(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Directions
-
Prep the Steak: Slice the beef into thin strips. If you’re using a tougher cut like flank steak, you can freeze it for 30 minutes before slicing to make it easier to cut thinly.
-
Sear the Beef: Heat the vegetable oil in a skillet over medium-high heat. Add the sliced beef in batches, searing each side for 1-2 minutes. This step helps lock in the flavor and gives the steak a nice caramelized finish.
-
Combine Ingredients: Transfer the seared beef to the Crock Pot. Add the sliced onion, bell peppers, garlic, beef broth, soy sauce, oyster sauce, brown sugar, sesame oil, and ground black pepper.
-
Cook: Cover the Crock Pot and set it on low for 6-8 hours or high for 3-4 hours, until the beef is tender and the vegetables are soft.
-
Thicken the Sauce (Optional): If you prefer a thicker sauce, combine 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl. Stir the mixture into the sauce during the last 30 minutes of cooking.
-
Serve: Once the dish is cooked, serve the pepper steak over rice or noodles for a complete meal.
