Ingredients

  • 4 large sweet onions (such as Vidalia)
  • 4 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk
  • 1.5 cups shredded cheddar cheese
  • 1 cup sour cream
  • 1 teaspoon salt
  • 0.5 teaspoon ground black pepper
  • 1 cup breadcrumbs
  • 0.5 cup grated Parmesan cheese
  • 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish and set it aside.

Step 2

Peel and slice the onions into thin rings. In a large skillet, melt 2 tablespoons of butter over medium heat and sauté the onions for 10-12 minutes, stirring occasionally, until they are soft and lightly golden. Set aside.

Step 3

In a medium saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add the flour and whisk continuously for 1-2 minutes to create a roux.

Step 4

Slowly pour in the milk, whisking constantly, and cook for 3-4 minutes until the mixture thickens into a creamy sauce.

Step 5

Remove the saucepan from heat and stir in the shredded cheddar cheese, sour cream, salt, and black pepper until smooth.

Step 6

Add the sautéed onions to the cheese mixture and mix gently to coat the onions evenly.

Step 7

Pour the onion and cheese mixture into the prepared casserole dish and spread it evenly.

Step 8

In a small bowl, mix together the breadcrumbs, grated Parmesan cheese, and olive oil until combined. Sprinkle the breadcrumb mixture evenly over the casserole.

Step 9

Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden and bubbling.

Step 10

Let the casserole cool for 5-10 minutes before serving. Enjoy warm as a side dish or main course.
