How To Make Easy Potato Gratin

Creating this delectable masterpiece at home is easier than you think. Follow these simple steps: First, slice potatoes thinly. Cover the potato slices with water and microwave them until tender. Drain and set aside. Next, prepare the creamy white sauce in a skillet with butter, all-purpose flour, milk, salt, pepper and parmesan cheese. Add the sliced potatoes to the creamy sauce and stir to coat evenly. Layer the slices in a baking dish. Pour your creamy sauce over the potatoes. Top with mozzarella cheese and bake it in a preheated oven for 10 minutes or until golden and bubbly. Remove the potato gratin from the oven. Let the dish rest for a few minutes and enjoy!

Cooking Tips

For the best taste, please follow my tips below.

Try to slice the potatoes evenly to ensure they cook uniformly. Using a mandoline slicer can help you achieve consistent thickness. Parboil or microwave the potato slices before layering them in the dish. This ensures they cook evenly and reduces baking time. Let the potato gratin rest for a few minutes after removing it from the oven. This helps the flavors meld and makes it easier to serve.
