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)

Directions

Step 1

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.

Step 2

Peel the onions and slice them into 1/4-inch thick rings. Separate the rings and set them aside.

Step 3

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.

Step 4

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.

Step 5

Slowly whisk in the milk and heavy cream, stirring constantly to avoid lumps. Continue cooking until the mixture thickens, about 5 minutes.

Step 6

Stir in the salt, black pepper, garlic powder, and Parmesan cheese. Remove from heat and let it cool slightly.

Step 7

Arrange the blanched onion rings in the prepared baking dish. Pour the cheese sauce evenly over the onions, making sure they are well-coated.

Step 8

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.

Step 9

Bake in the preheated oven for 35-40 minutes, or until the top is golden brown and bubbling.

Step 10

Remove from the oven and let cool for 5 minutes. Garnish with chopped parsley if desired, and serve warm.
