How Long Will a 13 LB Brisket Take at 225 Degrees?

Are you planning to cook a 13 lb brisket and wondering how long it will take to cook at 225 degrees? Slow cooking brisket requires patience and precision to achieve a tender and flavorful result, but the time it takes can vary depending on several factors. Let’s take a closer look at cooking time, slow cooking, and the ideal cooking temperature for a mouthwatering brisket.


Understanding Brisket and its Cooking Process

Smoking a brisket is one of the most rewarding culinary experiences out there. Not only is it delicious and comforting, but it’s also a labor of love that requires patience and skill. In this section, I’ll explain what brisket is, the process behind smoking it, and share a mouthwatering smoked brisket recipe.

What is Brisket?

Brisket is a cut of meat that comes from the lower chest of a cow. It’s a tough piece of meat due to the high amount of connective tissue it contains, but when cooked low and slow, the tissue breaks down, resulting in a tender and flavorful dish. Brisket is commonly used in barbecue and is a staple in Texas-style barbecue.

The Smoking Process

Smoking brisket involves cooking it with indirect heat over a period of several hours. The goal is to break down the tough connective tissues while infusing the meat with a smoky flavor. For best results, a smoker is the ideal tool, but if you don’t have one, you can use a charcoal grill with wood chips or a gas grill with a smoking box. The key is to maintain a consistent temperature over a long period of time, usually between 225-250 degrees Fahrenheit, depending on the recipe.

Smoked Brisket Recipe

Here’s my tried-and-true smoked brisket recipe:


  • 1 10-12 lb whole packer brisket
  • 1/4 cup kosher salt
  • 1/4 cup black pepper
  • 1/4 cup paprika
  • 1/4 cup brown sugar
  • 1/4 cup garlic powder
  • 1/4 cup onion powder


  1. Preheat the smoker to 225 degrees Fahrenheit.
  2. Combine all the dry rub ingredients in a bowl.
  3. Trim off any excess fat from the brisket.
  4. Rub the dry rub liberally all over the brisket.
  5. Place the brisket in the smoker, fat side up.
  6. Smoke the brisket until it reaches an internal temperature of 165 degrees Fahrenheit.
  7. Wrap the brisket tightly with butcher paper or aluminum foil and return it to the smoker.
  8. Continue cooking the brisket until it reaches an internal temperature of 195-203 degrees Fahrenheit.
  9. Remove the brisket from the smoker and let it rest for at least 30 minutes before slicing and serving.

Brisket Smoking Time

The smoking time for brisket can vary depending on several factors, including the size and thickness of the meat, the type of smoker, and the cooking temperature. As a rule of thumb, a 10-12 lb brisket can take anywhere from 10-15 hours to smoke at 225 degrees Fahrenheit. It’s important to use a meat thermometer to monitor the internal temperature of the brisket and ensure it’s cooked to the desired level of doneness.

Now that you have a better understanding of brisket and the smoking process, it’s time to fire up the smoker and get cooking! With this delicious recipe and smoking tips, you’ll be sure to impress your friends and family with a mouthwatering smoked brisket.

Factors Affecting Brisket Cooking Time

Brisket is a challenging cut of meat to cook, and the cooking time can vary depending on several factors. The size and weight of the brisket will impact the cooking time, as well as the cooking method and temperature. Different cuts of brisket might have different cooking times as well.

Cooking a brisket at 225 degrees requires patience, and it is essential to monitor the internal temperature of the meat regularly. The general rule of thumb is to cook a brisket for one hour and 15 minutes per pound of meat at this temperature. However, other factors can impact the cooking time, such as:

  • The thickness and uniformity of the meat
  • The presence of a fat cap on the brisket
  • The environment and equipment used for cooking
  • The desired level of doneness (rare, medium-rare, medium, well-done)

For example, a brisket with a thicker fat cap might require a longer cooking time to render the fat and achieve a tender result. Similarly, a fluctuating cooking temperature can extend the cooking time needed to reach your desired doneness.

