Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Once cool, dice.
Peel and chop potatoes and onion.
Place potatoes into a 4-qt slow cooker. Stir in chicken stock, onion, Salt of the Gods, Steak & Bake, butter and bacon until well combined.
Cover and cook on low heat for 7-8 hours or high heat for 3-4 hours, or until potatoes are tender.
Using a potato masher, mash potatoes until desired consistency is reached. Stir in cheese, sour cream and heavy cream until smooth; season with Salt of the Gods, to taste.
Cover and cook on low heat until warmed through, stirring occasionally, about 15-20 minutes. If the mixture is too thick, add more chicken stock as needed until desired consistency is reached.
Serve immediately. Make it your own by adding more bacon, green onion and cheese on top!
