1-Getting started: Getting started with this slow cooker beef broccoli recipe is straightforward and rewarding. Begin by preparing your ingredients, like slicing the beef chuck roast into thin strips, as this helps it cook evenly and absorb flavors. Once ready, whisk together the sauce in a bowl to ensure it’s well mixed before adding it to your slow cooker.

2-Slow cooking: Place the beef strips into a 4-7-quart slow cooker and pour the sauce over them, coating everything thoroughly. Set the cooker to low and let it work its magic for 2.5 to 3.5 hours, allowing the beef to become incredibly tender. About one hour before the cooking ends, remove ¼ cup of the sauce, mix it with 2 tablespoons of cornstarch, and stir it back in to thicken things up nicely.

3-Final touches: In the final 30 minutes, add the frozen broccoli florets and stir gently. This step keeps the broccoli crisp-tender, adding a fresh contrast to the soft beef. Once done, serve your dish with white rice and garnish with green onions and sesame seeds for an extra touch of flavor. Preparation takes about 20 minutes, and the total cooking time is around 3 hours and 20 minutes, making it ideal for weeknights.
