1. Peel and cut the onion into small pieces. Heat olive oil in a pan, add the diced onions and fry on low heat until the onions turn golden brown, about 40 minutes.

2. Allow it to come down to room temperature, put the fried onions, cream cheese, sour cream and lemon zest and lemon juice in a processor and blend well, adding a little salt and pepper to taste.

3. Chop the shallots, add most of them to the dip and sprinkle the rest on top to garnish.
