How Long To Cook 2 Briskets In The Oven

by

Cooking two briskets together in the oven means accounting for moisture loss and extended time since they share the same heat. So how long to cook 2 briskets in the oven? Plan for about 1.25 to 1.5 hours per pound total, but since you have two pieces of meat, expect the cook to run longer than a single brisket of the same combined weight.

Most home cooks find that two 10-pound briskets take anywhere from 12 to 16 hours at 225°F. The exact time depends on your oven, the size of each brisket, and how often you open the door.

How Long To Cook 2 Briskets In The Oven

The short answer is 1.25 to 1.5 hours per pound per brisket, not per total weight. Two 8-pound briskets are not the same as one 16-pound brisket. Each piece of meat cooks on its own schedule, and two pieces in the same oven slow things down a bit.

Here is a simple time chart to help you plan.

  • Two 5-pound briskets at 225°F: 7 to 9 hours
  • Two 8-pound briskets at 225°F: 11 to 13 hours
  • Two 10-pound briskets at 225°F: 13 to 16 hours
  • Two 12-pound briskets at 225°F: 15 to 18 hours

Add one to two hours of rest time before slicing. A long rest in a cooler or warm oven makes the meat more tender and easier to slice.

Why Two Briskets Take Longer Than One

Two briskets release more moisture into the oven. That moisture slows the cook and lowers the oven temp each time you open the door. The meat also blocks airflow, so heat moves around the oven less evenly.

You also have twice the mass to bring up to temperature. The oven has to work harder to hold steady heat, especially in the first few hours.

Pick The Right Size Briskets

Try to buy two briskets that are close in weight. If one is 6 pounds and the other is 12 pounds, the smaller one will finish hours before the larger one. That makes timing hard.

  • Aim for two briskets within 1 to 2 pounds of each other
  • Trim both to about 1/4 inch of fat on top
  • Keep the point and flat together if you can

Set Up Your Oven And Pan

Use a large roasting pan with a rack. The rack keeps the meat out of the drippings, which helps the bark stay firm. Line the pan with foil for easier cleanup.

  1. Preheat the oven to 225°F. Some cooks go to 250°F to save time, but 225°F gives better results.
  2. Place the rack inside the pan.
  3. Set both briskets fat side up on the rack. Leave at least 1 inch between them.
  4. Add 1 cup of water or beef broth to the bottom of the pan. This keeps the oven humid.
  5. Cover the pan tightly with foil, or leave it open if you want a darker bark.

Season And Prep Both Briskets

Pat each brisket dry with paper towels. A dry surface helps the rub stick and helps the bark form. Use a simple rub of salt, black pepper, garlic powder, and onion powder.

Apply the rub to both sides of each brisket. Let them sit at room temperature for 30 minutes before they go in the oven. This takes the chill off and helps them cook more evenly.

Monitor The Cook Time

Do not rely on time alone. Use a meat thermometer. Insert it into the thickest part of the flat, away from fat and bone.

  • 160°F to 170°F: The stall. This is normal. The temp may sit here for hours.
  • 195°F to 205°F: Done. The probe should slide in with little resistance.
  • Check both briskets. One may finish 30 to 60 minutes before the other.

If one brisket hits 203°F early, pull it out and wrap it in foil and a towel. Put it in a cooler. It will stay hot for 2 to 3 hours.

Wrap Or Not Wrap

Wrapping in foil or butcher paper speeds up the cook and keeps moisture in. The trade-off is a softer bark. Many cooks wrap at the stall, around 165°F.

If you want a firm bark, leave both briskets unwrapped the whole time. Just know the cook will run longer and the meat may dry out a bit on the edges.

Resting And Slicing Two Briskets

Rest each brisket for at least 30 minutes. An hour is better. Resting lets the juices settle so they do not run out when you slice.

  1. Wrap each brisket in foil or butcher paper.
  2. Place them in a dry cooler with a towel on the bottom and top.
  3. Close the lid and let them rest for 1 to 2 hours.
  4. Slice against the grain. The flat slices thin, the point slices thicker.

Common Mistakes To Avoid

  • Cooking by time only. Always use a thermometer.
  • Cramming both briskets so they touch. Air needs to move around them.
  • Opening the oven too often. Each peek drops the temp and adds time.
  • Skipping the rest. Slicing too soon loses juice and makes the meat tough.
  • Using a pan that is too small. The meat should fit with room to spare.

Quick Tips For A Better Cook

Put the larger brisket on the lower rack and the smaller one above it. Heat rises, so the top one cooks a bit faster. Rotate the pans halfway through if your oven has hot spots.

Keep a log of your cook times and temps. After two or three tries, you will know exactly how your oven behaves with two briskets inside.

If you are short on time, you can cook two briskets at 275°F. That cuts the time to about 1 hour per pound. The meat will still be tender, but the bark may be a little softer.

Plan for a long cook, keep the oven closed, and trust your thermometer. Two briskets is a big job, but with the right timing, both will come out tender and ready to serve.
