Mix all ingredients together in a bowl until well combined. If not using immediately, store in a closed jar in the kitchen cabinet for up to 3 months.
Recipe notes:
How to use the dry rub:
Pat a 2-pound chuck roast dry using paper towels.
Sprinkle the dry rub on a large plate. Press the roast into the dry rub until all of the rub is on the meat.
Transfer the roast into a large resealable plastic bag and refrigerate for 30 minutes.
Heat the oven to 300 degrees F.
Heat oil in a large Dutch oven, then sear the roast in it on both sides.
Add 2 cups chicken broth to the Dutch oven. Bring to a boil, then put on the lid and transfer to the oven. Cook until the meat is fall-apart tender (about 3 hours).
