Ingredients
  

  • 900 grams 2 pounds of large russet potatoes, peeled and sliced into 1/4 inch thick rounds
  • 1 yellow onion thinly sliced into rings
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 1/2 teaspoon kosher salt
  • 475 mL 2 cups whole milk, room temperature
  • 170 grams 1 1/2 cups mild cheddar cheese, shredded
  • Salt and pepper to taste

Instructions
 

  • Preheat your oven to 200°C (400°F). Grease an 8x8 inch casserole dish lightly with nonstick cooking spray.
  • In the greased baking dish, arrange the russet potato slices and onion rings, ensuring an even layer of both.
  • Over medium heat, melt the butter in a saucepan. Add in the flour and kosher salt, whisking continuously for about a minute.
  • Slowly pour in the milk, continuing to whisk until the mixture thickens into a smooth sauce.
  • Add the shredded cheddar cheese, stirring until the cheese has completely melted and the sauce is creamy.
  • Pour the cheese sauce over the potatoes and onions, making sure they're evenly coated.
  • Cover the casserole dish with foil and bake in the preheated oven for about 90 minutes, or until the potatoes are tender.
  • For a beautiful golden crust, remove the foil, switch the oven to broil, and broil the dish for a few minutes.
  • Season the Heavenly Cheesy Scalloped Potatoes with additional salt and pepper to taste, and serve hot.

Notes
