Ingredients

• 2 large Yellow onions
• 2 tablespoons Olive oil
• 1 tablespoon Unsalted butter
• 4 medium Russet potatoes
• 2 cups Heavy cream
• 2 minced Garlic cloves
• 6 ounces Goat cheese
• 1 teaspoon Thyme
• 1 teaspoon Salt
• 0.5 teaspoons Ground black pepper
• 0.5 cup Parmesan cheese

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or nonstick cooking spray.

Step 2

Peel and thinly slice the onions. Heat a skillet over medium heat, add olive oil and butter, and sauté the onions for 20-25 minutes, stirring occasionally, until they are soft and golden brown. Remove from heat and set aside.

Step 3

While the onions caramelize, peel the potatoes and slice them into thin rounds (about 1/8 inch thick) using a sharp knife or a mandoline slicer.

Step 4

In a small saucepan over medium heat, combine heavy cream, minced garlic, thyme, salt, and ground black pepper. Heat until warm, but do not let it boil. Remove from heat and set aside.

Step 5

Arrange one-third of the potato slices in an even layer at the bottom of the prepared baking dish. Top with half of the caramelized onions and crumble one-third of the goat cheese over the onions.

Step 6

Repeat the layers with another one-third of the potatoes, the remaining half of the onions, and another one-third of the goat cheese.

Step 7

Finish with the remaining potatoes on top, then pour the warm cream mixture evenly over the entire dish.

Step 8

Crumble the remaining goat cheese over the top layer of potatoes, then sprinkle with grated Parmesan cheese.

Step 9

Cover the baking dish tightly with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 20 minutes, or until the top is golden brown and the potatoes are tender.

Step 10

Remove from the oven and let the gratin rest for 10 minutes before serving. Garnish with fresh thyme if desired.
