Yes, sauteing integrates fat to your food. However, it likely does not integrate as much as you would expect. Cook’s illustrated a test where they fried chicken in 3 cups of oil, and then poured almost 3 cups of oil after all the chicken was cooked — which means that little was genuinely absorbed by the chicken itself. As long as you are keeping your oil hot enough — high heat ascertains that the water in your food will boil, evaporate, and keep oil from letting in — your food won’t get really soggy or greasy.
