Description

This Slow Cooker Flank Steak is a tender, flavorful dish featuring a brown sugar chili powder rub that infuses the meat with a perfect balance of sweet and smoky spices. Perfect for an easy weeknight dinner, this recipe requires less than 10 ingredients and uses a slow cooker for effortless preparation.


Ingredients

Scale

For the Steak and Rub

  • 2 tablespoons olive oil
  • ½ 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
  • ¼ teaspoon cayenne pepper (omit if you don’t like spice)
  • 2 pounds flank steak

For Serving

  • Honey mustard for drizzling, if desired

Instructions

  1. Prepare the Slow Cooker: Grease a 6-quart crockpot with cooking spray, then pour in the olive oil. Set aside to preheat slightly.
  2. Mix the Spice Rub: In a medium bowl, whisk together the dark brown sugar, chili powder, ranch seasoning mix, paprika, salt, and cayenne pepper. This mixture will be used to coat the steak.
  3. Apply the Rub: Rub a few spoonfuls of the spice rub onto the flank steak until it is fully coated with the flavorful mixture.
  4. Place and Season Steak: Place the coated steak into the prepared crockpot and sprinkle the remaining spice rub evenly over the top.
  5. Cook the Steak: Cover the crockpot and cook on HIGH for 4 hours or on LOW for 8 hours, until the steak becomes ultra tender.
  6. Slice the Steak: Remove the steak from the crockpot and use a sharp knife to slice it into strips against the grain. This technique helps avoid long, stringy pieces and gives a shredded texture.
  7. Serve: Serve the sliced steak as desired – on a bun, in quesadillas, over mashed potatoes, atop mac and cheese, or as nachos. Drizzle with honey mustard sauce if preferred for an extra layer of flavor.

Notes

  • Store leftovers in the refrigerator for 3-4 days.
  • Freeze cooked steak for 2-3 months; thaw in the refrigerator before reheating.
  • Reheat gently in a microwave, oven, or on the stovetop to preserve tenderness.
  • Adjust cayenne pepper according to spice tolerance.
  • Slicing against the grain is crucial to keep the steak tender and easy to chew.
