Potatoes au Gratin

on

Yield: 6 servings

We made this as a side dish with Roast Duck.

Ingredients

  • 5 large russet potatoes, peeled
  • 1 cup shredded cheddar cheese
  • 1 cup shredded swiss cheese
  • 1 cup shredded parmesan cheese
  • 4 tsp cornstarch
  • Salt
  • Pepper
  • Garlic powder
  • Onion powder
  • 1/3 cup chicken stock
  • 1/2 cup heavy whipping cream

Directions

  1. Slice the potatoes thinly (1/8") on a mandolin.  Set aside the potatoes, but don't soak in water -- we don't want to lose any starch.
  2. In a large mixing bowl, combine the cheeses and cornstarch.  Toss together to mix well.
  3. In an 8" square baking pan, place one layer of potato slices with them overlapping generously.  Salt and pepper the potatoes generously.  Apply the garlic and onion powders.  Place layer two of potato slices perpendicular to layer one.  Sprinkle in 1/4 of the cheese mixture.
    • Think about how much salt you'd use on five large baked potatoes.  That's how much you should be using total over the next few steps.
  4. Repeat step #3 again, placing layer 3, seasonings, layer 4, and another 1/4 of the cheese.
  5. Place layer 5, seasonings, and layer 6.  Set aside.
  6. In a small mixing bowl, mix together the chicken stock and whipping cream.  Pour over the potato dish.  Top with the remaining 2/5 of the cheeses.
  7. Cover with aluminum foil and bake at 325°F for 45 minutes.  Remove the foil and bake for another 45 minutes.
  8. Remove from the oven and poke with a toothpick.  The potatoes should be soft enough to poke through, but still mildly firm.  Cover with foil and set aside to rest for 60-90 minutes.  The sauces will thicken and it will serve more firmly.
  9. Cut into squares and serve warm.
