Step 1

Add beef and onion portions to a slow cooker. In a mixing bowl whisk together beef broth, soy sauce, sesame oil, brown sugar and garlic. Season mixture with salt and pepper to taste.

Step 2

Pour mixture over beef and onions in slow cooker. Cover with lid and cook on low heat 2 1/2 - 3 1/2 hours, until meat has cooked through.

Step 3

Ladle out 1/4 cup of the broth from slow cooker and pour into a bowl. Add cornstarch and whisk until smooth then return broth mixture to slow cooker and gently stir.

Step 4

Add in broccoli pieces (if you want vibrantly green broccoli you can steam it instead then add it at the end) and cover slow cooker with lid, then increase to high heat and cook 20 minutes longer, or until broccoli is tender and sauce has thickened slightly.

Step 5

Remove onion pieces. Serve warm over white or brown rice sprinkled with optional sesame seeds.
