# Ingredient List:

→ Beef

01 - 2 pounds flank steak, thinly sliced against the grain

04 - 1/2 cup hoisin sauce
05 - 4 cloves garlic, minced

# How to Make:

01 - Lightly spray the inside of your slow cooker with nonstick cooking spray to prevent sticking.

03 - In a medium bowl, whisk together soy sauce, brown sugar, hoisin sauce, and minced garlic until the sugar is mostly dissolved.
04 - Pour the sauce mixture over the beef and toss to coat evenly.
05 - Cover and cook on LOW for 4 hours, or until the beef is tender and the sauce is slightly thickened.
06 - Stir well before serving. Serve hot over steamed rice or with steamed vegetables.

# Helpful Tips:

01 -
  • This is the kind of dinner that makes people think you spent all day cooking when really you just threw everything in a pot and walked away
  • The sauce balances sweet and savory so perfectly that my grandmother actually asked for the recipe card after one bite
02 -
  • Removing the lid more than once or twice during cooking adds significant time to your cook, so resist the urge to check on it constantly
  • The sauce will look thin right up until the last hour, but patience pays off as it naturally thickens while the beef releases its juices
03 -
  • A sharp knife is your best friend for slicing flank steak properly, so take the time to hone your blade before starting
  • Letting the beef rest for 5 minutes after cooking gives the juices time to redistribute instead of running out onto your plate
