Chop the potatoes into 2 in chunks and roughly chop the onion.
Add the potatoes, onion, chicken broth, garlic, salt, and pepper to the crock pot and cook on high for 4 hours or low for 6-8 hours.
Once it is done cooking open the lid and add the cream cheese, cheddar cheese, and cream. Use a potato masher to blend the soup together for a very slightly chunky loaded potato soup, or an immersion blender for a super smooth loaded potato soup.
Top with your choice of toppings and Enjoy!
