Yes, you can sous vide meat directly from frozen, but you'll need to increase the cooking time by approximately 50% to ensure it reaches the desired internal temperature.
Sous vide cooking relies on precise temperature control, and starting with frozen meat simply means it will take longer to reach that temperature. The frozen state acts as a buffer, slowing down the heat transfer. To compensate, you need to extend the cooking time. A general rule of thumb is to add about 50% to the recommended cooking time for thawed meat. For example, if a steak would normally take 1 hour to cook sous vide, it would take 1.5 hours from frozen. It's crucial to use a reliable sous vide time and temperature guide that accounts for the thickness and type of meat you're cooking. Always verify the internal temperature with a food thermometer to ensure it has reached a safe and palatable level. Remember that thicker cuts will require a longer adjustment period.
When cooking from frozen, consider searing the meat immediately after the sous vide process. The rapid temperature change from the hot pan to the already cooked interior helps to create a beautiful crust without overcooking the inside.
