Preheat your oven to 375°F. This step is crucial for achieving that golden brown finish on your cake.
In a medium mixing bowl, add the sliced potatoes. They should be thin so they cook evenly and provide a nice texture.
Next, add the finely chopped onion to the bowl. The sweetness of the onion will enhance the flavor of the potatoes.
Pour in the melted butter. This will help bind the ingredients together and add richness to the cake.
Sprinkle in the dried Italian herbs, along with a generous amount of salt and pepper. These seasonings are essential for bringing out the flavors.
Mix everything very well until all the ingredients are evenly coated with the butter and seasonings.
Prepare a 9-inch springform pan by lining it with parchment paper. This will prevent sticking and make for an easy cleanup.
Carefully transfer the potato mixture into the prepared springform pan. Spread it out evenly so that it cooks uniformly.
Place the pan in your preheated oven and bake for about 50 to 55 minutes. You’ll want to keep an eye on it; the potatoes should be golden brown and cooked through.
Once done, remove the cake from the oven and let it cool slightly before serving. This will help it firm up a bit for easier slicing.
