1 lb bread cubes (I save old dried bread crusts, rolls, cornbread, etc in the freezer for this)
1 stick butter
1 1/2 cup celery ( I don't always have this.)
1 small onion
1/4 tsp poultry seasoning
1/8 tsp sage
1 T parsley
1 1/2 tsp salt
1/8 tsp pepper
3/4 cup milk
Saute chopped celery and onion in butter. Mix with bread and seasonings. Beat egg with milk and mix into bread. Put in greased 9x13 pan. Cover. Bake at 325 for one hour.
This can easily be frozen ahead.
For turkey and filling casserole, add 3 cups cooked chopped turkey and mix well before baking.
Our favorite way to make filling is fry it in a skillet on the stove instead of baking. It only takes about 15 minutes and it is crunchy and "oh, so good!"
