Creating Slow Cooker Beef and Broccoli is straightforward when you follow these simple steps:

1. Prep the Vegetables: Wash and cut the broccoli into bite-sized florets.
2. Prepare the Beef: Thinly slice the flank steak against the grain for tenderness.
3. Mix the Sauce: In a medium bowl, whisk together beef broth, soy sauce, brown sugar, ginger, garlic, and sesame oil until combined.
4. Combine in Slow Cooker: Place the sliced beef in the slow cooker. Pour the sauce over the beef and stir to combine.
5. Cook on Low: Cover and cook on low for 4-6 hours or on high for 2-3 hours. The beef should be tender when done.
6. Add Broccoli: About 30 minutes before serving, add the broccoli florets to the slow cooker. Stir gently to incorporate.
7. Thicken the Sauce: In a small bowl, mix cornstarch and water to create a slurry. Stir this into the slow cooker during the last 10 minutes to thicken the sauce.
8. Serve: Once everything is cooked, serve over cooked rice and garnish with sesame seeds if desired.

By following these steps, your Slow Cooker Beef and Broccoli will turn out perfectly every time, bursting with flavors and textures that families love.
