11 - 1 tsp toasted sesame oil
12 - 2 cloves garlic, minced
13 - 1 tsp fresh ginger, grated
14 - 1/4 tsp red pepper flakes (optional)

→ The Thickening Finish

15 - 3 tbsp cornstarch
16 - 1/4 cup cold water

# Instructions:

01 - Thinly slice 1 1/2 lbs flank steak against the grain. Season with 1/2 tsp black pepper and salt to taste. Slice 1 large yellow onion, 2 green bell peppers, and 1 red bell pepper. This initial prep is key for your Easy Slow Cooker Pepper Steak Recipe.
02 - In a medium bowl, whisk together 1/2 cup low-sodium soy sauce, 1 cup beef broth, 2 tbsp packed light brown sugar, 1 tbsp rice vinegar, 1 tsp toasted sesame oil, 2 minced cloves garlic, 1 tsp grated fresh ginger, and 1/4 tsp red pepper flakes (if using).
03 - Place the seasoned flank steak, sliced yellow onion, and bell peppers into a 6-quart slow cooker. Pour the whisked sauce mixture evenly over the ingredients. Ensure everything is well distributed for a flavorful Easy Slow Cooker Pepper Steak Recipe.
04 - Cover the slow cooker and cook on LOW for 5-6 hours, or until the steak is tender and easily shredded. Avoid lifting the lid frequently to maintain consistent temperature and moisture for the best results.
05 - In a small bowl, whisk together 3 tbsp cornstarch and 1/4 cup cold water until smooth. Stir this cornstarch slurry into the slow cooker. Increase the heat to HIGH, cover, and cook for another 15-20 minutes, or until the sauce has thickened.
06 - Stir the thickened Easy Slow Cooker Pepper Steak Recipe gently. Serve immediately over steamed white rice or noodles, garnished with fresh chopped green onions if desired. Enjoy this comforting and easy meal!

# Notes:

01 - For a leaner option, you can substitute flank steak with top round or sirloin steak, ensuring it's still thinly sliced against the grain for tenderness.
02 - This pepper steak is fantastic served over steamed jasmine rice, brown rice, or even egg noodles. A sprinkle of sesame seeds or chopped green onions adds a nice finish.
03 - Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave.
04 - For an extra layer of flavor, consider searing the flank steak in a hot pan for 2-3 minutes per side before adding it to the slow cooker. This creates a delicious crust.
