Oven Brisket Cook Time: How Long to Cook Brisket in the Oven (Complete Guide)

How long to cook brisket in the oven? The answer depends on weight and temperature, but generally it takes 1 hour per pound at 275°F (135°C) until internal temperature reaches 195-205°F (90-96°C). This low-and-slow method ensures tender, juicy results. Let's break down exactly what you need to know.

Weight of Brisket	Estimated Oven Time (at 275°F)	Internal Temp Goal
3–4 lbs	3–4 hours	195–205°F
5–6 lbs	5–6 hours	195–205°F
7–8 lbs	7–8 hours	195–205°F

Always use a meat thermometer to verify doneness. Time estimates vary based on oven calibration, brisket thickness, and fat content. Never rely solely on time — internal temperature is the only reliable indicator.

The Texas Crutch Method

When the brisket hits the "stall" (150-170°F internal temperature), wrap it tightly in foil or butcher paper. This traps steam, speeds up cooking by 30-50%, and prevents drying. Continue cooking until it reaches 195-205°F.

How to Know When Brisket is Done

Brisket is perfectly cooked when:

• Internal temperature reaches 195-205°F (90-96°C)
• A meat thermometer or skewer slides in with almost no resistance ("probe test")
• Meat feels like soft butter when pressed

Undercooked brisket will be tough and chewy; overcooked becomes dry. Always check both temperature and texture.

Common Mistakes That Extend Cook Time

• Incorrect oven temperature: Use an oven thermometer to verify accuracy. A 25°F difference can add 1-2 hours to cooking time.
• Skipping the Texas Crutch: Unwrapped brisket stalls longer at 150-170°F, extending total cook time by hours.
• Higher cooking temperatures: Cooking above 300°F dries out meat and prevents collagen breakdown, resulting in tough brisket despite reaching temperature.
• No resting period: Cutting too soon causes juice loss. Always rest 1-2 hours before slicing.

Simple Dry Rub Basics

While dry rubs don't affect cook time, they enhance flavor. Apply a basic rub (salt, black pepper, paprika) 1 hour before cooking for best results. Avoid excessive sugar which can burn during long cooking.

Essential Tools for Success

• Meat Thermometer: Wireless probe thermometers (like Weber Smokey Touch) allow remote monitoring without opening the oven.
• Heavy-Duty Foil or Butcher Paper: Critical for the Texas Crutch method to maintain moisture.

Frequently Asked Questions

How long does it take to cook brisket in the oven?

Brisket typically cooks at 275°F for about 1 hour per pound. A 3-4 lb brisket takes 3-4 hours, 5-6 lb takes 5-6 hours, and 7-8 lb takes 7-8 hours. However, always rely on internal temperature (195-205°F) rather than time alone to determine doneness.

What temperature should I cook brisket at in the oven?

The ideal temperature for oven brisket is 275°F. This low-and-slow method allows tough connective tissues to break down properly without drying out the meat. Some recipes use 225°F for even slower cooking, but 275°F is a good balance of time and quality results for home cooks.

How do I know when my oven brisket is done?

Brisket is done when it reaches an internal temperature of 195-205°F AND passes the "probe test" — when a thermometer or skewer slides in and out with almost no resistance. The meat should feel like soft butter when pressed. Don't rely solely on time or temperature; texture is equally important.

Should I wrap my brisket in foil while cooking in the oven?

Yes, using the Texas Crutch method (wrapping in foil or butcher paper) halfway through cooking can help push through the "stall" period and keep the brisket moist. Wrap when the internal temperature reaches 150-160°F, then continue cooking until it reaches 195-205°F.

Why is my brisket taking longer than expected to cook?

Several factors can affect cooking time: oven temperature accuracy, brisket thickness, fat content, and whether you're using a water pan. The "stall" (when evaporation cools the meat) typically happens around 150-170°F and can last hours. Always use a thermometer rather than relying solely on time estimates.

Can I cook brisket at a higher temperature to save time?

While you can cook brisket at higher temperatures (up to 325°F), this risks drying out the meat and preventing proper collagen breakdown. The low-and-slow method is essential for tender results. Rushing the process usually leads to tough, chewy brisket despite being "done" by temperature.

How long should I rest brisket after oven cooking?

Rest your brisket for at least 1 hour, preferably 1.5-2 hours, tented with foil and wrapped in a towel. This allows the juices to redistribute throughout the meat. Resting in a cooler (without ice) can maintain warmth while resting. Never skip the resting step — it's crucial for juicy results.

Conclusion: Perfect Oven Brisket Every Time

Mastering oven brisket cook time isn't about memorizing exact hours — it's about understanding the science behind the process. Focus on internal temperature, use the Texas Crutch to overcome stalls, and never skip the resting period. With these fundamentals, you'll consistently achieve melt-in-your-mouth brisket that impresses every time.
