Ingredients
Potatoes
- 3 pounds red potatoes, cubed into ½-inch pieces (about 6-7 cups)
- 2 tablespoons extra virgin olive oil
- 2 teaspoons kosher salt
- 2 teaspoons black pepper
French Onion Sauce
- ½ cup (1 stick / 113 g) unsalted butter, divided
- 2 large yellow onions, thinly sliced into half-moon shapes
- ½ cup (119 g) heavy whipping cream

- ¼ teaspoon black pepper
Topping
- 1 cup (100 g) parmesan cheese, grated

Instructions
Potatoes
- Preheat oven to 425°F.* Line a sheet pan with parchment paper. Spray with nonstick cooking spray.
- In a large bowl combine potatoes, oil, salt, and pepper. Toss to coat completely.
- Place potatoes onto the lined baking sheet in a single layer. Bake, uncovered, for 45-60 minutes, or until the potatoes are crispy, flipping after 30 minutes.
- While the potatoes are baking, begin to prepare the French Onion sauce.
French Onion Sauce
- In a large non-stick pan over medium-high heat, melt ¼ cup of butter.
- Once the butter has melted, add the onions and sauté them for 25-30 minutes, stirring occasionally, until they are very tender and caramelized to a rich golden brown color.
- In the last few minutes of cooking the onions, add the remaining ¼ cup butter, heavy cream, salt, and pepper.
- Once melted and warm, carefully transfer the mixture to the bowl of a food processor. Blend until combined.
- Evenly drizzle (or spoon) the French onion sauce over the roasted potatoes. Top with parmesan and Gruyere cheese.
- Increase the oven temperature to broil. Place the potatoes back into the oven until the cheese is melted (about 3 minutes).
- Serve topped with parsley for garnish.
