Make this copycat Outback Steakhouse Potato Soup recipe in one pot and in about 15 minutes. This is one of the easiest versions of the restaurant favorite I have seen.
If using fresh potatoes:
Put 4 cups diced potatoes into a pot and cover them with cold water about an inch over the potatoes. Bring to a boil then reduce heat to a gentle boil for 10-13 minutes or until tender.
Melt butter and bacon grease in a large pot or Dutch oven over medium heat. When the butter melts sprinkle in the flour, salt and pepper and allow to cook for about a minute stirring constantly with a wire whisk.
Add the chicken broth and chicken bouillon powder and whisk constantly over medium-high heat until the flour mixture dissolves. Stir in the milk, potato pieces and mashed potatoes, bring to a boil.
