  2. 2

    Pour the mixture into a 2 quart casserole dish.  Sprinkle with the remaining Parmesan cheese.  Cover with foil. Bake for 1 hour or until the potatoes are tender (time can vary depending on how thickly the potatoes are sliced).Uncover and bake for another 20 minutes or until the top is lightly browned and to enable excess moisture to evaporate.Let sit for about 5 minutes before serving (if you used a lower starch potato variety like Yukon Gold it will be "soupier" and may need to sit a few minutes longer to enable the excess liquid to absorb).  Sprinkle with some chopped parsley for garnish if desired.

This recipe offers au gratin potatoes at their very best, promising a truly memorable addition to your dinner table.

This recipe achieves its rich, velvety texture and deep flavor through a harmonious blend of whole milk and heavy cream, combined with both sharp cheddar and salty Parmesan cheese. The carefully chosen moderate starch potatoes ensure each slice becomes beautifully tender without dissolving, perfectly absorbing the luxurious sauce. The meticulous preparation ensures every bite is pure comfort and flavor.

Prepare for a decadent side dish featuring tender, thinly sliced potatoes swimming in a luxurious, savory sauce. Each forkful offers a delightful balance of earthy potato and the sharp, nutty notes of two distinct cheeses, subtly enhanced by the aromatic yellow onion and minced garlic. The result is a deeply satisfying, wonderfully creamy, and intensely flavorful experience, perfect for elevating any dinner table. While preparation is straightforward, the generous cooking time allows all those wonderful flavors to meld beautifully, creating a depth that truly sets this dish apart.

While this recipe is perfect as written, you can easily tailor it to your preference. Feel free to experiment with different hard cheeses like Gruyère or Monterey Jack for unique flavor profiles in place of or in addition to the cheddar and Parmesan. For a milder flavor, you can omit the black pepper, or adjust the amount of onion and garlic to suit your taste.
