Recipe Information
Ingredients
- 4 pieces large yellow onions
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 0.5 cups heavy cream
- 0.5 cups grated Parmesan cheese
- 1 cups shredded sharp cheddar cheese
- 1 cups bread crumbs
- 2 tablespoons olive oil
- 0.5 teaspoons garlic powder
- 1 teaspoons salt
- 0.5 teaspoons black pepper
- 2 tablespoons fresh parsley (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with a small amount of butter or oil and set aside.
Peel the onions and slice them into 1/4-inch thick rings. Separate the rings and set them aside.
Bring a medium pot of water to a boil. Add the sliced onions and blanch for 3 minutes. Drain and pat dry with paper towels to remove excess moisture.
In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1-2 minutes until the mixture turns light golden and smells nutty.
Slowly whisk in the milk and heavy cream, stirring constantly to avoid lumps. Continue cooking until the mixture thickens, about 5 minutes.
Stir in the salt, black pepper, garlic powder, and Parmesan cheese. Remove from heat and let it cool slightly.
Arrange the blanched onion rings in the prepared baking dish. Pour the cheese sauce evenly over the onions, making sure they are well-coated.
In a small bowl, mix the bread crumbs, shredded cheddar cheese, and olive oil. Sprinkle the breadcrumb mixture evenly over the onion and sauce layer.
Bake in the preheated oven for 35-40 minutes, or until the top is golden brown and bubbling.
Remove from the oven and let cool for 5 minutes. Garnish with chopped parsley if desired, and serve warm.
