Ingredients

  • 500 gms medium potatoes

For the Bechamel sauce

  • 3 tbsp butter
  • 3 tbsp all-purpose flour
  • 2 cups milk
  • 1/2 cup heavy cream
  • 1 tsp salt or to taste
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/4 tsp black pepper powder
  • 2 cups grated cheddar cheese

Instructions

  • To begin, thinly slice the potatoes using a mandoline to ensure equal thickness. Soak them in water so that they do not colorize.
  • To prepare the Bechamel sauce, melt butter on medium heat in a saucepan.
  • Add in the flour whisking constantly until cooked. Do not brown.
  • Next, add in the milk and the cream whisking constantly making sure no lumps are formed.
  • Now add in the seasoning – salt to taste, garlic powder, onion powder, and black pepper powder. Simmer until the sauce thickens and coats the back of the spoon.
  • Turn off the heat. Add in the cheese. Fold it in until the cheese melts. Keep aside.
  • In the meantime, preheat the oven to 180°C or 350°F.
  • To assemble, grease the baking dish with butter. Stack the potato slices and arrange them in rows. Pour the cheesy Bechamel sauce on top.
  • Cover with aluminum foil and bake in a preheated oven at 180°C or 350°F for 25-30 minutes.
  • Remove the foil. Sprinkle some grated cheese on top. Bake it for another 20-25 minutes until done and the sauce and cheese colorize.
  • Remove from oven and let it stand for 5-10 minutes so that the sauce settles.
  • The Potatoes Au Gratin is ready to serve.

Notes

  • Keep the potato skin on for extra crispness.
  • Don’t worry if you see the cheese and milk separate after baking. They will bind together once the sauce settles.
