Creating a spectacular Crock Pot Pepper Steak is straightforward if you follow these clear steps:

1. Slice the Steak: Cut the flank steak into thin strips, ensuring they’re uniform for even cooking.
2. Sear the Meat: In a skillet over medium-high heat, add vegetable oil. When hot, sear the steak strips for 2-3 minutes until browned but not fully cooked. Transfer to the crock pot.
3. Prepare Vegetables: In the same skillet, sauté the sliced onions, red and green bell peppers, and minced garlic for 3-4 minutes until slightly softened. Add to the crock pot.
4. Make the Sauce: In a bowl, whisk together the soy sauce, beef broth, brown sugar, ground ginger, and black pepper until combined.
5. Combine Ingredients: Pour the sauce over the steak and vegetables in the crock pot. Mix gently to ensure everything is well coated.
6. Cook: Set the crock pot to low for 6 hours or high for 3 hours, allowing the flavors to meld and the meat to become tender.
7. Thicken the Sauce: About 30 minutes before serving, whisk together cornstarch with a few tablespoons of cold water in a small bowl. Add to the crock pot and mix well. Cover and allow the sauce to thicken.
8. Taste and Adjust: Before serving, taste the dish and adjust the seasoning with salt or additional soy sauce if desired.
9. Prepare Rice or Noodles: Cook white rice or noodles according to package instructions to serve alongside the dish.
