Onions
- 3 large sweet onions (such as Vidalia), sliced into ½-inch rings
Cheese Mixture
- 1 ½ cups shredded cheddar cheese
- 1 cup shredded Monterey Jack cheese
- ½ cup grated Parmesan cheese
Seasoning & Butter
- 4 tablespoons unsalted butter, melted
- 1 teaspoon garlic powder
- ½ teaspoon dried thyme
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Preheat Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
- Prepare Onions: Arrange the sliced sweet onions in an even layer in the prepared baking dish, making sure to separate the rings for even cooking.
- Season: Drizzle the melted unsalted butter evenly over the onions. Sprinkle garlic powder, dried thyme, salt, and black pepper across the onions to distribute the seasoning uniformly.
- Add Cheese: Top the onions with shredded cheddar, Monterey Jack, and grated Parmesan cheeses. Spread the cheeses evenly to ensure consistent melting.
- Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 25 minutes to cook the onions and melt the cheese.
- Bake Uncovered: Remove the foil and continue baking for an additional 10 minutes, or until the cheese turns golden brown and bubbly.
- Cool and Serve: Allow the Tennessee Onions to cool slightly before serving. Enjoy them as a delicious, cheesy side dish.
Notes
- For best results, use sweet onions like Vidalia for natural sweetness and flavor.
- Ensure onions are sliced evenly to promote uniform cooking.
- Covering the dish during the first bake helps melt the cheese and soften onions while preventing cheese from burning.
- Removing the foil for the last 10 minutes enhances browning and creates a bubbly cheese topping.
- This dish pairs well with grilled meats or roasted poultry.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven.
