Step 1

Grease the inside of a slow cooker. Add steak, beef broth, soy sauce, brown sugar, sesame oil, garlic, and chili flakes. Cover and cook on high for 2-3 hours or low 4-5 hours.

Step 2

Minutes before serving, uncover the slow cooker. In a small bowl, whisk corn starch and water until dissolved. Add to slow cooker and stir. Cover and allow to cook another 20-25 minutes.

Step 3

Just before serving, place broccoli in a large tupperware, fill with 1/2 inch of water, and place the lid on in an off-set manner so that the container can vent. Microwave on high for 3 minutes. Drain, stir broccoli into slow cooker, and serve.
