3. How to Make the Ultimate French Onion Potato Bake

Step 1: Prepare the potatoes

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or nonstick spray. Arrange the sliced potatoes evenly in the dish.

Step 2: Caramelize the onions

In a large skillet, heat 1 tablespoon of olive oil and 2 tablespoons of butter over medium heat. Add the sliced onions, a pinch of salt, and cook slowly, stirring frequently, until they turn golden brown and caramelized (about 20-25 minutes). Add minced garlic and thyme during the last 2 minutes of cooking.

Step 3: Layer the ingredients

Spread the caramelized onions evenly over the potato slices. Season with salt and pepper as needed. For an extra layer of flavor, sprinkle some chopped fresh herbs if desired.

Step 4: Add cheese and sour cream

Sprinkle the shredded cheese liberally over the onions. Dollop the sour cream or Greek yogurt over the cheese, then bake uncovered in the preheated oven for 35-40 minutes or until the potatoes are tender and the cheese is bubbling and golden.

Step 5: Serve and enjoy

Garnish with fresh parsley and serve hot for a delicious French Onion Potato Bake that everyone will love. This dish pairs beautifully with roasted meats or a fresh green salad.
