Equipment

Ingredients

  • 4 medium Russet potatoes thinly sliced
  • 2 tablespoon Butter
  • 1 cup Parmesan cheese grated
  • 1 cup Cheddar cheese grated  (gruyere, colby, swiss)
  • 1 pint Heavy cream 2 cups
  • 1 teaspoon Garlic powder optional
  • 1 teaspoon Onion powder
  • ½ teaspoon Black pepper powder adjust to taste
  • ¼ teaspoon Cayenne powder optional
  • ¾ to 1 teaspoon Salt adjust to taste
  • 1 tablespoon Fresh herb finely chopped (thyme, cilantro or parsley)

Instructions

  • Preheat the oven to 350 degrees F. Grease a 9-inch by 9-inch pan using 1 tablespoon butter.
    2 tablespoon Butter
  • In a bowl, add heavy cream, garlic powder, onion powder, black pepper powder, cayenne powder, and mix.
    1 pint Heavy cream, 1 teaspoon Garlic powder, 1 teaspoon Onion powder, ½ teaspoon Black pepper powder, ¾ to 1 teaspoon Salt, ¼ teaspoon Cayenne powder
  • Add a layer of thinly sliced potatoes, edges overlapping, into the greased baking pan. Top it with ⅓ portion of the cream mixture. Follow this with ⅓ portion of cheddar and parmesan cheese.
    1 cup Parmesan cheese, 1 cup Cheddar cheese, 4 medium Russet potatoes
  • Repeat the above process for two more layers. 
  • Finally, dot the top with the remaining 1 tablespoon of butter.
    2 tablespoon Butter
  • Cover the pan with aluminum foil and bake this for 55 minutes covered.
  • Remove the foil and bake uncovered for an additional 10 minutes or until lightly browned and a knife pierces easily through the potatoes.
  • Remove from the oven and rest it for 10 minutes.
  • The best potatoes au gratin recipe is ready. Serve warm for your dinner, and enjoy.
    1 tablespoon Fresh herb

Notes

  • See that the potatoes are covered in heavy cream so that gratin doesn't dry out.
  • Cover the baking dish with aluminum foil, which will help the potatoes remain soft and tender.
  • Do you love more garlicky flavor? You can roast 4 to 5 garlic cloves and then add them to the cream sauce.
  • You can also sautee the onions and mushrooms and add them between each layer. This will only enhance the taste of the dish.
  • Store the leftover gratin in the refrigerator for 2-3 days. Reheat in the oven at 350 degrees F for 20 minutes or until heated through.
