French Onion Pie Made in Air Fryer

Ingredients for your French onion cakes 🍳🧅🧀

2 sheets of shortcrust pastry, freshly thawed 🥧
1 tablespoon olive oil 🫒
1 small brown onion, cut into thin slices 🧅
75 g cream cheese 🧀
2 tablespoons sour cream 🥄
25 g (¼ cup) grated cheddar cheese 🧀
3 large eggs 🥚
Chopped fresh chives, to serve (optional) 🌿

Step-by-step preparation in an air fryer ⚡

Step 1: Preparing the crispy base 🥧

Lightly grease two 11.5cm fluted tartlet tins. Place the dough sheets, cover each other and roll them out to a thickness of 3 mm. Place the dough in the molds, trim the excess, and cover them with baking paper and weights or rice. Cook in the air fryer at 200°C for 6 minutes, remove the paper and legumes and bake for 2 more minutes. The result: a crispy, golden base, ready for the filling.

Step 2: Caramelizing the onion 🧅✨

Heat the oil in a frying pan over medium heat. Add the onion and cook, stirring occasionally, for 10 minutes or until golden and caramelized. This step is key: the caramelized onion provides that deep sweetness that makes these cakes addictive. Let it cool a little before adding it to the filling.

Step 3: Mixing the creamy filling 🥚🧀

In a bowl, combine the cream cheese, sour cream, cheddar cheese and one egg. Add the caramelized onion and mix well. Season with salt and pepper. Divide the mixture between the tart shells, leaving a small well in the center for an additional egg if you want an extra gourmet touch.

Step 4: Final cooking in air fryer 🔥

Place the pies in the air fryer at 170°C for 10–12 minutes, or until the egg and filling are cooked to your liking. Let cool in the fryer for 5 minutes. Before serving, sprinkle with fresh chopped chives for a touch of color and freshness. 🌿

Tricks to take your cakes to the next level 🧑‍🍳✨

Vary the cheeses: Combine Gruyère or Gouda with Cheddar for a more intense flavor.
Add fresh herbs: Thyme or rosemary before baking give an irresistible aroma.
Use XXL fryer: allows you to bake both cakes at the same time without losing texture.
Customize the egg: You can leave the yolk liquid for a “natural sauce” effect on the cake. 🥚💛
