Notes & Wine Advice
Recipe Notes
Choose potatoes of approximately the same size and shape so they cook evenly in the air fryer. Leave a thin layer of potato inside each skin when scooping out the flesh. This helps the shells hold their shape and gives them a better texture. Cook the onions until soft, golden, and caramelized for the richest French onion flavor. Serve the potato skins immediately while the shells are crisp and the Gruyère is hot and melted.Wine Advice

Creating the French Onion Flavor
The onions are an essential part of this recipe, so give them enough time to become soft and golden. A little sugar encourages caramelization, while Worcestershire sauce and sherry vinegar provide savory depth and acidity. Fresh thyme adds the familiar herbal note that works particularly well with onion and Gruyère. Together, these ingredients turn simple potatoes into a much richer appetizer.
Getting Crispy Air Fryer Potato Skins
Cook the whole potatoes until completely tender before cutting them in half. When removing the centres, leave a thin layer of potato attached to the skins so they remain sturdy. After filling them with the onion mixture and cheese, return them to the air fryer. The second cooking stage crisps the shells while melting the Gruyère into the filling.
Serving Suggestions
Serve the potato skins immediately while they’re hot and crisp. They work particularly well as finger food for parties, Game Day, or casual gatherings. You can serve them on their own or add a fresh green salad, vegetable platter, or simple dipping sauce. A little extra fresh thyme on top also makes an attractive finishing touch.
