Substitutions
- Beef Substitutions: Flank steak, skirt steak, flat iron steak, or chuck can be used. Slice against the grain and cut into thin strips no more than ½-inch thick for the best texture.
- Sauce Adjustments: For a sweeter sauce, increase the brown sugar to ½ cup. Taste and adjust before adding the cornstarch.
Instructions
Making this recipe is as easy as 1-2-3! Simply layer the beef, whisk together the flavorful sauce, and let your slow cooker do the rest.


Prepare the Beef
Place the thinly sliced sirloin steak into the slow cooker insert.

Make the Sauce
- In a medium bowl, whisk together the beef consommé (or broth), soy sauce, brown sugar, minced garlic, cornstarch, sesame oil, onion powder, and black pepper until the cornstarch is fully dissolved.
- Pour this mixture over the sirloin steak in the slow cooker.

Cook the Beef
Cover with the lid and cook on LOW for 6-8 hours (or HIGH for 3-4 hours), until the beef is fork-tender and easily pulls apart.

Add the Broccoli
- During the last 30 minutes of cooking, add the broccoli florets to the slow cooker and stir them into the sauce.

Cook
- Place the lid back on, increase the temperature to HIGH (if cooking on LOW), and continue cooking until the broccoli is bright green and tender-crisp.

Garnish and Serve
Garnish with sliced green onions and sesame seeds. Serve over cooked white rice, rolls or cauliflower rice. Enjoy!
