Follow these simple steps to prepare this delicious French Onion Potato Bake:

Step 1: Caramelize Onions Start by melting butter and olive oil in a skillet over medium heat, then add thinly sliced onions along with salt and optional sugar to enhance caramelization. Stir occasionally until they turn golden brown and soft, about 20-25 minutes.

Step 4: Add Creamy Mixture In a bowl, combine heavy cream or milk with additional salt and pepper before pouring half over the layered potatoes and onions in your baking dish for added creaminess.

Step 5: Repeat Layers & Finish Topping Repeat layering with remaining ingredients—potatoes, onions, cheeses—then pour remaining creamy mixture on top before finishing off with extra Parmesan cheese for that perfect golden crust.

Step 6: Bake Until Golden Brown Cover your baking dish with foil and bake at 375°F (190°C) for about 45 minutes, then remove foil and bake for another 15-20 minutes until bubbly and golden brown on top; let it rest before serving!
