When gathering ingredients for this dish we suggest sticking with a Yukon or Russet potato. Either is good at holding it's shape when baked. But a plus to Yukon potatoes is that they do have a tender skin which means no need to peel!
🍳 Step-by-Step Instructions
Firstly, preheat the oven to 350° and grease a 9x13 baking dish. Then begin adding garlic, onion and butter to a pan to saute over medium heat.
Second, once onions are translucent combine cream, milk, salt, and pepper in the pan. Bring to a slow boil. When you see bubbles forming around the sides you will want to go ahead and remove from the pan from the heat and allow your cream sauce to cool for 10 minutes.
While the mixture is cooling you can thinly slice the potatoes. Potatoes need to be roughly ⅛ inch thick. Afterwards place potatoes on a paper towel to pat dry. Then layer the bottom of your greased baking dish with half of the potatoes in a single layer.
Third, pour half of the sauce mixture over the potatoes and sprinkle half of the cheeses over the top. Repeat all layers using up the remaining ingredients.
Lastly, once the dish is all assembled place pan in the oven and bake uncovered for 55-65 minutes or until potatoes are tender. Before serving be sure to allow the pan to sit for 5-10 minutes before serving so dish can come together.
