Ingredients

The following ingredients have 6 Servings
  • 1 1/2 lbs russet potatoes (washed and peeled, sliced thin with a mandolin slicer)
  • 1 cup heavy whipping cream
  • 1/2 cup milk
  • 1/2 cup chicken stock
  • 1/2 Tbs minced garlic
  • 2 Tbs all-purpose flour
  • 1 1/2 tsp salt
  • 1 tsp ground black pepper
  • 1/4 tsp cayenne pepper
  • 1 Tbs brown mustard
  • 1 cup grated mozzarella cheese or gruyere cheese
  • 1/2 cup grated parmesan cheese
  • 1 cup grated cheddar cheese
  • Fresh Parsley

Instruction

  • Thinly slice the potatoes using a mandoline slicer. Slice thin.
  • In a medium bowl whisk together heavy cream, milk, chicken stock, garlic, flour, salt, black pepper, mustard and cayenne. Taste, and adjust taste to preference.
  • In another bowl, mix the three cheeses together, and set aside.
  • Spray a round cake pan that can easily fit inside your pressure cooker with non-stick cooking spray. For the 8 qt instant pot an 8 inch round with 2 inch sides should work. If using a smaller pressure cooker, use a 6-7 inch round with 3 inch sides.
  • Layer half of the potatoes into the round pan, followed by half of the cheese.
  • Pour half of the liquid over the top.
  • Add the remaining potatoes, and remaining liquid. But reserve cheese for after cooking time is up.
  • Pour 2 cups of water into the liner of your pressure cooker and place the trivet in the bottom, with the handles up.
  • Carefully place your round cake pan full of potatoes into the pan on top of the trivet.
  • Place the lid on your pot, and lock into place. Set the valve to sealing.
  • Cook on HIGH pressure for 35 minutes, followed by a QUICK RELEASE of the pressure.
  • Preheat oven to broil on high.
  • Carefully pull the round cake pan out by the trivet handles, and put on a baking sheet.
  • Top with the remaining cheese and place under the broiler in your oven until cheese is bubbly and starting to brown, approximately 3 minutes.
  • Let the potatoes rest for about 5 minutes to give sauce a chance to thicken, and top with fresh parsley garnish if desired, and serve.
