Outstanding! Very delicious and hearty! Love the combo of leeks and fresh tarragon. I cut the recipe in half and baked it in a 8 x 8 dish, and it worked fine. I used havarti, as written, but would like to try it with Gruyere also.
Chosen for ZWT game, we enjoyed this for a weekend Sunday brunch, I made this using provolone cheese, and that worked very well, If you love onions, this is a must-try! so good Parsley! thanks for sharing!...Kitten:)
