Ingredients
- 1 (30 oz) package frozen shredded hash brown potatoes, thawed
- 4 Tbsp Butter, diced into 1 Tbsp pieces
- 1/2 cup finely chopped yellow onion
- 1/4 cup all-purpose flour
- 2 3/4 cups milk (whole or 2%)
- 1 1/2 cups shredded sharp cheddar cheese
- 1/2 cup finely shredded Parmesan cheese
- 1 cup sour cream
- Salt and freshly ground pepper
- 4 cups cornflakes, crushed (nearly 2 cups once crushed)
- 3 Tbsp Butter, melted
- 1 1/2 Tbsp chopped fresh parsley
Instructions
- Preheat oven to 350 degrees.
- Melt 4 Tbsp butter in a large saucepan over medium heat. Add onion and saute until softened, about 5 - 6 minutes.
- Add in flour and cook stirring constantly, 1 minute. While whisking pour in milk then cook stirring constantly until mixture comes to a boil.
- Remove from heat, add in cheddar cheese and parmesan cheese and stir until melted.
- Stir in sour cream. Season mixture with salt and pepper to taste (you want it on the salty side as it will be seasoning the potatoes).
- Place hash browns in a large mixing bowl then pour in milk mixture and toss to evenly coat. Transfer to a 13 by 9-inch baking dish (no need to grease dish) and spread into and even layer.
- Place cornflakes in a gallon size resealable bag, seal bag and crush with a rolling pin to roughly pebble size bits.
- Add 3 Tbsp melted butter to cornflake mixture then seal bag and toss to evenly coat with butter. Sprinkle cornflake mixture evenly over casserole.
- Bake in preheated oven until hot throughout, about 40 - 50 minutes. Garnish with parsley and serve warm.
