How to Make Potato Au Gratin
Preheat your oven to 375 °F (190 °C). This will ensure your potato au gratin bakes evenly and becomes beautifully golden brown on top.
Slice the Russet potatoes and onion thinly. Aim for even slices, about 1/8 inch thick, for the best texture and consistent cooking.
Combine the heavy cream, minced garlic, salt, and black pepper in a mixing bowl. Whisk together until well blended, allowing the flavors to infuse into the cream.
Layer the sliced potatoes and onions in a greased baking dish. Start with a layer of potatoes, sprinkle some onions, and then drizzle with the cream mixture. Repeat until all ingredients are used, finishing with a layer of cream.
Sprinkle the Gruy re and Parmesan cheeses generously over the top. This will create that delightful, gooey layer everyone loves while baking.
Top with breadcrumbs for added crunch. If you re using panko, you ll get an extra crispy finish that contrasts beautifully with the creamy potatoes.
Bake in the preheated oven for 45-50 minutes, or until the top is golden and the potatoes are tender when pierced with a fork.
Cool for a few minutes before serving. This allows the layers to set slightly, making it easier to scoop onto plates without falling apart.
Optional: Garnish with fresh herbs like parsley or chives for a pop of color and flavor!

Helpful Tricks for Potato Au Gratin
Uniform Slicing: Ensure the potatoes are sliced evenly (about 1/8 inch) for consistent cooking. This helps avoid uneven textures in your potato au gratin.
Infuse the Cream: Allow the garlic, salt, and pepper to sit in the cream for a few minutes before layering. This helps to maximize flavor and infuse a beautiful taste throughout the dish.
Cheese Choices: Don t hesitate to experiment with cheese! While Gruy re is traditional, mixing in your favorite cheeses can create a delicious twist on this classic comfort food.
Breadcrumb Crunch: For an extra crispy topping, toast the breadcrumbs lightly before sprinkling them over the cheese. This gives a delightful crunch to your potato au gratin.
Let It Rest: Allow your dish to cool for a few minutes after baking. This helps the layers set properly, making it easier to serve and enjoy!
Garnish Generously: Fresh herbs like chives or parsley not only enhance flavor but add a beautiful touch of color, elevating the presentation of your potato au gratin.
