This low calorie recipe for roasted loaded potatoes calls for real bacon! You can choose to use turkey bacon in place of the real bacon, but I use such a small amount it’s ok. Plus the flavor is so unbeatable.
To cut calories in this baked potato dish, I swapped high calorie, high fat sour cream for Greek Yogurt. When mixed into this loaded roasted potatoes recipe you can’t taste the difference, plus the Greek Yogurt adds a boost of protein.
