Ingredients needed

• 8 small onions (approximately 600 g)
• 50g of breadcrumbs
• 20g of grated Parmesan cheese

• Fresh chopped parsley to taste
• Olive oil or seed oil
• Ground black pepper
• Salt

Step-by-step preparation

1. Prepare the onions :
   Peel the small onions and cut them in half. If they are very small, you can leave them whole. Wash them and dry them well with a clean cloth.
2. Pre-seasoning :
   Place the onions in a bowl and add a drizzle of olive or vegetable oil. Add salt, black pepper, and chopped parsley to taste. Mix well to combine the flavors.
3. First cooking :
   Place the onions in the air fryer and cook at 160°C for 30 minutes. This step softens them and begins to lightly caramelize the outside.
4. Add the gratin :
   Once cooked, sprinkle the breadcrumbs and Parmesan cheese over the onions.
5. Second cooking for gratinating :
   Place the onions back in the air fryer and cook at 180°C for another 10 minutes, or until the breadcrumbs and cheese are golden brown and crispy.

Additional tips

• Cheese variation : If you don’t have Parmesan, you can use any grated hard cheese such as Grana Padano or Pecorino. Even a blend of cheeses can give a richer flavor.
• Aromatic touch : Add a little garlic powder or onion powder to the breadcrumbs before sprinkling for a more intense flavor.
• Presentation : Serve the onions on a platter decorated with more fresh parsley and a drizzle of raw olive oil on top.
• Spicy version : Add a pinch of ground chili or hot paprika to the breadcrumbs to give them a different touch.

These gratinéed onions are a creative way to enjoy this versatile vegetable. Thanks to the air fryer, the result is both flavorful and light.
