# How to Make It:

01 - Arrange the sliced steak strips evenly across the bottom of the slow cooker insert.
02 - Scatter the sliced bell peppers, onion, and minced garlic over the beef in an even layer.
03 - In a mixing bowl, whisk together the soy sauce, beef broth, tomato paste, brown sugar, cornstarch, black pepper, and salt until smooth and well combined.
04 - Pour the sauce mixture evenly over the beef and vegetables in the slow cooker.
05 - Cover the slow cooker and cook on low for 6 hours or on high for 3 hours, until the beef is fork-tender and the vegetables are cooked but still retain a slight crunch.
06 - Stir the contents thoroughly, then garnish with sliced green onions and sesame seeds.
07 - Serve hot over steamed rice or noodles.

# Expert Advice:

01 -
  • The sauce thickens into this glossy glaze that coats every strip of beef and makes the house smell incredible for hours.
  • It takes about fifteen minutes of real work and then the slow cooker does everything else while you live your life.
02 -
  • Lifting the slow cooker lid repeatedly lets steam escape and adds thirty minutes of cooking time each time, so keep it closed.
  • The cornstarch must be whisked into cold liquid before going into the cooker or it will clump into unappetizing little balls.
03 -
  • Slice the meat against the grain and at a slight angle so every bite is tender rather than chewy.
  • Use tamari instead of regular soy sauce if you need it to be gluten free, and the flavor stays virtually identical.
