Step by Step Instructions
STEP ONE – Place the sliced flank steak into the slow cooker pot and sprinkle cornstarch on top. Stir to coat the meat evenly.

STEP THREE – In a small bowl, combine the beef broth, soy sauce, brown sugar, Worcestershire sauce, garlic, ginger, salt and pepper. Pour into the slow cooker.
STEP FOUR – Cover with lid and cook on LOW for 6 hours (or HIGH for 3 hours), until the beef is cooked through and tender.

Sandra’s Top Tips
- When slicing the meat, be sure to cut against the grain for the most tender meat. It will shorten the fibers making it easier to chew.
- If you want crispier veggies, you can add them in during the last 1-2 hours of cooking time.
- Change it up by adding sliced zucchini or button mushrooms.