When cooking a brisket at 225 degrees, it is best to plan for a cooking time of 8 to 12 hours for a 13 lb brisket. However, it is always recommended to use a meat thermometer to check the internal temperature and ensure the meat reaches an internal temperature of 195 to 205 degrees Fahrenheit for a tender and juicy brisket.

Recommended Cooking Time for a 13 LB Brisket at 225 Degrees

After years of smoking briskets, I have found that a 13 lb brisket takes anywhere from 8 to 12 hours to cook at a temperature of 225 degrees. This is just an estimated range, as various factors can affect the actual cooking time.

One important factor to consider is the type and quality of your smoker. Different smokers have different heating patterns, which can affect your brisket’s cook time. Additionally, the thickness and consistency of the brisket can impact how long it takes to cook. Always monitor the internal temperature of your brisket with a meat thermometer to ensure it reaches an internal temperature of at least 195 degrees Fahrenheit.

Another consideration is the environment in which you are cooking. Wind and weather conditions can impact how your smoker retains heat and cook your brisket. If it’s a particularly windy day, for example, your smoker may need to work harder to maintain the desired temperature, which can add to the overall cook time.

Finally, keep in mind that each brisket is unique, and even with all the factors accounted for, it may still take longer or shorter to cook than anticipated. So be patient and trust the process, and remember to always let your brisket rest for at least 30 minutes before slicing into it.

With these factors in mind, you can plan accordingly and prepare a delicious, mouthwatering brisket for your next gathering.

Tips for Perfectly Cooked Brisket

When it comes to cooking brisket, slow and steady wins the race. Slow cooking a brisket allows the meat to break down and become tender, resulting in a melt-in-your-mouth texture.

Here are some tips to achieve the perfect brisket:

  • Seasoning: Be generous with your seasoning, using a combination of salt, pepper, and other spices that complement the beef.
  • Trimming: Trim off any excess fat before cooking to prevent a greasy taste and texture.
  • Wrapping: Consider wrapping the brisket with foil or butcher paper during the cooking process to keep the meat moist and prevent it from drying out.
  • Basting: Basting the brisket with its own juices or a flavorful marinade can add extra moisture and flavor.
  • Temperature: Keep a consistent temperature throughout the cooking process, aiming for around 225 degrees Fahrenheit.
  • Patience: Allow enough time for the brisket to cook thoroughly, usually around 1 hour per pound. Resist the temptation to rush the process!

By following these tips and techniques, you can create a delicious brisket that is sure to impress your guests. Remember, slow and steady wins the brisket race!

Tips for Perfectly Cooked Brisket

Slow cooking a brisket is all about patience and attention to detail. Here are some tips and techniques to ensure your brisket comes out tender and flavorful:

  • Season generously: Brisket is a massive piece of meat that requires a lot of seasoning to bring out the best flavors. Make sure to rub the brisket with a well-balanced seasoning blend before cooking.
  • Wrap the brisket: After a few hours of cooking, wrap the brisket tightly in foil or butcher paper to keep the moisture in and prevent it from getting too dry.
  • Use a meat thermometer: The only way to know if the brisket is done is by measuring its internal temperature. Insert a meat thermometer into the thickest part of the meat, and it should read between 195-205 degrees Fahrenheit when it’s ready.
  • Let it rest: Once the brisket is done, remove it from the heat and let it rest for at least 30 minutes. This allows the juices to redistribute throughout the meat, making it juicier and more flavorful.
  • Slice against the grain: To ensure maximum tenderness, always slice the brisket against the grain. This means cutting perpendicular to the long lines of muscle fibers.

By following these tips, you’ll be able to create a mouthwatering brisket that will impress all your guests.

TIP: If you’re short on time, consider wrapping the brisket in foil and finishing it in the oven. This will help to speed up the cooking process and ensure that it’s cooked to perfection.
