3. Step-by-Step Instructions to Make the French Onion Potato Bake

Preparation of the Onions and Caramelization

Preheat your oven to 375°F (190°C). In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onions and cook slowly, stirring occasionally, until they are golden brown and caramelized—about 20-30 minutes. Add the minced garlic and thyme, cooking for another minute. Season with salt and pepper, then set aside.

Layering the Potatoes and Onion Mixture

In a greased baking dish, layer half of the sliced potatoes, then spread half of the caramelized onions evenly over the potatoes. Sprinkle with half of the shredded cheese. Repeat with the remaining potatoes, onions, and cheese.

Preparing the Cream Mixture

In a small bowl, mix the sour cream with a pinch of salt, pepper, and a touch of thyme if desired. Drizzle this mixture evenly over the layered potatoes and onions.

Baking the Potato Casserole

Cover the baking dish with foil and bake for 35-40 minutes, or until the potatoes are tender. Remove the foil, sprinkle some breadcrumbs if using, and bake uncovered for an additional 10 minutes until golden and bubbly. Let it rest for 5 minutes before serving.
