Ingredients

Scale

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

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
  2. 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.
  3. 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.
  4. Add Cheese: Top the onions with shredded cheddar, Monterey Jack, and grated Parmesan cheeses. Spread the cheeses evenly to ensure consistent melting.
  5. 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.
  6. Bake Uncovered: Remove the foil and continue baking for an additional 10 minutes, or until the cheese turns golden brown and bubbly.
  7. 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.
