Hello! When it comes to meal prepping and keeping your portions balanced, a standard single serving size of prepared mashed potatoes is typically between 140 and 150 grams. This generally equates to about half a cup to two-thirds of a cup, depending on how dense or airy your mash is.
From a dietary standpoint, 140 grams is the standard reference amount commonly used on nutritional labels. In terms of energy, that portion usually yields around 150 to 180 calories, though this can vary depending on how much butter, milk, or oil you incorporate into your recipe.
If you want to maintain a well-balanced plate, pairing 140 to 150 grams of mashed potatoes with a solid palm-sized portion of lean protein and plenty of non-starchy vegetables is a great approach. I hope this helps you with your meal prep goals!
