Chuck Roast (Pot Roast)
Chuck Roast (Pot Roast)
cooking times
3 hr 30 min – 4 hr 5 min At the most common temperature, 300°F, a chuck roast runs about 3 hr 30 min – 4 hr 5 min at 3.5 lb. Pick your temperature below for the full chart. Done is always 145°F internal.
When is it actually done?
145°F internal The USDA FSIS safe minimum internal temperature for this cut is 145°F, followed by a rest of about 15 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.
Pull temperature vs safe temperature: 145°F makes chuck safe but tough. Pot roast is cooked far past it — to roughly 195–205°F — because that is where the collagen dissolves and the meat shreds. With chuck, 'done' means tender, not merely safe.
Worth knowing before you start
- These times assume a covered pot with braising liquid — the traditional pot roast. Dry-roasted chuck at these temperatures will not tenderise the same way.
- The stall is real: the internal temperature can sit in the 150s–160s for an hour while moisture evaporates. It is physics, not a broken thermometer.
- Fork-tender is the finish line — if the fork twists out cleanly, it is done regardless of what the clock says.
- It is very hard to overcook a braised chuck roast and very easy to undercook one. When in doubt, another 30 minutes.
