Equipment

Ingredients

  • 2 tablespoons olive oil
  • 1/2 cup dark brown sugar packed
  • 2 tablespoons chili powder
  • 1 (1 oz) packet ranch seasoning mix
  • 2 teaspoons paprika
  • 1 teaspoon salt plus more to taste
  • 1/4 teaspoon cayenne pepper omit if you don’t like spice
  • 2 pounds flank steak
  • Honey mustard for drizzling, if desired

Instructions

  • Grease a 6 quart crockpot with cooking spray, then pour in olive oil. Set aside.
  • In a medium sized bowl, whisk together brown sugar, chili powder, ranch mix, paprika, salt, and cayenne. This is our spice rub.
  • Rub a few spoonfuls of the spice rub onto the steak to fully coat it.
  • Place steak into the prepared crockpot, then sprinkle on remaining spice rub.
  • Cover and cook on HIGH for 4 hours or LOW for 8 hours.
  • Remove steak from the crockpot and use a sharp knife to slice it into strips against the grain (this will basically shred your steak, but will prevent it from creating long and stringy pieces).
  • Serve as desired - on a bun, in a quesadilla, over mashed potatoes, on top of Mac and cheese, as nachos, etc. with a drizzle of homemade honey mustard sauce, if desired!
