Ingredients

Scale

Onions

  • 4 large sweet onions
  • 2 red onions

Cheese

  • 1 cup cheddar cheese, shredded
  • 1/2 cup monterey jack cheese, shredded
  • 1/4 cup parmesan cheese, grated

Seasonings and Additional Ingredients

  • 2 tbsp butter
  • 1 tsp garlic powder
  • 1/2 tsp black pepper
  • 1/4 tsp salt
  • 2 tbsp chopped fresh parsley
  • 1/4 cup heavy cream
  • 1/3 cup breadcrumbs

Instructions

  1. Preheat the oven to 375°F and prepare a baking dish by lightly greasing it with butter or cooking spray.
  2. Carefully slice sweet and red onions into thick rings, separating the layers gently to maintain their structural integrity.
  3. Arrange the onion rings in a single layer within the prepared baking dish, ensuring they are evenly distributed.
  4. Sprinkle garlic powder, black pepper, and salt across the onion rings to enhance their natural flavors.
  5. Drizzle melted butter and heavy cream over the seasoned onions, allowing the liquid to seep between the layers.
  6. Create a generous cheese blend by mixing cheddar, monterey jack, and parmesan cheeses, then evenly distribute the mixture across the onions.
  7. Dust the top with breadcrumbs, creating a crispy golden layer that will provide textural contrast.
  8. Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the onions become tender and the cheese melts into a bubbly, golden crust.
  9. Remove from the oven and let the dish rest for 5 minutes to allow the flavors to meld and settle.
  10. Garnish with freshly chopped parsley for a bright, herbal finish before serving hot.

Notes

  • Choose sweet onions like Vidalia for a milder, more caramelized flavor that melts in your mouth.
  • Slice onions uniformly to ensure even cooking and consistent texture throughout the dish.
  • Experiment with cheese varieties like gruyère or gouda for a more complex and rich taste profile.
  • For a gluten-free version, swap breadcrumbs with crushed pork rinds or almond flour to maintain the crispy topping.
