Morel Pie

I know that one of the ingredients (morel mushrooms) for this recipe won't be available for many of you, but since I had never heard of a morel pie and this recipe was published in today's Peoria Journal-Star, I thought some of you might find it interesting.  They said it was adapted from a recipe of Chef Michael Higgins of Maldaner's Restaurant in Springfield (IL).  Since I am personally not a morel hunter, I have not tried this recipe.
 
1 pre-baked pie shell
Dijon mustard
1/4 lb. butter
1 sweet onion (Vadalia preferred), julienned
1/2 lb. morel mushrooms (from the accompanying picture, probably coarsely chopped)
1/2 tsp. thyme
1 cup grated Parmegiano
2 cups cream (not half & half)
2 eggs, lightly beaten
salt & pepper, to taste
1 cup cracker crumbs
 
- Brush pre-baked pie shell with Dijon mustard and sprinkle with some of the grated cheese.  Heat in the oven at 350 degrees until the cheese melts.
- Saute onions in butter until soft.  Add morels and cook until they are soft and half of the juice has reduced.
- Add thyme, cream and remaining cheese.  Simmer; then add the beaten eggs.  Add salt and pepper to taste.
- Pour mixture into pie shell.  Sprinkle cracker crumbs on top.
- Bake at 350 degrees until top is brown and custard is set.  Cool before cutting.
