In a medium saucepan, cook potatoes in boiling water until tender (8-10 minutes). Strain and place in an ungreased 2.5 quart (2.3 L) casserole dish
Combine chicken thighs, breast, and celery in the casserole dish
In a medium sized frying pan, saute mushrooms, carrots, and onion until tender
Add celery seed, onion soup mix, and salt, then add to casserole dish
Place cream of mushroom soup in the casserole dish
Prepare biscuits. Arrange completed biscuits on top of casserole
Bake uncovered for 30 minutes until the biscuits are golden
Notes
If you don’t have the time to prepare the soup from scratch but are looking for a dairy free alternative, 2 packets of Roux Onion Gravy would work well too
