Cod au gratin with "all i oli" (garlic mayonnaise)

Cut the onion into julienne strips and fry in oil over medium heat until soft. Set aside

We make the "all i oli". Grind the fresh cheese, the boiled eggs, a squeeze of lemon, the garlic and a spoonful of olive oil, until you get the consistency without lumps.

Put the desalted cod in a dish (you can use hake or fresh cod). On top of the onion and the "all i oli" and a little grated cheese, if you want.

We put it in the oven or Air fryer for 15 minutes at 150 degrees, or until it is au gratin. Delicious!!! 😋
