Let’s Make it together
Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This ensures everything cooks evenly and beautifully.
Sauté the Onions: In a large skillet over medium heat, melt butter and add sliced onions. Cook until they’re soft and translucent with a sweet aroma filling your kitchen—about 15-20 minutes.
Prepare Potatoes: While the onions are cooking, slice your potatoes thinly using a mandoline or sharp knife. Aim for uniform slices so they cook evenly!
Layer Ingredients in Baking Dish: In a greased baking dish, layer half of the potatoes followed by half of the sautéed onions. Sprinkle some thyme leaves between layers for added flavor.
Add Cream and Cheese Mixture: In a bowl, combine heavy cream with salt and pepper. Pour half over your layered potatoes and onions. Top generously with shredded cheese before repeating layers with remaining ingredients.
Bake Until Golden Brown: Cover with foil and bake for 30 minutes. Remove foil for the last 15 minutes or until bubbly and golden brown on top—this is when you can fully enjoy that cheesy goodness!
Make sure to let it cool slightly before serving; nobody wants third-degree burns from molten cheese!
Now you have an irresistible French Onion Potato Bake that’s sure to impress anyone lucky enough to dig into this culinary masterpiece!
