Ingredient Notes
Pork Tenderloin
This cut is lean, mild, and naturally tender. It cooks beautifully in the slow cooker. Be sure not to confuse it with pork loin, which is larger and requires a longer cooking time.
Silver Skin
Trim away the thin silvery membrane before cooking, as it stays tough even after hours of slow cooking.
Onion Soup Mix
A packet of dry onion soup mix adds instant savory flavor thanks to dehydrated onions and seasonings.
Cream of Mushroom Soup
This creates the creamy base for the gravy. Regular versions tend to provide the richest flavor and texture.

3. Pour Over the Pork
