2. Ingredients for the French Onion Potato Bake

• 4 large russet potatoes, thinly sliced
• 2 large onions, sliced
• 2 cups shredded Gruyère or Swiss cheese
• 1 cup sour cream or Greek yogurt
• 1/2 cup butter
• 2 tablespoons olive oil
• 2 cloves garlic, minced
• 1 teaspoon fresh thyme or rosemary
• Salt and black pepper to taste
• Fresh parsley for garnish

3. Step-by-Step Instructions to Prepare the Cheesy Onion Potato Casserole

Step 1: Caramelize the Onions

In a large skillet, heat butter and olive oil over medium heat. Add sliced onions and a pinch of salt, cooking slowly until they become golden and caramelized, about 15-20 minutes. Stir occasionally to prevent burning. Once done, set aside.

Step 2: Prepare the Potatoes

Wash and thinly slice the potatoes evenly. To ensure easy layering, you can use a mandoline slicer for uniform slices. Season with salt, pepper, and minced garlic.

Step 3: Assemble the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or non-stick spray. Layer half of the sliced potatoes, followed by half of the caramelized onions, cheese, and herbs. Repeat the layers, finishing with cheese on top.

Step 4: Add the Creamy Mixture

In a bowl, combine sour cream or Greek yogurt with a little salt, pepper, and herbs. Spread this mixture evenly over the layered potatoes and cheese. This adds creaminess and enhances flavor.

Step 5: Bake the French Onion Potato Bake

Cover the dish with foil and bake for 45-50 minutes. Remove the foil during the last 10 minutes to allow the cheese to brown and bubble. Let it rest for 5 minutes before serving.

4. Storage Tips for Leftover French Onion Potato Casserole

Allow the casserole to cool completely, then store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 15-20 minutes until heated through. This dish re-heats well, maintaining its creamy and cheesy texture.
