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
- Preheat the oven to 375°F and prepare a baking dish by lightly greasing it with butter or cooking spray.
- Carefully slice sweet and red onions into thick rings, separating the layers gently to maintain their structural integrity.
- Arrange the onion rings in a single layer within the prepared baking dish, ensuring they are evenly distributed.
- Sprinkle garlic powder, black pepper, and salt across the onion rings to enhance their natural flavors.
- Drizzle melted butter and heavy cream over the seasoned onions, allowing the liquid to seep between the layers.
- Create a generous cheese blend by mixing cheddar, monterey jack, and parmesan cheeses, then evenly distribute the mixture across the onions.
- Dust the top with breadcrumbs, creating a crispy golden layer that will provide textural contrast.
- 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.
- Remove from the oven and let the dish rest for 5 minutes to allow the flavors to meld and settle.
- 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.
