In your slow cooker, whisk together 1 cup of beef stock, ¼ cup of soy sauce, ¼ cup of brown sugar, 1 tablespoon of sesame oil, and 4 minced garlic cloves until well combined.

Next, slice 2 pounds of sirloin steak or chuck roast thinly against the grain and add it directly into the sauce. Toss the beef pieces gently to ensure they're fully coated.

Cover the slow cooker and set it to cook on low for about 5 hours.

With 30 minutes left on the timer, prepare a cornstarch slurry by mixing 2 tablespoons of cornstarch with 2 tablespoons of cold water until smooth, and stir this gently into the slow cooker.

Scatter 4 cups of frozen broccoli florets evenly over the beef in the slow cooker and gently stir to incorporate the broccoli.

Once the cooking time is up, serve your Savory Crock Pot Beef and Broccoli hot over a bed of warm cooked rice.
