Follow these simple steps to prepare your Slow Cooker Beef and Broccoli:

1. Prepare the Sauce
   In a bowl, mix together the beef broth, soy sauce, dark brown sugar, sesame oil, and minced garlic. This will be the flavorful sauce that coats your beef and broccoli.
2. Combine Beef and Sauce in the Slow Cooker
   Place the beef strips in the slow cooker and pour the sauce over them. Toss to ensure that the beef is evenly coated with the delicious mixture.
3. Start Cooking
   Set your slow cooker to low and cook for about 5-6 hours. It’s a good idea to check at the 5-hour mark to make sure the beef does not overcook.
4. Thicken the Sauce
   About 1 hour before the cooking time is up, take ¼ cup of the sauce from the slow cooker and mix it with the cornstarch in a small bowl. Stir this mixture back into the slow cooker to thicken the sauce.
5. Add the Broccoli
   Add the frozen broccoli florets during the last 30 minutes of cooking. This will ensure that the broccoli remains bright and crisp, adding a delightful texture to the dish.
6. Serve and Enjoy
   Serve the beef and broccoli over a bed of white rice for a complete and satisfying meal. Enjoy the blend of flavors and textures in every bite!
