Ingredients

Scale

Beef

  • lb flank steak, sliced into ¼ inch pieces against the grain
  • ¼ cup cornstarch

Sauce & Seasoning

  • 1½ tablespoons sesame oil
  • 2 teaspoons garlic, minced
  • ½ teaspoon fresh ginger, minced
  • 2 teaspoons rice vinegar
  • ½ cup soy sauce
  • ½ cup beef broth
  • ¾ cup brown sugar
  • ¼ teaspoon red pepper flakes

Instructions

  1. Coat the Beef: Place the sliced flank steak and cornstarch into a Ziplock bag. Seal and shake vigorously until all the steak pieces are evenly coated with cornstarch. This helps create a slightly thickened texture in the sauce during cooking. Transfer the coated beef to the bottom of a 6-quart crock pot.
  2. Prepare the Sauce: In a medium bowl, combine the sesame oil, minced garlic, minced fresh ginger, rice vinegar, soy sauce, beef broth, brown sugar, and red pepper flakes. Whisk the ingredients thoroughly until the brown sugar has dissolved and the mixture is well blended.
  3. Cook the Beef: Pour the prepared sauce evenly over the coated flank steak in the crock pot. Cover the crock pot with its lid and set it to cook on high heat for 2 to 3 hours, or alternatively, on low heat for 4 to 5 hours. The beef will become tender and absorb the rich sauce during this slow cooking process.
  4. Serve: Once the beef is fully cooked and tender, serve it hot over steamed white or brown rice. Garnish with finely chopped green onions or scallions to add a fresh, vibrant touch to the dish.

Notes

  • For best texture, slice the flank steak thinly across the grain before coating with cornstarch.
  • Adjust red pepper flakes to taste for more or less heat.
  • If you prefer a thicker sauce, you can remove the beef when done and simmer the liquid on the stovetop to reduce.
  • Garnish with sesame seeds and chopped green onions for additional flavor and presentation.
  • Use low sodium soy sauce if you want to control the salt level in the dish.
