Beef brisket is an inexpensive cut of meat that features a lot of connective tissue. It can be cooked in a variety of ways, but most methods emphasize the “low and slow” approach that results in the connective tissue breaking down so that you’ll end up with a tender and flavorful piece of meat. Some recipes call for spice rubs and others for barbecue sauce, but one of the easiest and most foolproof recipes uses an oven cooking bag.

Things You'll Need

Choose the perfect brisket. If the packaging permits, pick up the brisket and try to fold it. If it will not give, put it back. Find one that will fold the most; the ease of folding indicates that the brisket doesn’t have too much fat on it. Also, check the color — the redder, the better.

Take your brisket out of the package and trim most, not all, of the fat from it. Some fat is necessary to provide flavor.

Open one package of the onion soup mix. In a small bowl, add one cup of water to the soup mix and mix well. If you have a large brisket, you may wish to use two packets of soup mix and two cups of water. Don’t worry about having too much; you can’t overdo it as long as it fits into the oven bag with the brisket.

Prepare your oven bag by opening it and inserting the brisket.

Pour in the onion soup mix, fasten the tie that was included in the package with the cooking bag and massage the mixture into the meat. Flip it over several times. Set it in the refrigerator for a few hours to marinate, turning it once in a while. If the bag tears, just slip the second bag over the whole thing and tie it.

Preheat oven to 250 degrees Fahrenheit. Place bagged brisket into your pan with the fat side up. Put it into the oven. Cook five to eight hours. Take it out and let it cool. Remove from the bag and slice it; it may be so tender it just falls apart.


  • Find something to do while you are cooking; don’t keep checking the brisket.

  • You can add any vegetables you like before closing the bag; carrots, onions and celery will add to the flavor. You could also prepare mashed potatoes to accompany your meal.
