Heat the sous vide water bath to 145℉ degrees for a sliced roast finish. 165℉ for a pulled pork finish.
Sprinkle seasonings all over the pork roast.
Seal the pork roast in your vacuum sealer (or use a high quality zip top freezer bag) using the moist seal setting.
Place the pork roast into the water bath and cook for 18 to 24 hours.
Remove the pork from the water bath, open the bag and allow it to rest while heating the oven broiler.
Reverse sear the pork roast by carefully, placing in a broiler-safe pan such as an iron skillet and brown each side. Achieving a brown crust will only take 45-60 seconds per side.
