The days have still been cool enough to enjoy a good casserole. I had a similar dish to this many years ago made with three onions and three cheeses but I can't remember which kinds. When I saw some nice looking leeks in the store recently, I decided to give this a try. This dish contains two of each (onions and cheese), but the predominant flavours are definitely the leek and Boursin, hence the name of the recipe.
3 large leeks
Aged cheese such as aged cheddar, gruyere or parmesan
1/3 cup Boursin Cheese - pepper or herb flavour
1/2 cup white wine
Slice three large leeks, soak in water, then drain. Slice 2 shallots. Toss shallots and leeks together. Butter a small casserole dish.
Place half of the onion mix in the dish.
Layer with grated parmesan or sliced aged cheddar (I used 3-year old Balderson Cheddar). Sprinkle with freshly ground pepper and salt.
Place the remaining half of the onion mixture on top.
Top with 1/3 cup Boursin Cheese. Add more freshly ground pepper and salt to taste.
Pour white wine over the mixture.
Bake at 350 degrees F for approximately 60 minutes. Top should be browned and onions will be creamy!
