Crock Pot Stuffing

My mother-in-law makes this every year for Thanksgiving and it is FANTASTIC!! This year it is MY turn!!
I hope mine turns out as well as hers does! Happy Thanksgiving everyone!!

1 cup butter
2 cups onion,chopped
2 cups celery, chopped
1/4 cup fresh parsley sprigs, chopped
12-13 cups bread crumbs (or two 7 oz. bags of packaged bread cubes for stuffing, try half white bread, half cornbread if you like)
1 tsp. poultry seasoning
1 1/2 tsp. sage
1 tsp. thyme
1/2 tsp. black pepper
2-2 1/2 cups chicken broth, added a little at time AS NEEDED until moist. If using packaged bread crumbs you may need to increase broth to 3-3 1/2 cups. BE CAREFUL not to add too much or you will end up with stuffing soup....
2 eggs, beaten slightly

Melt butter in saucepan. Saute onion, celery and parsley in butter until tender. Pour over bread crumbs in crockpot. Add seasonings and eggs, and moisten with broth as needed. Mix well.

Place crockpot on high for 45 minutes, then turn to LOW for 4-8 hrs.

If you like mushrooms you can add a small can of mushrooms. The original recipe also list 1 tsp. marjoram, but that is optional.
