for any occasion. Happy cooking!
