Ingredients

  • 5 med-large russet or Idaho potatoes peeled, ⅛-1/4 inch slices
  • 1 large onion, diced
  • 2 tblsp garlic, minced
  • 2 cups cheddar , shredded to taste
  • 1 cup parmesan cheese, grated or shredded to taste
  • ½ cup chicken broth
  • 1 cup heavy cream
  • 3 tblsp unsalted butter
  • 1 tblsp thyme, dried
  • 2 teaspoon salt
  • 1 teaspoon pepper

Topping

  • ½ cup parmesan more or less to taste
  • ½ cup cheddar more or less to taste

Instructions

  • Slice your potatoes to between ⅛ and ¼ inch thick. Rinse and set aside.
  • Preheat your oven to 425 degrees.
  • Melt butter in large pot over medium heat. Add onion and cook until tender, stirring occasionally, about 5 minutes. Add garlic, thyme, salt, and pepper. Stir. Add potatoes, chicken broth and cream.
  • Cover, reduce heat to medium-low, and simmer until potatoes are almost tender, about 10 minutes.
  • Dump mixture into a bowl, or just use the same pot OFF HEAT, and add cheeses and gently stir until blended. You want the cheese spread evenly throughout the dish. Taste to make sure you don't want to add more salt or pepper.
  • Transfer mixture to an 9x13 inch baking dish or the equivalent. Press into an even layer. Sprinkle evenly with cheese of your choice. We always put the cheddar on first and the parmesan on top.
  • Bake until cream is bubbling around edges and top is golden brown, about 15 minutes. Broil if necessary to brown the cheese to your liking. Allow to stand or rest for 10 minutes before serving.
  • NOTE: Ultimately, baking time will depend on how thinly you were able to slice your potatoes so please adjust your cooking time accordingly. Poke your potato dish with a knife or fork and once your potatoes are tender, and the cheese is melted to your liking on top, your dish is ready to eat!

Notes

    • Potato Slices: Aim for between ⅛ and ¼ of an inch thick. The thinner the slices, the faster they will all cook. It's also important for the slices to be as close to the same size as possible.
    • How to Slice: To slice your potatoes perfectly use a sharp knife, a slicing blade attachment on your food processor, or a mandolin for the best results.
    • Baking Dish Size: Use a shallow casserole dish to ensure a quicker cooking and reheating time.
    • Checking for Doneness: Poke the potatoes with a knife or fork to determine if they are ready. The fork should easily penetrate the potato without any resistance.
    • Adjust the Seasoning: Taste the potato sauce before adding it to the casserole dish to make sure you don't want to add more salt or pepper.
    • More Crispy Top: Broil at the end of baking to brown the cheese on top.
    • Select the Right Potato: Use either Russets or Yukon Gold potatoes for the best texture. They hold their shape well and have the perfect starch content for scalloped potatoes.
    • Grate Your Own Cheese: For a smoother melt and more flavorful dish, grate cheese instead of buying pre-shredded cheese.
