With an oven with sous vide function, you can prepare your meal in a healthy way. You can place your vacuumed food in a steam dish or water bath and heat this at a low, constant temperature. You can easily set the right temperature and the oven ensures that your meal cooks slowly. This way, preparing takes longer but your dish won't become chewy or overcooked. Because the food is in a vacuum bag, moisture doesn't escape and your meat or fish doesn't get dry. The flavor of the marinade also gets absorbed by your food even better.
