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.

Notes

*Air Fryer Roasted Potatoes
Prepare the potatoes as instructed.
Place the potatoes into the basket of your air fryer in a single layer. (Depending on the size of your air fryer, you may have to work in batches.)
Air Fry at 380°F for 20-25 minutes, or until evenly crisped, flipping halfway through.
