vibrant veggies and sliced brisket in meal prep container


  • 7 lb. brisket flat
  • 1/4 cup salt
  • 1/4 cup pepper
  • Yellow mustard (as a binder)

Special Tools


  1. Remove the brisket flat from the packaging and immediately start trimming any gray, hard, and excess fatty areas. There usually isn’t much to trim on brisket flats, but you want a consistent thickness to get an even cook.
  1. Combine your salt and pepper in a small bowl. Apply a coat of yellow mustard to the brisket as a binder which will help the salt and pepper stick.
  1. Once the mustard has been applied to one side, sprinkle a light coating of your salt and pepper mix. Pat with your hand to help the seasonings stick. Flip the meat and repeat. The amount of seasoning is up to you.
  1. Let the meat rest at room temperature to get rid of some of the chill. Meanwhile, preheat your Pit Boss smoker to 200°F.
  1. Once your grill is ready, place the brisket on the top rack and an aluminum tray half-way filled with water underneath.
  1. Cook for 10-12 hours - until internal temp is 175°F
  1. Once the internal temperature reaches 175°F, increase the smoker temp to 250°F and cook until the brisket's internal temp reaches 202°F.
  1. Once the temp reaches 202°F, remove and wrap in butcher paper and let it rest for 1 hour.
  1. Slice it up, place it in your meal prep containers along with your favorite sides, and ENJOY!
