Infused with garlic, thyme, and butter, this comforting dish offers a perfect balance of sweet and savory flavors, topped with a golden, bubbly cheese crust.

Ingredients

Main Ingredients

  • 3 large sweet onions (such as Vidalia), sliced into ½-inch rings
  • 1 ½ cups shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • ½ cup grated Parmesan cheese
  • 4 tablespoons unsalted butter, melted
  • 1 teaspoon garlic powder
  • ½ teaspoon dried thyme
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Instructions

  1. Preheat the oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prevent sticking and ensure even cooking.
  2. Prepare the onions: Arrange the sliced sweet onions in an even layer in the prepared baking dish, making sure to separate the rings for uniform cooking and cheese coverage.
  3. Add seasoning and butter: Drizzle the melted unsalted butter evenly over the onions. Then sprinkle garlic powder, dried thyme, salt, and black pepper on top to infuse the onions with flavor.
  4. Layer the cheeses: Evenly top the onions with the shredded cheddar, Monterey Jack, and grated Parmesan cheeses to create a rich and melty cheese crust.
  5. Bake covered: Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. This allows the onions to soften and the flavors to meld without the cheese overbrowning.
  6. Bake uncovered: Remove the foil and continue baking for another 10 minutes, or until the cheese is golden brown and bubbly, providing a delicious crispy cheese topping.
  7. Cool and serve: Let the dish cool slightly before serving to allow the cheese to set a bit. Serve warm as a tasty side dish to complement various mains.

Notes

  • Use sweet onions like Vidalia for the best natural sweetness and flavor.
  • To prevent sticking, ensure the baking dish is thoroughly greased or use parchment paper.
  • For a sharper flavor, consider substituting some cheddar cheese with smoked cheddar.
  • You can prepare the onions ahead and refrigerate before baking, then bake just before serving.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently in the oven.
