Place the scooped innards of the potatoes into a medium bowl. Add 2 Tbsp. butter, 1 – 15 oz. jar Francesco Rinaldi Classic Alfredo Pasta Sauce, season with salt and pepper to taste and add garlic and onion powder. Using a hand-held mixer, mix the potato and sauce mixture until smooth, approximately 5 minutes. Add milk slowly as needed to make the potatoes creamier.
