Here’s another Provençal omelet, this one topped with a mix of caramelized golden onions, cooked slowly in a cazuela with milk and blue cheese. You can make the topping in advance.
Ingredients
1 large onion, quartered lengthwise and thinly sliced
Put the onion, 2tablespoons of the butter, the salt, and the sugar in the cazuela set over low heat. Cover and steam the onion for 45 minutes, until very soft. Season with the pepper.
Uncover, raise the heat to medium, and cook, stirring, until golden brown, 10 to
