Preheat the Sous Vide circulator: Add enough water to the sous vide container or a large pot that the meat will be fully submerged; Set the temperature to your desired doneness, I like: 136°F (58°C).
Pre-sear the roast - if you choose to pre sear the roast, see instructions above.
1 3-4 pound (1.81 kg) chuck roast
Add flavoring to the bag - if you are adding additional flavoring add it to the bag.
Place the meat into the sous vide or freezer zip-top bag.
Submerge the bag: using the 'water displacement' technique: close all but one corner of the bag and slowly lower the bag with the roast into the water bath. The pressure of the water will force out the air. close the zip-top bag.
Sous Vide the Chuck Roast: Cook the chuck roast in the sous vide water bath for 24 hours.
Finishing the roast: remove the bag from the water bath and reserve the purge, the liquid in the bag, for making a gravy or adding to sauces.
to keep the mayonnaise from sliding off the roast before hitting the pan, chill the chuck roast in a water bath for about 10 minutes.
1 Tablespoon mayonaise
Remove the roast from the bag. Pat dry the surface thoroughly with paper towels.
Lightly brush a thin coat of mayonnaise over the surface of the meat.
Sear in a screaming hot cast-iron skillet on all sides for 1 minute to get a delicious crust.
