Method
 

Step 1 – Caramelize the Onions
  1. In a large skillet, heat 2 tbsp vegetable oil and 2 tbsp butter over medium heat. Add the sliced onions with a pinch of salt.
  2. Cook slowly for 20–25 minutes, stirring often, until golden brown and deeply caramelized. Add the garlic and cook another 30 seconds. Set aside to cool slightly.
Step 2 – Prepare the Creamy Base
  1. In a medium saucepan, melt the remaining butter over medium heat. Whisk in the flour and cook for 1 minute to form a roux.
  2. Slowly pour in the chicken broth and milk, whisking constantly until smooth and slightly thickened.
Step 3 – Add Seasoning
  1. Stir in salt, black pepper, cayenne pepper, and dry mustard powder. Remove from heat and let cool slightly.
Step 4 – Combine the Main Ingredients
  1. In a large mixing bowl, add the thawed hash browns, sour cream, caramelized onions, cheddar cheese, Parmesan, and the creamy sauce. Stir gently until everything is evenly coated.
Step 5 – Transfer to Baking Dish
  1. Spread the mixture evenly into a greased 9×13-inch casserole dish. Smooth the top with a spatula.
Step 6 – Bake Until Golden
  1. Bake uncovered for 40–45 minutes, or until the casserole is bubbling and golden on top.
  2. For an extra crispy crust, broil for the last 2–3 minutes.
Step 7 – Cool & Serve
  1. Allow to rest for 10 minutes before serving so the creamy sauce thickens perfectly. Garnish with fresh parsley or extra caramelized onions if desired.
