Brisket Cooking Time Calculator
Enter your brisket's weight and cooking method to get an estimated total cook time to a 203°F target internal temperature.
How this works
Brisket isn't done at a safe minimum temperature the way a steak is — it needs to reach 195–205°F internally so its tough connective tissue (collagen) has time to break down into gelatin. Low-and-slow smoking at 225°F takes roughly 1 to 1.5 hours per pound; a hotter 325°F oven speeds this up but produces a less classic bark and smoke ring.
Source: Based on widely used barbecue guidance (popularized by pitmasters like Aaron Franklin and outlets such as AmazingRibs.com) of roughly 1 to 1.5 hours per pound at a 225°F smoker temperature, cooked to a 195–205°F internal temperature for tenderness.
Frequently asked questions
What internal temperature should brisket reach?
Most pitmasters target 195–205°F internal, with 203°F a commonly cited sweet spot — well past the 145°F USDA minimum safe temperature for whole cuts of beef, because brisket needs the extra heat and time to become tender.
Why does brisket cook time vary so much between smokers?
Individual smoker temperature swings, brisket thickness and fat content, wind and weather (for outdoor smokers), and whether the brisket is wrapped all affect actual cook time — this calculator gives a planning estimate, not a guarantee, so always cook to temperature, not the clock.
Should I cook brisket by time or by temperature?
By temperature. Use the time estimate here to plan your day (when to start, when guests should arrive), but always pull the brisket based on its internal temperature and probe-tenderness, not a fixed clock time.
