Ingredients

Tips & Variations

• To keep peppers crunchier, add them midway through cooking instead of at the start.
• Substitute flank steak with sirloin or skirt steak for different textures.
• Adjust brown sugar based on your preferred sweetness level.
• Add a splash of rice vinegar or a pinch of red pepper flakes for extra tang or heat.

Storage

Store leftover pepper steak in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stove over low heat to avoid overcooking the beef. The flavors often deepen after a day, making leftover servings even tastier.

• For firmer bell peppers, add them during the last 1–2 hours of cooking instead of at the beginning.
• You can substitute beef broth with water if you prefer a lighter sauce.
• Adjust the brown sugar quantity to suit your desired level of sweetness.
• Slicing the flank steak thinly helps it cook more quickly and become tender in the slow cooker.
• This recipe can be made a day ahead; flavors often improve after resting overnight in the refrigerator.
