Generously season the steak with black pepper and rub it in. Slice the steak into thin strips and place them in a 6-quart slow cooker with the onion and bell peppers.

In a bowl, mix 1 cup of beef broth with soy sauce, brown sugar, ginger, and garlic powder. Pour this mixture over the steak in the slow cooker.

Whisk the remaining 1/2 cup of beef broth with cornstarch, then pour it into the slow cooker. Stir to combine all the ingredients.

Cover the slow cooker and cook on low for 5 hours. Before serving, taste and adjust seasoning if needed.

Pro Tip: While this recipe offers a Western take on the classic Chinese dish from Fujian province, using beef instead of pork. For an even more authentic experience, try substituting pork for the beef.

With this simple slow cooker recipe, you can bring the delightful flavors of pepper steak to your dinner table, combining the convenience of a home-cooked meal with the rich taste of Chinese cuisine.
