How to make baby onions in the multicooker
If you have bought pre-peeled Borettane onions, cut away the woody base, wash them, and drain well. Otherwise, peel the baby onions, in this case, I recommend buying 600 g.
Pour the oil into the instant pot, add the baby onions, and brown for 2 minutes with the oven or sauté function at 392°F.
Wet the baby onions with vinegar, add salt, sugar, the bay leaf, and mix. Close the pot, reset it and program it with the pressure function for 6 minutes and start cooking.
At the end of cooking, depressurize the multicooker, then remove the lid. Reprogram at 392°F and let the liquid part evaporate and thicken for 2 minutes. Stir gently to avoid breaking the baby onions.
Serve your sweet and sour baby onions.

Quiche with baby onions with the instant pot
Remove the cooking base and set it aside, gather the baby onions in the center of the pot and cover them with a round puff pastry roll. Crimp the pastry at the sides, pushing it towards the baby onions. Poke the pastry and then cover the pot with the oven or air fryer lid, start the lid cooking for 20 minutes at 356°F. At the end of cooking, check that the pastry is nicely golden and let it rest for 5-10 minutes. Then, with the help of a plate, turn the quiche over, arrange the baby onions, and season with thyme and, if desired, feta crumbs. Serve the quiche accompanied by the cooking base.
If you don’t have the oven lid, remove the baby onions, line the bottom with a sheet of parchment paper, place the pastry and crimp it at the edges. Distribute the baby onions and close the pot, leaving the valve open. Start the baking function at 284°F for about 20 minutes. With the help of the parchment paper, slide the quiche onto a plate.
